Description

[Technical Field]

[0001] (Cross-reference of related applications) This application claims priority to a Chinese invention patent application filed on 28 September 2023, titled "Transition Effect Processing Method, Apparatus, Electronic Device and Storage Medium," with application number 202311285126.3, all contents of which are incorporated into this application by reference.

[0002] (Field of invention) The embodiments of this disclosure relate to the computer technology field, and more particularly to transition effect processing methods, apparatus, electronic devices, and storage media. [Background technology]

[0003] The short video application offers not only video recording capabilities but also extended features such as adding effects, filters, and tools. For example, in the audio-video clipping process, it allows you to add an overlay transition effect between adjacent audio-video segments.

[0004] In related solutions, it is necessary to analyze adjacent audio-video segments to be processed and generate overlay transition effects between adjacent audio-video segments, which is time-consuming and labor-intensive. Furthermore, when setting up overlay transition effects, it is common to overlay parts of the content of the previous audio-video segment with parts of the content of the next audio-video segment to generate the overlay transition effect, which changes the duration of the audio-video segment after the overlay transition, affecting the audio-video clip and making it impossible to obtain the appropriate audio-video segment. [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] This disclosure provides a transition effect processing method, apparatus, electronic device, and storage medium for ensuring that the total time length of media segments does not change when an overlay transition effect is applied to two adjacent media segments. [Means for solving the problem]

[0007] According to a second aspect, an embodiment of the present disclosure further provides a transition effect processing apparatus, the apparatus comprising: a first determination module for determining a first media segment and a second media segment specified by a target transition task, wherein the second media segment is located after and adjacent to the first media segment on a target edit track; a second determination module for determining a third media segment and a fourth media segment to be placed on the target edit track in response to a first operation for triggering an overlay transition effect for a target transition task, wherein the third media segment comprises the first media segment and a first newly added segment connected after the first media segment, and the fourth media segment comprises the second media segment and a second newly added segment connected before the second media segment, wherein the positions of the first media segment and the second media segment on the target edit track do not change when the first operation is triggered; and a generation module for forming an overlay transition effect in the overlapping portion between the third media segment and the fourth media segment.

[0008] According to a third aspect, embodiments of the present disclosure further provide an electronic device comprising at least one processor and a memory communicated to the at least one processor, the memory storing a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to cause the at least one processor to execute the transition effect processing method described in any one of the embodiments above.

[0009] According to a fourth aspect, embodiments of the present disclosure further provide a computer-readable medium on which computer instructions are stored, and which, when executed by a processor, are used to implement the transition effect processing method described in any one of the above embodiments. [Effects of the Invention]

[0010] Embodiments of this disclosure create a target transition task to perform transition editing on media segments, add a first newly added segment to the end of an adjacent and connected first media segment to form a corresponding third media segment, and add a second newly added segment to the beginning of a second media segment to form a corresponding fourth media segment. This enables an overlay of a portion of the screen at the end of the third media segment corresponding to the first media segment and a portion of the screen at the beginning of the fourth media segment corresponding to the second media segment. This achieves an overlay transition effect where the screen of the next media segment gradually appears and becomes clearer as the screen of the previous media segment gradually fades out. Furthermore, because the positions of the first and second media segments in the target editing track do not change, the total time length of the two adjacent media segments after the overlay transition effect is maintained unchanged.

[0024] Figure 1 is a flowchart of a transition effect processing method according to an embodiment of the present disclosure, which applies when adding an overlay transition effect to two adjacent media segments, and this method may be performed by a transition effect processing device, which may be implemented in software and / or hardware form, and is generally integrated on any electronic device having network communication capabilities, which may be a mobile terminal, PC terminal or server, etc.

[0025] As shown in Figure 1, the transition effect processing method of the embodiment of this disclosure may include the following process.

[0026] S110 determines the first and second media segments specified by the target transition task, with the second media segment being located after and adjacent to the first media segment in the target edit track.

[0027] Referring to Figure 2a, multiple media segments are present on the target editing track of the editing interface. These media segments may be audio or video segments, and each media segment present on the target editing track may be a trimmed or untrimmed media segment. If a transition effect needs to be added between two adjacent media segments, a target transition task can be created. This task determines the first media segment 201 and the second media segment 202, and the target transition task is executed to provide a transition effect when transitioning from the first media segment 201 to the second media segment 202.

[0028] Referring to Figure 2a, the first media segment 201 and the second media segment 202 are selected and trimmed from multiple media segments present on the target editing track, and may be two adjacent media segments on the target editing track, with the second media segment 202 located after the first media segment 201 on the target editing track, and the end of the first media segment 201 connected to the beginning of the second media segment 202.

[0029] S120, in response to a first operation to trigger an overlay transition effect on a target transition task, determines a third media segment and a fourth media segment to be placed on the target edit track, wherein the third media segment consists of the first media segment and a first newly added segment that follows the first media segment along the timeline, and the fourth media segment consists of the second media segment and a second newly added segment that follows the second media segment along the timeline, and the positions of the first and second media segments on the target edit track do not change when the first operation is triggered.

[0030] Referring to Figure 2a, the target transition task triggers an overlay transition effect on the first media segment 201 and the second media segment 202, so that the overlay transition effect is applied when transitioning from the screen corresponding to the first media segment 201 to the screen corresponding to the second media segment 202. When setting up an overlay transition effect, it is generally a process in which the screen of the previous media segment and the screen of the next media segment are overlaid, with the screen of the previous media segment gradually fading away and the screen of the next media segment gradually appearing. As a result, the total duration of the media segments after the overlay transition changes, affecting the clipping of the media segments.

[0031] Therefore, referring to Figure 2b, when the application triggers the addition of an overlay transition effect to the first media segment 201 and the second media segment 202 specified by the target transition task, instead of simply overlaying the segment near the end of the first media segment 201 and the segment near the beginning of the second media segment 202, the application chooses to connect a first newly added segment 205 after the first media segment along the timeline corresponding to the target edit track, and to constitute a third media segment corresponding to the first media segment by the first newly added segment 205 and the original first media segment 201, and to connect a second newly added segment 204 before the second media segment 202 along the timeline corresponding to the target edit track, and to constitute a fourth media segment corresponding to the second media segment by the second newly added segment 204 and the original second media segment 202.

[0032] Selectively, a sequential succession relationship exists between the first newly added segment 205 and the segment at the end position of the first media segment in terms of screen continuity, and a sequential succession relationship exists between the second newly added segment 204 and the segment at the beginning position of the second media segment in terms of screen continuity.

[0033] Simultaneously, referring to Figures 2a and 2c, for the first media segment in the third media segment and the second media segment in the fourth media segment, the positions of the first and second media segments on the target edit track are kept constant before and after the first operation that triggers an overlay transition effect for the target transition task. Specifically, one first newly added segment 205 is connected after the end position of the first media segment on the target edit track, and one second newly added segment 204 is connected before the start position of the second media segment 202 on the target edit track, ensuring that the total time length of the media segments before and after the overlay transition effect does not change.

[0034] Selectively, the first newly added segment is determined based on the trimmed segment that was trimmed after the first media segment when the first media segment was formed by trimming, and the second newly added segment is determined based on the trimmed segment that was trimmed before the second media segment when the second media segment was formed by trimming.

[0035] As a selective but not limited implementation, a first operation for triggering an overlay transition effect for a target transition task includes a trigger operation on the identifier of the overlay transition effect selected in the transition effect selection area corresponding to the target transition task, the transition effect selection area corresponding to the target transition task is present when the identifier of the target transition task is triggered, and the identifier of the target transition task is configured to be present at the connection point of two adjacent media segments selected in the target edit track.

[0036] Referring to Figure 2d, adjacent identifiers for the target transition tasks corresponding to the first media segment 201 and the second media segment 202 are added to the adjacent positions of the first media segment 201 and the second media segment 202 that are present on the target editing track. In response to a trigger operation on the identifiers for the target transition tasks corresponding to the first media segment 201 and the second media segment 202, a transition effect selection area corresponding to the target transition task is displayed. The transition effect selection area is set to multiple transition effect identifiers, such as a push-in transition effect, a black flash transition effect, and a dissolve transition effect (also called an overlay transition effect). The first operation may be a trigger operation on the identifier of the overlay transition effect selected in the transition effect selection area corresponding to the target transition task.

[0037] Referring to Figure 2d, a first operation for selectively triggering an overlay transition effect for a target transition task further includes an operation to set and trigger on the transition duration in the transition effect selection area corresponding to the target transition task. For example, the transition effect selection area may further include a transition duration adjuster, which, by adjusting the progress of the transition duration adjuster, can adjust the transition duration between the first and second media segments so that the duration of the overlay transition effect formed between the third media segment corresponding to the first media segment and the fourth media segment corresponding to the second media segment is equal to the target transition duration, or the duration of the overlap between the third media segment corresponding to the first media segment and the fourth media segment corresponding to the second media segment is equal to the target transition duration.

[0038] As a selective but non-restrictive implementation, determining the first and second media segments specified by the target transition task is: The process includes the step of determining a first and second media segment specified by a target transition task in response to a second operation which involves having at least two media segments present on a target editing track and triggering a target transition task for two adjacent media segments selected in at least two media segments.

[0039] Referring to Figure 2c, in response to an operation to add media material from the material library, at least two media materials corresponding to the add operation are retrieved, and the editing interface is displayed, on which a target editing track is present, and at least two media segments formed based on the at least two media materials corresponding to the add operation are placed on the target editing track, and the media segments may be audio segments or video segments. Furthermore, adjacent first and second media segments on the target editing track are selected, a second operation of the target transition task is triggered for the two selected media segments, and the first and second media segments specified by the target transition task corresponding to the second operation are determined.

[0040] A second operation, which selectively triggers a target transition task for two adjacent media segments selected in at least two media segments, includes a trigger operation on the target transition task identifier of the two adjacent media segments selected in the target edit track, where the target transition task identifier is configured to be present at the connection point of the two adjacent media segments selected in the target edit track.

[0041] Referring to Figure 2d, adjacent first media segment 201 and second media segment 202 that are present on the target editing track have identifiers for target transition tasks corresponding to the first media segment 201 and second media segment 202 added to their adjacent positions. The second operation is a trigger operation on the target transition task identifiers corresponding to the adjacent first media segment 201 and second media segment 202 selected on the target editing track. When the trigger operation is performed on the target transition task identifiers, the transition effect selection area corresponding to the target transition task is displayed.

[0042] S130 creates an overlay transition effect in the overlapping area between the third media segment and the fourth media segment.

[0043] When selectively positioning and displaying the overlapping portion between the third and fourth media segments on the target editing track, an overlay transition effect is present in the overlapping portion between the third and fourth media segments. For example, when positioning the playhead on the target editing track to the overlapping portion between the third and fourth media segments, an overlay transition effect is present in the overlapping portion between the third and fourth media segments on the target editing track.

[0044] Selectively, when the playhead position on the target editing track is moved to a first preset time range of the third media segment, an overlay transition effect is present at the playhead position on the target editing track, with the first preset time range determined based on the overlap time between the third and fourth media segments. When the playhead position on the target editing track is moved to a second preset time range of the fourth media segment, an overlay transition effect is present at the playhead position on the target editing track, with the second preset time range determined based on the overlap time between the fourth and third media segments.

[0045] Referring to Figures 2b and 2e, in the target editing track, the overlay transition effect of the first part is present in the overlapping area between the second newly added segment 204 and the first media segment 201 in the fourth media segment, and the overlay transition effect of the second part is present in the overlapping area between the first newly added segment 205 and the second media segment 202 in the third media segment. The overlay transition effects of the first part and the overlay transition effects of the second part together form the overlay transition effect of the first media segment 201 and the second media segment 202. For example, if the playhead is moved to a position close to the second media segment on the first media segment in the target editing track, the screen of the second newly added segment 204, which is connected in front of the first media segment, will faintly appear on the screen of the first media segment 201 in Figure 2e.

[0046] Based on the above embodiment, after selectively forming an overlay transition effect in the overlapping portion between the third media segment and the fourth media segment, The process further includes generating a target output result based on a third media segment and a fourth media segment, where the target output result is either a draft preview before exporting the media segments or the target video after exporting the media segments.

[0047] Referring to Figures 2b and 2e, a preview area is displayed on the editing interface, and a draft preview of the third and fourth media segments present on the target editing track can be previewed and played back using the preview player in the preview area before they are exported. When the time range corresponding to the overlap between the third and fourth media segments is previewed and played back using the preview player in the preview area, an overlay transition effect is present. Referring to Figures 2b and 2e, in response to the video export operation of the third and fourth media segments, the third and fourth media segments on the target editing track can be combined and exported as video segments according to the timeline order corresponding to the target editing track, and the target video of the overlay transition effect is present in the overlap between the third and fourth media segments.

[0048] The technical invention of the embodiment of this disclosure creates a target transition task to perform transition editing on media segments, adds a first newly added segment to the end of an adjacent and connected first media segment to form a corresponding third media segment, and adds a second newly added segment to the beginning of a second media segment to form a corresponding fourth media segment. This enables an overlay of a portion of the screen at the end of the third media segment corresponding to the first media segment and a portion of the screen at the beginning of the fourth media segment corresponding to the second media segment. This achieves an overlay transition effect where the screen of the next media segment gradually appears and becomes clearer as the screen of the previous media segment gradually fades out and disappears. Furthermore, because the positions of the first and second media segments in the target editing track do not change, the total time length of the two adjacent media segments after the overlay transition effect is maintained unchanged.

[0049] Figure 3 is a flowchart of another transition effect processing method according to an embodiment of the present disclosure, the technical proposal of this embodiment further optimizes the process of determining the third and fourth media segments to be placed on the target editing track in the above embodiment based on the above embodiment, and this embodiment can be combined with each of the selective solutions in the one or more of the above embodiments.

[0050] As shown in Figure 3, the transition effect processing method of the embodiment of this disclosure may include the following process.

[0051] S310 determines the first media segment and the second media segment specified by the target transition task, wherein the second media segment is located after and adjacent to the first media segment in the target edit track.

[0052] S320, in response to a first operation to trigger an overlay transition effect on the target transition task, determines the target transition duration corresponding to the target transition task.

[0053] S330, based on the target transition time length and the time length of the first media segment, the media segment is trimmed from the start to the end of the first media segment in the first media material to obtain a third media segment to be placed on the target editing track. The first media material is the pre-trimmed media segment used when forming the first media segment by trimming, and the third media segment consists of the first media segment and a first newly added segment that follows the first media segment.

[0054] Referring to Figure 4, a first media material 206 corresponding to the first media segment is determined, and the first media material 206 is the media segment before trimming used when forming the first media segment by trimming. By trimming the media segment in the first media material 206 from the starting point to the ending point of the first media segment 201 (for example, from left to right in the first media material 206 in Figure 4), it is possible to replenish the media segment after the first media segment by trimming the media segment in the first media material 206, and in this way the first newly added segment 205 is connected after the first media segment 201, and a third media segment 208 can be obtained which consists of the first media segment 201 and the first newly added segment 205 connected after the first media segment.

[0055] S340, based on the target transition time length and the time length of the second media segment, the second media material is trimmed from the end point toward the start point of the second media segment to obtain a fourth media segment placed on the target editing track. The second media material is the pre-trimmed media segment used when forming the second media segment by trimming. The fourth media segment consists of the second media segment and a second newly added segment that precedes the second media segment. When the first operation is triggered, the positions of the first media segment and the second media segment on the target editing track do not change.

[0056] Referring to Figure 4, a second media material 207 corresponding to the second media segment is determined, and the second media material 207 is the media segment before trimming that is used when forming the second media segment by trimming. In the second media material 207, the media segment is trimmed from the end point of the second media segment 202 toward the beginning point (for example, in Figure 4, the second media material 207 is in the direction from right to left), and by trimming the media segment in the second media material 207, it is realized that a media segment is added before the second media segment, and in this way a second newly added segment 204 is connected before the second media segment 202, and a fourth media segment 209 can be obtained which consists of the second media segment 202 and the second newly added segment 204 connected before the second media segment.

[0057] Selectively, the duration of the first newly added segment in the third media segment is equal to half the target transition duration, and the duration of the second newly added segment in the fourth media segment is equal to half the target transition duration. Selectively, the duration of the first newly added segment in the third media segment is less than half the target transition duration, the duration of the second newly added segment in the fourth media segment is greater than half the target transition duration, and the sum of the durations of the first and second newly added segments is equal to the target transition duration. Selectively, the duration of the first newly added segment in the third media segment is greater than half the target transition duration, the duration of the second newly added segment in the fourth media segment is less than half the target transition duration, and the sum of the durations of the first and second newly added segments is equal to the target transition duration.

[0058] Selectively, a third media segment placed on the target editing track may be represented by the start and end times of the first media segment on the target editing track, and the start and end times of the third media segment relative to the first media material, where the first media material is the untrimmed media segment used when trimming to form the first media segment. A fourth media segment placed on the target editing track may be represented by the start and end times of the second media segment on the target editing track, and the start and end times of the fourth media segment relative to the second media material, where the second media material is the untrimmed media segment used when trimming to form the second media segment.

[0059] As a selective but not limited implementation, the first newly added segment is determined based on the first trimmed segment, the first trimmed segment is a media segment trimmed after the first media segment when the first media material is trimmed to form the first media segment, and the first media material is the untrimmed media segment used when the first media segment is formed by trimming.

[0060] Selectively, the duration of the first newly added segment following the first media segment is the duration of the first preset duration, the duration of the second newly added segment following the second media segment is the duration of the second preset duration, the sum of the durations of the first and second preset durations is equal to the target transition duration, and the durations of the first and second preset durations are either the same or different. Based on this, if the duration of the first trimming segment is greater than or equal to the duration of the first preset duration, the first newly added segment consists of a portion of the media segment in the first trimming segment. In this case, the duration of the media segment trimmed from after the end of the first media segment in the first media material is greater than or equal to the duration of the first preset duration, and the media segment replenishment after the first media segment can be fully performed simply by using the first trimming segment.

[0061] Selectively, the duration of the first newly added segment following the first media segment is the first preset duration, and the duration of the second newly added segment following the second media segment is the second preset duration. The sum of the first and second preset durations is equal to the target transition duration, and the first and second preset durations are either the same or different. Based on this, if the duration of the first trimming segment is less than the first preset duration, the first newly added segment consists of all media segments in the first trimming segment and the end frame in the first trimming segment. In this case, the duration of the media segments trimmed after the end of the first media segment in the first media material is less than the first preset duration, indicating that using only the first trimming segment is insufficient to fully replenish the media segments after the first media segment, and therefore further replenishment by the end frame in the first trimming segment is necessary.

[0062] Referring to Figure 2b, taking the example that the first preset time length is equal to the second preset time length, if the time length of the first trimming segment is less than the first preset time length (half of the target transition time length), the second newly added segment 204 will configure the first trimming segment and the end frame in the first trimming segment as static frames, and the time length of the second newly added segment will be equal to half of the target transition time length, where the time length of the second newly added segment satisfies Tstatic = (Ttransition / 2) - Ttrim, where Tstatic represents the time length for which the end frame in the first trimming segment is a static frame, Ttransition represents half of the time length of the second newly added segment, and Ttrim represents the time length of the first trimming segment. Here, since both the transition time and the time of the trimmed first segment are obtained at the UI layer, when adjusting the transition time, the UI layer only needs to calculate the adjustment screen in real time, and it locks and executes when the user releases their finger.

[0063] As a selective but not limited implementation, a second newly added segment is determined based on a second trimmed segment, the second trimmed segment being a media segment trimmed before the second media segment when forming the second media segment by trimming the second media material, and the second media material being the untrimmed media segment used when forming the second media segment by trimming.

[0064] Selectively, the duration of the first newly added segment following the first media segment is the duration of the first preset duration, the duration of the second newly added segment following the second media segment is the duration of the second preset duration, the sum of the durations of the first and second preset durations is equal to the target transition duration, and the durations of the first and second preset durations are either the same or different. Based on this, if the duration of the second trimming segment is greater than or equal to the duration of the second preset duration, the second newly added segment consists of some media segments from the second trimming segment. In this case, the duration of the media segments trimmed from before the start of the second media segment in the second media material is greater than or equal to the duration of the second preset duration, and the media segment replenishment before the second media segment can be fully performed simply by using the second trimming segment.

[0065] Selectively, the duration of the first newly added segment following the first media segment is the first preset duration, and the duration of the second newly added segment following the second media segment is the second preset duration. The sum of the first and second preset durations is equal to the target transition duration, and the first and second preset durations are either the same or different. Based on this, if the duration of the second trimming segment is less than the second preset duration, the second newly added segment consists of all the media segments in the second trimming segment and the start frame in the second trimming segment. In this case, the duration of the media segments trimmed from before the start of the second media segment in the second media material is less than the second preset duration, indicating that using only the second trimming segment is insufficient to fully replenish the media segments before the second media segment, and therefore further replenishment is required by the start frame in the second trimming segment.

[0066] Selectively, if the time length of the first trimming segment is zero, the first newly added segment consists only of static frames cut from the first media segment, and the first trimming segment is the media segment trimmed after the first media segment when the first media material is trimmed to form the first media segment. If the time length of the second trimming segment is zero, the second newly added segment consists only of static frames cut from the second media material, and the time length of the second trimming segment is the media segment trimmed before the second media segment when the second media material is trimmed to form the second media segment.

[0067] Selectively, the calculation of the start time TrimIn for the first media material in the third media segment and the start time TrimIn for the second media material in the fourth media segment is as follows:

[0068] The start time for the first media material in the third media segment can be calculated directly using TrimIn:source_time_range().start()*speed(). The start time of the fourth media segment relative to the first media material is TrimIn: (1) If the target transition start time of the first and second media segments is less than the start time of the second media material, the time length of the second trimmed segment trimmed from the second media material will be less than half the target transition time length, and static frame replenishment will be required, and the start time of the third media segment relative to the first media material will be D TrimIn =T startTransition -(T startTarget -f(t)T startSource (2) If the target transition start times of the first media segment and the second media segment are equal to or greater than the start time of the second media material, the duration of the second trimmed segment, which is trimmed from the second media material, is greater than half of the target transition duration, and static frame replenishment is unnecessary, and the start time of the third media segment relative to the first media material is D TrimIn =T startTransition -(T startTarget -f(t)T startSource This can be expressed as follows:

[0069] Selectively, the calculation of the TrimOut endpoint for the first media material in the third media segment and the TrimOut endpoint for the second media material in the fourth media segment is as follows:

[0070] The end point time TrimOut for the first media material of the third media segment is as follows.

[0071] D TrimOut =f(t)Ts tartSource +T durationSource +T durationTransiti / 2.

[0072] The end point time TrimOut for the second media material of the fourth media segment is as follows.

[0073] D TrimOut =f(t)T startSource +T durationSource Here, for the variable speed coefficient f(t): in the case of curve speed change, this f(t) value is the reciprocal of the speed change value at the critical point of non-transition; in the case of normal speed change, this f(t) value is the reciprocal of the speed change value.

[0074] S350 forms an overlay transition effect in the overlapping part between the third media segment and the fourth media segment.

[0075] As a selective but non-limiting implementation form, generating a target output result based on the third media segment and the fourth media segment includes the following steps A1 to A3.

[0076] Step A1, in response to a third operation that triggers a speed change setting for the first media segment in the third media segment on the target edit track, add a first curve speed change to the first media segment in the third media segment and add a speed change at the end point corresponding to the first curve speed change to the first newly added segment in the third media segment.

[0077] Selectively, the third operation includes a trigger operation on an identifier for setting the shift, which is present in the third media segment on the target editing track in relation to the first media segment, and the identifier for setting the shift, which is present in relation to the first media segment, is present based on the selection operation of the first media segment in the third media segment on the target editing track.

[0078] Referring to Figure 5a, the identifier for setting the gear shift, which is present in the first media segment, is present based on the selection operation of the first media segment 201 in the third media segment on the target editing track, and is, for example, the identifier for normal gear shift and curved gear shift. Furthermore, a trigger operation is performed on the identifier for setting the gear shift, which is present in the third media segment on the target editing track in the first media segment 201.

[0079] Referring to Figure 5b, the first media segment is presented in the third media segment, and a first curved speed change is added to the first media segment in the third media segment, but the terminal endpoint velocity of the first curved speed change used in the first media segment before transitioning to the first newly added segment that follows the first media segment is added, and the speed change acts on the first newly added segment portion that follows the first media segment. Here, the first curved speed change acts on the first media segment, and after cutting or stretching, the first curved speed change acts on the first media segment in the third media segment. After the transition is added, the stretched portion, trimmed portion and static frame portion are generated, and the speed change rate of the first newly added segment of the extended portion is the terminal endpoint velocity value of the first curved speed change.

[0080] Step A2, in response to the fourth operation which triggers a speed change setting for the second media segment in the fourth media segment on the target editing track, a second curve speed change is added to the second media segment in the fourth media segment and a start / end speed change corresponding to the second curve speed change is added to the second newly added segment in the fourth media segment.

[0081] Selectively, the fourth operation includes a trigger operation on an identifier for setting the shift, which is present in the fourth media segment on the target editing track in relation to the second media segment, and the identifier for setting the shift, which is present in relation to the second media segment, is present based on the selection operation of the second media segment on the fourth media segment on the target editing track.

[0082] Referring to Figure 5b, the second media segment is presented in the fourth media segment, and a second curved speed change is added to the second media segment in the fourth media segment, but the start and end points of the second curved speed change used in the second media segment before the transition to the second newly added segment that connects to the second media segment are added, and the speed change acts on the second newly added segment portion that connects to the second media segment. Here, the second curved speed change acts on the second media segment, and after cutting or stretching, the second curved speed change acts on the second media segment in the fourth media segment. After the transition is added, the stretched portion, trimmed portion and static frame portion are generated, and the speed change rate of the second newly added segment of the extended portion is the start and end point velocity value of the second curved speed change.

[0083] Step A3 generates a target output result based on the third media segment, the corresponding speed change for the third media segment, the fourth media segment, and the corresponding speed change for the fourth media segment, and the target output result is either a draft preview before exporting the media segments or the target video after exporting the media segments.

[0084] Selectively, the shift panel extends the newly added segment portion according to the corresponding time length ratio. The start / end point (left endpoint) of the connected and extended second newly added segment or the end point (right endpoint) of the first newly added segment cannot be adjusted. A shift point cannot be added between the start / end point (left endpoint) of the second newly added segment portion and the start point of the second media segment. By adjusting the shift rate of the start point of the second media segment, the shift rate of the left endpoint of the second newly added segment portion can be changed, and the start / end points of the second newly added segment can be recalculated according to the new shift rate. A shift point cannot be added between the end point (right endpoint) of the first newly added segment portion and the end point of the first media segment. By adjusting the shift rate of the end endpoint of the first media segment, the shift rate of the right endpoint of the first newly added segment can be changed, and the end point of the first newly added segment can be recalculated according to the new rate.

[0085] As a selective but non-restrictive implementation, the system further includes performing keying, destrobbing, noise reduction, image stabilization, and motion tracking on the first newly added segment and the second newly added segment before generating the target output result based on the third media segment, the speed change corresponding to the third media segment, the fourth media segment, and the speed change corresponding to the fourth media segment.

[0086] The technical invention of the embodiment of this disclosure creates a target transition task to perform transition editing on media segments, adds a first newly added segment to the end of an adjacent and connected first media segment to form a corresponding third media segment, and adds a second newly added segment to the beginning of a second media segment to form a corresponding fourth media segment. This enables an overlay of a portion of the screen at the end of the third media segment corresponding to the first media segment and a portion of the screen at the beginning of the fourth media segment corresponding to the second media segment. This achieves an overlay transition effect where the screen of the next media segment gradually appears and becomes clearer as the screen of the previous media segment gradually fades out and disappears. Furthermore, because the positions of the first and second media segments in the target editing track do not change, the total time length of the two adjacent media segments after the overlay transition effect is maintained unchanged.

[0095] Based on the above embodiment, selectively, the first newly added segment is determined based on the first trimmed segment, the first trimmed segment being a media segment trimmed after the first media segment when the first media material is trimmed to form the first media segment, and the second newly added segment is determined based on the second trimmed segment, the second trimmed segment being a media segment trimmed before the second media segment when the second media material is trimmed to form the second media segment.
