Description

Transition special effects processing method, device, electronic device and storage medium

[0001] This application claims priority to the Chinese invention patent application entitled “Transition special effects processing method, device, electronic device and storage medium” filed on September 28, 2023, with application number 202311285126.3. The entire contents of that application are incorporated herein by reference. Technical Field

[0002] The embodiments of the present disclosure relate to the field of computer technology, and in particular to a method, device, electronic device, and storage medium for processing transition special effects. Background Art

[0003] Short video applications not only have video shooting functions, but also provide extended functions such as adding special effects, filters, props, etc. For example, during the audio and video editing process, superimposed transition effects can be added between adjacent audio and video clips.

[0004] In the related scheme, it is necessary to analyze the adjacent audio and video clips to be processed and generate superimposed transition effects between the adjacent audio and video clips, which is time-consuming and labor-intensive. Moreover, when configuring the superimposed transition effect, part of the content of the previous audio and video clip is usually superimposed with part of the content of the next audio and video clip to generate the superimposed transition effect. As a result, the length of the audio and video clip after the superimposed transition will change, which affects the audio and video editing and makes it impossible to obtain suitable audio and video clips.

[0037] Figure 1 is a flow chart of a transition special effect processing method provided by an embodiment of the present disclosure. The embodiment of the present disclosure is applicable to the situation where an overlaid transition special effect is added to two adjacent media segments. The method can be executed by a transition special effect processing device. The transition special effect processing device can be implemented in the form of software and / or hardware and is generally integrated on any electronic device with network communication function, which can be a mobile terminal, PC or server, etc.

[0038] As shown in FIG1 , the method for processing transition effects according to an embodiment of the present disclosure may include the following steps:

[0039] S110 : Determine a first media segment and a second media segment specified by a target transition task, where the second media segment is located after and adjacent to the first media segment on the target editing track.

[0040] Referring to Figure 2a, a target editing track in the editing interface displays multiple media clips. The media clips can be audio clips or video clips, and each media clip displayed on the target editing track can be a cropped or uncropped media clip. When a transition effect is required between two adjacent media clips, a target transition task can be created, and the first media clip 201 and the second media clip 202 specified by the target transition task can be determined. By executing the target transition task, the transition effect is achieved when switching from the first media clip 201 to the second media clip 202.

[0041] Referring to Figure 2a, the first media segment 201 and the second media segment 202 can be selected and trimmed from multiple media segments presented on the target editing track, and are two adjacent media segments on the target editing track. The second media segment 202 is located after the first media segment 201 on the target editing track, and the end of the first media segment 201 is connected to the beginning of the second media segment 202.

[0042] S120. In response to a first operation for triggering a superimposed transition effect for a target transition task, determine a third media segment and a fourth media segment placed on a target editing track, wherein the third media segment is composed of a first media segment and a first newly added segment connected after the first media segment along the timeline, and the fourth media segment is composed of a second media segment and a second newly added segment connected before the second media segment along the timeline. When the first operation is triggered, the positions of the first media segment and the second media segment on the target editing track remain unchanged.

[0043] Referring to Figure 2a , an overlay transition effect is triggered for the first media segment 201 and the second media segment 202 specified in the target transition task, thereby providing an overlay transition effect when transitioning from the frame corresponding to the first media segment 201 to the frame corresponding to the second media segment 202. Because the overlay transition effect typically overlays the frame of the preceding media segment with the frame of the following media segment, gradually fading away and revealing the frame of the following media segment, the total duration of the media segment after the overlay transition changes, impacting the editing of the media segments.

[0044] To this end, referring to Figure 2b, when the present application triggers the addition of an overlay transition effect to the first media segment 201 and the second media segment 202 specified for the target transition task, it no longer simply overlays the partial segment of the first media segment 201 near the end position with the partial segment of the second media segment 202 near the beginning position, but instead selects to connect a first newly added segment 205 after the first media segment along the timeline corresponding to the target editing track, and forms a third media segment corresponding to the first media segment through the first newly added segment 205 and the original first media segment 201, and at the same time connects a second newly added segment 204 before the second media segment 202 along the timeline corresponding to the target editing track, and forms a fourth media segment corresponding to the second media segment through the second newly added segment 204 and the original second media segment 202.

[0045] Optionally, the first newly added segment 205 and the segment at the end position of the first media segment have a front-to-back relationship in terms of picture continuity, and the second newly added segment 204 and the segment at the beginning position of the second media segment have a front-to-back relationship in terms of picture continuity.

[0046] At the same time, 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 media segment and the second media segment on the target editing track are kept unchanged before and after the first operation of triggering the superimposed transition effect on the target transition task, that is, a first newly added segment 205 is connected after the end position of the first media segment placed on the target editing track, and a second newly added segment 204 is connected before the beginning position of the second media segment 202 placed on the target editing track, to ensure that the total length of the media segments remains unchanged before and after the superimposed transition effect is performed.

[0047] Optionally, the second newly added segment is determined based on a cropped segment that is cropped after the first media segment when the first media segment is formed by cropping, and the second newly added segment is determined based on a cropped segment that is cropped before the second media segment when the second media segment is formed by cropping.

[0048] As an optional but non-limiting implementation method, the first operation for triggering the superimposed transition effect for the target transition task includes a triggering operation for the identifier of the superimposed 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 presented when the identifier of the target transition task is triggered, and the identifier of the target transition task is configured to be presented at the connection position of the two adjacent media clips selected on the target editing track.

[0049] Referring to Figure 2d, the adjacent positions of the first media segment 201 and the second media segment 202 presented on the target editing track are marked with the identifiers of the target transition tasks corresponding to the first media segment 201 and the second media segment 202. In response to a triggering operation on the identifiers of 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 includes multiple transition effect identifiers, such as a push transition effect, a flash-to-black transition effect, and a dissolve transition effect (also known as an overlay transition effect). The first operation can specifically be a triggering operation of selecting the identifier of the overlay transition effect in the transition effect selection area corresponding to the target transition task.

[0050] Referring to FIG2d , optionally, the first operation for triggering the superimposed transition effect for the target transition task also includes an operation for configuring and triggering the transition duration in the transition effect selection area corresponding to the target transition task. For example, a transition duration adjuster is further configured in the transition effect selection area, and progress adjustment in the transition duration adjuster can adjust the transition duration between the first media segment and the second media segment so that the duration of the superimposed 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 overlapping portion 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.

[0051] As an optional but non-limiting implementation, determining the first media segment and the second media segment specified by the target transition task includes the following steps:

[0052] At least two media segments are presented on a target editing track, and in response to a second operation of triggering a target transition task on two adjacent media segments selected from the at least two media segments, a first media segment and a second media segment specified by the target transition task are determined.

[0053] Referring to Figure 2c, in response to an operation to add a media material from the material library, at least two media materials corresponding to the addition operation are retrieved and an editing interface is displayed. A target editing track is presented in the editing interface, and at least two media segments formed from the at least two media materials corresponding to the addition operation are placed on the target editing track. The media segments can be audio or video segments. Furthermore, a first media segment and a second media segment adjacent to each other on the target editing track are selected, and a second operation of a target transition task is triggered for the two selected media segments. The first and second media segments designated by the target transition task corresponding to the second operation are determined.

[0054] Optionally, the second operation of triggering the target transition task for two adjacent media segments selected in at least two media segments includes a triggering operation of an identifier of the target transition task for two adjacent media segments selected on the target editing track; the identifier of the target transition task is configured to be presented at the connection position of the two adjacent media segments selected on the target editing track.

[0055] Referring to Figure 2d , the identifiers of the target transition tasks corresponding to the first and second media segments 201 and 202 are added to the adjacent positions of the adjacent first and second media segments 201 and 202 presented on the target editing track. The second operation is a triggering operation on the identifier of the target transition task corresponding to the adjacent first and second media segments 201 and 202 selected on the target editing track. When the triggering operation is performed on the identifier of the target transition task, a transition effect selection area corresponding to the target transition task is displayed.

[0056] S130: Form a superimposed transition effect at the overlapping portion between the third media segment and the fourth media segment.

[0057] Optionally, when the playhead is positioned on the target editing track to display the overlapping portion between the third media segment and the fourth media segment, an overlay transition effect is presented on the overlapping portion between the third media segment and the fourth media segment. For example, when the playhead is positioned on the target editing track to display the overlapping portion between the third media segment and the fourth media segment, an overlay transition effect is presented on the overlapping portion between the third media segment and the fourth media segment on the target editing track.

[0058] Optionally, when the playback head position is positioned within the first preset time range of the third media segment on the target editing track, an overlay transition effect is presented at the playback head position on the target editing track, and the first preset time range is determined based on the time of the overlapping part of the third media segment and the fourth media segment; when the playback head position is positioned within the second preset time range of the fourth media segment on the target editing track, an overlay transition effect is presented at the playback head position on the target editing track, and the second preset time range is determined based on the time of the overlapping part of the fourth media segment and the third media segment.

[0059] 2b and 2e , on the target editing track, the overlapping portion of the second newly added segment 204 and the first media segment 201 in the fourth media segment presents a first portion of an overlay transition effect, and the overlapping portion of the first newly added segment 205 and the second media segment 202 in the third media segment presents a second portion of an overlay transition effect. Together, the first and second portions of the overlay transition effect form the overlay transition effect between the first media segment 201 and the second media segment 202. For example, when the playhead is moved to a position on the first media segment near the second media segment on the target editing track, the second newly added segment 204, which is connected to the first media segment, appears faintly on the screen of the first media segment 201 in FIG. 2e .

[0060] Based on the above embodiment, optionally, after forming a superimposed transition effect on the overlapping portion between the third media segment and the fourth media segment, the method further includes:

[0061] A target output result is generated based on the third media segment and the fourth media segment. The target output result is a draft preview before the media segment is exported or a target video after the media segment is exported.

[0062] Referring to Figures 2b and 2e, a preview area is displayed on the editing interface. A preview player in the preview area can be used to preview and play the corresponding pre-export draft previews of the third and fourth media segments presented on the target editing track. During the time range corresponding to the overlapping portion between the third and fourth media segments, a superimposed transition effect is presented when previewed and played using the preview player in the preview area. Referring to Figures 2b and 2e, in response to a video export operation for the third and fourth media segments, the third and fourth media segments on the target editing track can be synthesized into video segments according to the timeline sequence corresponding to the target editing track, and a target video with a superimposed transition effect presented in the overlapping portion between the third and fourth media segments is exported.

[0063] The technical solution of the embodiment of the present disclosure creates a target transition task for transition editing of media segments, and forms a corresponding third media segment by adding a first newly added segment at the end of the adjacent and end-connected first media segment and forms a corresponding fourth media segment by adding a second newly added segment at the beginning of the second media segment, so that part of the picture at the end of the third media segment corresponding to the first media segment and part of the picture at the beginning of the fourth media segment corresponding to the second media segment can be superimposed together, so that when the picture of the previous media segment gradually fades away, the picture of the next media segment gradually appears and is clearly superimposed on the transition effect. At the same time, since the positions of the first media segment and the second media segment in the target editing track remain unchanged, the total duration of the two adjacent media segments after the superimposed transition effect can be maintained unchanged.

[0064] Figure 3 is a flow chart of another method for processing transition special effects provided by an embodiment of the present disclosure. The technical solution of this embodiment further optimizes the process of determining the third media segment and the fourth media segment to be placed on the target editing track in the aforementioned embodiment on the basis of the aforementioned embodiment. This embodiment can be combined with various optional solutions in one or more of the aforementioned embodiments.

[0065] As shown in FIG3 , the method for processing transition effects according to an embodiment of the present disclosure may include the following steps:

[0066] S310: Determine a first media segment and a second media segment specified by a target transition task, where the second media segment is located after and adjacent to the first media segment on a target editing track.

[0067] S320: In response to a first operation for triggering a superimposed transition effect on a target transition task, determining a target transition duration corresponding to the target transition task.

[0068] S330. Based on the target transition duration and the duration of the first media segment, media segments are cut from the starting point of the first media segment toward the ending point in the first media material to obtain a third media segment placed in the target editing track. The first media material is the media segment before trimming used when the first media segment is formed by trimming. The third media segment consists of the first media segment and a first newly added segment connected after the first media segment.

[0069] 4 , a second media material 206 corresponding to the first media segment is determined. The first media material 206 is the pre-cropped media segment used when cropping to form the first media segment. Media segments are cut from the first media segment 201's starting point toward the end point (e.g., from left to right in the first media material 206 of FIG. 4 ). By cutting media segments from the first media material 206, media segments are added after the first media segment. This allows the first added segment 205 to be connected after the first media segment 201, resulting in a third media segment 208 consisting of the first media segment 201 and the first added segment 205 connected after the first media segment.

[0070] S340. Based on the target transition duration and the duration of the second media segment, the media segment is cut from the end point of the second media segment toward the starting point in the second media material to obtain a fourth media segment placed in the target editing track. The second media material is the media segment before cropping used when forming the second media segment by cropping. The fourth media segment consists of the second media segment and a second newly added segment connected before the second media segment. When the first operation is triggered, the positions of the first media segment and the second media segment in the target editing track remain unchanged.

[0071] 4 , the second media material 207 corresponding to the second media segment is determined. The second media material 207 is the pre-cropped media segment used when cropping to form the second media segment. Media segments are cut from the second media material 207 starting from the end point of the second media segment 202 toward the start point (e.g., from right to left in the sixth media segment 207 in FIG4 ). By cutting media segments from the second media material 207, media segments are added before the second media segment. This allows the second added segment 204 to be connected before the second media segment 202, resulting in a fourth media segment 209 consisting of the second media segment 202 and the second added segment 204 connected before the second media segment.

[0072] Optionally, the duration of the first newly added segment in the third media segment is equal to half of the target transition duration, and the duration of the second newly added segment in the fourth media segment is equal to half of the target transition duration. Optionally, the duration of the first newly added segment in the third media segment is less than half of the target transition duration, the duration of the second newly added segment in the fourth media segment is greater than half of the target transition duration, and the sum of the duration of the first newly added segment and the duration of the second newly added segment is equal to the target transition duration. Optionally, the duration of the first newly added segment in the third media segment is greater than half of the target transition duration, the duration of the second newly added segment in the fourth media segment is less than half of the target transition duration, and the sum of the duration of the first newly added segment and the duration of the second newly added segment is equal to the target transition duration.

[0073] Optionally, the third media segment placed on the target editing track can be represented by the start and end times of the first media segment on the target editing track, as well as the start and end times of the third media segment relative to the first media material. The first media material is the media segment before trimming used when the first media segment is formed by trimming. The fourth media segment placed on the target editing track can be represented by the start and end times of the second media segment on the target editing track, as well as the start and end times of the fourth media segment relative to the second media material. The second media material is the media segment before trimming used when the second media segment is formed by trimming.

[0074] As an optional but non-limiting implementation method, the first newly added segment is determined based on the first cropped segment, where the first cropped segment is a media segment cropped after the first media segment when the first media segment is formed by cropping the first media material, and the first media material is the media segment before cropping used when the first media segment is formed by cropping.

[0075] Optionally, the duration of the first newly added segment connected after the first media segment is the first preset duration, the duration of the second newly added segment connected before the second media segment is the second preset duration, the sum of the first preset duration and the second preset duration is equal to the target transition duration, and the first preset duration is the same as or different from the second preset duration. On this basis, when the duration of the first cropped segment is greater than or equal to the first preset duration, the first newly added segment is composed of part of the media segments in the first cropped segment. At this time, the duration of the media segment cropped from the end of the first media segment in the first media material is greater than or equal to the first preset duration, and the media segment can be supplemented after the first media segment by using only the first cropped segment.

[0076] Optionally, the duration of the first newly added segment connected after the first media segment is the first preset duration, the duration of the second newly added segment connected before the second media segment is the second preset duration, the sum of the first preset duration and the second preset duration is equal to the target transition duration, and the first preset duration is the same as or different from the second preset duration. On this basis, when the duration of the first cropped segment is less than the first preset duration, the first newly added segment is composed of all media segments in the first cropped segment and the end frame in the first cropped segment. At this time, the duration of the media segment cropped from the end of the first media segment in the first media material is less than the first preset duration, indicating that it is impossible to complete the media segment after the first media segment using only the first cropped segment, and therefore it is necessary to further supplement it with the help of the end frame in the first cropped segment.

[0077] Referring to FIG2b, taking the first preset duration equal to the second preset duration as an example, when the duration of the first cropped segment is less than the first preset duration (half of the target transition duration), the second newly added segment 204 includes the first cropped segment and the end frame in the first cropped segment as a static frame, and the duration of the second newly added segment is equal to half of the target transition duration, wherein the duration of the second newly added segment satisfies the following: Tstatic=(Ttransition / 2)-Ttrim, Tstatic represents the duration of the end frame in the first cropped segment as a static frame, Ttransition represents half of the duration of the second newly added segment, and Ttrim represents the duration of the first cropped segment. Among them, the transition duration and the duration of the cropped first cropped segment can be obtained in the UI layer, so when adjusting the transition duration, the UI layer calculates the adjustment screen in real time and locks it when releasing the hand.

[0078] As an optional but non-limiting implementation method, the second newly added segment is determined based on the second cropped segment, where the second cropped segment is a media segment that is cropped before the second media segment when the second media segment is formed by cropping the second media material, and the second media material is the media segment before cropping used when the second media segment is formed by cropping.

[0079] Optionally, the duration of the first newly added segment connected after the first media segment is the first preset duration, the duration of the second newly added segment connected before the second media segment is the second preset duration, the sum of the first preset duration and the second preset duration is equal to the target transition duration, and the first preset duration is the same as or different from the second preset duration. On this basis, when the duration of the second cropped segment is greater than or equal to the second preset duration, the second newly added segment is composed of part of the media segments in the second cropped segment. At this time, the duration of the media segment cropped from the second media material before the beginning of the second media segment is greater than or equal to the second preset duration, and the media segment can be supplemented before the second media segment by only using the second cropped segment.

[0080] Optionally, the duration of the first newly added segment connected after the first media segment is the first preset duration, the duration of the second newly added segment connected before the second media segment is the second preset duration, the sum of the first preset duration and the second preset duration is equal to the target transition duration, and the first preset duration is the same as or different from the second preset duration. On this basis, when the duration of the second cropped segment is less than the second preset duration, the second newly added segment is composed of all media segments in the second cropped segment and the starting frame in the second cropped segment. At this time, the duration of the media segment cropped from the second media material before the beginning of the second media segment is less than the second preset duration, indicating that it is impossible to complete the media segment before the second media segment using only the second cropped segment, and therefore it is necessary to further supplement it with the help of the starting frame in the second cropped segment.

[0081] Optionally, when the duration of the first cropped segment is zero, the first newly added segment consists only of still frames extracted from the first media segment. The first cropped segment is the media segment cropped after the first media segment when the first media material is cropped to form the first media segment. When the duration of the second cropped segment is zero, the second newly added segment consists only of still frames extracted from the second media material. The duration of the second cropped segment is the media segment cropped before the second media segment when the second media material is cropped to form the second media segment.

[0082] Optionally, the start time TrimIn of the third media segment relative to the first media material and the start time TrimIn of the fourth media segment relative to the second media material are calculated as follows:

[0083] The starting time of the third media segment relative to the first media material, TrimIn: can be calculated directly using source_time_range().start()*speed();

[0084] The fourth media segment is relative to the start point time of the first media material. TrimIn: (1) When the target transition start time between the first media segment and the second media segment is less than the start point time of the second media material, the duration of the second cropped segment cut from the second media material is less than half of the target transition duration, and a still frame is required to supplement it. The third media segment is relative to the start point time of the first media material in the following relationship: D TrimIn =T startTransition -(T startTarget -f(t)T startSource(2) When the target transition start time between the first media segment and the second media segment is greater than or equal to the start time of the second media material, the duration of the second cropped segment cropped from the second media material is greater than or equal to half of the target transition duration, and no still frame supplement is required. The third media segment is expressed in the following relationship relative to the start time of the first media material: D TrimIn =T startTransition -(T startTarget -f(t)T startS . urce ).

[0085] Optionally, the end point time TrimOut of the third media segment relative to the first media material and the end point time TrimOut of the fourth media segment relative to the second media material are calculated as follows:

[0086] The end point time TrimOut of the third media segment relative to the first media material is as follows: TrimOut =f(t)TstartSource+T durationSource +T durationTransiti / 2.

[0087] The end point time TrimOut of the fourth media segment relative to the second media material is as follows: TrimOut =f(t)T startSource +T durationSource

[0088] Among them, the speed change coefficient f(t): when the speed changes in the curve, the f(t) value is the inverse of the speed change value at the critical point with no transition; when the speed changes in the normal way, the f(t) value is the inverse of the speed change value.

[0089] S350: forming a superimposed transition effect at the overlapping portion between the third media segment and the fourth media segment.

[0090] As an optional but non-limiting implementation, generating a target output result based on the third media segment and the fourth media segment includes the following steps A1-A3:

[0091] Step A1: In response to a third operation of triggering speed change configuration for the first media segment in the third media segment on the target editing track, a first curve speed change is added to the first media segment in the third media segment, and an end endpoint speed change corresponding to the first curve speed change is added to the first newly added segment in the third media segment.

[0092] Optionally, the third operation includes a triggering operation of an identifier for performing speed change configuration corresponding to the first media segment in the third media segment on the target editing track, and the identifier for performing speed change configuration corresponding to the first media segment is presented based on the selection operation of the first media segment in the third media segment on the target editing track.

[0093] Referring to FIG. 5 a , the indicator for configuring speed change displayed corresponding to the first media segment is displayed based on the selection of the first media segment 201 in the third media segment on the target editing track, such as the indicator for normal speed change and curved speed change. This triggers the display of the indicator for configuring speed change displayed corresponding to the first media segment 201 in the third media segment on the target editing track.

[0094] Referring to Figure 5b, the first media segment within the third media segment is displayed and a first curve speed change is applied to the first media segment within the third media segment. The first additional segment following the first media segment is then subjected to the same endpoint speed of the first curve speed change used in the first media segment before the transition. The speed change is then applied to the portion of the first additional segment following the first media segment. The first curve speed change is applied to the first media segment, and after trimming or extending it, the first curve speed change is then applied to the first media segment within the third media segment. After the transition is added, an extended portion, a trimmed portion, and a still frame portion are generated. The speed change rate of the first additional segment in the extended portion is the endpoint speed value of the first curve speed change.

[0095] Step A2: In response to the fourth operation of triggering speed change configuration 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 head-end point speed change corresponding to the second curve speed change is added to the second newly added segment in the fourth media segment.

[0096] Optionally, the fourth operation includes a triggering operation of an identifier for performing speed change configuration corresponding to the second media segment in the fourth media segment on the target editing track, and the identifier for performing speed change configuration corresponding to the second media segment is presented based on the selection operation of the second media segment in the fourth media segment on the target editing track.

[0097] Referring to Figure 5b, the second media segment in the fourth media segment is displayed and a second curved speed change is applied to the second media segment. The second curved speed change, which applies to the second media segment before the transition, is applied to the portion of the second media segment before the transition. The second curved speed change is applied to the second media segment, which is then trimmed or extended. The second curved speed change is then applied to the second media segment in the fourth media segment. After the transition is added, the extended portion, trimmed portion, and still frame portion are generated. The speed change rate of the second media segment in the extended portion is the same as the first-end speed of the second curved speed change.

[0098] Step A3: Generate a 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. The target output result is a draft preview before the media segment is exported or a target video after the media segment is exported.

[0099] Optionally, the speed change panel will extend the newly added segment portion in proportion to the corresponding duration. The starting endpoint (left endpoint) of the second newly added segment or the ending endpoint (right endpoint) of the first newly added segment that is connected and extended cannot be adjusted. A speed change point cannot be added between the starting endpoint (left endpoint) of the second newly added segment and the starting endpoint of the second media segment. Adjusting the speed change rate of the starting endpoint of the second media segment can change the speed change rate of the left endpoint of the second newly added segment, and the starting endpoint of the second newly added segment is recalculated according to the new speed change rate; a speed change point cannot be added between the ending endpoint (right endpoint) of the first newly added segment and the ending point of the first media segment. Adjusting the speed change of the ending endpoint of the first media segment can change the speed change rate of the right endpoint of the first newly added segment, and the ending endpoint of the first newly added segment is recalculated according to the new rate.

[0100] As an optional but non-limiting implementation method, 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, it also includes: performing chroma keying, destrobing, noise reduction, anti-shake processing, and motion tracking on the first newly added segment and the second newly added segment.

[0101] The technical solution of the embodiment of the present disclosure creates a target transition task for transition editing of media segments, and forms a corresponding third media segment by adding a first newly added segment at the end of the adjacent and end-connected first media segment and forms a corresponding fourth media segment by adding a second newly added segment at the beginning of the second media segment, so that part of the picture at the end of the third media segment corresponding to the first media segment and part of the picture at the beginning of the fourth media segment corresponding to the second media segment can be superimposed together, so that when the picture of the previous media segment gradually fades away, the picture of the next media segment gradually appears and is clearly superimposed on the transition effect. At the same time, since the positions of the first media segment and the second media segment in the target editing track remain unchanged, the total duration of the two adjacent media segments after the superimposed transition effect can be maintained unchanged.
