The inventors have discovered that manually adjusting and cropping multimedia materials by users is difficult to quickly and accurately adjust to the same length. In light of this, a technical problem addressed by this disclosure is how to more efficiently and accurately adjust the multimedia materials to be synthesized. This disclosure provides a method for editing multimedia materials, which is described below in conjunction with Figures 1 to 8. Figure 1 is a flowchart of some embodiments of the method for editing multimedia materials disclosed herein. As shown in FIG1 , the method of this embodiment includes steps S102 to S106. In step S102, information of the first multimedia material is displayed in the first track according to the duration of the first multimedia material, and information of the second multimedia material is displayed in the second track according to the duration of the second multimedia material.Before step S102, the process may also include receiving a user trigger operation on the editing interface. In some embodiments, the trigger operation on the editing interface is to display the editing interface after adding a second multimedia material for synthesis to the first multimedia material, or to display the editing interface after adding a first multimedia material for synthesis to the second multimedia material, or to display the editing interface after adding multiple multimedia materials, without limitation to the examples. For example, upon receiving a user selection of a first multimedia material for editing, information about the first multimedia material is displayed in the first track of the editing interface according to the duration of the first multimedia material; upon receiving a user addition operation, candidate multimedia materials are displayed or a search interface is displayed; upon receiving a user confirmation operation on the second multimedia material, the editing interface is displayed. For another example, upon receiving a user selection of the first multimedia material and the second multimedia material from the candidate multimedia materials, a prompt indicating that the first multimedia material and the second multimedia material have been selected is displayed; upon receiving a user trigger operation on the editing function, the editing interface is displayed. In the present disclosure, user operations can be implemented through various means, such as clicking controls or voice commands, and are not limited here. For example, as shown in Figure 2, the starting ends of the first and second tracks are aligned and displayed in a parallel arrangement. The vertical position of the first and second tracks is not restricted. The information of the first multimedia material in the first track and the information of the second multimedia material in the second track can be displayed in full or with a sliding display. For example, if the information of the first or second multimedia material exceeds a preset length, a portion of the preset length is displayed, and the remaining portion can be displayed by sliding. For example, a user can swipe left or right to display the undisplayed portion and change the starting time of playback of the first multimedia material. First and second multimedia materials of the same length have the same display length. One or more time markers can also be displayed corresponding to the first and / or second tracks. The time markers can indicate the duration of a partial segment of the first or second multimedia material or its entire duration. As shown in Figure 2, the editing interface can also include a preview area for the synthesized multimedia material and a playback control. Upon triggering the playback control by the user, the synthesized multimedia material can be played in the preview area. As shown in FIG2 , the editing interface may also display an add control for adding multimedia material. Upon receiving a user trigger operation on the add control, information about the third multimedia material is displayed in the third track according to the duration of the third multimedia material. Multimedia materials may also be added in other ways, not limited to the examples shown. As shown in FIG2 , the editing interface may also display at least one of a replace control, a delete control, and a volume control.The Replace control can be used to replace an added multimedia material. Upon receiving a user trigger on the Replace control, candidate multimedia materials are displayed. Upon receiving a user selection of any multimedia material, the Replace control can be used to replace the added multimedia material. For example, if a first multimedia material is added to a second multimedia material, the Replace control can be used to replace the first multimedia material. The Delete control can be used to delete an added multimedia material. Upon receiving a user trigger on the Delete control, the added multimedia material and the corresponding track are deleted. The Delete control can also be used to delete multiple multimedia materials simultaneously. The Volume control can be used to adjust the volume of the added multimedia material, the first multimedia material, the second multimedia material, or the synthesized multimedia material. The editing interface may also include a Speed ​​Adjustment control to adjust the speed of the added multimedia material, the first multimedia material, the second multimedia material, or the synthesized multimedia material. The functions of these controls can be replaced by other means, for example, through voice commands or by double-clicking, pressing, or other operations to adjust volume or speed, without limiting the examples. In some embodiments, the first multimedia material and the second multimedia material are the multimedia materials to be synthesized. The first multimedia material is a video, audio, image, or special effects material, and the second multimedia material is a video, audio, image, or special effects material. Special effects materials include, for example, subtitles, special effects, text, stickers, and the like, without limiting the examples. Synthesis and editing can be performed on multiple multimedia materials of any type. In some embodiments, information about the first multimedia material includes: at least one of one or more images or text corresponding to the first multimedia material; information about the second multimedia material includes: at least one of one or more images or text corresponding to the second multimedia material. For example, if the first multimedia material is audio, the information about the first multimedia material displayed in the first track includes at least one of a waveform image and a name text. For another example, when the second multimedia material is a video, the information of the second multimedia material displayed in the second track is multiple frames of images. The multiple frames of images can be thumbnails of multiple frames of images extracted from the video according to a preset sampling interval, for example, one frame of image is extracted every 0.1 second.The first length of the information of the first multimedia material displayed in the first track is proportional to the first duration of the first multimedia material; the second length of the information of the second multimedia material displayed in the second track is proportional to the second duration of the second multimedia material, and the ratio of the first length to the first duration and the ratio of the second length to the second duration are equal. In step S104, a user trigger operation is received. For example, the trigger operation is used to trigger the automatic selection of the information of the first multimedia material. As shown in Figure 2, an adjustment control can be provided to receive a user trigger operation on the adjustment control. Alternatively, a user selection operation of the first multimedia material and a trigger operation on the adjustment control can be received. Alternatively, an operation such as clicking or double-clicking the first track or the second track can be used as a trigger operation. The specific form of the trigger operation is not limited. In step S106, a first selection area for automatically selecting the information of the first multimedia material is displayed in the first track. The range of the first selection area is aligned with the display range of the information of the second multimedia material, and the duration of the segment of the first multimedia material corresponding to the range of the first selection area is equal to the duration of the second multimedia material. Aligning the two ranges means that the two ranges are of the same length and are displayed in correspondence. Step S104 is optional. After receiving a user trigger operation on the editing interface, information about the first multimedia material may be displayed in the first track according to the duration of the first multimedia material, and information about the second multimedia material may be displayed in the second track according to the duration of the second multimedia material. Furthermore, a first selection area automatically selected for the information about the first multimedia material is displayed in the first track. The duration of the first multimedia material is greater than or equal to the duration of the second multimedia material, meaning that the display range of the first multimedia material information is greater than or equal to the display range of the second multimedia material information. The range of the first selection area is aligned with the display range of the second multimedia material information, and the duration of the segment of the first multimedia material corresponding to the range of the first selection area is equal to the duration of the second multimedia material. Within the first track, the display range of the first multimedia material information that is aligned with the display range of the second multimedia material information is automatically selected as the first selection area. In some embodiments, it is determined whether the first multimedia material has been cropped; if the first multimedia material has not been cropped, the starting point of the first multimedia material is used as the starting point of the first selection area, and the ending point of the first selection area is determined based on the ending point of the second multimedia material information; if the first multimedia material has been cropped, the starting point of the cropped first multimedia material is used as the starting point of the first selection area, and the ending point of the first selection area is determined based on the starting point of the first selection area and the duration of the second multimedia material; and the first selection area is displayed based on the starting point and ending point of the first selection area.Whether the first multimedia material is cropped can be determined based on a record of whether the first selection area has been adjusted or based on a user's cropping operation record. In some embodiments, the portion of the first multimedia material within the first selection area and the portion of the first multimedia material outside the first selection area are displayed with different display effects. For example, different transparency or color masks can be used within and outside the first selection area. In another example, the first selection area can be displayed in the form of a window or selection box. As shown in Figure 3, taking the first multimedia material as audio and the second multimedia material as video as an example, if the audio duration is greater than the video duration, the first selection area is displayed in the first track, and the range of the first selection area is aligned with the display range of the video image. The first selection area and the second multimedia material can be fully displayed in the interface for easy user viewing. The information of the first multimedia material outside the first selection area can be partially displayed, and the information displayed in the first track can be adjusted as a whole through a sliding operation. Figures 2 and 3 can represent the same interface or different interfaces, without limitation. The subsequent embodiments use the editing interface for description, but those skilled in the art will understand that the first editing interface can be displayed before the triggering operation and the second editing interface can be displayed after the triggering operation. In some embodiments, a second selection area for selecting information about a second multimedia material is displayed in the second track, where the range of the first selection area is aligned with the range of the second selection area. The second selection area can be selected based on a user's operation or automatically. If the second selection area is displayed in the second track, the range of the first selection area is aligned with the range of the second selection area. If the second selection area is not displayed in the second track, the range of the first selection area is aligned with the display range of the second multimedia material's information. The range of the second selection area can include the entire display range of the second multimedia material's information or a portion of the display range. As shown in FIG. 4 , the range of the second selection area covers the entire display range of the second multimedia material's information. As shown in FIG. 5 , the range of the second selection area covers a portion of the display range of the second multimedia material's information. In some embodiments, if the duration of the first multimedia material is equal to that of the second multimedia material, the second selection area is not displayed in the second track; if the duration of the first multimedia material is greater than that of the second multimedia material, the second selection area is displayed in the second track; and if the duration of the first multimedia material is less than that of the second multimedia material, the second selection area is displayed in the second track. When the duration of the first multimedia material is shorter than that of the second multimedia material, the first selection area may not be displayed and only the second selection area may be displayed, or both the first selection area and the second selection area may be displayed simultaneously.The range of the first selection area is aligned with the range of the second selection area. The range of the first selection area can include the entire display range or a portion of the display range of the first multimedia material's information. For shorter multimedia materials, they can be fully displayed in the corresponding track for easier user viewing. In the above embodiment, there can be one or more first multimedia materials, and each first multimedia material can display a corresponding first selection area. This will not be described in detail here. In the method of the above embodiment, the first multimedia material's information is displayed in the first track, and the second multimedia material's information is displayed in the second track. The first and second multimedia material's information are displayed in time correspondence. Upon receiving a user trigger operation, the automatic selection of the first multimedia material's information is triggered, and the first selection area automatically selected for the first multimedia material's information is displayed in the first track. The first selection area is aligned with the display range of the second multimedia material's information. The method of the above embodiment automatically selects and displays a first selection area of ​​equal length to the shorter second multimedia material within the longer first multimedia material, and aligns it with the display range of the second multimedia material's information. Manual adjustment of the first multimedia material by the user is unnecessary, and the lengths of multiple multimedia materials can be quickly and accurately aligned, improving the efficiency and accuracy of adjusting the multimedia materials to be synthesized. The following describes further embodiments of the multimedia material editing method disclosed herein in conjunction with FIG6 . FIG6 is a flow chart of further embodiments of the multimedia material editing method disclosed herein. As shown in FIG6 , the method of this embodiment includes steps S602 to S606. In step S602, a first user adjustment operation on the range of a first selection area is received. For example, the user adjustment operation on the edge of the first selection area is received. As shown in FIG4 and FIG5 , edge controls can be provided on the edge of the first selection area, and the range of the first selection area can be adjusted by operating the edge controls; alternatively, the range of the first selection area can be adjusted by sliding the window or selection box corresponding to the first selection area. Adjusting the range of the first selection area indicates that the start and / or end positions of the segments of the first multimedia material selected for synthesis are adjusted. In some embodiments, in response to the user adjusting the edge of the first selection area to the edge of the information of the first multimedia material, a first prompt message is issued, wherein the first prompt message is used to prompt that the edge of the first selection area cannot exceed the edge of the information of the first multimedia material; and / or in response to the user adjusting the range of the first selection area to a first minimum range, a second prompt message is issued, wherein the second prompt message is used to prompt that the range of the first selection area cannot be reduced any further.The first and second prompt information can be in the form of text, sound, image, or vibration, and are not limited to the examples given. The maximum range of the first selection area is the complete display range of the first multimedia material information. The minimum range of the first selection area can be preset, for example, to a display range corresponding to 0.1 seconds. In step S604, a second user adjustment operation on the range of the second selection area is received. For example, the second user adjustment operation on the edge of the second selection area is received. For example, an edge control can be provided on the edge of the second selection area, and the range of the first selection area can be adjusted by operating the edge control; or the range of the second selection area can be adjusted by sliding the window or selection box corresponding to the second selection area. The adjustment of the range of the second selection area indicates that the start position and / or end position of the segment of the second multimedia material selected for synthesis has been adjusted. In some embodiments, in response to the user adjusting the edge of the second selection area to the edge of the second multimedia material, a third prompt message is issued, wherein the third prompt message indicates that the edge of the second selection area cannot extend beyond the edge of the second multimedia material. In response to the user adjusting the range of the second selection area to the second minimum range, a fourth prompt message is issued, wherein the fourth prompt message indicates that the range of the second selection area cannot be further reduced. The third and fourth prompt messages can be in the form of text, sound, image, or vibration, and are not limited to the examples given. The maximum range of the second selection area is the complete display range of the second multimedia material information, and the minimum range of the second selection area can be preset. The ranges of the first and second selection areas can be adjusted differently. For example, the edge of the first selection area can be provided with an edge control, while the corresponding window or selection box of the second selection area supports sliding operations, and are not limited to the examples given. The first and second selection areas can be automatically adjusted together. During the adjustment process, the first and second selection areas do not exceed their respective maximum and minimum ranges. In step S606, the dynamically adjusted first selection area is displayed in the first track, and the dynamically adjusted second selection area is displayed in the second track. For example, when a user performs a first adjustment operation on the range of a first selection area, the adjusted first selection area is dynamically displayed in the first track following the first adjustment operation, and the second selection area dynamically adjusted along with the first selection area is displayed in the second track. When a user performs a second adjustment operation on the range of a second selection area, the adjusted second selection area is dynamically displayed in the second track following the second adjustment operation, and the first selection area dynamically adjusted along with the second selection area is displayed in the first track.The range of the first selection area is dynamically aligned with the range of the second selection area. The first and second selection areas can be dynamically adjusted and displayed together. Adjusting one area automatically adjusts the other area, maintaining alignment. The method of the above embodiment dynamically adjusts both areas by adjusting either the first or second selection area, improving the efficiency and accuracy of adjusting the multimedia material to be synthesized. In some embodiments, a user movement operation is received to move information of a first multimedia material in a first track relative to the first selection area; the information of the first multimedia material moved relative to the first selection area is dynamically displayed in the first track, wherein the position of the first selection area relative to the first track remains unchanged. For example, if a sliding operation is performed on the information of the first multimedia material in the first track, while the position of the first selection area relative to the first track remains unchanged, the corresponding segment of the first multimedia material in the first selection area will change, i.e., the selected segment of the first multimedia material will change. If the position of the first selection area relative to the first track remains unchanged, the position of the second selection area will also remain unchanged. In this way, only the segment of the first multimedia material corresponding to the first selection area is changed, while the segment of the second multimedia material corresponding to the second selection area remains unchanged. In some embodiments, a user movement operation is received on information of a second multimedia material in a second track relative to a second selection area; the information of the second multimedia material moved relative to the second selection area is dynamically displayed in the second track, wherein the position of the second selection area relative to the second track remains unchanged. For example, if a sliding operation is performed on the information of the second multimedia material in the second track while the position of the second selection area relative to the second track remains unchanged, the corresponding segment of the second multimedia material within the second selection area will change, i.e., the selected segment of the second multimedia material will change. By adjusting the range of the first selection area or the second selection area, and moving the information of the first multimedia material in the first track or the second multimedia material in the second track, any segment of the first multimedia material can be combined and synthesized with any segment of the second multimedia material, thereby improving the flexibility of multimedia material synthesis and the efficiency and accuracy of adjusting the multimedia materials to be synthesized. Further embodiments of the multimedia material editing method disclosed herein are described below with reference to FIG. FIG. 7 is a flowchart of further embodiments of the multimedia material editing method disclosed herein. As shown in FIG. 7 , the method of this embodiment includes steps S702 to S710. In step S702, a user triggering operation for a preview function is received. As shown in FIG8 , the user can trigger the preview function by clicking a play control, speaking, or other operations.In step S704, a multimedia material composed of the first segment of the first multimedia material corresponding to the first selected area and the second segment of the second multimedia material corresponding to the second selected area is played. In some embodiments, if the second selected area is not displayed, meaning that the entire second multimedia material is used for the composition, a user triggering the play function is received; the multimedia material composed of the first segment of the first multimedia material corresponding to the first selected area and the second multimedia material is played. The composed multimedia material can be played in a loop. As shown in FIG8 , the editing interface can also display a preview area in which the composed multimedia material can be played. Alternatively, the composed multimedia material can be played in a new window, without being limited to this example. In step S706, the playback progress of the first segment is dynamically displayed in the first track, and the playback progress of the second segment is dynamically displayed in the second track. Steps S704 and S706 can be performed in parallel. For example, the playback progress can be displayed using animation or an indicator. For example, as shown in FIG8 , if the first multimedia material is audio and the second multimedia material is video, the playback progress can be displayed in the first track using a waveform animation, while the playback progress can be indicated by a moving indicator line in the second track. In step S708, during playback, a user adjustment operation is received for the range of the first or second selection area. The adjustment operation for the range of the first or second selection area can be referred to in the previous embodiment and will not be further described here. In step S710, playback is paused, and the dynamically adjusted first selection area is displayed in the first track, and the dynamically adjusted second selection area is displayed in the second track. The range of the second selection area is dynamically aligned with the range of the first selection area. In some embodiments, during playback, a user movement operation is received for the first multimedia material in the first track, and playback is paused. The dynamically moved information of the first multimedia material may be further displayed in the first track. The position of the first selection area relative to the first track remains unchanged. During playback, a user movement operation is received for the second multimedia material in the second track, and playback is paused. The dynamically moved information of the second multimedia material may be further displayed in the second track. In some embodiments, a user triggering operation to adjust the playback speed is received, and the synthesized multimedia material is played at the adjusted speed. In some embodiments, a user trigger operation for a pause function is received, playback is paused, and the playback position of the first segment at the time of the pause is dynamically displayed in the first track, and the playback position of the second segment at the time of the pause is dynamically displayed in the second track.The method of the above embodiment allows users to view the effect of the synthesized multimedia material at any time and flexibly select segments from the first and second multimedia materials, improving selection efficiency and accuracy. In some embodiments, a user triggers a save function; a multimedia material synthesized by the segments of the first and second multimedia materials corresponding to the first selection area is saved and displayed. When the second selection area is displayed, the segments of the second multimedia material corresponding to the first selection area are the segments of the second multimedia material corresponding to the second selection area. When the second selection area is not displayed, the segments of the second multimedia material corresponding to the first selection area are the complete second multimedia material. For example, in a scenario where the first multimedia material is added to the second multimedia material for synthesis, the second multimedia material can be played in the original playback interface before the addition operation. After the save operation, the original playback interface can be exited to return to the original playback interface to display the synthesized multimedia material. If the synthesized multimedia material has been previewed and played in the editing interface, the current playback position is recorded, and playback can be resumed based on the current playback position after returning to the original playback interface. Since a portion of the synthesized multimedia material has already been previewed, returning to the original playback interface to play the remaining playback can improve efficiency and enhance the user experience. The original playback position of the second multimedia material in the original playback interface can be recorded, and playback can resume from the original playback position after returning to the original playback interface. In some embodiments, a user trigger operation to cancel the function is received; the synthesized multimedia material is deleted. For example, in a scenario where a first multimedia material is added to a second multimedia material for synthesis, the second multimedia material can be played in the original playback interface before the addition operation. After the operation is canceled, the original playback interface can be returned to after exiting the editing interface.
