[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0030] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0031] Currently, the multiple editing tracks in the video editing interface have different corresponding rendering levels. By adjusting the rendering level of the editing track, you can adjust the display priority of the video material, thereby improving the rendering effect of the video.

[0032] In the prior art, multiple editing tracks in a video editing interface may include video tracks, text tracks, sticker tracks, etc. Among them, the video track has the highest rendering level, that is, the video material is rendered first, and then the text material, sticker material, etc. are rendered. However, since the video track has the highest rendering level, the text material, sticker material, etc. can only be displayed on top of the video material, resulting in a low degree of freedom in rendering multiple editing materials, which in turn affects the user experience.

[0033] It can be seen that how to improve the rendering freedom of editing materials to improve user experience is an urgent problem to be solved.

[0034] In order to solve the above problems, the present embodiment provides the following technical concepts: first, in response to receiving the order adjustment operation of the editing track where the editing material is located, the preview position of the video editing effect is obtained, and multiple editing materials corresponding to the preview position are determined, wherein the multiple editing materials are respectively located on multiple different editing tracks in the video editing interface; then, according to the arrangement order of the multiple different editing tracks, the rendering level corresponding to each of the multiple editing materials is determined, wherein the rendering level is used to indicate the rendering priority of the editing material; finally, according to the rendering level corresponding to each of the multiple editing materials, the multiple editing materials are rendered to obtain the video editing effect at the preview position. That is, according to the arrangement order of the multiple different editing tracks, the rendering level corresponding to each of the multiple editing materials is determined, and the rendering levels of the multiple editing tracks can be adjusted at will, so that text materials, sticker materials, etc. can be displayed above or below the video materials, thereby improving the rendering freedom of the editing materials and thus improving the user experience.

[0035] The application scenario of the embodiment of the present disclosure is explained below: the video rendering method provided by the embodiment of the present disclosure can be applied to the scenario of adjusting the rendering level of the editing material. Figure 1 Schematic diagram of a video editing interface provided by an embodiment of the present disclosure. Figure 1 As shown, the video editing interface includes multiple editing materials, namely video clip 1, video clip 2 and text 1. In the present application, the track types of video clip 1, video clip 2 and text 1 are all the same preset track type, so that text 1 can be moved to the bottom of video clip 2, and then the rendering level of text 1 and video clip 2 can be adjusted. That is, text 1 can be displayed above video clip 2 or below video clip 2. The video rendering method provided by the embodiment of the present disclosure is described in detail using a detailed embodiment below.

[0036] Figure 2 The flowchart of a video rendering method provided by the embodiment of the present disclosure is shown in FIG. The execution subject of the method can be a terminal or a server. The embodiment of the present disclosure is described by taking the execution subject as a terminal as an example. Figure 2 As shown, the method includes:

[0037] S201. In response to receiving a sequence adjustment operation of an editing track where an editing material is located, obtaining a preview position of a video editing effect, and determining a plurality of editing materials corresponding to the preview position, wherein the plurality of editing materials are respectively located on a plurality of different editing tracks in a video editing interface.

[0038] In the embodiment of the present disclosure, the sequence adjustment operation may be any operation related to the editing track sequence. Optionally, the sequence adjustment operation may include an editing track position adjustment operation and / or an editing track addition operation.

[0039] In the disclosed embodiment, one editing material corresponds to one playback time period. If the preview position of the video editing effect is within the playback time period of the editing material, then the editing material is the editing material corresponding to the preview position. Accordingly, this step is: obtaining multiple candidate editing materials in the video editing interface, for each candidate editing material, if the preview position is within the playback time period of the candidate editing material, then determining that the candidate editing material is the editing material corresponding to the preview position.

[0040] Optionally, multiple candidate editing materials in the video editing interface can be obtained through the material identifier of the editing material. It should be noted that the multiple editing materials do not include audio materials. Accordingly, before obtaining multiple candidate editing materials, the material identifier corresponding to the audio material can be modified to other identifiers. Optionally, the other identifier is a filter identifier. Exemplarily, the material identifier can be represented by clipID, and the filter identifier can be represented by filterID, that is, the clipID corresponding to the audio material is modified to filterID. In this way, it is possible to avoid obtaining the audio material in the video editing interface.

[0041] S202 . Determine rendering levels corresponding to each of the multiple editing materials according to the arrangement order of the multiple different editing tracks, wherein the rendering level is used to indicate a rendering priority of the editing material.

[0042] In the disclosed embodiment, this step may include: according to the arrangement order of multiple different editing tracks, determining the serial number of each editing track in the arrangement order; determining the serial number of the editing track in the arrangement order as the rendering level of the editing material on the editing track, and obtaining the rendering level corresponding to each of the multiple editing materials. Optionally, the serial number of the editing track in the arrangement order can be represented by trackindex, and the rendering level of the editing material can be represented by track_render_index.

[0043] For example, Figure 3 As shown, the multiple editing materials include: video clip 1, video clip 2 and text 1. In the traditional mode, the rendering level of each editing material is determined by setting the rendering level parameter (renderIndex). The rendering level parameter of video clip 1 is set to 1001, the rendering level parameter of video clip 2 is set to 1002, and the rendering level parameter of text 1 is set to 1003. In this way, text 1 is located above video clip 2, and video clip 2 is located above video clip 1.

[0044] In free level mode, the sequence number of the editing track in the arrangement order is determined as the rendering level of the editing material on the editing track. Figure 3 As shown in FIG. 1 , in the arrangement order of the editing tracks, the numbers of video clip 1, video clip 2, and text 1 are 1, 2, and 3, respectively. Accordingly, the rendering level of video clip 1 is 1 ( Figure 3 Track_render_Index=1), the rendering level of video clip 2 is 2 ( Figure 3 Track_render_Index=2), the rendering level of text 1 is 3 ( Figure 3 Track_render_Index=3).

[0045] It should be noted that the current video rendering mode is the free-level mode, which first converts the track types of multiple different editing tracks to the same preset track type. In this way, the arrangement order of the editing tracks can be freely adjusted.

[0046] In the disclosed embodiment, the preset track type may be a video track. Exemplarily, the multiple editing materials include: video clip 1, special effect 1 and text 1. Then the track types of video clip 1, special effect 1 and text 1 are all set to video track. Exemplarily, the special effect track can be represented by EffectTrack, and the video track can be represented by VideoTrack. At this time, the track type EffectTrack of special effect 1 is converted to VideoTrack.

[0047] In an embodiment of the present disclosure, the user can also switch the video rendering mode through a switching operation. The video rendering mode includes a free hierarchy mode and a non-free hierarchy mode. Exemplarily, the switching operation may be a click operation on a switch button corresponding to the free hierarchy. Optionally, in response to receiving a switching operation of the video rendering mode, the mode interface information corresponding to the video rendering mode is obtained; if the mode interface information is a first interface identifier, the video rendering mode is determined to be a free hierarchy mode; if the mode interface information is a second interface identifier, the video rendering mode is determined to be a non-free hierarchy mode.

[0048] Exemplarily, the mode interface information is: render_index_track_mode_on interface. The first interface identifier is true, and the second interface identifier is false. If the mode interface information corresponding to the render_index_track_mode_on interface is true, the video rendering mode is determined to be the free layer mode. If the mode interface information corresponding to the render_index_track_mode_on interface is false, the video rendering mode is determined to be the non-free layer mode.

[0049] S203 , rendering the multiple editing materials according to the rendering levels corresponding to the multiple editing materials respectively, to obtain the video editing effect at the preview position.

[0050] Optionally, according to the rendering levels corresponding to the multiple editing materials respectively, the multiple editing materials are rendered in sequence in an ascending order of the rendering levels to obtain a video editing effect at a preview position.

[0051] For example, Figure 3 As shown, in the order of rendering level from small to large, video clip 1, video clip 2, and text 1 are rendered in sequence. Among them, the edited material rendered later is located above the edited material rendered earlier. That is, text 1 is located above video clip 2, and video clip 2 is located above video clip 1.

[0052] The disclosed embodiment provides a video rendering method: in response to receiving a sequence adjustment operation of an editing track where an editing material is located, obtaining a preview position of a video editing effect, and determining a plurality of editing materials corresponding to the preview position, wherein the plurality of editing materials are respectively located on a plurality of different editing tracks in a video editing interface; determining a rendering level corresponding to each of the plurality of editing materials according to an arrangement order of the plurality of different editing tracks, wherein the rendering level is used to indicate a rendering priority of the editing material; rendering the plurality of editing materials according to the rendering level corresponding to each of the plurality of editing materials to obtain a video editing effect at the preview position. In the disclosed embodiment, since the rendering level corresponding to each of the plurality of editing materials is determined according to an arrangement order of the plurality of different editing tracks, the rendering levels of the plurality of editing tracks can be adjusted at will, so that text materials, sticker materials, etc. can be displayed above or below the video material, thereby improving the rendering freedom of the editing material and thus improving the user experience.

[0053] It should be noted that the user can also adjust the rendering effect of the material. In this case, the video editing interface can also include an adjustment track for adjusting the rendering effect. The adjustment track can adjust the rendering effect of the editing material. Figure 4 As shown, the method also includes:

[0054] S401: Determine the rendering level corresponding to the adjustment track.

[0055] In an embodiment of the present disclosure, the adjustment track may include a plurality of rendering adjustment parameters. Optionally, the rendering adjustment parameters include one or more of color temperature, hue, saturation, brightness, contrast, shadows, and highlights.

[0056] In this case, the rendering level corresponding to the adjustment track includes sub-rendering levels corresponding to multiple rendering adjustment parameters. In order to solve the problem that one adjustment track corresponds to multiple sub-rendering levels, the rendering level corresponding to the adjustment track can be enlarged. Accordingly, this step is: for each adjustment track, determine the track level of the adjustment track, and determine the track level of the adjustment track as the rendering level corresponding to the adjustment track; according to the number of multiple rendering adjustment parameters included in the adjustment track, enlarge the rendering level of the adjustment track to obtain a number of sub-rendering levels, wherein the end serial numbers of the multiple sub-rendering levels are different; and determine the sub-rendering levels corresponding to the multiple rendering adjustment parameters in order from small to large according to the end serial numbers of the multiple sub-rendering levels.

[0057] Exemplarily, the magnification of the enlargement process is 100 times. The number of rendering adjustment parameters includes color temperature, hue, saturation, brightness, contrast, shadow and highlight. At this time, the number of rendering adjustment parameters is 7. The rendering level corresponding to the adjustment track is 2. The rendering level of the adjustment track is enlarged to obtain 7 sub-rendering levels, namely: 201, 202, 203, 204, 205, 206 and 207, wherein the end serial numbers of the multiple sub-rendering levels are different. According to the order of the end serial numbers from small to large, it is determined that the sub-rendering level corresponding to the color temperature is 201, the sub-rendering level corresponding to the hue is 202, the sub-rendering level corresponding to the saturation is 203, the sub-rendering level corresponding to the brightness is 204, the sub-rendering level corresponding to the contrast is 205, the sub-rendering level corresponding to the shadow is 206, and the sub-rendering level corresponding to the highlight is 207.

[0058] S402 . According to the rendering level corresponding to the adjustment track and the rendering levels corresponding to the plurality of editing materials, select at least one target editing material having a rendering level smaller than the rendering level corresponding to the adjustment track from the plurality of editing materials.

[0059] Exemplarily, the multiple editing materials include video clip 1, video clip 2, and text 1. The rendering levels corresponding to video clip 1, video clip 2, and text 1 are 1, 3, and 4, respectively. The rendering level corresponding to the adjustment track is 2, and the target editing material with a rendering level less than 2 selected from the multiple editing materials is: video clip 1.

[0060] It should be noted that for multiple sub-rendering levels, by judging the size of the rendering level of the editing material and the first digit of the sub-rendering level, it is determined whether the editing material is the target editing material. For example, the sub-rendering level corresponding to the color temperature is 201, and the first digit is 2. In this case, the rendering level 1 of the video clip 1 is less than 2, then the video clip 1 is the target editing material. The rendering level 1 of the video clip 2 and the text 1 are 3 and 4 respectively, both greater than 2, then the video clip 2 and the text 1 are not the target editing material.

[0061] S403: Adjust the rendering effect of at least one target editing material by adjusting the track.

[0062] Optionally, this step is: adjusting a rendering effect of at least one target editing material by adjusting a plurality of rendering adjustment parameters included in the track.

[0063] Here, if the rendering level is not enlarged, multiple rendering adjustment parameters cannot be inserted between rendering level 2 and rendering level 3. However, the present application sets multiple sub-rendering levels to adjust the rendering effect of the target editing material through multiple rendering adjustment parameters, thereby further improving the rendering freedom of the editing material.

[0064] It should be noted that in free level mode, the track types of multiple editing tracks are the same. In order to avoid confusion between different types of editing materials during transition, it is necessary to determine two editing materials to be transitioned. Accordingly, the method may also include: in response to receiving a transition operation of the editing material, determining a first material identifier of the first editing material before the transition and a second material identifier of the second editing material after the transition; and transitioning the first editing material to the second editing material according to the first material identifier and the second material identifier.

[0065] The material identifier is used to distinguish different editing materials. Optionally, the material identifier includes the material type and the material serial number. For example, the material identifier may be video material 1, video material 2, or text 1.

[0066] Another point to be explained is that if multiple sub-editing materials are displayed on the editing track, the positions of the sub-editing materials can be swapped through the temporary editing track. Accordingly, the method further includes: in response to receiving a position swap operation for the first sub-editing material and the second sub-editing material, creating a temporary editing track; transferring the second sub-editing material to the temporary editing track, adjusting the position of the first sub-editing material to the position of the second sub-editing material; and transferring the second sub-editing material from the temporary editing track to the position of the first sub-editing material.

[0067] For example, Figure 5 As shown in the figure, there are multiple sub-editing materials displayed on the editing track: Material A, Material B and Material C. When the positions of Material A and Material B are swapped, Material A can be transferred to the temporary editing track, and then the position of Material B can be adjusted to the position of Material A, and then Material A can be transferred from the temporary editing track to the position of Material B.

[0068] Here, since the track level of the editing material is consistent with the rendering level of the editing material, the rendering levels of multiple sub-editing materials on the same editing track are the same. In this case, if the positions of the sub-editing materials are swapped, the change of the rendering level can be avoided by creating a temporary editing track, thereby further improving the rendering freedom of the editing material.

[0069] Another point to be explained is that in the free level mode, when exporting a video through multiple editing materials, the playback time of the exported video is determined by the editing material with the longest playback time. Accordingly, the method further includes: in response to the video export operation, determining the playback time corresponding to each editing material; and determining the longest playback time as the playback time of the exported video corresponding to the multiple editing materials.

[0070] Exemplarily, the multiple editing materials include video clip 1, video clip 2, and text 1. Among them, the playback time of video clip 1 is 2 minutes, the playback time of video clip 2 is 1 minute, and the playback time of text 1 is 30 seconds, then the maximum playback time (2 minutes) is determined as the playback time of the exported video corresponding to the multiple editing materials.

[0071] In the disclosed embodiment, if the video rendering mode is the free-level mode, the time interface of the non-free-level mode needs to be discarded. Optionally, the time interface of the non-free-level mode includes: a set duration interface (setDuration interface) and a get duration interface (getDuration interface). That is, the setDuration interface and the getDuration interface need to be discarded.
