It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

FIG. 1 is a diagram of an exemplary video processing system. Referring to fig. 1, the video method is applied to a video processing system. The video processing system includes aterminal 110 and aserver 120. Theterminal 110 and theserver 120 are connected through a network. Theterminal 110 may specifically be a desktop terminal or a mobile terminal, and the mobile terminal may specifically be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. Theserver 120 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers.

In an embodiment, an application (or a client) supporting a video processing function implemented by a video processing method may be installed and run on theterminal 110, where the application may be a video editing application for editing videos, and during a process of editing a video sequence by a user, theterminal 110 may add a plurality of video special effects to the video sequence by using the video processing method. The application program may also be a video generation application program, and a user may record a video, share a video, and the like through the video generation application program, and the user may also add a video special effect to the video, and theterminal 110 may add a plurality of video special effects to the video sequence through the video processing method.

In one embodiment, theterminal 110 may obtain a video sequence to be processed; acquiring at least two video effects to be added to a video sequence; constructing a special effect object of a video sequence according to the time range of adding each video special effect; after sequencing all the special effect objects, obtaining the special effect objects in sequence; and adding the first special effect object to the video sequence to generate a new video sequence, repeating the step of adding the next special effect object to the video sequence generated last time to generate a new video sequence, and obtaining the target video sequence after adding the last special effect object to the video sequence generated last time.

In other embodiments, theterminal 110 may also obtain a video sequence to be processed; acquiring at least two video effects to be added to a video sequence; sending the video sequence to be processed and the at least two video effects to be added to the video sequence to theserver 120 through the network; theserver 120 constructs a special effect object of the video sequence according to the time range of adding each video special effect; after sequencing all the special effect objects, obtaining the special effect objects in sequence; a new video sequence is generated after the first special effect object is added to the video sequence, the step of generating a new video sequence after the next special effect object is added to the video sequence generated last time is repeated until a target video sequence is obtained after the last special effect object is added to the video sequence generated last time, and the obtained target video sequence is returned to theterminal 110.

In some embodiments, theterminal 110 may further display the target video to which the plurality of video effects are added after the plurality of video effects are added to the video sequence, and the user may preview the video effect to which the plurality of video effects are added in real time. In other embodiments, theterminal 110 may further obtain a video export operation triggered by the user before obtaining the target video sequence, and perform a complete video encoding and decoding process on the finally generated new video sequence according to the video export operation, so as to obtain video data of the target video sequence.

In one embodiment, as shown in FIG. 2, a video processing method is provided. The present embodiment exemplifies the application of the video processing method to the terminal 110 in fig. 1 described above. Referring to fig. 2, the video processing method specifically includes the following steps S202 to S210:

s202, a video sequence to be processed is obtained.

The video sequence is video data formed by a plurality of video clips which are arranged in sequence, and the video sequence to be processed is a video sequence to which a plurality of video special effects are added. The plurality of video segments are greater than or equal to two video segments. The terminal can obtain a plurality of video clips selected by a user, and a video sequence formed by the selected video clips in sequence is used as a video sequence to be processed according to the sequence of the video clips selected by the user. In some embodiments, the video segments in the video sequence to be processed may be obtained locally by the terminal according to the operation of the user, or obtained by the terminal recording the video in real time according to the operation of the user. The user can adjust the arrangement sequence of the plurality of video clips according to the requirement of the user, so that the video sequence is obtained.

It is understood that the time axis of the video sequence is determined collectively according to the time length of each video clip. For example, if the duration of the video clip a is 3 seconds, the duration of the video clip B is 6 seconds, and the duration of the video clip C is 4 seconds, then 13 seconds are total in the time axis of the video sequences obtained after sequential ordering, where the 0 th to 3 rd seconds on the time axis are the video content of the video clip a, the 3 rd to 9 th seconds are the video content of the video clip B, and the 9 th to 13 th seconds are the video content of the video clip C.

S204, at least two video special effects to be added to the video sequence are obtained.

Wherein the video special effect is used for presenting an enhanced video visual effect after being added to the video. The video special effect can be a material added to the video, and the material can be any one of a character material, a picture material or an animation material; the video special effect may also be a processing mode of controlling an effect attribute of video data to generate a change effect of a video, such as a time axis special effect, where the time axis special effect includes a speed change special effect, a circular special effect and a reverse special effect, the speed change special effect is a video effect of accelerated playing or decelerated playing by controlling a playing rate of a video frame, the circular special effect is a video effect of circular playing after video content is repeatedly played, and the reverse special effect is also called a time light reverse special effect and is a video effect of playing the video content in a reverse order of an original playing order. The plurality of video effects mentioned in the embodiments of the present application are two or more video effects.

Specifically, after acquiring the video sequence to be processed, the terminal may acquire at least two video effects to be added to the video sequence, where the at least two video effects may include video effects belonging to a plurality of different effect types, and may also include video effects belonging to the same effect type but spanning different time ranges. For example, the at least two video effects to be added to the video sequence may include at least two of a variable speed effect, a loop effect, and a reverse effect, may include at least two variable speed effects corresponding to different playback rates, and may include at least two loop effects corresponding to different loop times. In one embodiment, in the process of editing a video by a user, a plurality of video special effects to be added can be selected, and the terminal can acquire the plurality of video special effects selected by the user for a video sequence according to a video special effect adding operation triggered by the user for the video sequence.

S206, according to the time range of adding each video special effect, a special effect object of the video sequence is constructed.

The time range is a time range determined according to the starting time and the ending time of the video special effect application to the video sequence, and the time range can be any time range on the time axis of the video sequence. Specifically, when a user needs to add a video special effect to a video sequence in the process of editing the video, the time range of adding each video special effect to the video sequence needs to be determined. A user may add the same video effect across multiple video segments, for example, the user may need to add a reverse effect to a video sequence in a time range that lasts from the middle of a first video segment in the video sequence to the middle of a second video segment. The user may also add multiple video effects, and there may be overlap in the time ranges to which different video effects are added, for example, the user may specify that a reverse effect is to be added from 0 second to 4 seconds of the video sequence, and specify that a loop of 2 effects is to be added from 2 second to 6 second of the video sequence.

The effect object is a set of one or more video effects, how many of the video effects are at least two video effects, and a plurality of the video effects in the set have the same time range. The terminal constructs special effect objects according to the time range of adding each video special effect, and then processes the special effect objects in sequence, so that each special effect object is added to different time ranges, thereby avoiding the uncertainty caused by the overlapping of different special effect objects in the time ranges, and supporting the addition of a plurality of video special effects overlapped in the time ranges to a video sequence.

In one embodiment, constructing a special effects object for a video sequence according to a time range for adding each video special effect comprises: acquiring a time range for adding each video special effect to a video sequence; and constructing special effect objects of the video sequence according to the video special effects with the same time range.

The video effects with the same time range refer to the video effects with the same start time and the same end time applied to the video sequence. For example, in the process of editing the video, a user specifies to add a reverse special effect in the 0 th to 4 th seconds of the video sequence, specifies to add a loop special effect for 2 times in the 0 th to 4 th seconds of the video sequence, and adds a variable speed special effect in the 0 th to 6 th seconds of the video sequence, and since the end time of the variable speed special effect is different from the end time of the previous two video special effects, the terminal can construct the reverse special effect and the loop special effect in the 0 th to 4 th seconds into a special effect object, and construct the variable speed special effect in the 0 th to 6 th seconds into a special effect object.

And S208, after sequencing the special effect objects, obtaining the special effect objects in sequence.

Specifically, the terminal may sequence the special effect objects according to a preset sequencing rule, and sequentially obtain the special effect objects after sequencing, thereby sequentially adding the special effect objects to the video sequence.

In one embodiment, the terminal may sort the special effect objects in an ascending order of a time axis of a video sequence, and then sequentially obtain the special effect objects according to a sorting result; of course, the special effect objects may also be acquired in sequence according to the reverse order of the sorting result. In other embodiments, the terminal may also sort the special effect objects in a descending order of a time axis of the video sequence, and then sequentially obtain the special effect objects according to a sorting result.

In an embodiment, the video processing method further includes a step of sorting the special effect objects, as shown in fig. 3, the step specifically includes:

s302, a start time at which the video special effect included in each special effect object is added is obtained.

As mentioned above, the special effect object includes a video effect or a plurality of video effects in the same time range, and after each special effect object in the video sequence is constructed, the terminal may obtain the time range corresponding to the special effect object, where the time range is also the time range to which the video effect included in the special effect object is added, and the time range includes the start time and the end time. The terminal may acquire at least one of a start time and an end time at which the video effect is added in each effect object.

S304, sequencing the special effect objects according to the sequence of the starting time.

Further, the terminal may sort all the special effect objects in an ascending order or a descending order of the start time. For example, if one of the constructed special effect objects includes a reverse special effect added from 0 th to 4 th seconds of the video sequence and a loop special effect added from 0 th to 4 th seconds, the starting time of the special effect object is 0 th second, and the other special effect object includes a variable speed special effect added from 2 nd to 6 th seconds of the video sequence, the starting time of the special effect object is 2 nd seconds, the terminal may sort the two constructed special effect objects in the sequential order of the starting times. The embodiments of the present application are mainly described in the following description of sorting special effect objects in ascending order of start time.

In this embodiment, by sequencing the special effect objects according to the sequence of the start time of the included video special effects, each special effect object can be distinguished through a time range, the constructed special effect objects can be added to different time ranges of the video sequence, and a plurality of video special effects which are overlapped on the time range can be added to the video sequence.

In an embodiment, as shown in fig. 4, the video processing method further includes a step of sorting the special effect objects, and as shown in fig. 4, the step specifically includes:

s402, acquiring the time range of the video special effect included by each special effect object.

Specifically, the terminal may first obtain a time range of a video special effect included in each special effect object, and determine whether there are multiple overlapping special effect objects in the time range; if the video special effects do not exist, the terminal sorts the special effect objects according to the ascending order of the starting time of the video special effects included in the special effect objects in the mode shown in figure 3; if the video special effects exist, the terminal sorts the special effect objects of the video sequence according to the ascending sequence of the starting time of the video special effects included in the special effect objects, and then the sorting of the special effect objects with overlapped time ranges is adjusted.

S404, when at least two special effect objects with overlapping time ranges exist, respectively obtaining priorities of video effects included in the at least two special effect objects.

Specifically, the terminal may determine whether there are a plurality of special effect objects whose time ranges overlap, according to the time ranges of the respective special effect objects. For example, if one of the constructed special effect objects includes a reverse special effect added in 0 th to 4 th seconds of the video sequence and the other special effect object includes a loop special effect added in 2 nd to 6 th seconds, the terminal determines that the time ranges of the two special effect objects overlap, and in this case, the terminal needs to determine the priorities of the plurality of special effect objects.

In one embodiment, the priority of the special effect object is determined according to the priority of the video effect included in the special effect object, and the terminal may obtain the priorities set in advance for different types of video effects, so that the priority of the special effect object depends on the video effect with the highest priority included in the special effect object. For example, if the priority of the loop effect is higher than that of the variable speed effect and the priority of the variable speed effect is higher than that of the reverse effect, when there is an overlap between the time ranges of the two effect objects, it is assumed that one of the effect objects includes the loop effect and the reverse effect, the priority of the effect object is the priority of the loop effect, and the other effect object includes the variable speed effect, the priority of the effect object is the priority of the variable speed feature, and it is obvious that the priority of the former effect object is higher than that of the latter effect object. Optionally, if there are multiple overlapping special effect objects with the same priority in the time range determined by the priority of the included video special effect, the terminal may continue to perform secondary sorting on the multiple special effect objects with the same priority according to the start time of the time range.

It should be noted that, the priority of the video special effect and the ordering rule of the special effect object both affect the final video visual effect, so the priority of the video special effect can be set according to the actual requirement, and the ordering rule of the special effect object can also be set according to the actual requirement.

S406, at least two special effect objects are sequenced according to the priority of the video special effect.

Specifically, the terminal may determine the priority of the special effect objects according to the priority of the video special effect, and thus sort according to the priority of the special effect objects.

In one embodiment, ordering the at least two effect objects according to a priority of the video effect comprises: when the special effect object comprises a video special effect, determining the priority of the special effect object according to the priority of the video special effect; when the special effect object comprises at least two video special effects, determining the video special effect with the highest priority in the at least two video special effects; determining the priority of the special effect object according to the priority corresponding to the highest video special effect; and sequencing at least two special effect objects according to the priority of each special effect object.

In this embodiment, after the special effect objects are sorted according to the preset priority rule of the video special effect, a predictable video processing result can be obtained in the subsequent processing process of the special effect objects.

And S210, adding the first special effect object to the video sequence to generate a new video sequence, repeating the step of adding the next special effect object to the video sequence generated last time to generate a new video sequence, and obtaining the target video sequence until the last special effect object is added to the video sequence generated last time.

The target video sequence is obtained after the video special effects to be added to the video sequence are added, and the terminal can preview or play the target video sequence and check richer video visual effects.

Specifically, after the terminal constructs and sequences the special effect objects of the video sequence, the terminal may sequentially obtain each special effect object in the sequencing result, add the first special effect object in the sequencing result to the video sequence to generate a new video sequence, add the second special effect object to the video sequence generated last time to generate a new video sequence of the current time, and so on, repeat the step of adding the next special effect object to the video sequence generated last time to generate a new video sequence until the last special effect object in the sequencing result is obtained, and add the last special effect object to the new video sequence generated last time to obtain the target video sequence.

In one embodiment, before obtaining the target video sequence, the terminal may obtain a video derivation operation triggered by a user, and perform a complete video encoding and decoding process on a new video sequence generated finally according to the video derivation operation, so as to obtain video data with an expected video effect.

According to the video processing method, after the special effect objects of the video sequence are constructed according to the time range of adding each video special effect, the special effect objects are sequenced, only one special effect object is added to the video sequence each time after the sequencing, so that the serial processing of each special effect object is realized, for the video sequence, a new video sequence is generated after a single special effect object is added to the whole video sequence each time, the parallel processing of a plurality of video fragments in the video sequence is realized, and the target video sequence is output until all the special effect objects are processed. On one hand, the whole process of adding the special effect object does not need to carry out a complete encoding and decoding process on all video data for many times, so that the efficiency of adding the special effect to the video sequence can be improved; on the other hand, each special effect object is added to different time ranges of the video sequence through serial processing of the sequenced special effect objects, so that uncertainty caused by overlapping of the time ranges is avoided, the time range of the video special effect can be supported to span multiple video clips, and overlapping of the adding time ranges of the multiple video special effects can also be supported.

In one embodiment, as shown in fig. 5, each time a new video sequence is generated by adding a special effect object to the video sequence, the terminal may perform the following steps:

s502, according to the priority of the video special effects, the video special effects included by the special effect objects are sequenced.

Specifically, since the special effect object includes a plurality of different types of video special effects having the same time range, the terminal may sort the video special effects included in the currently processed special effect object according to the priorities of the different types of video special effects.

S504, video special effects in the special effect objects are sequentially obtained.

Specifically, the terminal may sequentially obtain each video special effect in the sorting result.

And S506, adding the first video special effect in the special effect object to the video sequence to generate a new video sequence, repeating the step of adding the next video special effect in the special effect object to the new video sequence generated last time to generate the current new video sequence, and obtaining the new video sequence added with the special effect object until the last video special effect in the special effect object is added to the new video sequence generated last time.

Specifically, after sequencing the video effects included in the current effect object, the terminal may sequentially acquire each video effect in the sequencing result, add the first video effect in the sequencing result to the video sequence to generate a new video sequence, add the second video effect to the video sequence generated last time to generate a new video sequence at the current time, and repeat the step of adding the next video effect to the video sequence generated last time to generate a new video sequence until the last video effect in the sequencing result is acquired, and add the last video effect to the new video sequence generated last time to obtain a new video sequence to which the effect object is added.

For example, the following steps are carried out: the terminal constructs n special effect objects for a video sequence, the terminal obtains the special effect objects in sequence after sequencing the n special effect objects, and when the ith special effect object is obtained and added to the video sequence generated at the previous time and a new video sequence is generated, the terminal executes the following steps:

acquiring a latest video sequence S generated after adding the 1 st to the i-1 st special effect objects;

sequencing k video effects included by the ith effect object according to the priority of the video effects;

obtaining video effects from a sequencing result in sequence, adding the 1 st video effect in the sequencing result to the generated latest video sequence S to generate a latest video sequence, repeating the step of adding the mth video effect in the sequencing result to the video sequence generated at the previous time to generate a new video sequence until the kth video effect in the sequencing result is added to the video sequence generated at the previous time to obtain the latest video sequence generated after the ith special effect object is added;

wherein n, m and k are positive integers, i is more than or equal to 1 and less than or equal to n, i is an integer, and m is more than or equal to 2 and less than or equal to k.

In one embodiment, in step S210, adding the first special effect object to the video sequence to generate a new video sequence, and repeating the step of adding the next special effect object to the video sequence generated last time to generate a new video sequence until the last special effect object is added to the video sequence generated last time to obtain the target video sequence, including: and inputting the first special effect object and the video sequence into a first special effect constructor to generate a new video sequence, repeating the step of inputting the next special effect object and the video sequence generated last time into the next special effect constructor to generate the new video sequence until the last special effect object and the video sequence generated last time are input into the last special effect constructor to obtain the target video sequence.

Specifically, the terminal may add the special effect object to the video sequence through the special effect constructor to generate a new video sequence, sequence all the special effect objects of the video sequence, sequentially acquire the special effect objects in the sequencing result, and add the input special effect object to the latest video sequence generated at the previous time through the special effect constructor. The input of the special effect constructor is a special effect object and the latest video sequence generated in the previous time, and the processing flow in each special effect constructor is consistent.

In one embodiment, as shown in fig. 6, the effect constructor includes at least one effect processing unit, and the step of generating a new video sequence after the effect constructor adds the effect object to the video sequence includes:
