Detailed Description
The technical solutions of the present application are further described in detail below with reference to the drawings and examples.
Fig. 1 is a schematic flow chart of a video export method according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step 102: obtaining a first target video export instruction, wherein the first target video applies a first processing parameter to at least one segment of a reference video;
the first target video export instruction is used for exporting the first target video, the reference video may be a video source file, the first processing parameter may include at least one kind of processing parameter, the first processing parameter may be an editing parameter used when video editing is performed on the video source file, such as a filter parameter, a speed parameter, a contrast parameter, an audio parameter, etc., and the first processing parameter may also be an export parameter used when video exporting is performed on the edited video source file to obtain the first target video, such as a video format (e.g., MP4, MOV) and a resolution (e.g., 720P, 1080P, 4K) of the exported first target video; the same or different first processing parameters may be applied to different segments of the reference video to obtain the first target video.
In the case that the at least one segment includes a first segment, a second segment, a third segment, and a fourth segment, and the first processing parameter includes parameters X1, X2, and X3, the first target video may be obtained by applying the parameter X1 to the first segment, applying the parameter X2 to the second segment, and applying the parameter X2 and X3 to the third segment of the reference video, respectively.
Step 104: determining that a first video exists, the first video applying a second processing parameter to at least one segment of the reference video;
the first video may be a video file that has been derived, i.e. the first video is a video derived by applying the second processing parameters to at least one segment of the video source file; the video source file here corresponds to a reference video. Similar to the first processing parameters, the second processing parameters may include at least one kind of processing parameters, where the first processing parameters may be at least partially the same as or different from the second processing parameters, the second processing parameters may be editing parameters used when video editing is performed on the video source file, and the second processing parameters may also be derived parameters used when video derivation is performed on the edited video source file to obtain the first video; the same or different second processing parameters may be applied to different segments of the reference video to obtain the first video.
Step 106: if the segments with the same processing parameters as the first video in the first target video are determined, copying the same segments in the first video, and applying the first processing parameters to the segments with different processing parameters from the first video in the first target video to obtain the first target video.
The first target video and the first video can be compared according to the same time axis, and if the processing parameters of the fragments corresponding to the time sequences of the first target video and the first video are the same, the same fragment in the first video is copied; if the processing parameters of the first target video and the fragments corresponding to the time sequence of the first video are different, applying the first processing parameters to the fragments, which are different from the processing parameters of the first video, in the first target video to obtain the first target video; the segments corresponding to the time sequence refer to the first video and the segments corresponding to the starting time and the ending time of the video frame in the first video.
For example, when the first target video includes a first segment, a second segment, and a third segment, the first video includes a fourth segment, a fifth segment, and a sixth segment, the first segment corresponds to the fourth segment in time sequence, the second segment corresponds to the fifth segment in time sequence, the third segment corresponds to the sixth segment in time sequence, when the parameter X1 is applied to the first segment, the parameter X2 is applied to the second segment, the parameter X3 is applied to the third segment, the parameter Y1 is applied to the first segment, the parameter Y2 is applied to the second segment, and when the parameter X1 and the parameter Y1 are the same for the third segment, the parameter X3 and the parameter Y3 are the same for the first segment and the fourth segment in time sequence, and the parameter X2 and the parameter Y2 are different for the second segment and the fifth segment in time sequence, the fourth segment and the sixth segment in the first video and the fourth segment in the first video and the second segment in the second video are directly copied, and the parameter Y2 is applied to the first target video.
In the embodiment of the present application, by comparing the first target video to be exported with the exported first video, the segments of the first video having the same processing parameters as those of the first target video may be directly copied, and the first processing parameters may be applied to the segments of the first target video having different processing parameters from those of the first video, so that the export speed of the first target video may be increased.
Fig. 2 is a flowchart of another video derivation method according to an embodiment of the present application, as shown in fig. 2, where the method includes the following steps:
step 202: obtaining a first target video export instruction, wherein the first target video applies a first processing parameter to at least one segment of a reference video;
step 204: determining that i videos exist in a cache, and applying a j processing parameter to at least one fragment of the reference video by a j video, wherein j is an integer greater than or equal to 2 and less than or equal to i;
step 206: comparing the first target video with each of the i videos;
step 208: if the segments with the same processing parameters in the first target video and the i videos are determined, the same segments in the i videos are copied, and the first processing parameters are applied to the segments with different processing parameters in the first target video and the i videos, so that the first target video is obtained.
Wherein, similar to the method of comparing the first target video and the first video in step 106, for example, for the jth video in the i videos, the first target video and the jth video may be compared according to the same time axis, and if the processing parameters of the segments corresponding to the time sequences of the first target video and the jth video are the same, the same segment in the jth video is duplicated; if the processing parameters of the fragments corresponding to the time sequence of the first target video and the j-th video are different, applying the first processing parameters to the fragments, in the first target video, of which the processing parameters are different from those of the j-th video; and the fragments corresponding to the time sequence refer to fragments corresponding to the starting time and the ending time of the video frame in the first video and the jth video.
In the embodiment of the present application, by comparing a first target video to be exported with a plurality of videos to which processing parameters are applied on the same time axis, fragments of i videos, which are identical to the processing parameters of the first target video, may be directly copied, the first processing parameters are applied to fragments of the first target video, which are different from the i video processing parameters, so that materials that need to be repeatedly edited may be reduced to the greatest extent, and only the changed portions may be exported by encoding and decoding, so that the export speed of the first target video may be increased.
In some embodiments, as shown in fig. 3, after step 208, the method further comprises:
step 210: deriving the first target video;
step 212: storing the first target video as an i+1th video into the cache;
step 214: when a second target video export instruction is acquired, the second target video is compared to each of the i+1 videos.
And if the segments with the same processing parameters exist in the first target video and the i+1 videos, copying the same segments in the i+1 videos, and applying the first processing parameters to the segments with different processing parameters in the first target video and the i+1 videos, thereby obtaining the first target video.
As shown in fig. 4, it is assumed that the first target video needs to apply at least one first processing parameter to a first segment of the reference video, the first segment including at least a first sub-segment P1, a second sub-segment P2, a third sub-segment P3, a fourth sub-segment P4, a fifth sub-segment P5, a sixth sub-segment P6, a seventh sub-segment P7, and an eighth sub-segment P8, the i videos including the reference video and the derived first video, second video, and third video.
Assuming that the segment Q1 of the reference video corresponds to the third sub-segment P3 in time sequence and has the same processing parameters, and the segment Q2 of the reference video corresponds to the seventh sub-segment P7 in time sequence and has the same processing parameters; the segment Q3 of the first video corresponds to the first sub-segment P1 and has the same processing parameters, and the segment Q4 of the first video corresponds to the sixth sub-segment P6 and has the same processing parameters; the segment Q5 of the second video corresponds to the second sub-segment P2 and has the same processing parameters, and the segment Q6 of the second video corresponds to the fourth sub-segment P4 and has the same processing parameters; and if the segment Q7 of the third video corresponds to the fifth sub-segment P5 and the processing parameters are the same, copying the segments Q3, Q5, Q1, Q6, Q7, Q4 and Q2, and applying the first processing parameters to the segments P8 which are different from the i video processing parameters in the first target video to obtain the first target video.
The reference video may be an original video clip material (also called an original video clip source file script), the first video may be a first hidden copy of the original video clip material, the second video may be a second hidden copy of the original video clip material, the third video may be a third hidden copy of the original video clip material, when video files with different processing parameters need to be repeatedly exported, the video files which have been exported last time may be cached in a memory while being used as the hidden copy of the original video clip material, for the same engineering file, each exported video cache may be used as the hidden copy, so that a plurality of editable original materials may be obtained, when exported next time, hidden copies of different versions may be compared on the same time axis, the materials with the same format and parameters in the hidden copies and the video to be exported may be directly copied, and for the materials with changed parameters, real-time video encoding and export may be performed, and the video in the cache may be repeatedly utilized, so that the edited materials needing repeated editing may be reduced, and only the portion with changed export may be encoded and decoded, and the video may be updated and exported repeatedly, and the video may be updated.
Fig. 5 is a flowchart of still another video deriving method according to an embodiment of the present application, as shown in fig. 5, where the method includes the following steps:
step 502: obtaining a first target video export instruction, wherein the first target video applies a first processing parameter to at least one segment of a reference video; the first target video export instruction is used for exporting N target videos;

step 508: deriving an mth target video according to a preset time interval based on the derivation sequence of the N target videos; m is an integer greater than or equal to 2 and less than or equal to N; when the export sequence is 1 st, the first video is the reference video; when the export order is m, the first video comprises the reference video and video fragments of exported parts in the target videos of which the export orders are 1 st to m-1 st.
When a first target video is exported, the first target video can be compared with the reference video, if the same fragments as the reference video exist in the first target video, the same fragments in the reference video are copied, and the first processing parameters are applied to the fragments different from the reference video processing parameters in the first target video, so that the first target video is obtained; when deriving the fourth target video, comparing the fourth target video with the reference video and the video segments of the derived parts of the first target video to the third target video, if it is determined that the fourth target video and the reference video and the first target video to the third target video have segments with the same processing parameters, copying the same segments of the reference video and the first target video to the third target video, and applying the first processing parameters to the segments of the first target video, which are different from the processing parameters of the reference video and the first target video to the third target video, to obtain the fourth target video.
In some embodiments, the preset time interval may be denoted as t, and the second target video may be derived after the first target video is derived from the time t, where the second target video may directly copy the segments of the same format and parameters of the reference video derived portion and the first target video derived portion, and the third target video may be derived after the second target video is derived from the time t, where the third target video may directly copy the segments of the same format and parameters of the reference video derived portion, the first target video derived portion, and the second target video derived portion.
As shown in fig. 6, when it is required to derive videos with different parameters at the same time, video encoding and decoding derivation can be performed successively with a fixed time difference, when the video with a later time is derived, the video is compared with the derived video segment of the video with a earlier time, at time t1, the first target video is derived, the first target video is compared with the derived first segment of the reference video, at time t2, the second target video is derived, and the first segment and the second segment of the reference video, and the third segment of the first target video are compared. Thus, a plurality of video files with different parameters can be exported simultaneously, and 2 different video files can be exported in a time close to one video export time.
In the embodiment of the application, the video is exported successively at the preset time interval, and the video with the later time can be compared with the exported parts of other videos with the earlier time, so that the videos with various processing parameters can be exported simultaneously, and the export speed of the videos with the same material and different processing parameters is further accelerated.

step 507: determining the export sequence of the corresponding target video based on the category number of the first processing parameters corresponding to each of the N target videos;
the more the number of the types of the first processing parameters is, the later the export order of the target video is.
In the embodiment of the application, the video with more types of processing parameters can be derived later, and the video with less types of processing parameters can be derived preferentially, and the video with more types of parameters derived later can copy the part with the same parameters in the video with less types of parameters derived earlier, so that the deriving speed of the video can be further improved.
In some embodiments, prior to step 507, the method further comprises: acquiring the byte number of the first target video and/or the category number of the first processing parameters;
and applying the first processing parameter to at least one segment of the first target video to obtain the first target video under the condition that the byte number of the first target video is smaller than or equal to a first preset threshold value and/or the category number of the first processing parameter is smaller than or equal to a second preset threshold value.
In this embodiment of the present application, if the number of bytes of the first target video is smaller, or the types of processing parameters are smaller, the first processing parameters may be directly applied to at least one segment of the first target video, without comparing with other derived videos, so as to increase flexibility of video derivation.
In some embodiments, the method comprises the steps of:
step S702: obtaining a first target video export instruction, wherein the first target video applies a first processing parameter to at least one segment of a reference video; the first target video export instruction is used for exporting N target videos;
step S704: deriving according to a first mode for the 1 st to nth target videos, and deriving according to a second mode for the n+1th to nth target videos, wherein N is greater than or equal to 2 and less than N;
the first mode/the second mode includes step S7041: determining that i videos exist in the cache, and applying a j processing parameter to at least one fragment of the reference video by a j video; comparing the first target video with each of the i videos; if the segments with the same processing parameters in the first target video and the i videos are determined, copying the same segments in the i videos, and applying the first processing parameters to the segments with different processing parameters in the first target video to obtain the first target video;
the second mode/the first mode includes step S7042: determining that a first video exists, the first video applying a second processing parameter to at least one segment of the reference video; deriving an mth target video according to a preset time interval based on the derivation sequence of the N target videos; when the export sequence is 1 st, the first video is the reference video; when the export order is m, the first video comprises the reference video and video fragments of exported parts in the target videos of which the export orders are 1 st to m-1 st.
Wherein, in the case that the first mode includes step S7041 and the second mode includes step S7042, that is, the first mode is derived according to step S7041 for the 1 st to nth target videos and the second mode is derived according to step S7042 for the n+1 th to nth target videos.
In the case where the first mode includes step S7042 and the second mode includes step S7041, that is, the first mode is derived according to step S7042 for the 1 st to nth target videos and the second mode is derived according to step S7041 for the n+1 st to nth target videos.
In the embodiment of the application, the video can be exported in a mode of combining two export methods, so that the flexibility and the efficiency of video export are further improved.
