Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a video special effects processing method according to an exemplary embodiment, where the video special effects processing method is used in a terminal, as shown in fig. 1, and includes the following steps.
In step 101, when the fact that a video added with special effects is shot is detected, obtaining a special effect rate corresponding to shooting of each video segment in the video, wherein each video segment is controlled by shooting pause;

in step 105, all the obtained special effect video segments are sequentially combined according to the shooting pause time to obtain a shot special effect video.
The video special effect processing method disclosed by the disclosure can be applied to a terminal, a server and the like, and is not limited herein, and the terminal implementation equipment can be electronic equipment such as a smart phone, a notebook computer, a tablet computer and the like.
The following describes in detail specific implementation steps of a video special effect processing method provided in an embodiment of the present disclosure with reference to fig. 1.
Firstly, executing step 101, when detecting that a video with special effects is added to be shot, acquiring a special effect rate corresponding to shooting of each video segment in the video, wherein each video segment is controlled by shooting pause;
in this step, when a user wants to shoot a video added with a special effect, a special effect needs to be selected first, where the selected special effect may be a special effect of a virtual video, or may be a material for decorating a virtual video effect, and the material may be a picture animation, or a transparent flash animation, or may be an AR special effect, and the embodiment is not limited; after the special effect is selected, the video with the special effect is started to be shot, namely, the client detects that the video with the special effect is started to be shot, or the server detects that the video with the special effect is started to be shot through a Software Development Kit (SDK) for the special effect of the video image. And then acquiring a special effect rate corresponding to each video segment in the video, wherein when the video with the special effect added is detected to be started to be shot, the acquired special effect rate is an initial special effect rate, each video segment is controlled by shooting pause, and each video segment is normally controlled by a shooting user to pause.
In this embodiment, obtaining the special effect rate corresponding to each video segment in the captured video may be implemented by the following two ways:
one way is that, when a selection instruction input by a user is received for each video segment, the special effect rate of the special effect is selected according to the selection instruction, for example, according to the received user selection instruction, the special effect rate of shooting the special effect of the first video segment is selected to be 0.5, the special effect rate selected by the second video segment is selected to be 2, the special effect rate selected by the third video segment is selected to be 1, and the like. It should be noted that, for each video segment, the selected special effect rates may be the same or different, if the selected special effect rates are the same, it is indicated that the video and the special effect are recorded at a constant speed, and if the selected special effect rates are different, it is indicated that the video is normally shot, and the special effect rate is changed, that is, the special effect video is recorded according to the changed special effect rate.
The other mode is that a user obtains a special effect rate corresponding to each video segment according to a preset strategy; wherein the preset strategy comprises: and presetting a corresponding special effect rate according to the shooting time period of each video segment in the shot video. For example, the shooting time for shooting the first video segment is set to 2 seconds, and the special effect rate (also referred to as special effect rendering rate, the same below) for adding a special effect to the video segment is set to 0.5; shooting time for shooting a second video segment is 2 seconds, and setting a special effect rate for adding a special effect to the second video segment to be 2 seconds; shooting the third video segment for 4 seconds, and setting the special effect rate of adding the special effect to the third video segment to be 3 seconds; the shooting time for shooting the fourth video segment is 7 seconds, and the special effect rate for adding the special effect to the fourth video segment is set to be 5 seconds, and the like.
Next, step 102 is executed, in the process of shooting the video, a shooting time node for shooting each video segment is obtained, where the shooting time node includes: a shooting pause time and a shooting increment time.
In this step, during the shooting of the video, the shooting may be suspended as required, and when the shooting is suspended, the shooting suspension time during which the video is suspended from shooting and the shooting increment time of the currently shot video need to be recorded, where the shooting suspension time and the shooting increment time may be collectively referred to as a shooting time node.
That is, during shooting of the video, the user may pause shooting, continue shooting, and so on, that is, when it is detected that shooting of the video is paused, it is necessary to record a shooting time node for shooting the video segment, where the shooting time node includes a shooting pause time for shooting the video segment, and calculate a shooting increment time of the current video segment according to the shooting pause time, for example, shooting of the video is paused for 2 seconds, the shooting pause time is 2 seconds, and the actual shooting increment time is 2 seconds, and so on.
Other processes for pausing the shooting of the video are similar to the above processes, and are described in detail above, and are not described again here.
And step 103 is executed, and the special effect rendering time of each video segment is determined according to the special effect rate and the shooting increment time of each video segment.
In this step, one determination method is:
multiplying the special effect rate of each video segment by the shooting increment time of the corresponding video segment to obtain the special effect rendering increment time of each video segment; adding the special effect rendering increment time of each video segment to the special effect pause time of the previous video segment to obtain the special effect pause time of the corresponding video segment; and then adding the special effect pause time of each video segment to the product of the shooting increment time of the corresponding video segment and the special effect rate (namely the special effect rendering increment time of the corresponding video segment) to obtain the special effect rendering time of each video segment.
For example, when it is detected that a video starts to be shot, the video and a special effect are shot simultaneously, the shooting time node for starting to be shot is 0, and a special effect rate (i.e., a special effect rendering rate) is set to be 0.5. Then, assuming that the video is paused after being shot for 2 seconds, the shot time of the video segment is recorded for 2 seconds, the shot increment time of the video is 2 seconds, and correspondingly, the special effect rendering increment time 2 × 0.5 is 1, that is, the shot increment time is multiplied by the special effect rate. And then, setting the special effect rate of the second video segment, if the special effect rate is 2, continuing to shoot the video, pausing after beginning to shoot the second video segment for 2 seconds, wherein the shooting time of the video is 4 seconds, the shooting increment time of the shooting video is 2 seconds, correspondingly, calculating the special effect rendering increment time of the second video segment according to the special effect rendering increment time of the first video segment, the special effect rate of the second video segment and the shooting increment time of the second video segment, and the special effect rendering increment time of the second video segment is 2.5 + 2-5.
By analogy, the shooting pause time and the shooting increment time for shooting each video segment of the video, and the corresponding special effect rendering increment time, the special effect pause time and the special effect rendering time can be obtained.
And then, executing step 104, and rendering the special effect into the corresponding video segment according to the special effect rendering time of each video segment to obtain the corresponding special effect video segment.
Specifically, in this step, each frame of special effect image is inserted, fused or superimposed into each frame of video image of the corresponding video segment according to the special effect rendering time of each video segment, so as to obtain the corresponding special effect video segment. The insertion or blending or overlaying is processed according to the existing video frame insertion or blending or overlaying technology, for example, by a video image special effect software development kit (sdk, software development kit), the special effect is added to the corresponding video segment according to the special effect rendering time of each video segment, and the corresponding special effect video segment is obtained. The specific processing procedures are well known to those skilled in the art and will not be described herein.
Finally, step 105 is executed to combine all the obtained special effect video segments in sequence according to the shooting pause time to obtain the shot special effect video.
In this step, the special effect video segments are sequentially spliced according to the time sequence of the shooting pause time to obtain a complete shot video, and the specific video splicing is well known to those skilled in the art and is not described herein again.
In the embodiment of the disclosure, when the fact that a video added with special effects starts to be shot is detected, a special effect rate corresponding to each video segment in the shot video is obtained; acquiring a shooting time node for shooting each video segment in the process of shooting the video; then, determining the special effect rendering time of each video segment according to the special effect rate and the shooting time node of each video segment; and finally, rendering the special effect into the corresponding video segment according to the special effect rendering time of each video segment to obtain the corresponding special effect video segment, and sequentially combining all the obtained special effect video segments according to the shooting pause time to obtain the shot special effect video. That is to say, in the embodiment of the present disclosure, the special effects are segmented separately, and different special effect rates are set for each segment of the special effects, so that the purpose of changing the special effect rate at will when the video is shot is achieved, the special effects can be adjusted at will when the video is shot, and the flexibility of shooting the special effect video is increased. By setting different special effect rates and independently managing the special effect rendering time, the problem that the special effect rendering rate can be adjusted in real time according to needs when the special effect video is shot is solved, the special effect rendering efficiency is improved, and the satisfaction degree of shooting the special effect video by a user is improved.
Optionally, in another embodiment, on the basis of the above embodiment, the method may further include: when the special effect video is finished, establishing a corresponding relation between a shooting pause time node and shooting increment time of each video segment for shooting the special effect video, and corresponding special effect speed, special effect rendering time and variable-speed special effect rendering increment time.
That is, when the special effect video shooting is completed, establishing a one-to-one correspondence relationship between a shooting pause time node and shooting increment time for shooting each section of video, and corresponding special effect speed, special effect rendering time and special effect rendering increment time after speed change; specifically, the corresponding relationship and the queue mode may be stored, or the corresponding relationship may be stored in a special effect time queue, so that the special effect time queue is applied to the overall special effect rate, and is convenient to use when the special effect video is subsequently photographed again.
In the embodiment, the special effect is added when the video is shot, so that the speed of the special effect can be changed in real time, and vivid slow motion or quick playing later effect can be realized through simple operation. By adopting the embodiment of the disclosure, the special effect of the video can be shot more flexibly, and the speed of the special effect can be changed at will in the shooting process according to the needs.
To facilitate understanding of those skilled in the art, please refer to fig. 2, which is a flowchart illustrating an application example of a video special effect processing method according to an embodiment of the present disclosure, in which rendering of all special effects is comprehensively managed by a video image special effect software development kit sdk, and a rendering rate during rendering is set for each special effect, so as to achieve a function of controlling playing of each special effect at a different rate. In the embodiment of the disclosure, in order to achieve the effect of suspending and adjusting the rate in real time to continue shooting, the embodiment of the disclosure completes time recording by recording the current rendering time queue, that is, each time of suspending is the last time of suspending plus the special effect rate multiplied by the shooting increment time. And will record the time node and store it in a queue for the next rate change or suspension. The method and the device solve the problem of adjusting the rendering rate of the special effect in real time during shooting in a mode of independently managing the rendering time of the special effect. It should be noted that, the effect rendering is updated according to time, so that a time-based shift characteristic is added to the effect sdk, and if it is desired to capture a shift effect, the shift characteristic is implemented, and the effect can be added to the shift queue. The method comprises the following steps:
Step 202: assuming that the video is paused after 2 seconds of shooting, the recording pause time is 2 seconds, the shooting increment time is 2 seconds, and correspondingly, the special effect rendering time 2 × 0.5 is 1 second.
Step 203: a set second segment of the special effect rate is obtained, if 2.
Step 204: and continuing to shoot the second video segment, and pausing after shooting for 2 seconds, wherein the shooting time of the video segment is 4 seconds, the shooting increment time is 2 seconds, and correspondingly, the special effect rendering time is 2 x 0.5+2 x 2 is 5.
Step 205: and acquiring the set third section special effect rate, and if the set third section special effect rate is 3.
Step 206: and continuing to shoot the third video segment, and pausing after shooting for 4 seconds, wherein the shooting time of the video segment is 8 seconds, the shooting increment time is 4 seconds, and correspondingly, the special effect rendering time is 2 × 0.5+2 × 2+4 × 3 is 13.
Step 207: and when an ending instruction of shooting the video is detected, shooting is ended, and complete special-effect videos are sequentially generated according to shooting pause time.
It should be noted that, after the step 206, and so on, a group of special effect time queues corresponding to the actual shooting increment time and the special effect rate one to one may be obtained finally, and the queue is applied to the overall special effect rate, so that the segmented speed change effect of the special effect may be completed. That is to say, when the video is shot, the special effect is added, so that the speed of the special effect can be changed in real time, and the later effect of visual slow motion or quick playing can be realized through simple operation. By adopting the method and the device, the special effect of the video can be shot more flexibly, and the speed of the special effect can be changed at will in the shooting process according to the needs.
