Abstract

The present disclosure provides an effect application previewing method, an apparatus, a device and a storage medium. The method includes: taking, in response to a preview trigger operation for a target effect style, a position of a pointer on a video track as a start point, to generate a virtual video frame for the target effect style; synchronously playing the virtual video frame and at least one video clip corresponding to the virtual video frame on the video track based on a timeline, to preview an effect of the target effect style applied to the at least one video clip.

First claim

What is claimed:

1. An effect application previewing method, comprising:
taking, in response to a preview trigger operation for a target effect style, a position of a pointer on a video track as a start point, to generate a virtual video frame for the target effect style; and
synchronously playing the virtual video frame and at least one video clip corresponding to the virtual video frame on the video track based on a timeline, to preview an effect of the target effect style applied to the at least one video clip;
wherein the taking, in response to the preview trigger operation for the target effect style, the position of the pointer on the video track as the start point, to generate the virtual video frame for the target effect style, comprises:
taking, in response to the preview trigger operation for the target effect style, the position of the pointer on the video track as the start point, to generate the virtual video frame for the target effect style on a virtual track, wherein the virtual track has a hierarchical relationship with the at least one video track, and
wherein the virtual track is located on an upper layer than each video track of the at least one video track, and pictures of the virtual track block pictures of each video track of the at least one video track.

2. The method according to claim 1 , wherein a length corresponding to the virtual video frame is same as a display duration of the target effect style, or the length corresponding to the virtual video frame is same as a length from the start point to a preset end point.

3. The method according to claim 2 , wherein the taking, in response to a preview trigger operation for a target effect style, a position of a pointer on a video track as a start point, to generate a virtual video frame for the target effect style, comprises:
taking, in response to the preview trigger operation for the target effect style, the position of the pointer on the video track as the start point, to generate the virtual video frame for the target effect style on a virtual track, wherein the virtual track has a hierarchical relationship with the at least one video tracks.

4. The method according to claim 1 , wherein the target effect style comprises an animation-type effect style and a static-type effect style.

5. The method according to claim 1 , further comprising:
displaying, in response to the preview trigger operation for the target effect style, the target effect style on a video picture being played in a video playing window.

6. The method according to claim 1 , further comprising:
displaying, in response to the preview trigger operation for the target effect style, the target effect style on a video picture being played in a video playing window.

7. An effect application previewing apparatus, comprising:
a generation module, configured to take, in response to a preview trigger operation for a target effect style, a position of a pointer on a video track as a start point, to generate a virtual video frame for the target effect style; and
a playing module, configured to synchronously play the virtual video frame and at least one video clip corresponding to the virtual video frame on the video track based on a timeline, to preview an effect of the target effect style applied to the at least one video clip,
wherein the generation module is configured to:
take, in response to the preview trigger operation for the target effect style, the position of the pointer on the video track as the start point, to generate the virtual video frame for the target effect style on a virtual track, wherein the virtual track has a hierarchical relationship with the at least one video track, and
wherein the virtual track is located on an upper layer than each video track of the at least one video track, and pictures of the virtual track block pictures of each video track of the at least one video track.

8. The apparatus according to claim 7 , further comprising:
a displaying module, configured to display, in response to the preview trigger operation for the target effect style, the target effect style on a video picture being played in a video playing window.

9. The apparatus according to claim 1 , further comprising:
a displaying module, configured to display, in response to the preview trigger operation for the target effect style, the target effect style on a video picture being played in a video playing window.

10. The apparatus according to claim 7 , wherein a length corresponding to the virtual video frame is same as a display duration of the target effect style, or the length corresponding to the virtual video frame is same as a length from the start point to a preset end point.

11. The apparatus according to claim 7 , wherein the target effect style comprises an animation-type effect style and a static-type effect style.

12. A non-transitory computer-readable storage medium, wherein instructions are stored in the non-transitory computer-readable storage medium, and when the instructions are run on a terminal device, the terminal device is enabled to implement an effect application previewing method,
wherein the effect application previewing method comprises:
taking, in response to a preview trigger operation for a target effect style, a position of a pointer on a video track as a start point, to generate a virtual video frame for the target effect style; and
synchronously playing the virtual video frame and at least one video clip corresponding to the virtual video frame on the video track based on a timeline, to preview an effect of the target effect style applied to the at least one video clip;
wherein the taking, in response to the preview trigger operation for the target effect style, the position of the pointer on the video track as the start point, to generate the virtual video frame for the target effect style, comprises:
taking, in response to the preview trigger operation for the target effect style, the position of the pointer on the video track as the start point, to generate the virtual video frame for the target effect style on a virtual track, wherein the virtual track has a hierarchical relationship with the at least one video track, and
wherein the virtual track is located on an upper layer than each video track of the at least one video track, and pictures of the virtual track block pictures of each video track of the at least one video track.

13. A device, comprising: a memory, a processor, and a computer program stored in the memory and run on the processor,
wherein upon executing the computer program, the method according to claim 1 is achieved by the processor.

14. A device, comprising: a memory, a processor, and a computer program stored in the memory and run on the processor,
wherein upon executing the computer program, the method according to claim 2 is achieved by the processor.
