Abstract

Various embodiments are disclosed for facilitating selective rendering during video editing. In accordance with one embodiment, a method of editing video comprises obtaining a video editing project, the video editing project including at least one video clip and timing information corresponding to the at least one video clip. The method further comprises obtaining a reference file generated according to the video editing project and obtaining, from a user, a modification for at least one segment in the video editing project. Based on the modification, each of the at least one segment is identified as a modified segment or an unmodified segment. Based on the identification of at least one modified segment, at least one corresponding segment is extracted from the reference file. The method further comprises applying the modification to the extracted at least one corresponding segment from the reference file, rendering only the extracted at least one corresponding segment, and combining the at least one rendered segment with a remaining portion of the reference file to generate an output file.

Claims

1. A method of editing a video, comprising:

obtaining a video editing project, the video editing project including at least one video clip appended together and timing information corresponding to the at least one video clip, each of the at least one video clip comprising a plurality of previously-rendered segments;

obtaining a reference file generated according to the video editing project;

obtaining modifications to the video editing project from a user for a plurality of segments in the at least one video clip, wherein the modifications comprise re-ordering of segments in a same video clip of the video editing project;

determining that no re-rendering is needed responsive to the obtained modifications comprising re-ordering of segments;

identifying each of the segments associated with the modifications as re-ordered segments, and any remaining segments as unmodified segments; and

combining the re-ordered segments of the reference file with unmodified segments of the reference file according to corresponding timing information to generate an output file, wherein combining is performed without re-rendering the previously-rendered segments.

2. The method of claim 1, wherein the reference file is updated according to the output file.

3. The method of claim 1, further comprising:

responsive to the modification to the video editing project comprising re-ordering of segments, re-ordering corresponding segments in the reference file, wherein re-ordering is performed without re-rendering the reference file.

4. The method of claim 1, wherein extracting corresponding segments from the reference file is performed based on timing information corresponding to the modifications in the video content.

5. The method of claim 1, wherein the reference file is hidden from the user, and wherein the output file is accessible by the user.

6. A method of editing a video, comprising:

obtaining a video editing project, the video editing project comprising a plurality of video clips appended together and corresponding timing information for each video clip, wherein each video clip comprises a plurality of previously-rendered segments;

obtaining a reference file generated according to the video editing project;

obtaining modifications to the video editing project from a user for a plurality of segments in at least one of the video clips, wherein the modifications comprise re-ordering of segments in the at least one of the video clips of the video editing project;

identifying each of the segments associated with the modifications as re-ordered segments and any remaining segments as unmodified segments; and

combining the re-ordered segments of the reference file and with unmodified segments of the reference file according to corresponding timing information to generate an output file, wherein combining is performed without re-rendering the previously-rendered segments.

7. The method of claim 6, wherein the reference file is inaccessible to the user.

8. The method of claim 6, further comprising generating a user interface displaying a representation of the video editing project displayed relative to a timeline component, the user interface further displaying representations of the plurality of video clips.

9. the method of claim 6, further comprising saving a copy of the output file as the reference file upon generation of the output file.
