Playback Interval (Video Trim)

Manually change the start and end intervals of the video clip. Generally, if the video is a background element that continues to show irrelevant content, there is no need to edit the playback interval.

However, if the video involves a speaker, you may need to adjust the intervals to match the subtitles, so editing the playback interval is essential.

We'll provide detailed instructions on how to change the video playback interval. Ah, changing the playback interval of the video and the uploaded voice file can be done in the same way!
