How to Turn Zoom Recordings into YouTube Shorts Clips

To turn a Zoom recording into YouTube Shorts clips, crop your video vertically, trim to the best moments, and add captions. Vidulk's AI Clipper automates these steps for you.

Zoom Recording to YouTube Shorts Clips: How to Convert

1. Understand YouTube Shorts Requirements

YouTube Shorts must be vertical (9:16) or square (1:1), up to 3 minutes long, and at least 1080x1920 resolution for 9:16. Anything wider, like the standard Zoom 16:9 export, won't count as a Short. YouTube auto-generates captions, which you can edit in YouTube Studio.

2. Prepare Your Zoom Recording

Obtain consent from all participants before sharing clips.
Export the recording from Zoom (cloud or local). Speaker view is best, as it keeps the focus on the active speaker.
Note that Zoom exports in 16:9, so cropping is required for Shorts.

3. Convert to Vertical Clips

Manually: Import your 16:9 Zoom video into a video editor. Crop to the speaker's face for a 9:16 frame, trim to under 3 minutes, and export at 1080x1920.
Automated: Use Vidulk's AI Clipper app (iOS or Android). Paste your Zoom video link or upload the file. The AI finds the best moments, crops to vertical, and adds captions sized for YouTube Shorts.

4. Add and Edit Captions

Vidulk automatically adds captions to your clips, formatted for Shorts.
YouTube will also auto-generate captions when you upload. Edit them in YouTube Studio for accuracy.

5. Upload to YouTube as a Short

Upload your vertical, captioned video to YouTube.
Ensure the aspect ratio is 9:16 or 1:1 and the duration is 3 minutes or less.
YouTube will classify it as a Short if the specs are correct.

Vidulk's AI clipper (free to start, iOS + Android) finds the best moments in a long video and exports captioned vertical clips sized for the destination.
