- Choose a clip length: 15, 30, 45, 60 or 90 seconds. You get up to 10 clips per run.
- Leave reframe on AI face tracking so each clip is cropped to 9:16 around the speaker.
- Download the 720×1280 MP4s and post them.
Before you post
Turn on "Upload at highest quality" in Instagram's media quality settings so the app doesn't compress your clip more than it needs to. Add captions in the Reels editor. If you post the same clip to TikTok, see TikTok clip maker.
