TikTok video limits
TikTok's help center says videos recorded in the app can be up to 10 minutes and uploaded videos up to 60 minutes. TikTok Studio lists uploads of 720×1280 or higher, MP4 or WebM. AIClipMaker.org exports MP4 at 720×1280, which meets that.
How to do it with AIClipMaker.org
- Open AIClipMaker.org and drop your video file (MP4, MOV or WebM).
- Set the start and end of the part you want, for example 12:00 to 22:00.
- 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.
What tends to work as a TikTok clip
- One idea per clip. A 30 to 60 second answer to a single question beats a 3-minute ramble.
- Start on the claim or the punchline, not on "so, yeah".
- Add captions and a cover in the TikTok editor before you post.
The same files work for Instagram Reels and YouTube Shorts.
