What it does
Turns 16:9 footage into 9:16 for Reels, Shorts and TikTok. Instead of a fixed centre crop, it tracks the subject and moves the crop window so they stay in frame.
How it works
- Detects and tracks the subject frame by frame.
- Smooths the crop path so the virtual camera doesn’t jitter.
- Renders the reframed video in batch, so a whole folder can be processed overnight.
