Common Questions

Frequently asked

What is the difference between Autocrop and AI Clipping?

AI Clipping automatically discovers highlights from a full video. Autocrop lets you specify an exact segment (start and end time) and reframes it to your chosen aspect ratio — no highlight detection involved.

What aspect ratios are supported?

Currently supported aspect ratios are 9:16 (vertical), 1:1 (square), and 4:5.

How is cost calculated?

Cost is based on the duration of the segment being cropped: /bin/zsh.05 per minute of input plus a fixed /bin/zsh.05 per clip.

Can I process multiple segments at once?

Each request processes one segment. Submit multiple requests to crop different segments from the same video.
