How does face tracking work?

AI samples frames at regular intervals, detects face positions using neural networks, then computes a smooth crop trajectory.

What if there are multiple faces?

The AI tracks the largest/most prominent face. Multi-face framing is coming soon.

What output formats are available?

9:16 (TikTok/Shorts), 4:5 (Instagram), 1:1 (Square), 2:3 (Pinterest), 16:9 (widescreen).

Does it work without faces?

Yes, but without faces the crop defaults to center. Face tracking gives the best results.

What's the output quality?

Free users get 720p with watermark. Pro users get full resolution.

How long does reframing take?

About 3-5 minutes for a 10-minute video due to face detection processing.

Can I reframe and add subtitles in one step?

They are separate tools for maximum flexibility. Reframe first to set the correct aspect ratio, then use our subtitle burn tool to add captions optimized for the new format.

Does smart reframe change the video duration?

No. Smart reframe only changes the aspect ratio and crop position — the duration, audio, and frame rate remain identical to the original.
