Auto crop video
Every platform wants a different frame. FrameOS auto-crops a video to whichever aspect ratio you export — 9:16, 4:5, 1:1, or 16:9 — tracking the subject so the crop follows the action instead of cutting it off.
Pick the ratio, FrameOS finds the frame
Choose 9:16 for Shorts and Reels, 4:5 for a feed post, 1:1 for a square crop, or keep 16:9 — FrameOS recalculates the crop for each ratio so the subject stays centered instead of getting cut off at the edges.
Safe zones, not just a center crop
A blind center crop clips faces and buries captions under a platform's UI. FrameOS keeps the subject and caption placement inside each platform's safe area, so nothing important sits behind a profile icon or a share button.
Follows the subject, not a fixed box
When the speaker moves or the framing changes, a static crop window drifts off target. FrameOS tracks the subject through the clip and adjusts the crop, so an auto-cropped clip still looks intentional rather than mechanically cut.
One clip, every ratio, no re-editing
Export the same clip at multiple ratios for different platforms without rebuilding the edit — the crop recalculates per ratio while the cuts, captions, and pacing stay the same.

FAQ
What aspect ratios does auto-crop support?
9:16, 4:5, 1:1, and 16:9 — pick the ratio per export and FrameOS recalculates the crop for it.
Does auto-crop just center-crop the frame?
No — it tracks the subject through the clip, so the crop follows the action instead of holding a fixed box that can cut people off.
Will captions get hidden behind platform UI?
FrameOS keeps captions and the subject inside each platform's safe zone, so they stay clear of overlays like the TikTok caption bar or Reels UI.
