Drop any horizontal video. FrameFlow crops it to 9:16 and tracks your subject across every frame — no manual keyframes, no crop errors. Ready for Instagram Reels in seconds.
No sliders. No region selection. Drop your video, pick 9:16, get a perfectly cropped result. FrameFlow detects and centers your subject automatically.
Subject walks left? Camera pans? FrameFlow's AI tracking locks on and follows, adjusting the crop window dynamically frame by frame.
Upload five clips at once. Process them all in one run. Great for podcasters, course creators, and content teams repurposing long-form video.
9:16 for Reels and Shorts. 1:1 for Feed posts. 4:5 for Stories. Switch formats in one click without re-processing.
Most tools crop and freeze. FrameFlow tracks. When your subject moves from center to edge, the crop window shifts with them. When two people are in frame, the AI decides which one to prioritize based on motion and composition.
This is the part that separates a polished vertical clip from one that looks obviously auto-cropped.
Shoot once. Post everywhere.
Stop recreating content for every platform. Your best video is already horizontal — FrameFlow makes it vertical without losing the story.
