Turn wide footage into vertical or square clips. Keep your subject in frame with precise manual focus points or optional on-device tracking.
Editorial control, not guesswork.Review the crop path before rendering. Automatic tracking follows visual texture and may lose a subject.

HOW IT WORKS
More than a center crop.
Reframe creatively without uploading a video. Move the crop at different timestamps, track visual texture where useful, and preview the entire path before recording the result.
01Choose a video and a target aspect ratio.
02Drag to focus; add keyframes or run local tracking.
03Review and export the composition and its source metadata.
Using Video Auto Reframe
Reframe local video for a target aspect ratio with a manually positioned crop, optional texture tracking and a reviewable focus path.
Workflow
Open a browser-decodable video and choose a ratio
place crop and add keyframes, optionally run NCC texture tracking
inspect the path and quality checks, then export video, still, QA JSON or settings.
Example
For a vertical post from landscape footage, set 9:16, place the crop on several keyframes and track only while the textured patch stays visible. Review the whole clip.
Limits and data handling
Not face/person recognition: NCC follows texture and stops at low confidence. Source caps at 350 MB; export at 120 seconds, 1920 px per side and 3.7 MP. MediaRecorder pacing, codecs and audio vary, so output is not frame-accurate. Project JSON excludes footage; reattach the same video.
FAQs
Does tracking recognize faces or people?
No. It follows a textured patch and can drift after occlusion, zoom or rotation.
Does project JSON include the video?
No. It stores settings and metadata; reattach the source video to reopen.
