Video Auto Reframe

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

  1. Open a browser-decodable video and choose a ratio
  2. place crop and add keyframes, optionally run NCC texture tracking
  3. 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.
