Preview overlays are visual guides only. They do not appear in exports.
Select the subject by clicking the source preview; this box provides a visual pattern for motion tracking.
Optional, gentle offset along the tracked direction. Disabled around suspected cuts; review the crop near frame edges.
Tracking follows local image patterns; it is not face or person identification. Review cuts and occlusions. Place a manual subject anchor at or before the trim start. Analyze up to 140 seconds / 420 samples at a time.

Available types depend on your browser. MP4 may use a browser-selected codec rather than H.264.
The browser captures the source soundtrack when available. Files without audio stay video-only; unsupported audio capture is reported. No sound plays through your speakers during export.

Frequently asked questions
Does subject tracking use an AI model?
This version uses image-template matching near a point you select, not an AI model that identifies people. Motion lead can reserve a little space in the travel direction. It is suitable for moderate movement and textured subjects; fast motion, zooms, scene cuts and occlusion can cause drift. Manual keyframes help correct the crop. You can undo/redo framing edits and jump to low-quality tracking samples.
Why is WebM or MP4 missing from the export menu?
Browsers only expose containers and codecs they can record. The studio checks MediaRecorder support at runtime and offers available types. A supported type may still fail if the device runs out of resources.
Will the exported video have audio?
The studio tries to route source sound into the output recording when enabled and browser facilities permit it. It cannot guarantee audio on every browser and media type. Always play back your export before publishing.
