Framing tools set what part of the source shows and how it sits on the canvas. They matter most when portrait footage meets a landscape project.
Crop a region Transform → Crop opens a full-screen editor: drag a rectangle over the part you want. The crop is non-destructive and re-editable.
Rotate and flip Quarter-turn rotations and horizontal or vertical flips live under Transform → Rotate & flip. A free-angle Tilt slider handles the in-between angles, with an optional fill so corners never show.
Choose the fill mode Frame offers Fit (letterbox), Fill (centre-crop to cover) and Blur BG, which letterboxes the clip over a blurred copy of itself. Blur BG is the usual fix for portrait clips in a landscape edit.
Set the canvas itself The aspect chip above the preview switches the project between 16:9, 9:16, 1:1 and 4:5. The colour swatch beside it sets what shows behind letterboxes and gaps.
Tips
Blur BG is set per clip, so you can mix it with hard cuts to full-frame footage freely.
Crop and Ken Burns both reframe, so a clip can carry only one of them. Pick the moving one when in doubt.
Overlays are always aspect-true; use Crop to reframe inside the box rather than stretching it.
