Transform & compositing
Compositing is about placing and combining images: where a clip sits in the frame, how it blends with the layers below, and which parts show through. All of these controls live in the Inspector on the right when a clip is selected.
Position, scale, rotate and opacity
Inspector › Transform
Reframe or resize any clip, spin it, or make it partly see-through to reveal the layer underneath.
- Select a clip on the timeline.
- In the Inspector, open Transform and adjust Position, Scale, Rotation and Opacity.
- Use Fit to frame to reset a clip to full frame and clear any transform animation.
You can also drag a clip directly in the preview to reposition it.

Blend modes
Inspector › Transform › Blend
Change how a clip mixes with the layers below: great for light leaks, textures and overlays.
- Stack a clip on a track above another.
- Set its Blend mode: Screen and Lighten add light, Multiply and Darken deepen, Overlay boosts contrast, Difference inverts.
- Combine with Opacity to dial in the strength.
Keyframe animation
Inspector › Animation
Animate transform values over time, so a clip can pan, zoom or fade as it plays.
- Turn on Keyframe (animate) for the property you want to move.
- Add a keyframe, move the playhead, then change the value (or drag the clip in the preview).
- Pick an interpolation curve (Linear, Ease in, Ease out, Ease in-out) to shape the motion.
Use Clear animation to remove all keyframes from a property and go back to a static value.
Crop and masks
Inspector › Mask / Crop
Show only part of a clip with a crop, or a rectangle, ellipse or freeform polygon mask.
- Choose a mask shape: Rectangle, Ellipse or Polygon.
- Adjust position, size and Feather for soft edges; use Invert to hide the shape instead of keeping it.
- For a polygon, drag points in the preview, click an edge to add a point, double-click to remove one.
- Add a mask keyframe to animate the shape across the shot.
Green screen (chroma key)
Inspector › Green screen
Knock out a solid-color background so your subject sits over another layer.
- Enable Green screen on the clip.
- Tune Tolerance to remove more or less of the color, and Softness for cleaner edges.
- Use Despill to remove color fringing left on the subject.
Borders and censor blur
Inspector › Border / Censor
Frame a clip with a border, or hide a face, logo or plate with a moving blur.
- Add a border and set its thickness, color and opacity.
- Add a censor blur, position the region over what to hide, and set the blur strength.
- Use Track target so the blur follows a moving subject automatically.
