Manual crop with keyframes

What it does

Lets you choose which part of the image is visible and change it over time. Select a clip in the viewer and click Reframe: Crop opens, where you mark each change with New keyframe.

When to use it

When the automatic framing doesn't follow what you want to show, or for a one-off zoom.

What it doesn't do

It doesn't fight the automatic framing: manual keyframes override Auto Reframe for that section.

What it needs

Nothing but the sequence open in the editor.
