Fusion Keyframe Editor: Control Timing Without Fighting the Graph

1. Keyframe Editor and Spline Editor solve different problems

Use Keyframe Editor for timing: when animation starts, ends and which parameters should line up. Use Spline Editor for the shape and speed of value changes.

2. Move an animation block as a unit

Select several keys and shift them together. Relative spacing stays intact, so a finished motion can be moved later in the comp without rebuilding it.

3. Synchronize multiple parameters

Position, Size, Angle and Blend often need aligned start/end points. The Keyframe Editor makes timing drift easy to see and correct.

4. Copy animation intentionally

Keys can be transferred between compatible parameters or nodes, but value ranges must make sense. A technically possible copy is not always a meaningful motion design choice.

5. Use Spreadsheet for exact frame numbers

When exact timing matters, Spreadsheet is often faster than dragging keys visually. It turns the animation into explicit time/value data, which is useful for matching several elements.

6. Mini exercise

1. 1Create a Transform and animate Position.
2. 2Add Scale and Opacity/Blend animation.
3. 3Move all keys 12 frames later.
4. 4Move only the Opacity start 4 frames earlier and compare the feel.
