Create custom variable speed changes
You can manually divide a clip into segments and assign each segment its own speed
setting.
1. In the Final Cut Pro timeline, position the playhead or the skimmer at the frame where
you want to begin a new speed segment.
2. Click the Retime pop-up menu below the viewer and choose Blade Speed (or press
Shift-B).
The retime editor appears above the clip (If it wasn’t already shown), and the clip is
divided into two speed segments.
3. To set the speed for the newly created segments, do one of the following:
• Double-click the retime editor above one of the speed segments. Then, in the
Custom Speed window, set a new speed by selecting either Rate or Duration and
entering a speed percentage or a duration. Click anywhere outside the Custom
Speed window to close it.
• Drag the right edge of a speed segment in the retime editor.
4. To create and modify additional speed segments, repeat steps 1 to 3.
You can modify the transitions between segments to create smooth adjustments from
one speed to another. See
Add speed transitions in Final Cut Pro.
