Basics
Splitting and Trimming
Split clips at the playhead and trim clip edges in Tooscut.
Splitting
- Move the playhead to the cut point.
- Select the clip.
- Press S.

Both halves keep all properties (effects, keyframes, color grading). Linked clips split together.
Trimming
Drag the left or right edge of a clip to adjust its boundary. Non-destructive — drag back out to restore trimmed material.
- Left edge right — Reveals a later portion of the source.
- Right edge left — Shortens from the end.
Select tool vs. razor tool
| Tool | Shortcut | Behavior |
|---|---|---|
| Select | V | Click to select clips, drag to move them, drag edges to trim |
| Razor | C | Click on any clip to split it at that point |
The razor tool splits without selecting first — just click where to cut.
Deleting clips
Select clips and press Delete or Backspace. Linked clips are deleted together.
Ripple editing
Press R or click the ripple icon in the timeline toolbar to toggle ripple mode.
When ripple mode is on:
- Deleting a clip shifts every clip after it on the same track left to close the gap.
- Trimming a clip's edge shifts downstream clips to match, so no gap opens or closes.
- Linked clips (audio + video pairs) ripple together. Other tracks are unaffected, and locked tracks never shift.
While dragging a ripple trim, ghost outlines preview where downstream clips will land. Turn ripple mode off to go back to normal trimming, which leaves gaps.
