Navigate before editing
Choose Edit. Use Fit to see the entire sequence, Zoom In and Zoom Out for detail, and Go to Selection to return to the selected clip. Show Clip List lists clips by track when the timeline is crowded or dragging is inconvenient.
Tap a clip to select it. Select Multiple adds or removes clips from a selection. Check the selection label before a batch operation; the playhead and selected clip are independent.
The Sequence and timeline options menu includes Snap to edit points and Linked selection. Snapping helps align an edit. Linked selection keeps related picture and audio together. Track-label menus provide locking and muting; unlock a track before trying to edit its clips.
Split and remove a section
- Select the clip and place the sequence playhead inside it.
- Tap Split in the action bar, or choose Split at Playhead from the clip actions.
- Select the piece you intend to remove.
- Choose the appropriate named removal command in Tools → Commands: Ripple Delete closes the interval; Replace with Gap preserves that interval.
- Play across the result and check sound and later clips.
The touch clip actions also offer Lift, which removes the selected material using the lift/delete-selection path. Do not infer ripple behavior from a trash icon alone; use the named command for the timing result you want.
Trim with an absolute frame position
Open the clip actions and choose Precision Edit…. Pick Trim Start, Trim End, or Move. Enter the absolute Sequence frame, use −1 frame or +1 frame, or choose Use Playhead. Check the displayed timecode and tap Apply.
For a 24 fps sequence, a start position of frame 48 is two seconds from the sequence start. This field is a position, not “remove 48 frames.” Trim End uses an exclusive boundary: that frame is the first one after the clip.
Move can apply to the captured multiple selection. Trim applies to the chosen clip and its linked media. If the project or selection changes while the form is open, cancel and reopen the edit with the intended context.
Apply relative precision operations
Select a clip, tap Trim, or open Tools → Precision Trim. Choose an Operation, enter an Amount, and tap Apply, or use a small step button. Read the displayed unit: the typed Amount is seconds for Ripple In/Out, Roll, and Slide; Slip takes frames. The small ±1/±5 buttons apply frame steps. Source slip steps can use recorded-source frame units, while the other fine steps use sequence frames.
Trim changes an edge. Ripple adjusts downstream timing. Roll changes the shared cut between neighbors while preserving their combined duration. Slip changes the source content inside a fixed timeline interval. Slide moves a clip while adjusting its neighbors. Source handles, track locks, and neighboring material limit valid edits.
Change speed without losing the timing context
Select a media clip and open Tools → Speed & Retiming, or Inspector → Speed → Speed, range, reverse and hold. Choose Operation: Change speed, Change range speed, Reverse, Freeze at playhead, or Insert hold. Check Following edits before accepting a duration change.
Speed multiplier is relative to the current speed. Range changes use Range In and Range Out (exclusive); Snap Range to Sequence Frames aligns those bounds. Read the proposed clip and sequence durations, and check the captured linked-component state before Apply Retiming.
Frame sampling, Preserve audio pitch, and Pitch shift affect motion/sound treatment. Optical-flow quality and actual rendering depend on source and device; selecting it is not a universal quality guarantee. Held source audio is silent while other tracks continue. Review the entire changed interval after applying.
Undo, redo, and preserve checkpoints
Use Undo in the editing actions, or find Undo and Redo in Tools → Commands. A connected keyboard uses ⌘Z and ⇧⌘Z. While typing, those shortcuts belong to the text field; finish typing and focus the timeline before undoing a timeline edit.
Save a named version before a major rearrangement using Project Options → Versions. Versions are deliberate checkpoints, while Undo and Redo traverse editing history. A checkpoint still needs its media. Resolve save or draft warnings before switching projects.
