How to add your knowledge
Table of contents
No headersFrames are added or removed from either the head or the tail of the segment, depending on the location of the cursor and whether Lock is enabled or disabled.
(a) Lock button
When Lock is enabled, the segment or transition under the cursor is locked to the cursor, so the trim occurs at the other end of the segment. Locking segments controls whether the head or tail frames are affected during trimming. This is useful if you want to trim without affecting transitions such as dissolves. Clip information such as number of head and tail frames appears in black on selected segments.
| Cursor | Effect of Using Trim Lock |
|---|---|
| Trim Tail | The tail is locked, so the head of the segment is trimmed. |
| Trim Head | The head is locked, so the tail of the segment is trimmed. |
| Slide | The head and tail of the segment being trimmed are locked, so the head and tail of the connecting segments are trimmed. |
| Slide Transition | The head and tail of the transition being trimmed are locked, so the head and tail of the connecting segments are trimmed. |
| Slip | No effect. |
The effects of using Lock are illustrated in the trimming operations throughout this section.
NoteWhen trimming timewarps, there is a third lock option—Both. See Trimming a Timewarp.
