Offsets

Offsets are reference numbers that indicate the change, in frames, that takes place when you trim. Offsets are displayed at both the head and tail of each segment.

Trimming heads or tails towards the left on the timeline results in a negative offset and trimming towards the right results in a positive offset. Offsets are created as follows.

Offset | Action | Result Offset
--- | --- | ---
Head Offsets | Trimming frames out of a segment's head | Negative
Head Offsets | Trimming frames into a segment's head | Positive
Tail Offsets | Trimming frames out of a segment's tail | Positive
Tail Offsets | Trimming frames into a segment's tail | Negative

For example, if you trim 10 frames out of a segment's head, the offset at the head of that segment is -10. If you trim 10 frames into a segment's head, the offset at the head of the segment is 10.
