Subclips
Adjust media start and end times of a subclip
Select the subclip in the Project panel.
Choose Clip > Edit Subclip.
Edit the Subclip Start and End timecode fields.
Note:
If you have an instance of a subclip, you can shorten the subclip to only the In and Out points of that instance. This limit prevents losing frames that are used in the sequence.
