Frequently asked questions
What time format should I use?
Use HH:MM:SS, for example 00:01:30 for one minute thirty seconds in.
Will trimming reduce quality?
No. Trimming uses stream copy rather than re-encoding, so the kept portion is identical in quality to the source.
Can the cut point land exactly on any frame?
Fast stream-copy trimming may snap to the nearest keyframe rather than an exact frame. For most clips the difference is a fraction of a second.
