Cut a section out by time. Fast mode finishes in seconds because nothing is re-encoded.

Settings
Fast or exact?
Fast copies the existing video stream instead of re-encoding it. It finishes almost instantly and loses nothing, but it can only cut on a keyframe, so the real start can land up to a few seconds before the time you typed.
Exact re-encodes the section, so the cut lands on the exact frame you asked for. It takes as long as any other encode and loses a small amount of quality, the same as any re-encode does.
Use fast for chopping a long recording into rough sections. Use exact when the first frame matters, like a clip for social media.
Time format
Type 1:30 for ninety seconds, or 0:01:30.5 for hours, minutes, seconds and a fraction. Leave the end time blank to run to the end of the file.
Common questions
Why does the fast cut start early?
Compressed video only has full pictures every few seconds; the frames in between are stored as differences. Without re-encoding, the cut has to start at one of those full frames.
Can I cut out the middle and join the ends?
Not in one pass here. Trim each side separately, then run both pieces through the merge tool.
Does trimming lose quality?
Fast mode loses nothing at all, it copies the original bytes. Exact mode re-encodes, so it loses a little.
