Video Trimmer — Frame-Accurate Cuts, On-Device

Cutting a 26.5-second segment out of a 55-second capture

The Video Trimmer cuts an exact segment out of a clip by re-encoding your chosen range, so the boundaries land exactly where you set them. A tester sent me a 55-second bug-report capture where the actual crash happened between 12.0 and 38.5 seconds. I typed those two numbers in — end minus start makes a 26.5-second clip — ran the cut, and the download was precisely that window: no leading seconds of me scrolling, no trailing coffee break. Frame-accurate beats keyframe-snapped, every single time.

The re-encode is what buys that precision, and it carries one tradeoff: output is a fresh H.264/AAC encode rather than a byte-for-byte copy, so don't promote a trimmed clip to your archival master — keep the source for that. Times are plain seconds and decimals work: 90 means 1:30, 12.5 means twelve and a half seconds in. The end value has to be larger than the start or the tool simply refuses to run, which has saved me from more empty exports than I'd like to admit. For sharing, the MP4 result goes straight into chat or email without a second thought.
