Trimming features
Segments are re-encoded from your exact timecodes instead of snapping to keyframes, so cuts land where you set them.
Keep three highlights from a long video and get one merged file - segments are cut then concatenated automatically.
Watch the trimmed result in the page before downloading, with original and output sizes compared side by side.
