Frequently Asked Questions
Does trimming re-encode the video?
By default we use stream copy (no re-encode) for fast trimming. Enable 'Re-encode for accuracy' for frame-accurate cuts.
What formats can I trim?
MP4, MOV, MKV, AVI, WebM and most common video formats are supported.
Will I lose quality when trimming?
With stream copy mode, there is zero quality loss. Re-encode mode may reduce quality slightly but gives more accurate cut points.
