Or choose them: MP4, MOV, WebM, MKV and M4V; they stay in your browser, even long ones
Volume
The sound is made 200% as loud; the loudest parts are clipped where they would go over the top, so raise it only as much as you need. The video is copied as it is (instant, the picture loses nothing), the sound written again.
Saved in the same kind of file as each video (MP4, MOV, WebM or MKV; others as MP4); a changed sound is written as AAC in MP4 and MOV, Opus in WebM and MKV. AVI, FLV and WMV aren't read.
