Stream copy — video and audio are repackaged as-is, not re-encoded, so this takes seconds regardless of file length. On a file whose codec can't legally live inside the chosen container (for example, a WEBM's VP9/Opus going into MP4 or MOV), Remux Studio automatically falls back to a full re-encode instead of just failing — but that re-encode needs much more memory and can fail on longer or larger files. WEBM sources only truly stream-copy into MKV — pick MKV for an instant, reliable conversion.
Encodes with H.264 video + AAC audio in an MP4 container — the most broadly compatible combination for sharing and playback.
