Does FFmpeg/WinFF remux or convert?

[Thunderhead2772]

i need a program that can remux avi to mp4, and i found ffmpeg, and WinFF as a GUI. but when i open WinFF it says "start Conversion"

by "conversion", does it actually re-encode, or does it mean it will just remux?

It(winff) will reconvert. I think you can adjust the ffmpeg command line with -acodec copy -vcodec copy so it doesn't reconvert.


Or manually use ffmpeg, ffmpeg -i video.avi -vcodec copy -acodec copy video.mp4

Or use a mp4 multiplexer like mymp4boxgui or yamb, under multiplex add the avi and output as a new mp4.
