[FFmpeg-user] how to convert one mp4 file into multiple files with different setting

[qw]

Hi,


I want to use ffmpeg to do the following complicated task:


I have one mp4 file with one audio and one video stream. I want to convert the mp4 file into three encoding settings, and then save each output with one encoding setting into 3 files.


How to do it by using single ffmpeg command?


Thanks!


Regards


Andrew
