[H-GEN] command to convert a video file to mp4 format

[David Harrison]

Try:

ffmpeg -threads [NUMTHREADS] -y -preset slow -i [SOURCEFILE] -s 640x360 -r
25 -b 600K -ab 96K -strict experimental [DESTFILE]

(Customise resolution, framerate, bitrate and audio bitrate to suit.)

I'm using this now with a semi-recent build of ffmepg, so depending on what
era your binary was released it might just magically work. Unfortunately
they seem to change command line options regularly.

Another poster suggested Handbrake; it has a good CLI mode and is basically
just a wrapper around ffmpeg/x264 - it will simplify a lot of encodes if
you don't mind installing another application.
