I just want to convert my mkv video to mp4 video with using preset ipod320 and vcodec libx264, what did i miss out and how should my command be? Thanks!

What should i do

[Carl Eugen Hoyos]

From a quick look, the following presets exist:
ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow, placebo

The libx264-ipod preset should still be available as an non-standard libx264 preset. Replace "-preset ipod320" with "-vpre libx264-ipod320". Windows users may have to use "-fpre" instead however, with a full path to the preset file which is called "libx264-ipod320.ffpreset".

Alternatively you could probably just use:
ffmpeg -i input -vcodec libx264 -preset medium -crf 23 -vprofile baseline -level 13 output
