This ffmpeg setting can be use it in linux, too.

This is setting for myself from various sources especially maxconsole.net's PSP forum.
And this is setting specifically to 3GP Converter 0.34 with quite old ffmpeg for windows version.

I know there has a lot of good tools such as XViD4PSP, Videora but I prefer to using the 3G converter because it was most fastest and screen quality also good. I think reason is that my computer was quite old Pentium PC. So probably these new tools are more suitable for Core or 64bit CPU.


I found quite good example for linux.
I found it in Robert Swain's blog. But I couldn't test it so you can try out yourself.

* Thanks for the good info. to Robert Swan and you can find a lot of useful tips about x264's setting in his blog.
