This Perl script will convert all the contents of a folder to x264/neroaac mp4 files.
The script is made to handle batch conversion for the PSP, but is quite easy to setup as a general use converter.
Subtitles can be hard subbed to video from mkv containers, good for anime.
Technically its not a GUI, but where else would I put it.
I know that there are other batch converters out there, but I am too lazy to throw 100 files into a converter manually.
Useage : batchdirectory.pl <storedir> <convertdir> ...
Pretty simple.
