I found this very useful program called Media Converter 2, that is very useful to convert videos for to play on the N810.
I converted Cromartie High School for the trip I’m going on this morning. I used N810 High settings, 2 passes and audio gain.
Before I started encoding I needed to extract the subtitles from the MKV files, cause the program doesn’t include them automatically unless they are in the folder where your source file is and are called the same as the source, just with the extension .srt. I extracted the subs with mkvextractgui which is a very nice little application, for extracting video, subtitles and audio from MKV files.
The end result is pretty good, playable in Canola2, I don’t complain and I’m going to laugh so much in the train.
