User guide

You can create a compatible video file using the following command: ffmpeg -i 'input.ext' -vcodec theora -vf scale=400:-1 -acodec libvorbis -ar 32000 "output.ogv" You can change the quality by using the -q:v flag.

The value can be any interger from 0-10 with 10 being the highest quality. The old 3DS has limited processing power and it is not recommended to use 10, but any value between 0 and 7 should be fine (4 is recommended).

You can also just set the bitrate manually using the -b:v flag. (Somewhere around 500k is recomended) You can place your generated videos in the /videos directory on your sd card, if it doesn't exist, create it.
