Videos that are encoded with the MPE file extension are using the MPEG-2 compression algorithm with progressive video formats sampling at about 1.5million bits per second. See MPEG movie files for more information.

Very high accuracy transcription with noisy tapes / accents. The ability to edit as you listen is incredible. I haven't been impressed with code to this extent sin...
