what MediaCoder does not do

MediaCoder does not work with DRM'd content. remove the DRM first.

Video Conversion with MediaCoder

it's not simple. there will be a lot of trial and error getting your file conversion to work. and you may uncover some bugs in MediaCoder (like I did). MediaCoder is continually being updated and fixed.

MediaCoder can be an error-prone process, and daunting. MediaCoder is a complicated, not-easy, powerful, and flexible conversion program. but keep trying to do your task. you will get it eventually, and learn some things about mediacoder in the process.

note that the input audio rate is 8000Hz PCM, which is 64kbps. in order to encode without errors, I had to choose 128Kbps.

your mileage may vary!

the settings I listed above were for my Nikon P90 camera's video mode. it uses PCM audio in an AVI file format. you may have a DivX in an AVI file format for some cameras. so your mileage may vary, and you may have a different audio "in" format, so you will need to change the audio source settings.

the beta version is nicer, but has a serious file loading bug. if you load a file, sometimes it will not load completely (and it's visible too). If that happens, just reload the file. It is, after all, a beta version. if you don't want to mess with that, just use the stable version 1.26.
