    Hope there's an easy answer to this :p. Usually I use handbrake for my encodes, but Handbrake doesn't do video passthrough. I'm therefore hoping that someone here might know the answer.

    I use MakeMKV to rip my blu-ray films. What I was wondering is how I can convert blu-ray movies to a quicktime compatible mp4 file without compressing the video. In ohter words passthrough. What I was thinking was this:

    1) Rip the movie using MakeMKV
    2) Demux the mkv.
    3) Convert the audio file to a compatible format (for example AAC)
    4) Use a program to mux the audio back with the untouched video file into an mp4 container.

    The problem I'm currently having is figuring out what program to use for remuxing the video and audio file into an mp4 container. Any ideas?

    The Apple TV cannot do video passthrough. Its output are all post decoding.

    Subler can remux an mkv into an mp4.

    The video file in the .mkv would have to be H.264 to work with Subler and be playable with AppleTV when muxed into a .mp4 container.

    So if your Blu-Ray has a VC-1 or MPEG-2 stream you're out of luck. At least that's been the problem in my case.

    The video was most definately H.264. I checked before I tried it. I'll try a different video when I get back home from work.

    Perian should do it, There's a GUI for MKVextract (called MKVextract) here. I've only used it once, quite some time ago, so I can't guarantee anything, but it's worth trying.

    The video is most likely 1080p, high profile, has bitrate over 6-7mbit/s etc etc. Those are not going to work on your ATV, it's just not powerfull enough (no, boxee or perian can't do it either).
