    i have alot of HD & bluray content. I'm just confused how after i convert with visualhub, that all my files are 3.75 gb. Some movies being 3 hrs, some 2, some less.

    Seems like there would be a quality loss there.

    How do i get the best possible quality with visualhub? i use "go nuts" and Apple TV setting. 1280x720 picture.

    please help.

    Make sure that under 'advanced' you haven't selected to 'fit each video' into a particular size file.

    Perhaps you should have titled it "How to transcode MKV HD to an Apple TV format with Visual Hub". The syntax of your current title suggests you're trying to play MKV on an ATV.

    not sure, but maybe all your file sizes are 3.75 gb because the ATV and iTunes has a 4gb limit for movies. and if your using a ATV preset this is deemed it safest/largest file size!

    i think if didn't use the preset all your files would be over 4gb, various sizes and unplayable on the ATV and on iTunes.

    Edit: Just found out that the 4gb limit is kinda old hat for the ATV and iTunes, so maybe its an old version of visual hub, or maybe they haven't updated the program yet.

    like i said not sure as i have never used visual hub, but hope this helps a little.

    I think with the "go Nuts" setting you ARE getting the best you can out of Visual Hub. You're converting full HD to the 720p that ATV can support. So I suspect the VH gives you the best compression it can within whatever the file size limits are.

    Probably. With a two pass encode, the program is figuring out where to put most of it's effort. It'll put more of the processing power into fast motion sequences and less into the static scenes. That way, the the scenes that need more attention get it, and the the bit rate is averaged over the entire movie.
