    Hello, running a very old (stone age) 700MHz G4 eMac. Takes forever to encode an episode of 24 to h.264 with the new Handbrake "AppleTV preset" and 2-pass.

    I would like to use the AppleTV preset so when (if) I ever decide to get an AppleTV the files will look good and I won't have to redo them again. (future-proof)

    Is 2-pass necessary if you are using h.264 (I've heard it's higher quality than regular mpeg)?

    I can see that the file I tried will not play on my machine under Quicktime very well (slow response) and it displays a bad picture with VLC. (VLC says frames are dropping, computer too slow?)
    Can someone explain in simple terms what video bitrate is? Why is it 2500 for AppleTV?
    Does anyone have any idea what the highest bitrate an eMac can display is?
    I have been using the base settings for the older handbrake version, which is 1000 bitrate and it runs fine on my machine. My main question is, what do you gain with a higher bitrate?

    I would like to get a new Mac so much, but money's real tight, maybe I could get a cheap G4 mac mini, anyone know where?

    higher bitrate gives more data per time to display, of course, more data means more details about the graphic.
    1000kbps is good enough
    encoding H.264 is intrinsic slow, at least for now
