I would like to know the exact process of the size
calculating. When I set the rip to one cd 700MB size,
the bitrate gets automatically calculated. When I start
the rip, the estimated filesize about the desired
700MB. To get the desired 0,17-0,2 Bits/Pix, I have to
set the scale to a lower value with lock aspect. When I
set this, and start the encoding, the estimated
filesize shows about the hlaf of the desired, ~350MB.

    i'm not sure what you're really getting at to be honest.
    what are the actual attributes of what you're encoding?
    width / height / length etc...

    the BPP value is derived from a fair few values you're able
    to control. if you double the file size value, and then
    double the video size, you'll come back to the same BPP, but
    a very different output....

    Hi!

    As a short question: Is the scaling (down) affects the bitrate
    at fixed filesize?
    If yes, how can I calculate it, because acidrip won't.

    Thanx

    I found a write about encoding tips, that gives answer and
    calculation for bpp and bitrate and others.

    I think acidrip should use these calculations.
