  1. Hi, there

    Whenever I put bit rate value "1600" in MeGUI or more Bitrate calculator, I got a very big file size something

    like 2 gigabits after encoding and of course not to make BPP less than 200

    in deblocking -3 -3, any idea to avoid that and to get a proper size? Thanks in advance

    Audio bitrate?
    Are you using 2-pass ?

  4. Bitrate is the number of bits per second (on average). If you specify an average of 1600kb per second for a 3 hour movie and then specify 1600kb per second for a 3 minute clip, it's a fair bet the 3 hour movie is going to result in a much larger file size.

    1600 x 3 hours = 2109MB plus audio
    1600 x 3 minutes = 35MB plus audio

    From the info you posted it appears your encode was 2 hours, 46min long and the bitrate was 1599kbps. Almost exactly what you asked for.
    If you want a particular file size, use AutoEncode, add the audio, and specify the size you want in the AutoEncode window. MeGUI will work out the required bitrate for you.

    Thanks man, for your concern, That's really helpful

    So lower the bitrate to get smaller size....
