How do I estimate file size for a DVD video clip?

Czack Chiu December 10, 2012

For a 30 seconds clip in PAL DVD format (704×576, 25 fps, 24 bpp) with stereo sound in a sample rate of 48 kHz, how many bytes are needed?

I think it should be this – {704x576x24x25x30 + 48000×16(bits per sample)x2(stereo) } /1024 =7129500kb

But that seems way to big, can anyone help?

    Thats very hard to say but divide by 1024 and you should get the figure.

    I think that this website might help you:

    Nero Smart is a good a DVD making software. I have used it before, but not for a while. Other alternatives are a bit pricy or not so reliable.

    If they are right depends on the resolution quality of the sound and the video also weighed on the overall video hd videos weigh between 300 mb and 400mb

    It depends on lots of quality, frame rate, codec used, video length....there is no fixed formula.

    duration x bitrate = file size
    bitrate is the sum of audio and video bitrates
    adjust for bits/byte: 8 bits per byte

    Hard to say for me, but I can see that for a 30sec video the output size is simply too big!!!

    Divade by 1024 twice to gets kilobytes
