A nice bitrate calculator?

When I calculated the bitrate with the calculator on this site, and then encoded the movie (mpv) and audio (mp2) , the output was only like 4 gb in size when i authored them in DVDMaestro (and a DVD is 4.37GB). Is there any bitrate caluculator that is more exact?
FitCD doen't seem to work because it can't calculate DVD bitrate.

For DVD, The "PowerBIT v1.4 Bitrate Calculator" is the easiest and best, imo. It may not have as many features as some others (FitCD, etc). It should also work for SVCD.

Just enter the length of the movie in minutes, how many audio tracks and their bitrates, the size of any extras, and the destination disc size, press "calculate" and you get an exact answer which can be used as a CBR value, or an average value for any VBR encoding.

Very simple and easy.

I used to have the same problem. Although I mainly use this method for encoding my own home movies and such, the formula that works best for me is: Divide 598533 by the total length of the movie or files you want to fit on a standard blank DVD. This will give you the exact bitrate which will fill the dics completely. This doesn't take into consideration any addition soundtracks or extras however because as I said I usually use this for home movies but it does make use of the entire disc based on the resulting bitrate.


Example; 598533 divided by 120(minutes-a full blank DVD)=4987.775.
I would encode using 4987 as the average VBR.

Good luck
