Howdy, this will sound stupid but . . . .

What is the math behind figuring out how big an MPEG2 will become from an AVI? ie, bit rate, one pass, etc?

I have some AVI that I want to convert to MPEG2s and keep them about 1.1 gbs each (44 minute AVIs -- about 350 Megs). What sort of setting should I use?

Hope some one can help the green newbie.

Regards,
Fallon

Put it simply - bitrate.

For example, if the combined bitrate of video and sound is 500kbit/sec for example, then a one minute video at that bitrate would be about 3.7MB (don't forget the difference between kilobytes and kilobits - there are 8 bits to a byte)

If I've done my maths right, then you want to look at a bitrate of approximately 3,600kbit/s for 1.1 Gigabytes for 44 minutes.

Let us know how you get on, I'd be interested to know if I'm right

Actually, not sure if i've worked that out correctly. Still, try it and let me know anyway!
