There are many bitrate calculators on the internet.
[EDIT] Kelly's numbers are correct.

I think you're off a bit there.

I get 4.55Mbps (leaving 0.2Mbps for audio would be 4.35Mbps for video). That's actually not very bad quality at all for uploads. It's almost DVD quality.

That aside, 235Mbps would be WAY higher than any usual encodes. At that rate you'd only get about 69 seconds in 2GB.

You're right as usual. I divided by 60 instead of 3600.

Sorry, I guess I'm still missing something. How do I use the calculators when I don't know how big the file is before rendering? I've recently come over from Pinnacle Studio and the only thing I miss about that program was this feature. I could choose different settings for file quality and it told me how large the file would be.

Please forgive the basic questions.

Thanks

ajlach,
some of the Make Movie options give you an estimated size.

That's what the bitrate calculator is for, it will tell you how big the file will be based on a formula of (in simple terms) length of video x bitrate = file size.

But as mentioned, VMS should give you an estimated file size before rendering.

Time (seconds) x Total Average Bitrate (Mbps) x .125 = File Size (MB)

Note that audio bitrate is included in total ABR ;?)
