Final encoded file size calculation

[srfscenar]

Hi all.

Is there a math type or any other way to calculate the size of the encoded file from cinevision?

How do the compressionists know what the output file will be in GB's?

There has to be an accurate way and not spend hours or days for encoding and then realize it does not fit for some MB's!

Any help is appreciated!

Thanks.

Yup, use the bitrate calculator found in MeGUI. Simply enter the amount of frames and select your audio file, then enter a size and you will see the maximum bitrate you can use for that size (take 1 Mbps off to make sure you're not getting an oversized disc).

Thanks iJohn.
But I do not see an option whether the file will be in MPEG-2, AVC or VC-1. Shouldn't that be a major factor?

It seems like a nice calculator but not for what I need it for. Unless there is something I didn't see.

Hm yea, I just noticed it only support the x264, xvid and Huffyuv codecs. I don't know of there is much difference between MPEG-2, AVC or VC-1 codecs, but isn't AVC the default codec used in Cinevision for encoding? Then you can just use the x264 option in the MeGUI bitrate calculator. Anyway, this tool is of course not 100% accurate, thats why I take a Mbps off the total bitrate to prevent an oversize.
