Chart for Calculating File Sizes MP3, MP4, FLV etc...

Have been all over google and various video / audio sites.

Can anyone recommend a chart or calculator that shows all types of Audio / Video file formats and their corresponding bandwidth? i.e.

5 minute MP3 at 320kbps = x Mb
10 minute FLV (youtube) = x Mb

Might be a good sticky considering that a resource is hidden on the net

I don't have a great answer for you, but the rule of thumb is that

.WAV or .AIFF audio is 10 Megs for every minute.*
128 kpbs stereo MP3 is 1 Meg for every minute.

So using 10 or 1 you can quickly multiply to get an estimate.
Can I ask what brought this up?

*that is for 16-bit, 44.1 kHz

Beyond Basics

Yes, that is pretty basic. Im looking for some resource that has video files and audio files.

Say a spreadsheet with FLV, AVI, MP3, WAV, OGG, MP4 1080, MP4 720 etc. etc...

This would be helpfull for calculating bandwidth requirements and HD space

The problem is that the algorithms you mention are lossy and so don't have a 1:1 correlation to input files, and are also PROGRAM DEPENDENT in their results and so compression will give different sizes for different source files even with the same settings. The best you can do is rough guesstimates based on averages or worst case scenarios.
