Bitrate Calculator for Magic Lantern Raw Video
« on: March 05, 2015, 11:09:29 PM »
Hi,

I made myself an Excel spreadsheet that calculates RAW bitrates and recording times for various card capacities, so I thought I'd share it:

https://www.dropbox.com/s/o7hmgc726p59vke/Bitrate%20Calculator%203.xls?dl=0

Mainly you would be plugging numbers in A3, B3 and C3.

Please let me know if you have any ideas for improvements.

I just updated it so that if you change the color depth (which you probably wouldn't normally do) it will plug into the formula (I had it hard-coded to "14" before).

Hey Frank,

Are you handy with a compiler? Would you consider making it a module?

I put a module out recently that presents some menus, does some math, and shows the results at

http://www.magiclantern.fm/forum/index.php?topic=17874.0

It seems the pattern could be adapted to a bitrate calculator.

Regards.

Hi ewinemiller,

I don't have experience doing that sort of thing, but if someone who does wants to try I would be glad to explain any of the formulas that aren't clear from the spreadsheet. The math isn't complicated.
