Here is my set up.
Davinci Resolve Lite 10 (free download). I'm still getting my head around Resolve but I can already see the potential power of it.
Euphonix MC Color controller compatible with Resolve, Avid MC and more. Not essential but after using one you will struggle to go without.
Canon 5D mk3 with Varavon LCD viewfinder
Screen grab of Magic Lantern firmware RAW video page. The firmware is copied to the SD card so it runs in conjunction with the standard canon firmware. I haven't had any freezes nor over-heating.
I will shoot some test footage this weekend so stay tuned!
