How to Record 4K in Magic Latern With Cannon EOS 5DIII

[gundam254]

Hi there, I got a 5D III and magic latern 1.1.3. I tried getting more than 1920, but it wouldn't let me. The highest resolution that I can see is 3520, but it wouldn't let me  choose that option saying won't working in current mode. There's no 4k too.  I tried the fastest CF I can find which are Lexar and Sandisk at 160MB/s. I even tried the 1.2.3. Both of them didn't work. Does anyone know why? There are news and people mention that it is capable of recording 4k. I can't find a tutorial that actually teaches how to record 4K. Please let me know. Thanks.

Download the build here under "4K raw video recording; lossless compression"

Canon 700D can record 4K also .
