Battle testing the
10-12bit broken 3xcrop5D2212 LVState-wip branch from dfort , to see what bricks it . As we know the
write channel I'm using (0x2)has a very small amount of data being written to as a1ex said .
We do know that this build breaks 3x Crop_mode , hence the name . HDMI does not brick it , connected at bootup & after ml running plugged it in & no problems , thou the liveview was slow almost seems to running a half speed (18-12fps) once recording started liveview returned to normal speed (no delay)(without HDMI connected) (D4/5D2 kills the ml overlays with full mlv+audio , clean output recordable) , did notice to 10x zoom the black levels was bad (pink-ish normally is canon liveview) 5X zoom or 3X Crop mode was normal .
Frame override was enable to 23.976 , so no problems there -- audio was enable to 44.1 kHz , no problems again . The only issue I had that cause a lockup/frozen liveview (needed a battery pull) when I changed the ISO I always use analog pure ISO 100 , 200 , 400 & sometimes 800 not digital pushed or pulled and when I move the dial to change ISO I landed on a digital one (320) & it locked up

quick battery pull and I was back in business . I could reproduce the lockup at every digital ISO , the pure ISO's all work without lockup up to 1600 ISO (yes it pure also , found that out in my disassembly) . After I got the right ISO (200) I proceeded to set to 12bit @ 1856x1044+audio , started to record a 7+ min talking head , 30GB had a skipped frame at 11299 frames so it stop , I was done just before that by a few seconds . It was a perfect recoding no corruption , the 1st frame had out of sync image bit the rest are all good (perfect) . I didn't use 10bit , thou I did test it and not problems other then the digital ISO thing , I find there's more noise
then I like (I filmed in doors with less then desirable light conditions ) so shadow get noisy when pushed in post.
What does all this mean , not sure but it is usable , but then again it could blowup and you get to kept all the parts
If anyone want's to use it for a project you must test test test & hope doesn't it lockup (more then likely it would be ok) but
Great Caution must be Observed
