I am looking to pull the trigger on a 5d III if it truly can produce a stable RAW 1280 x 720 at 30fps with no dropped frames
If it is possible with the current Magic Lantern build can anybody tell me how many mins that would record on a 64gb 1000x card
Thanks for any advice
No sweat! At 1280x720 29.97 fps you will require a card speed of 46 MB/s something like 22 minutes in 64gb
I think it can reach 1728x972 or maybe 1856x1044 in theory (needs to be confirmed though).

I get 1728x972 continuous. 1856x1056 get dropped frames after 400 frames.
Yes, I agree no sweat even for slower cf cards-- looks awesome! Thanks ML TEAM! I'm stoked!
I found that the SanDisk ExtremePro 90mbs card will even do full 1920x1080 without a skip!
Just for the record.. 1856x1004 at 30 fps recorded 23.5 GB before it skipped one frame.
Setup:
Lexar Professional 1000X 32 GB
Framing Force Left
Preview: Hacked
Memory hack: ON (six buffers)
Not crazy about frozen live view Hacked Preview (not practical for me). But the new memory hack option is a nice help imo. See https://bitbucket.org/hudson/magic-lantern/commits/6397e112ed41d36795b18c8825ab50a258811f2e#general-comments (https://bitbucket.org/hudson/magic-lantern/commits/6397e112ed41d36795b18c8825ab50a258811f2e#general-comments)
By expanding the buffer memory available, I was able to do full 1920x1080, 30p for about 12 seconds. Doesn't sound like much, but for many situations, 12 second takes are sufficient. Without the new hack, I get only about 5 seconds. A couple more memory finds like this and full hd at 30p might be possible for much longer takes. I love 30p for creating subtle slow motion for music videos. The hack also will make huge difference for any other borderline resolutions.
Thanks you all for the info looks like I will be joining the party !
Does it stretch the image at this resolution or is it a true 1280 x 720
Thanks ML team we all really appreciate what you have done !!!

No stretch required. Stretching the image is only required when in Canon 50/60p mode (1x).
thanks for the info platu
