Upon further testing..

Regarding point 2

It is now possible to do zoom 5X and get full color if Global Draw is turned OFF!! This is awesome!

By using snap points as previously described one can flip from center point to crop mode (off to the left and up) focusing box. If you do this then the 5X and the 10X zoom remained focusing at the same area and thus framing and focusing works better.

Regarding point 3.

If I test with video where speed is marginal and video quits due to drop frames, the results are sometimes better with Hack3D but sometimes not. Something else is going on. When it works it really makes a difference something like going from 200 frames to 600 frames.

It's fixed pattern noise, it's always been there you just couldn't see it before. Set the denoiser sliders to 50 or to taste.

I was actually trying to test out my CF cards yesterday. On my Transcend 64GB 1000x card, on the May 17th build I couldn't get past 78.1 MBs so I got dropped frames at 1920x1080. I went back to the original May12th build and I could again record 1920x1080 at 81 MBs with no dropped frames.

However a funny thing happened. After looking at my video files, I found out that I was recording BOTH H.264 internal and RAW to the CF card. I guess with the May 12th build, you have to go into the menu to start recording. I must have forgotten that the start/stop button didn't start RAW, but I hit it and the H.264 started. My H.264 clip is actually something like 5min long, but I started and stopped RAW recording from within the menu. So I have exact matching video files of H.264 and RAW. I have them in my video, and I also graded the H.264 to see the differences. The RAW recording is choppy, probably because of dropped frames and recording both types of files.

Take a look and tell me what you guys think:

Test of the 5x Zoom Mode:

May 17th Build, Transcend 64GB 1000x CF card, 81 MBs, 1920x1080, no dropped frames.

This is not a problem. You must use the Denoiser

Hi Guys sorry to butt in on this tread but i am having no luck getting my 5D Mark3 to actually record raw. The firmware seems to load fine but I don't have any of the menu options for frame rate override or Raw recording or anything like that. I am trying to do a test with Dave Stump on monday he an ASC Cinematographer and is the Head of Technology for the Academy of motion Picture. He has heard of this amazing new firmware and wants to see it working. Is there anyone that can help me figure this out for Monday?
Do I have to pay something for the right firmware i got it from the Magic Lantern web site and my camera even says that its the APLA 3 version etc. Please help ! Again sorry to butt it on this thread.

You have to load the module and then it will pop up. Make sure you have the latest build which you can find here

thanks i have bought neat video some time ago and its a great denoiser, but when i take a photo.. there are no vertical lines?
i thought when i shoot raw, its the same as making 24pics/sec.

so why are there such vertical lines.
perhaps anyone can explain in detail.. ? perhaps there is a possibility to avoid those lines.
(i shoot in 1280x720 at the moment cause i have only a 600x cf card.

Thanks buddy, but
In my videos, it looks more like banding noise which should only occur in high iso settings.
I know grain from high iso rates- but im talking about noise which is also seen in low iso shoots.. Strange

squig · « **Reply #38 on:** May 19, 2013, 12:11:26 PM »

it's visible in every ISO setting just more so at high ISOs. Shoot with your lens/body cap on and push the file 3-4 stops in post and you can see for yourself. It's less noticeable with H.264 because of the compression and noise reduction. It's easy to remove in adobe camera raw without screwing up your IQ.

Also get this at ISO 100 in shadow areas if exposure has to raised. May want to shoot ETR (exposure to the right).

Have shot with correct exposures.. Hope that my camera sensor is not damaged..

Hello everyone, yesterday analyzing the dng file after conversion with raw2dng and comparing them with raw files taken with the same settings and lighting, I realized that working them in lightroom appear compression artifacts .. I do not know if developers ml if they are noticed .... I am attaching a 'picture .. or lowered the value of clarity .... https://dl.dropboxusercontent.com/u/71964196/CR2vsDNG.jpg

jakdaniel1975 · « **Reply #42 on:** May 19, 2013, 03:24:25 PM »

point out another flaw I see often ... attaching the photo inside the red circle in many frames I see this ... https://dl.dropboxusercontent.com/u/71964196/dng.jpg

squig · « **Reply #43 on:** May 19, 2013, 03:44:31 PM »

If you have frames with any errors please post the actual DNG file and what ML build you shot it with.

jakdaniel1975 · « **Reply #44 on:** May 19, 2013, 04:06:07 PM »

Here are some files where you see the flaw shot with 5d mk3 ....

thank you very much for your great job!

Set the resolution 1920x1080 24p in the Canon menu and whatever your card can manage in the ML menu. If the problem persists update the ML firmware to a newer build.

jakdaniel1975 · « **Reply #49 on:** May 19, 2013, 05:12:16 PM »

could you please tell me where to download the latest firmware currently available? thanks
