Ok, couple of things:

First of all, your write speeds are ok, but not great, and that could be part of the problem. Hopefully all of these write speed issues will start going away as soon as those new 1200X cards come to market.

Secondly, it sounds like you're shooting in crop mode, I haven't had particularly good results in crop mode. If you're shooting at standard 1920X1080 resolution, you probably shouldn't shoot in crop.

IMHO crop mode isn't particularly stable and I have gotten weird frames myself. I don't use crop mode unless I'm doing very short and very specific shots where I really need that extra magnification.

What resolution and frame rate are you shooting at?

Do you have Global Draw enabled? What about FPS Override?

Are you getting reasonably fast write speeds on your card?

Do the errors appear when you convert or import in specific apps? Have you tried different conversion/playback methods?

If you're "super anal" about quality, then this is what I would recommend:

Import .raw files into raw2dng or RAWMagic if you're on a Mac and convert to CinemaDNG image sequences.

Import CDNG files into DaVinci Resolve, export ProRes Proxy or LT for editing only.

Once you're done editing, bring XML back into Resolve, re-connect with the original CDNG files and do your color grading and final output from Resolve as ProRes HQ (you can do 4444, but I don't think it buys you a whole lot since one of those 4's is for the alpha channel).

If you want a step by step guide, there are tons on this very process in the appropriate Post Production Workflow forum.

Yes its an old build so forgive me for the noob question Im about to ask: Where can I get the  August 6th build and how would I install it since i already have magic lantern on the camera and cant remove it.

http://www.magiclantern.fm/forum/index.php?topic=6362.0

Just replace the files on the card.

ML is not doing anything. Canon firmware is obviously freeing up some buffer RAM when raw still photos are disabled.

I was recording at 1920 X 1080 with a Komputer Bay 64gb card with the 2.3 version May 18th build.

May 18th build? That's two months old. Shouldn't you be using something more recent, like August 6th perhaps (if not the current August 21st one)?

Lots of bugs have been fixed and some optimization has been implemented since May.

There are also some negatives about 1.2.1, for instance if you use 3rd party batteries, the camera will not display the remaining life of the battery correctly.
#584
I think the DCIM and MISC folders are automatically created when you insert the card in your camera....so I'd say don't worry if they're not there.

Raw Video / Re: Repair .RAW file

Yes, but you're going to have to do some footwork and search for the appropriate thread which has already answered your question. (hint. it's in the Post Production Workflow section).

Any chance of .mlv format being implemented with this?   ;D

Dan,

Even at this stage ML raw is highly bleeding edge stuff, so your desire for a reliable camera that you might be able to use even on commercial shoots should take the "alpha" nature of this hack in consideration.

Shooting at 30fps definitely stretches the capabilities of the card, I find that any resolution which requires above 90-ish mb/sec is potentially asking for trouble (and that assumes you have a good CF card).

If you're not shooting in Crop mode, I don't think you need to do an FPS override. Simply set up your Canon menu to shoot at 30fps and then ML should behave accordingly (I think). Most TV programming nowadays is 23.976 (except for news), so unless your client is specifically requesting your deliverables at 29.97, you might be just fine shooting at 24.

You haven't mentioned what version of ML you're running, but I can tell you that the August 6th version has been quite stable for me.

Also, is your CF card formatted as ExFAT? It might help if you do that.
#588
You have to read the Commits and keep up with various threads scattered around the ML boards to get a real sense of what's been changed on the latest version.

It can seem to be daunting, and quite honestly I just like to believe that with each new version they're making the code better and more efficient.

One of the new improvements with tonight's build should be the addition of DIGIC focus peaking which should be faster and more efficient for the CPU to handle (i.e. allow us to use it while recording without too many problems). I know that they've also been working on time code audio output, but I don't think it's been implemented yet.

Raw Video / Re: 5D Raw vs. Alexa vs. BMCC
August 20, 2013, 08:13:52 AM
No I don't mind ID-ing the cameras and you're spot on.

I ended up doing some power-window grading on the highlights on both the 5D and the BMCC. I was able to recover some information from the 5D (albeit with some haloing), while the BMCC doesn't have much to recover once you clip it.

In the low light test, I actually think we over-exposed the 5D and I bet I could get much more detail. The 5D was by far the cleanest in the low light test, with the BMCC being almost unusable (especially if you look at the full res Resolve file).

I'm a bit conflicted about the 5D3 honestly, image-wise it can achieve some gorgeous looking footage, but it's not the most production friendly workflow (no audio recording, difficult to monitor, and no real playback). The BMCC is the worst looking of the cameras to me, yet for the price it's probably the one which is most production ready.

Of course, if I could shoot with the Alexa all the time, that is one great looking camera.
#590
Yup, that happened to me with the OS X version of Raw2DNG.

First and last time I ever used that program.

Now I use RAWMagic for everything and it just works the way it's intended to.
#591
Not sure what you mean by "metadata" from Resolve. When you export from Resolve, you're processing the footage to have a certain look, no metadata included or required.

What you can do is either not color grade in Resolve at all and just export as flat as possible, and then add a basic grade in Premiere using something like the Fast Color Grade or other real-time plugin, or export your proxy footage with a certain look, do your edit, and then go back into Resolve and grade the final product.
#592
Also, ML doesn't work with 1.2.1

Are you shooting in Crop Mode?

What revision ML are you using?

Raw Video / Re: 5D Raw vs. Alexa vs. BMCC
August 18, 2013, 08:05:46 AM
I found that the Alexa and the 5D raw could probably cut together quite well. The 5D's dynamic range and the way it handles highlights isn't quite as polished as the Alexa, but if used as a B camera on certain types of shot, I don't think anyone would really spot any major discrepancies.

The biggest disappointment was the BMCC, it was noticeably softer and handled the highlights much worse than the other two cameras. I don't know if the 4K Blackmagic improves on this at all, my understanding is that the dynamic range on the new camera is more limited than the older one.

Raw Video / 5D Raw vs. Alexa vs. BMCC
August 18, 2013, 02:58:52 AM
I shot this test to see how the 3 cameras would do. I imagine a scenario where the main body of footage would be shot with an Alexa, while the BMCC or the 5D raw would be used on some shots. I wanted to see how these cameras would cut together and compare (not necessarily in quality, but overall visual continuity).



EDIT by SDX: use vimeo url with http:// instead of https:// ;)

We are two researchers (Patryk Stasieczek & Paolo Pennuti) at the Stereographic 3D Centre at Emily Carr University of Art + Design (Vancouver, Canada).

So you two are who we should blame for this? 



;D

Yes, audio has been disabled until it can be figured out how to maintain sync. Until then, it's pretty useless so the developers sought to disable it for the time being.
#598
Peter,

You are asking a great deal of newbee questions, nothing wrong with that. But perhaps you might consider reading up on a great deal of information that's already available.

Alternatively you might purchase Andrew Reid's book which should tell you a lot of things about shooting raw:

There is also this free guide:

Just wondering how many people have tried out this latest Aug 6th Build and know if it's better? Heard Aug 2nd version was a bit ropey.  Also a lot of people saying July 22nd was working nice.  Anyone have a download link to that version handy?  Thanks!

I just started testing the August 6 version. Seems fine so far, as a matter of fact I'd say more than fine since I've been able to record at 1920X1288 rather effortlessly (with Global Draw On and RAW enabled on my stills setting).

Raw Video Postprocessing / Re: Banding issues
August 16, 2013, 07:29:44 PM
Could be the application you're using to display the video? For instance in AE, you have to more up to 16 or 32bits. Banding can occur also if your monitor is not displaying enough bits (some monitors don't). I remember seeing heavy banding on some stuff I shot on the RED One a while back, and it turned out to be my monitor and when we played the same video on the color grading monitors the image looked fine.
