Right but it looks like stretching the image on the top and bottom makes it much more pronounced.  I shoot 720p 60p in h.264 all the time and it's not nearly as bad.  I think fixing the stretching problem would be a better solution than increasing resolution a little bit.

I just recently used 48fps Raw at the full 16:9 res on a concert tour, in conjunction with 60fps h264, and I actually have some examples where the canon 720/60 shows pretty significant aliasing, and the raw/48 does not.

Not trying to disprove your claim, different scenario, different results. But I'll note I do remember one specific 720/60 clip that shows pretty heavy aliasing in a hat, and on most of the raw/48fps clips it wasn't there, or i didn't notice it.

I'll try to find some examples, as I'm pulling still frames now anyway.

On another note, I've been testing different aspect ratios with the 1.66 stretch factor. I haven't done any math but I think the 2.35 stretched is nearly 1.85. So I shot some stuff recently at 1.85 to see if it hits 16:9. That way you can get the maximum write speed with out throwing away any of the image.

Any one else played with this?

1. The mar 2 nightly already has the MLV snd module and even the earlier ones. TL has fps over ride in case you'll use crop mode. If not ML nightly is safe to use in 1X.

2. yes

3. I've tested it to be good when used with an external preamp/mixer and external mic. It can do 48khz as well as 44, 22, 11 and 8khz.

4. I'm using PC and the workflow is stable and reliable so far.

Thanks Ted, got everything worked out.

whipped this up real quick for a vimeo challenge:

komputerbay 1000x 32g, March 6th TL build.

Recorded in 2.35:1 (stretched 1.6 then cropped back to 2.35) max live view width, 48 fps, 1/96th shutter, iso 200, canon 50 1.4, variable ND.

Davinci > Filmconvert (IL FN FP) > Premiere/AE

sound was recorded on a  tascam dr-05 with the new little rode go mic.

Only issue to report is mlv sound didn't terminate recording properly once. Pretty sure it happened when i was in 720/60f in canon menus and at max live res/48f in ML menus and then recorded a crop with MLV sound on. Probably more of a forced error than anything, wasn't detrimental to the shoot at all.

thanks again.

Couple quick questions in preparation for a concert gig (tried searching but I couldn't find specific answers.):

1. Which 7D build is best to record sound with raw? Am I correct to assume the current ML build doesn't?

2. Can sound only be recorded with the MLV format?

3. Is it only usable as scratch audio?

4. I've used the raw_rec function in the past, as I'm on a mac and the mlv process on a mac was too complicated for my taste at the time. Have there been any updates to the mac MLV workflow?

Still searching, but thanks for the help ahead of time.

Actually it is something like 8 x 4 = 40 mm, because you can get maximum 3x in 7D's 5X mode, most if not all CF cards today cannot reach 3x continuously, but by a smaller aspect, you can get something like 2k, 5184 / 2000 = 2.592, 2.592 x 1.6 = 4.147, and 4.2 x 8 = 33.2 mm

But, 8mm is a fisheye, the widest non-fisheye is the 14mm full-frame lense, which I heard from rumor.

Actually the widest non-fisheye is the nikon 13mm that sells for like $10k, but that's neither here nor there.

Ive got the rokinon/samyang 8mm in the cine version. I know i've slapped it on to test out with raw, but the lens is very soft, so I might've chucked those clips.

I'll test it in crop mode and see how it fairs. I'd imagine it being even softer though. Not to mention it has zero depth of field.

Just a question for any of you Resolve 9 users out there. I used MLV2dng to convert my video. When I brought the dng file into Resolve it was all purple and really distorted not readable at all. What's with that ?

Only converter that has worked for me thus far in Resolve 9 is rawmagic.

I'm using resolve 10 now, though I haven't tested to see if any of the other converters work with it since the update.

As far as I can tell, all the bizarre fringing phenomena have seemingly disappeared, though the vertical line pattern is still apparent.

Grab rawmagic and convert the files again, see if that works. Im on a mac BTW, not sure if raw magic is PC compatible.

Some quick clips at a live performance filmed with one of the modules prior to the .fir one's:

graded in Resolve 10, no color fringing on edges. The lite version also allows you to output >1080 now which comes in handy for the 2k+ raw sequences. Still some dead pixels though.

figured i'd throw this on here to see what any devs working on the module think:

Sandisk 60mb/s card. I can get about 84 images consistently in 2.5k at 29.97. These two were 82, and 83, at 23.976.

Small hacks off (gave me a hack error?), Sjpeg, global draw off.

I guess that means it's somehow possible to trick it into 23.976 in crop mode, I'm not sure how I did it, but maybe this can some how help someone figure out fps override.

I will look into it. Can you try converting to legacy raw with mlv_dump and see if that works?

I'm on a mac, i tried mlv_dump through a VM but didn't have any success there either.

I think it's because I'm using OSX 10.7.5.

'Illegal instruction: 4' seems to be a terminal error where whatever tool your attempting to use isn't understood by the terminal, or something like that.

I could partition my drive and run osx 10.8 from it (with out having to pay) but I only wanna do that if it's a last resort.

Thanks for looking into it.
Anyone ever received this error message?

XXXX-iMac:~ username$ /Applications/mlv2dng /Users/username/Desktop/M26-0003.MLV

Is there an easy way to do that on a Mac? I found a program that uses the command line, but I was hoping there was something easier. I've been searching but haven't found the right .MLV thread.

Any more thoughts on this?

I just added the newest build today and am now getting the .MLVs. Formatted card in computer, then in camera, then made it bootable, and copied the autoexec and ml files.

EDIT: Tried MLV2DNG with no luck, now Im getting "illegal instruction: 4" in the terminal window.

XXXX-iMac:~ username$ /Applications/mlv2dng /Users/username/Desktop/M26-0003.MLV
Illegal instruction: 4

Anything I'm doing wrong?

Guys quick question; Just recently purchased Lee kit and graduated ND glass. Since RAW video shooting hopefully(!) will be stable on 7D as well, do I still need the Graduated ND glasses or could I recover every contrast details in the post (if I set the exposure for the whole frame) without being in need for a filter glass?

considering that ND glass is often used on high end digital cinema cameras that shoot raw, I would definitely still recommend using it.

I've shot in direct sunlight using raw, with out an nd filter and while the increased Dynamic range makes it more manageable than h264 it's still ideal to be able to completely control exposure. I shot a lot of F32 stuff and the lenses just aren't really designed to hold up in sharpness at that aperture at length.

I'm still experimenting with exposure, and achieving the best results through my workflow. I think ettr is a good method to follow. Though I've exposed to the shadows a couple times and gotten good results. It's really case by case basis.

I suppose that two serious issues with bootflag are:
1- "bootflag on" makes the camera much slower to start which is problematic when you want the camera to be quickly available for shooting.
2- Also, you can not easily get back your camera to the initial condition.

Am I right?

Put a non-ML card in and its 100% back to normal, or just remove the autoexec file and the ML file on your card, and reformat.

SUPPOSEDLY there's a small chance it can permanently brick your camera (either through overheating of the sensor, or a firmware lock up, or something else I don't fully comprehend,) but I know of no cases where this has happened.

You are correct about the start times though, it's probably only slower by a couple seconds though (which can be all the difference).

As far as I'm concerned the pros far outweigh the cons.

Quick test using the raw_rec module that freezes the live view.

All 60 fps, mostly 1280 x 344 but i think theres one or two that are 1600 x whatever the 2.37 aspect ratio height is.

Converted using raw magic, resized and graded in Resolve with a fuji film 3510 LUT to base off of, compiled in premiere, exported as 1280 x 720.

Here's another from about a week ago using the silent picture burst mode still and graded in ACR:

Sandisk 60 mb/s card
benchmarked at a max of 54 mb/s read and write speed.

@juanmelchor: Yes, it's just sad but the most recent version is not usable.

Walter I wouldn't call it totally unusable. While it is a pain to only be able to frame a shot, and not be able to track or follow focus, the current raw_rec module does record images to the card, and the images I've played with so far are pretty nice. Just frame a shot, hit record, capture as much as you think you can with out being able to see a live feed, end record, and then hit the menu button twice to unfreeze the display.

I'm uploading a test video with the current raw_rec build today, I'll post it here when I get around to it.

It's far from perfect, but I wouldn't discourage people from testing it. Especially since it seems we might not have a better build for a while.

Cheers, and thanks to everyone who has gotten it this far.
