Hi everyone,

I am having a lot of trouble with this dual ISO in raw video. I was wondering if anyone knew the solution!

I'm shooting a 5DmkIII with nightly Build 2015Dec20.5D3123. Shooting .MLV. (Non-lite, and not .RAW)

I am processing using raw2cdng.1.7.5 to turn MLVs into DNGs, and then cr2hdr (downloaded off the ML downloads page) to "process" the dual ISO to get rid of banding. Exiftool.exe and dcraw.exe are in the path.

Before processing, the DNGs look banded as they should:



But after cr2hdr is done with them, why are they turning out like this:



The directory they're in looks like this now:



Thank you!

Raw Video / 5D Mark 2 - Crop Mode? Digital Dolly?
« on: March 24, 2014, 11:16:36 PM »
Hey all, been experimenting with RAW video on a 5D Mark 2 and ML, however some things don't seem to work.

Crop Mode = When I try to zoom in 10x, it records a file that ends up looking like a seizure:


Recording in crop mode also only lets me record for 8 seconds before it "stops automagically".

As for digital dolly, how do I get it to work? I activated it in the ML menu, however when I use the joystick in crop mode and try to move the shot around, nothing happens. What gives?

Thanks!

Raw Video / mlv_rec vs raw_rec
« on: December 25, 2013, 08:20:47 PM »
Is there a comprehensive guide somewhere with the exact differences between the two?

Also I just tried shooting mlv_rec, but it leaves me with MLV files that I don't know how to process. I tried running searches but nothing really came up...

Thank you and Merry Christmas!

Ok so let's face it, the RAW video is amazing, thank you ML team for this groundbreaking feature and all your hard work to get to it.

I really appreciate the increased sharpness and detail, noise performance, and dynamic range over H.264. However the instability, file sizes, and max resolutions not so much. Don't get me wrong, these are completely understandable given what it's trying to accomplish, I'm not asking for a magical fix on those. Thing is, right now we have the two polar ends of the scale. A really bad stock codec, and then the highest of qualities of one. I feel like a lot of us would be happy with a healthy compromise option.

What do I mean by that? What if we didn't have RAW, but instead had JPEG instead or something similar. 1/3 of the file sizes, so the camera, global draw, etc. would not have to work as hard. More stability, less storage space required, not as speedy cards required, and yet retains all of the detail image quality and sharpness of RAW. Yes we lose a lot on dynamic range, but think of it as basically a higher quality codec, a step up from H.264, the only difference from RAW being that 14-bit colour depth, everything else the same. Basically the ONLY change being the format of capture. Instead of RAW, it's JPEG.

Is this possible? I think this would be an amazing feature, and very usable as well. This might allow for non-H.264 true 1080p on the 5D Mark II (which isn't possible now) since it doesn't have to work as hard, as well as perhaps higher frame rates? I also feel like it would be possible because if you can get 24p RAW working, shouldn't it be easier/ a step down to get JPEG working the same way? I don't know, so if I'm wrong, let me know of course.

Thank you!

Raw Video / 5D Mk 2 Raw + HDMI External Monitor: Continuous Recording?
« on: December 05, 2013, 04:22:49 PM »
Hi everyone,

I am thinking of getting an external monitor for my newly acquired 5D Mk2. However the main concern I have is about the camera not being powerful enough. Even without a monitor, I find RAW stops recording after 4 or so seconds if I even have focus peaking on, no matter how fast the card is (I'm using 1050x 64GB Komputerbay) simply because the camera's capability is the bottleneck.

So my question is twofold:

1.) Will I be able to record continuously with zero dropped frames at 24fps (23.976) in RAW while having an HDMI monitor plugged in? I'd also like to have Live-DIGIC peaking on, which doesn't take as much from global draw as regular focus peaking. Or can the 5D Mk 2 not handle that?

2.) If yes, which monitor should I get? I'm looking for something hotshoe mountable, 5" or 7", cheapest possible, preferably under $150. I've been looking at some Lilliputs but I don't know which one to get.

Please assume shooting 14-bit RAW 2.35:1, 23.976 fps at 1872x796, on a Komputerbay 64GB 1050x Card.

Thank you!

Raw Video / Fixing random colour strips across DNGs?
« on: November 24, 2013, 10:12:07 AM »
Hi everyone,

I tried shooting RAW with my recently acquired 5D Mark 2, the problem is that some frames from my DNGs have strange pink bands going across them.

Shooting 14-bit RAW 2.35:1 at 1872x796, Komputerbay 64GB 1050x Card, November 1st Nightly Build I believe. Unpacked through a few methods, including raw2dng.exe

Here is a sample of a DNG and what it's supposed to look like:




If anyone knows the solution to this, I'd greatly appreciate it. Thank you!
