Advice needed! Huge BMCC RAW DNG issue :/

[Tom Sefton]

Rick – I know, that’s why I said “for now”. I’m not complaining at all. The BMCC is the best camera we have ever owned and produces images only the F55, Red and arri can compete with. It’s just horses for courses and the BMCC has had higher frame rates requested for the last 9 months with no statement of intent from blackmagic. I don’t blame them-they are the sort of firm who will quietly go about their business and then unleash a camera that can do 120fps with 13 stops of DR for less than $5k. We got one of the first in the UK and have used it countless times and are still being impressed by it! : )

Fantastic if that is ever possible. I’d think 120 fps may not be I reachable if they continue to use the full active sensor area and downscale from that (which gives you the widest angle of view of course). I think many people would be happy to get 48 fps to 60 fps but would love 120 fps if it can be done in an affordable camera. As you say, they may quietly surprise us!

Are you going to pick up the BMPC4K? I’m just waiting to see informative footage and hear from those who get the camera in the first or second wave of shipments. I think that camera will be excellent for some purposes, including green screen and effects, and produce better looking 2K and HD deliverables, but people far wiser than I seem to feel the loss of a stop in dynamic range may deter from the image quality we’ve come to love from the BMCC. I think where motion is involved, the global shutter will show an improvement in image quality and that has to count for something.

I’m not so sure about the BMPC. I’d see more value in another BMCC as the upscaling from 2.5k is fine.

Future work might mean we need to go the RED route for now as we need something that is capable of higher frame rates, and something that can be framesynced in a stereoscopic rig…

Genlock support in the BMPC4K and the other BMD cameras is an omission that does exclude their use for many. Best of luck to you.

Hey Charles! I’ve surfing the web for a couple of days trying to find a solution to this issue.
I’ve got the same problem: can’t get DNGs working in Nuke.
I was ready to surrender when I found this topic.
Maybe you can give some me advice.
Thanks in advance.

Hello Charles,

Did you ever posted that tutorial on the workflow?

My situation is: I have the DNG RAW files from the BMCC. I do my Keying (blue screen in this case) in Adobe After Effects (latest version) and I need to find the best way to approach this.

When I did my keying tests I exported some Apple Pro Ress 1080p footage from Resolve and imported them into After Effects. These were of course just tests to see if our background plates would work and so on. Some of them came out great, and some of them not that great. However, this was 1080p footage.

I need to find the way to key the RAW footage to make sure I do not lose any quality.

Any help will be appreciated.

Merry Xmas 🙂
Pedro.

I know this is 4 years too late (!) but just in case anyone else is trawling the internet for solutions to keying bmcc/bmpcc RAW in AE I came across this tutorial:

https://www.youtube.com/watch?v=g7qFtzjt5uo

tell AE to import the dng files as footage and tick the “camera raw sequence” box and it’ll throw up the Adobe Camera Raw program – you can manipulate the RAW in there but having the profile (as with the tut above) is a massive help.

Being able to key RAW in AE without having to export to DNxHD has saved the loss of information, particularly noticeable on the edge of keys, that was plaguing my tests and reducing the key’s resolution.
