Workflow: Working with DNG ....what are the options ?

Since this is a workflow topic, I'm putting out my curiosity...

With RED, I've always wanted to shoot to the SSDs, and have an external HD-SDI recording simultaneously for immediate dailies/proxies to cut with.

The question is if the Magic Cam's 3G-SDI link sends over ALL of the metadata and what recorder can read and store it. In this case, the recorder's ProRes or DNxHD proxies have whatever LUT's applied already on them, you take those and cut with them, then XML back to Resolve to finish, back out for a 2.5K master.

Dump the Proxies after the project is done. The trade-off's buying, attaching, and powering one more piece to the puzzle but not having to wait to render out material to edit.

Based on second hand info, my understanding was the the 3G-SDI link was for monitoring only. The thunderbolt output would have the properly debayered output.
 
Just tried to load some 12bit CineDNX files into Premiere - doesn´t work. There is an importer plugin from Adobe, but it also acts up.
After Effects eats the CineDNX single frames and the MFX version just fine.
If you load the single frames (click on the first frame only) a window that looks like the Photoshop RAW importer pops up and you can do 1stLight corrections.

You could now create proxie files from this or just import the AE project in Premiere.
Still a bit slow and awkward, but technically it works.

I hope Premiere CS6 can handle the files natively though, so we can skip the AE processing.

On the other hand, I expect 80% of the BMCC users gonna record in ProRes anyway, so you just can drop the material on the timeline and start editing.

Cineform has tool for batch convert DNG to CF, but not sue if it will work with BMDC files. I think this is for image sequences.
You could convert to Cineform RAW and use CF debayering.

Although John and I both already posted this in response to your first post... I can't figure out why you're trying to work directly with RAW for an edit...

It's the worst way to work with raw material IMO. The process is pretty simple...

Resolve: 1 Light > Proxy > NLE > XML/EDL > Resolve: Color (can be as simple as applying a secondary LUT to all clips, drag and drop) > XML/EDL > NLE > Master > Deliver

The only real concern (I guess this is opinion) would be how fast CinemaDNG is processed through Resolve and what kind of benefits a serious GPU (or GPUs) and CPUs are for decreasing transcode times.

The entire AE process is unnecessary.. .that's why they include Resolve with the camera.
 
I forsee raw almost unworkable for a lot of people- in practice.

which is better. 1, 2, or 3

1 Shoot directly in prores or DNXHD

or

2 SHOOT in RAW / then immediately transfer to favorite editing codec / then destroy raw files to release drive space.

3. Same as 2, but possible cineform as the new master.

any thoughts?

thanks

It'll all depend on what you're doing. I'm so used to shooting RED RAW that it's probably always gonna be 2, but it's good to have the option of 1+REC709 for really quick stuff.

thanks Kholi, yeah I figured 2 as the highest quality workflow, plus saving space.

, my basic needs would

a. general footage for features/ web.

b. GREEN screen { Ive never shot 4 4 4 green screen before, so I dont know if the improvement will justify shooting raw , transferring best takes to edit format { destroy raw footage}

I should add I dont know what codec to green screen in from 4 4 4 raw .


{ or just green screening with 4 -2-2 , as now }

c. Matching to 3d animation / vfx

No reason not to use CinemaDNG unless you just don't like the workflow.

Resolve > DPX = Real deal Keying

Could also use ProRes4444 out of Resolve. Either way, all things equal you'll pull a better key every time.

c. Matching to 3d animation / vfx

Again, CinemaDNG.

That's the thing, you could always work with the slightly lesser format, so it's your choice.

thanks, never used the workflow.

not sure what you mean by real deal keying. i guess you mean finally the real stuff!

I notice they like dpx key on the red forum.....


Could also use ProRes4444 out of Resolve. .

thanks Kholi, really looking forward to getting my hands on this puppy!

Kholi and John ...thanks - giving me a beginners primer - personally I don't see any reason to buy this camera unless your'e going for the 13 stops by shooting raw - and since john is using a 17 macpro...I think the macmini server edition might be the cheapest entry point for macs - thanks again and look forward to the faq
 
If you are so inclined - you can also just import DNG into Vegas and edit at 1/10 the speed of Red raw. No controls over the raw image like red footage at this point.

Ultrascope will need a macbook pro or air + short form editing can be done on a macbook pro = macbook pro for everything

... but there is plenty of time to wait for the new ivy bridge release.

I´m just trying out some workflows.
I stopped using proxies about 12 years ago, cause my NLE was ab able to handle compressed and uncompressed SD and (later) HD material in real time - so why waist extra time and disc space on proxies?
And now I´m trying to find out, if Premiere also plays with DNG in the same way.
Talked to some guys in the know, and they said, that CS6 will be able to deal with 2k 12bit in real time on a macho workstation.
So there is no reason for me to take a tour through several programs.
 
I'm working off a macbook pro 17" i7.

John, I read your thoughts on the Alexa and how close its ProRes output comes to its graded Raw output, any thoughts on how the BMCC's Raw and ProRes outputs compare? Are they equally similar?
 
best option is to transcode in cineform RAW ...3.5:1 for VFX and 5:1 for other ...bitrates would be similar as prores but you stay in RAW workflow ... and is not hardware intensive ....personally i wouldnt consider any other option for high quality work....
for other DNxHD...
 
I'll probably start off just using DNxHD (185x?) then moving to raw as my technique improves, and Thunderbolt appears on Wintel laptops.

My beef is with the mac-centric file format (Why not NTFS that everyone uses?). Yes I know there are work-arounds, but there shouldn't have to be.

Oh yes, and I would NEVER destroy my raw files, EVER.
 
If what John Brawley said was true, that Prores/DNxHD delivers similar dynamic range, I may just skip RAW except for certain demanding shots like green screen stuff. Getting 5 times the storage space over RAW is pretty attractive, and being able to edit directly is even more efficient than the hacked GH2 workflow I have now.
