BMCC DNG files Preserved ?

PostThu Mar 13, 2014 11:51 pm

Hello, I have an important quick question, as I have loads of footage shot on my BMCC, I have hard drives full of footage that I have to hand back to the producers in each project after I finished coloring the footage my self and exported and everything is done, what im trying to do before I send the hard drives is that I took many shots for Showreels/portfolio materials for the future, I managed to export proxies for each projects and cut what I want out of them out of resolve using an editor program such as Sony Vegas for example, and then i exported an XML back to resolve, they opened just fine but here at this stage im trying to export those shots with a format that not can still preserve the highest quality as shot only but to still have the features & options that DNG format can provide, such as exposure and white balance control, (the options found in camera RAW menu)

the question is this possible with a specific format or is it weirdly enough to say if i can export back to DNG?

tried DPX RGB 16 bit, quality and data information are preserved but not the camera raw features

Please advice

Yeah sure. Use a projector to screen the footage. Use the BMCC to record the projector screen image. Voila, back to capturing sensor data and recording it to DNG files.

generally what you would do is keep the DNG files as a backup and edit off of a transcoded or other codec codec (depending on what NLE you're using).

I've always felt a minimum of 2 backups is required for low-budget stuff, 1 of them goes with the Producer or DP and another goes to the Editor (So that in case the Producer accidentally spills coffee on the drives, the Editor still has a copy, and vice versa).

Generally if you are doing your workflow through DaVinci it shouldn't alter any of the DNG files themselves if you do it correctly.

I hope this answers your question.

I used uncompressed QuickTime RGB 10 bits out of Resolve, if memory serves me correctly. It uses acres loads of space.

I now use Cineform 444 film scan 2 16 bit. Much less space, great quality still.
