2014 | R3D - CINEFORM workflow...

[Deon van Zyl]

Hi,

I'm busy working with a company that uses cineform .avi for all of their video.
They batch process BMCC, 5D MLV, BMPCC ProRes, Kinefinity all to cineform .avi

I've run some tests on the first batch process that we did (using the R2CF script) with my RED EPIC-X footage and all appears to have gone rather swimmingly.
I rated at ISO800 and I would often switch to ISO250 to check highlights while I was shooting.
The Cineform raw files are obviously ignoring this exposure metadata.

My question is twofold:

Will I be losing a lot of quality by pushing the cineform footage to match my R3Ds at higher ISOs?
Does anyone else use cineform and if so, is there a better workflow? Straight out of REDCINE-X for example?

cheers

Defaults for Cineform should be 444 12bit or else 422 10bit, you'll have to check what format you're going to, the actual Cineform codec merely resides in an .avi or .mov wrapper, so you can convert back and forth without losing anything. Most programs have no issue reading Cineform files, but occasionally gamma shift issues occur with Final Cut or Adobe.

There's also a difference between CineformRAW and debayered Cineform.

For example, CineformRAW retains raw data (compressed version).

There are peculiarities - say, DaVinci does not recognize CineformRAW as such and instead debayers it on both import and export.

RAW 4 PRO however does produce bonafide CineformRAW from RAW sources like BMCC, BMPCC, etc.
