Too much room for error when reading R3d in directly, not to mention the
speed hit due to de-bayering and full resolution as mentioned before.
I totally agree that transcoding everything to dpx files is the way to
go. This will give you:
1. full control over how the transcode happens across the show (gamma
space, priamries etc)
2. much superior speed in Nuke due to having uncompressed rgb channels
to load and only having to deal with the resolution that is actually
required (especially if you shot on 8k and only need to deliver
regular DCP or hd resolutions)

Cool, thanks for the feedback guys. The speed hit seems like a no-fly...

R3D's are going to be slow because they need to be debayered.
You're also looking at more room for error by exposing all of the
debayer settings to the artist, and more room for instability by
getting third-party libraries involved.
I would stick with DPXs.

*Subject:* [Nuke-users] R3D "Live" source plates in Nuke
In the past we had experimented using quicktime files directly in
Nuke as source plates and it was pretty much a disaster,
unstable, inexplicitly slow at times, and checking around that was
a concession from a number of shops. Fine in theory, seemed OK,
but inevitably when you got to a real shot, trouble.
I'm just curious if anyone has had any experience with using R3D
files like this. We'd be working at 4K from a Red Dragon, I'm
thinking on the plus side the compression would make for faster
interaction, but potentially on the negative side some of the
snappy scanline efficiencies might be lost, and of course,
stability is key. I've also noticed that the firmware in the
camera can be a real issue in getting successful reads in Nuke, so
there's a thing...
We're going to do some testing, but just curious if anyone had any
war stories.
Thanks in advance!
J.C.
