ProEXR 64bit for CS4 - WIN/MAC

[johnvid]

Not sure if anyone here uses ProEXR but if not might be a good time to try. Here is a link to the beta version for DL

Hey john, check out this rig at www.videoguys.com/diy7 and tell me what you think.

proEXR is a very very cool format. Especially for vfx. It can contain multiple channels and meta data.

So for example your one EXR can contain:
R
G
B
A
Beaty Pass
Spec Pass
Reflection Pass
Radiance pass
etc etc :p

Also if your working in stereo you can put the left and right eye in one file.

Not sure what you mean by 64bit though. No image format goes that high. These are 32bit float.

I think by 64bit they mean the native code, ie works in 64 bit CS4, as opposed to the 32bit ersion installed on a 64bit machine, I think the VRAY image format is 96bit? It stores everything & more.

I tried to check out the page Caliboss but it wasnt there, do you have a better way for me to see the info?

[David Gray]

Could be not sure. There is really not much need to go above 32bit float though. It can represent values above 1 and below 0. So way more than you can usually see.

The next step would be 64 then 128 anyway wouldn't it? 96*3 or 4 doesn't get us to any "real" bit value. Unless it's just 32bit per channel with no alpha which would make it 32bit float like open EXR.

Can't find any info on it, sounds interesting though.

Pretty annoying that Adobe isn't supporting OpenEXR natively.

Yeah it EXR's should be handled natively by CS4, but its a crude implementation of it, there have been loads of people telling the dev team they got it wrong and adobe where unwilling to accept that, most people where using the old CS2 EXR plug in, in CS3, that may still be the same for CS4.

I think how they get to a figure like 96bit, is 32bit for your colour info, and then every other channel is another 8bit.
