Exr B44

[Mark L. Pederson]

Graeme -

Hear some "buzz" in FX community about EXR - B44 format - (a new flavor of EXR file format) are you on case? REDCINE export to it? Folks over at Digital Domain are gonna want it -

The Assimilate team is testing it as well I believe -

[Jeff Kilgroe]

B44 spec was just released on December 15th... Only ILM has been testing/using it thus far (as far as I know). I know we'll see it trickle down into the bigger editing/compositing apps pretty soon. I bet Eyeon, Apple and others will have support in their apps by NAB. ...At least I would assume so. Makes sense for REDcine to support EXR export (actually, how could it not support it) and having the new B44 spec in there just seems like a natural progression that should find its way in by the time the camera ships.

I hope I'm not making too many ASSumptions.

Yes, EXR is supported. B44 not at the moment, but software is upgradeable :)

Graeme shot me an email and took me to school on B44 -

sounds like you end up with 4:2:0 -

[Graeme Nattress]

You don't end up, necessarily at 4:2:0, but that's the mode you've got to use if you expect real time playback, according to the notes.

Well Maybe B44 is not all it is really cracked up to be. And for FX work witch is what I thought it was desinged to do getting on 4:2:0 color space seems like a big problem.

[Graeme Nattress]

Given that it's mentioned that it can be played back in real time, I'm guessing it's a format you render to for playback for larger files, rather than the short number of uncompressed frames you could load into a flip book.

[Don Woods]

Yes true.. I'm not doughting it will be a good format. But not as realtime as i guess I thought it would be.

[Graeme Nattress]

Be interesting to hear from the developer what they intend the use of the B44 compression to be though.
