Re: [Nuke-users] Re: Luminance / Chroma B44 Compressed EXRs in Nuke
Thanks for the reply Seth. I just compressed some test images to OpenEXR B44 4:2:0 using rvio (which is fantastic btw), and when trying to read these images into Nuke, I get the same error as with images compressed using ProEXR from After Effects CS5.5. I have tried reading 4:2:0 yryby EXR in both Nuke 6.3v6 and 6.2v6, and it gives the same not compatible with the frame buffer's subsampling factors error. It seems like Nuke does not handle chroma subsampled EXR files properly? Is this a bug? Has anyone else experienced this problem?

[Nuke-users] photoshop differences
Hello everyone. It has been a while now that I'm trying to sort out a difference I have while using psd files in nuke. When I read a multy-layer psd file and view it directly, (equivalent to flattened in photoshop) it seems to be smoothing out or merging flayers in a different way than if I shuffle out layers and merge them back again. The strange thing is that, if I shuffle-separate each layer and merge them back again I get the exact same result as in photoshop (which is great!)... BUT, it differs from the psd file used directly from the read node. This means that the operation it does internally to flatten the psd file has some filter o some difference... since it even differs from the flatted photoshop result. Any hint on why is this happening? Any insight as to what operation is done internally while managing a psd file in nuke? Cheers...

Try a shuffle node after the Read and grab just rgba. I'm not at my machine, but from memory even the flattened result that you're after needs to be shuffled out to rgba. Not sure what the image is that comes directly out of a Read psd is doing. -Dan On Mar 2, 2012, at 5:40 AM, lozo nuke-users-re...@thefoundry.co.uk wrote: Hello everyone.

RE: Re: [Nuke-users] Re: Luminance / Chroma B44 Compressed EXRs in Nuke
Hi There are sample Luma/Chroma images on the exr repository on the exr project website; shows exactly what happens. http://www.openexr.com/downloads.html Generaly speaking: Nuke doesn't support Luma/Chroma encoded exr files. But problem is more complicated... Exr libraries provide 2 ways to import/export exr files: can say simplified and complex. Nuke uses complex way (IlmInputFile Class) because this gives ability to support multilayered files. But IlmInputFile Class doesn't support Luma/Chroma encoding (as far as I know). Simple way (IlmRgbaInputFile Class) support Luma/Chroma encoding but not support multilayer. So... the exrReader and Writer should be modified just to support this little useful feature. In my opinion chroma subsampled exr files are completely out of the exr workflow advantages. Currently when you render your composition to exr sequence you know that you have full quality base. From this base you can export whatever format you want: quicktime, mxf, avi, DPX seq or DCP. But what is advantage of Chroma subsampled exr files?? When you render it out and than you find that everything is ok.. you need to render it again in full quality. It waste of time. If you need proxy render you could use jpg sequence. But that is only my personal opinion ;-) Best Adrian W dniu 2012-03-02 17:23:14 użytkownik Deke Kincaid dekekinc...@gmail.com napisał: You should send a sample file if you could to supp...@thefoundry.co.uk.

RE: [Nuke-users] Re: photoshop differences
Hi Just one thing to clarify: Nuke psd reader doesn't merge layers from psd file in any way! While you save layered psd file in Photoshop you have option Maximize compatibility. When you turn it on, Photoshop merges all active layers and saves as uncompressed picture into the psd file. And this is exactly what you can see in Nuke as base RGBA layer. But remember, that Photoshop uses complex color management, based on icc profiles. So it's very likely that picture looks different in Nuke.
