Re: [DCP-o-matic] XYZ image sequence colour problems

Thanks for your replies Carsten and Manuel. Answers to your Qs below Carsten. On 14/06/2017 11:18, Carsten Kurz wrote: I did this yesterday. On screen, the green cast was less pronounced than on my computer monitor, but I think was still present. Certainly the images had a dull subdued look to them. I also made a DCP in DOM from a Rec709 Quicktime reference file and that looked much more punchy. The director came to the screen test and said the DCP made from the Rec709 was more what he'd aimed for in the grade. So, it looks like my monitoring at office is exaggerating the problems, but that it still persists in the cinema. posthouse, or has it been extracted from the DCP you created? You may supply one of the original TIFFs to us, so we can have a look. And if possible, the same, or close by, image from a ProRes/rec709 source. The TIFF is the incoming TIFF from the post house, which is supposedly XYZ colourspace. Here are the files: XYZ still: https://www.cinebox.co/clockxyz.tiff Rec709 still: https://www.cinebox.co/clockrec709.tiff (from Quicktime for comparison) Once converted to DCP, the centre of the clock appears off-white. I'm a bit at a loss how to trouble-shoot this now. I'd like to determine for sure that I'm not doing anything wrong and DCP-o-matic is doing the colour conversion (or, in this case, the lack of conversion!) correctly before I go back to the post house. Any idea of some other software I could try out making DCP from the XYZ sequence to compare to DCP-o-matic's output? Thanks again for all your help.
