We observed many differences between Resolve 12.5 and 14. The version 12.5 is not used anymore, but we use it as comparison to test version 14. We would like to share with you some observations we think useful to improve workflows in Resolve. These observations concern mainly workflows for SDR - HDR remastering.
Prores HDR Rec.2020 St2084 : Resolve 12 vs Resolve 14
On Resolve 12 the renders in Prores 4444 XQ, with colorspace HDR Rec2020 St2084 checked, presented a color shift in comparison with renders in TIFF. Colors are slightly different, mainly in Red, TIFF is conform with our grading, Prores is not.
- We compared renders (grading, TIFF and Prores) in a timeline in Resolve without color management to be sure renders are not modified. Grading vs TIFF : no difference on vectorscope neither on screen. Grading vs Prores : difference on vectorscope and perceptible on screen.
- Analyze renders in Transkoder (Colorfront) : color volume rotates slightly between two renders. It seems to us that it shifts like if render of prores was encoded in wrong primaries. The shift looks like a shift between R2020 and P3 primaries.
On Resolve 14 the problem does not occur when we select "colorspace". Our observation on this topic is that different colorspaces like Rec2020 and Rec2100 are not well described for the encoding in Davinci and does not make coherence with recommendations.
