We are working on one right now, but we've got the original MXF files from the camera.
What we did was to convert the RAW MXF files using using Sony's RAWViewer to 4k OpenEXR Half-Float linear files with the ACES gamut. We didn't use DaVinci or OCIO for the conversion because they both share the same F65 IDT which still beta and a bit off if compared to the results Sony's RAWViewer and Baselight are yielding. In Nuke we use the ACES settings from OCIO just to make use of it's sRGB RRT for monitoring. Do you have any info on where and how these files you've got were processed? cheers, Diogo On Thu, May 9, 2013 at 6:26 PM, Howard Jones <[email protected]>wrote: > The line in the manual > > Y = Power(10.0, ((t - 0.616596 - 0.03) / 0.432699)) - 0.037584 > > matches exactly the builtin sLog LUT, but I guess you knew that ? - I > couldn't see an sLog2 curve. > > Howard > > ------------------------------ > *From:* Lewis Saunders <[email protected]> > *To:* nuke-users <[email protected]> > *Sent:* Thursday, 9 May 2013, 21:52 > *Subject:* [Nuke-users] Re: sLog2 and S-Gamut from F65 camera > > Francois Lord wrote: > > Is there a way to convert from aces to normal sRGB for > > viewing, without using the RRT? > > You could do ACES to XYZ with the matrix on page 13: > https://github.com/ampas/aces-dev/blob/master/docs/ACES_1.0.1.pdf?raw=true > ...then XYZ to sRGB with a Colorspace node. > > If anyone has the actual SLog2 or S-Gamut docs (with the formulas > legible!)
