"Rec709 or will this double lut my output since the display is rec709 and were not trying to simulate rec709 on an srgb monitor?"
This is a common misconception.. The Rec709 viewer transform in Nuke *does not* simulate Rec709 on an sRGB display. It applies a scene linear to Rec709 camera encoding curve, which is then assumes will be shown on a Rec709/BT1886 display. The slightly tricky thing with Nuke's monitor out functionality is it doesn't allow you to control your display transform, or your legal (64-940) vs full (0-1023) range. This means you either have to have your video monitor setup to accept full range, or accept that one display or the other is going to be incorrect.. You're also going to want to calibrate your GUI display to BT1886 (Hiero on the other hand handles this much better) On Tue, Feb 18, 2014 at 5:49 PM, Feli <[email protected]> wrote: > I'm starting on a project and the setup will use Nuke in conjunction with > an external rec709 broadcast monitor. > > I have never worked with this way in Nuke, so I wanted to see if anyone > could give me a hand with double checking my workflow. > > > Hardware: > > Flanders Scientific CM171 boradcast monitor that is being driven via the > Thunderbolt port on a Mac through a Ultrastudio Mini Monitor (SDI). > CM171 is set to rec709. > > http://www.flandersscientific.com/index/cm171.php > > > Here is the workflow: > > 1) Shot on Sony F3 in slog uncompressed 10bit RGB > > 2) Converted in Resolve with slog2rec709 3d lut.
