Moire in rising mist shoot
I did some timelapse shots of rising fog on a DSLR and it looks OK when I run the video in QuickTime but there is substantial moire when I preview it in DR 12 and then on TV. I didn’t change the frame rate on import. Are there any things I might want to play with? It isn’t a critical project but I’d like to see if I can reduce the effect. The moire is like subtle graduated bands of grey that follow the movement of the fog across the screen.

That’s banding not moire. Most common cause is using an 8 bit codec not a 10 bit. There’s a lot of ways to have introduced the problem.
How was the original timelapse made? What codec did you choose to render the timelapse in. What codec are you outputing from Resolve? What TV are you watching it on? Every step there is a potential to cause banding.

Wait: you’re using Resolve 12? That is a very, very old version of the program, back from 2015. Sounds to me like you’re describing typical 8-bit problems in reproducing fine details smoke or leaves or water. -
I’ve only just upgraded from a 2011 iMac to a 2015 MacBook Pro ☺ I will try version 15 soon to see if it works efficiently, but just in the middle of a project now. When you don’t have money you do what you can with what you have and I’m just glad this app is free as it allows me to do so much.

I’ll look into those codecs and get back. I had no idea where to start looking as I’m learning on the run.

Here are the settings I’m using. First capture is the original file, the others from DR. Its only the one clip that has the banding as its of rolling fog or mist. The banding is evident on import to DR but not in the original.

H264. Likely the 8 bit problem. Resolve settings are fine except you should be using 1080p not PsF.
Also weird that the pixel aspect is reporting 1440 x 810. Likely just quicktime players inability to get info correctly. I never trust QT player for anything much.
