Resolve frame rate mismatch causing green overlay on monitor
Hey All –
I’ve been given someone else’s Resolve project (always hard to cook in someone else’s kitchen), and I’m running into a problem that PROBABLY has a simple fix.
In Project Settings > Video Monitoring set to 1080p 23.976 (which matches timeline settings), I get a green cast/overlay on my monitor. Photo enclosed for reference.
When I tab out of Resolve (put Resolve in the background), the image clears up and looks correct – until I bring Resolve back to the front.
I recognize that as likely a sync playback issue, so I experiment a bit and discover that if I set Video Monitoring to 1080 60i, the image is fine, but the timeline plays back at 60fps (as if I sped up the timeline).
Any suggestions would be MUCH appreciated! Thanks in advance!
Resolve 17.2.1
iMac Pro
MacOS 11.3.1
3 GHz 10-Core Intel Xeon W
64 GB 2666 MHz DDR4
Radeon Pro Vega 64 16 GB
Signal chain:
iMac Pro > UltraStudio 4k via Thunderbolt > SmartScope Duo via SDI > Sony Monitor via SDI

If it’s SDI to your monitor, might it be a Dual Link issue?

Are you sure the original footage is 23.976 fps?
-
That’s a good question – tell me more. I’m not sure what kind of issue that would be.
-
I just double checked – and yes, Quicktime Player reports the footage as 23.98, and Resolve reports the footage as 23.976. So we’re good there.
Thanks! That would have been an easy thing to assume and miss.

You are quite possibly trying to run a 4:4:4 signal to a monitor that is not expecting it or doesn’t support it.
-
It would be handy if you can screen shot the setup page so we can see. I think you have the monitoring set to dual link. Try single. Also there may be other mismatches going on between the timeline setup and the Ultra Studio output.

Ah! That’s a very real possibility. The project file is from a larger post house in LA, and my monitor is an older model.
I’m heading to the office shortly and will report back.

Got it! I’ll check that out when I get in, and post a screenshot.
As I mentioned in another reply, the project came from a larger post house in LA, and my monitor is an older model – so single/dual link and/or 4:4:4 setting could very well be the culprit.
Will report back!

SOLVED! Project Settings had “Use 4:4:4 SDI” checked.
Today I learned…
Thanks for all the help!

I have a couple of presets that I’ve created to reset a lot of those settings when projects arrive from other facilities. Saves going through a lot of settings to find the problems. Also when setting up new projects it is really helpful, especially where caching & renders go and what codec, as well as all the Decklink settings
