Proper Color Correction Effect
Any chance of a proper colour correction / HSL effect so i can match input source in Res 7?

Re: Proper Color Correction Effect
Sorry to bump this old thread but it felt fitting instead of starting a new similar one.
So I happened to be doing playback for 3 commercial shoots back to back and the obvious choice was Arena since I've been using it for years. Content wise it's 1-8 driving plates on a LED volume (5600x2000px) as a background for car shots mixed with some static images to set a scene. Clip warping was a thing so I played them back, warped in Advanced output, brought back to a group to do color correction and sent that to the LED wall.
Everything was great until we started color grading. The filming crew, being used to color controls of Premiere/Davinci asked e.g. "let's dial down reds in the midtones" or "reduce the highlights" etc.
Resolume was struggling to provide that flexibility so I cobbled together a workaround of sending my precomp to OBS using Spout, color grading there and sending it back to Arena for displaying on the LED wall. Needless to say it was not stable enough for video playback. Eventually most color grading was done in an editing software, baked into an export and then dropped to Resolume, slowing down the process.
That sent me down a rabbit hole of coming up with a good solution for the use case. I considered going from Arena for warping to Davinci Studio for grading but it's limited in terms of live inputs. Sadly no Spout or NDI in. Buy a Decklink card, they said. It'll work, they said
I did try different native effects and FFGL plugins but no luck in getting a solid workflow. The Color Correction - Resolume Wire FX by Pixel Party was close but, as I found out, some update of Wire or Arena has changed how it works resulting in not being able to use it.
Has anyone encountered similar use cases and found something that works for them?
I'm kind of torn between trying to achieve it all in Resolume vs. finding another solution that could handle playback, warping of clips, live color grading and outputting to a screen.
Also, of course, +1 for native advanced color correction in Resolume

You can now use LUTs via the LUT effect.

Noted and I did try that. Loading a LUT worked but the video got some sort of banding and color breaking. Not sure if it was due to the LOG material I was working with or how the LUT effect manipulates a 10bit video (tried with Prores 422 HQ to be sure it wasn't a conversion issue to DXV).
That same banding/color issue was also visible in Adobe Media Encoder's preview, however, after baking the LUT into the video file, the issue was gone (and I did not have to apply the LUT in Arena).
Overall, a LUT might help but dialing in levels and colors should happen live so preparing a LUT and not changing it is sadly not an option for this use case.
