Lumetri Colors causing colors to shift, curve points are uneditable, high contrast & low-level "exception" causes mass havoc
I made some color corrections to a project in Premiere CC 2018. Closed project and then needed to make edits to the same timeline. Re-opened project in CC 2019 (about a week later). Massive color shift I can't correct, Curve points are un-editable, and it kept giving me "Low-level Exception" warning on Lumetri.
Now any new project opened in Premiere will not work with Lumetri pre-sets and causes any image it's applied to have extreme contrast and extremely flat colors.
@Francis - thank you for the response; I'm sorry for my late response to yours! :)
1) No slider values changed, nor were there any LUTs added. Simply a Lumetri plug in that is native to PPro. Never installed any LUTs ever to my computer. The odd thing is that I had completed the project a week prior in CC2018. The following week, I upgraded to 2019 and was then asked to modify the existing project. Simply opening the project in 2019 caused this shift.
2) I've experienced the issue with both the RGB Curves(Stand alone effect) and Lumetri RGB Curves (haven't had as much an issue with Hue vs. Saturation). Initially, the effect acts as normal. But once you release the mouse and the curve point is set, it will not allow you to go back and adjust that curve point. I've had to either delete and reapply (stand-alone effect) or reset (Lumetri RGB curves) in order to adjust and change them.
3) I would get the low-level exception simply by trying to apply the Lumetri effect to a clip of video. Video is 1920x1080 Apple Pro Res 422, 29.97 Linear PCM, imported from a Ninja Blade drive and originally recorded via a Canon C100. It seemed to be an issue across all footage, but not necessarily all Lumetri pre-set choices. Ex: Lumetri>Speedlocks>Canon C300> SL Neutral Start would give me the exception, but Lumetri>Speedlocks>Canon C300> Clean Punch LDL would not.
Does that make sense? Happy to help fix this!
This sounds like a huge headache, and I'm very sorry for the trouble you are experiencing. It sounds like there are 3 individual problems, lets tackle them 1 by 1.
1) Color correction is hugely different from 2018 to 2019
I assume that the actual slider values have not changed - correct? Are you using any LUTs? Have you ever installed custom LUTs by opening up the application package/program files and installing them alongside the default LUTs that ship with PPro? If yes, this is what is causing your problem and I can work with you to resolve it.
2) Curves points are un-editable
In order to diagnose this one, I will need to know exactly which curves you are talking about. Lumetri RGB curve? Hue vs Sat donut? RGB curves standalone effect? The new curves in 13.0? Please describe the precise behavior you are experiencing.
3) Low-level exception
This is the most elusive of the bunch. A low-level exception simply means something went wrong, but we don't know what. If you are able to provide precisely repeatable steps that lead to a low-level exception warning then we can begin to try to diagnose what is going wrong. Think about this from the point of view of starting a brand new fresh project - exactly what do you need to do to get the warning - does it happen with all media, specific media?
Hopefully, we can help to resolve these issues.
Agreed! In this case, the project was complete and the client came back a week or so later (I'd literally upgraded the day before) and asked for a simple revision that included a new tag. I couldn't get anything to correct, so since the project was time sensitive, I imported the completed version back in, and used that to edit from, but I've seen this happen to some of my other projects trying to use the presets.

Always advisable to avoid updating projects midway through them. Is it possible to complete your CC2018 projects in that application, then move forward with new projects in CC2019? That's how I would approach it.
