A low level exception occured in Lumetri Color (AEVideoFilter)

[Rosalyum]

Hello.

The error "A low level exception occured in Lumetri Color (AEVideoFilter)" keeps appearing in every projects, and it prevents me from exporting my videos (Error compiling movie). Looking at the error tab, there is a long list and the time stamp where the error occured. It's written "(AEVideoFilter:13)"

I'm using windows, Premiere pro 2018 (ver. 12.1.2).

The error doesn't appear when i use another laptop.

problem is that lumetri or colorista don't work correctly with luts (when you want modify exposure it is more brightness than real exposure) it is why i use lutcalc or 3dlutcreator to do my corrections so as you can see adobe have to work before fight against Davinci resolve....

If you're talking about the "Exposure" slider in the Basic tab ... that's a weird set of actions. Testing with a split image of a standard 20 part ramp and a box of sections at different levels I've made, on "increase" it's like combining a bit of Gamma correction-up (centered about 70% or so) with a Gain operation, in curves it's a very humped increase along with moving the White point up some ... and decreasing ... it's more like a standard Whites or Gain tool going down. Think taking the white point of a Curves panel, pulling down, all other data moving in a straight line black-to-white.

Basic tab's "Black" control is more like wagging a dog's tail ... based (pivot point) at about 20 on the left-hand 0-100 scale. Another very odd tool.

Color wheels give very standard Lift/Gamma/Gain response for Luma (tonality) sliders.

I've communicated both at NAB and MAX and via "electronic means" with Program head through engineers on the weirdness of the Basic "Exposure" and "Black" controls. If enough people do, we may get better tools there.

Other than that, the newer Lumetri with that nifty additional set of Curves ... and I've never been a big user of Curves ... is rather useful. Puzzling out a quick production workflow takes some testing and thinking, but then, learning to be quick in Resolve takes some testing and thinking also. So ... is it a big enough project to afford budget/time for the conform to Resolve? Or ... do you get by with Lumetri?

Here is how i organise my pipeline under Premiere Pro: i have my basic lut (kojicolor2383) that i underexpose by third with lutcalc. my base lut is at 2000iso: first underexpose at 1400, second 1000 and third 800 iso, like that i have all exposure i need. i use colorista IV to not meet aleatory bug crash like i said with lumetri next for more complicate coloriste need i use lutcalc or 3dlutcreator to generate a special lut from my basic one (kojicolor2383) and apply it with colorista IV. For the moment it is my pipeline and it is secure. i don't want resolve pipeline it is not my taste. here a tutorial with lutcalc: Working with V Log footage in 3D LUT Creator and Adobe Premiere - YouTube

Thanks for providing that info ... I always love to study the different ways people work! I'll have time to watch that a bit later today.

Reseting your preferences seems to help me when I get an error like this, but I normally get "a low level exception occurred in adobe scopes (Transmit::CreateInstance) " I made a video on how I solved my issue. A low-level exception occurred in adobe Premiere Pro - YouTube

I'm having the same issue while attempting to color the only clip on the timeline.  Updated my Nvidia 960M video drivers yesterday.

As a new user, this app seems very buggy. 😕

Hmmm ... graded 11 hour program across 51 clips of "slow video" last week.

Worked ok ... Pr can be a puzzler at times though.

What else is on that laptop for hardware?

Hi Neil,

It's an ASUS laptop with Intel i7-6500U @ 2.5Ghz, 16GB RAM.

Given that post by Adobe in one of the other threads about involving GPU acceleration and a fix coming soon in the next version, maybe I'll just put this Premiere thing on ice until all the bugs are worked out.

Resolve seems to work okay.

Had the same issue and believe me...I tried EVERYTHING for two days.

Lumetri kept crashing, not with all luts, but enough to disturb my workflow critically. 

The best workaround with some additional benefits is LUT MIXER, a simple Premiere Plug-In from Germany.

Works fantastic. Why can`t Adobe deliver something like that.

Couldn't find the answer in the forums but I managed to solve this error in my instance.

It seems that for me, Lumetri wanted to be the last plug-in in the effects control panel. I had swapped the hierarchy with neat video for noise reduction and it was causing issues. Once I placed Lumetri back at the bottom (last) of the plug-in hierarchy, it exported just fine. Hope this helps someone else.
