Camera RAW Video editing causing light flickering

Question

So, this may seem weird but I really enjoy using camera raw to color my videos and I've been doing it for years. However once I render things back down in After Effects I tend to get some strange lighting flickering issues on certain scenes. I'm not sure what the issue could be and I've tried troubleshooting several things:

-Rendering tifs, pngs, exr [not supported]
-Not being as heavy handed with my editing
-Trying different versions of camera raw, after effects
-Using different frame blending methods
-Rendering video with a LUT laid over first and then rending down my image sequence before placing into camera raw. [Thought V-Log could be causing an issue]

My pipeline process is to render my video out in an image sequence first, take the first frame and edit it or use a saved preset for the look I want, import image sequence with camera raw into After Effects, render out the footage in H.264 format.

If there's any advise it would be greatly appreciated. Thank you!

If this is about applying edits in bulk across image sequences (not already-rendered video clips), the flickering might be related to Camera Raw/Lightroom image settings that are content-aware, such as Highlights/Shadows and Clarity. These settings are optimized for individual stills and in that way they work great, but if applied to images intended to be played as a sequence, slight changes in content from farme to frame can cause Camera Raw/Lightroom to calculate a visibly different result across almost identical frames, and that can show up as contrast-related flickering.

The video below goes through each edit setting and shows you which ones are most likely to cause frame-to-frame flickering. Note that he also discovered that applying certain raw profiles can make image sequence flickering much more likely than other profiles (such as Adobe Color vs Camera Standard).

The video is about Lightroom Classic, but the editing options are exactly the same in Camera Raw and produce the same results.
