Look on the red tinted first half, if they come and go there, then it isn’t the routine, but keep in mind, anything red will be way, way brighter than it should be in the faded footage, and some of te red and shadows were crushed in the very quick colour adjustment.

The deflicker can get false positives, this really is a rough pass (I spent about 30 minutes on it just now to make a sample) so it is quite probable that there are some processing artefacts.

Part of my process once I get going on these will be to post WIP scenes and have all of the eagle eyes on OT help find anything I miss, but these samples I barely looked at, they are just tests.
