●○○○ — Not much; I'm just letting you know about it.
Steps causing the bug to occur:
This is a fun one!
Use timestamp from receive live video to trigger storing frames/images to video
Use smoothing timed by display refresh to trigger a finalize event based on nonzero condition (became false)
Nonprofit. (or thread-split and confused computer)
Have you found a workaround?:
Use same time-source for both smoothing and storing frames/images to video.
I can e-mail you the composition if needed. Probably a fringe case, and also probably a pita to code a prevention for (although maybe something like the loop error when you don't use a hold node could work?).
