How to check if videos have visually distorted frames?

I use ffmpeg to convert and analyze videos, mostly avi to mkv. Sometimes the video I'm working on has one frame corrupted in a random place, it looks like this:

How to check if a frame is visually damaged in ffmpeg?

This is not file corruption (not byte corruption), I know that since this video artifact is present in the original file, it is just visual corruption.

This command line gives an error-free result: ffmpeg -i myinput.avi {params} out.mkv 2> error_log.txt

How do I find if a template looks like any of the frames in a video file? Could any of the signal articles be helpful?
