WriteFileIf with a runtime function expression like lumadifference . But there was some bugs in avs+ 3.x with this. It works in 2.6 classic. There was some discussion about this somewhere IIRC. Not sure what changed or what the exact syntax change was

Subtract(clip1,clip2)
WriteFileIf (last, "log.log", "LumaDifference(clip1, clip2)>0", "current_frame", """ ":" """, "AverageLuma")
Other approaches would be psnr . You can print out per frame PSNR in ffmpeg (should be infinity for identical frames), but that prints out every frame value. Maybe some spreadsheet or grep function to reduce to only different frames
