Your last few videos have had the project file set to 60 fps rather than the 50 fps you usually have. It's causing juddering from every fifth frame being repeated. It seems to be from when you were at an exhibition three months ago and were actually recording at 60 fps, but the last few videos have been shot 50 fps as usual and ended up in 60 fps containers. I just thought I should let you know as it seems to be an accident with the project rate still being set to 60 fps from that one time. I always enjoy your videos and I have my monitor set to 50Hz so content like this always plays nice and smooth.
