Hi OliPec,
I’ve spoken with Alfie and he has reminded me that the image wont play in a windows environment as it was created with apple prores software.
However i have retested the video and it will work from within blender.
It does highlight another issue for us however as the questions under the lecture are meant to tag the lecture to make it easier for us to find the course if students havent mentioned the course.
I’ll look into that also.
TLDR The file should be fine once you add it an image node in blender it just wont work in a windows playing environment.
Edit :- Tags seem to work so might be a temporary glitch.
