@Charles BennettThanks for taking time to upload!
I can see difference between these, they are less subtle than film VS video option of the cross-dissolve transition (which isn't showcased in your timeline)
@JohnDon't need to shoot I can just take photos online,
or go with black and white image
There is a clear difference indeed in this case, video is the one is the slower ramp (cause linear)
so maybe it is more related to what it is crossfading too, and if there no media, then film and video modes behaves the same
In real situation, I suppose this has to be tested case by case then.
Thanks for the investigation!
