As I said, I already had this idea, but my effects won’t apply.
I copy the effects and click on paste attributes on my clip, I check the box “Time mapping”, but it doesn’t change.
Actualy, the footage that I am talking about wasn’t recorded with a camera. It’s a map entirely created with After Effect and I am sure that it’s in an interlaced scan (as I said, I can see both fields on Avid).
In fact, I think the problem comes from the project itself, but I don’t understand why the problem disapear when I switch computer and when I import the project in another one.
