As promissed some fullscreen shots
Big thank you again, understanding alpha better helped loads; looks like all is working ok now.
I exported my clips alpha 'straight'.
then manually, per clip, adjusted the clip setting to straight.
It seems to be premultiplied as default (maybe a nice option for the defaults preferences in an update?
In Preview alpha is still black , but the clip triggers fine now
btw when my clip is exported straight & left on the default setting premultiplied, I still see the part that I had masked out completly in Ae. Same goes for the greenscreen & random white bits that were never there before export or outside of resolume.....
Without it being an issue, still finding that kind of hard to understand..?
Thank a lot for all you comments & help guys!
