Matte key (with Alpha) how to make into a mov to change speed
I am struggling with an effect.
I have some animated shapes that I am using as backgrounds for an effect sequence to cut between two scenes. They came as two clips with alpha’s so I can layer them.
They are great but I would like to speed one of them up in order to use them for a multi layered wipe effect.
I can’t speed them up as they are a Matte Key effect and I am told the only way to change the speed is to re import them as QT’s.
I have re imported them ignoring the alpha and they come out green.
I have re imported them with ‘do not inverrt alpha’ andf they come out green. I have basically imported them in every way possible but no luck.I have also tried opening them in QT Player 7 as a sequence, again no luck.
I am using MC8.3 on a mac pro, 3.5 ghz 6-core. OS 10.10.5
Any help would be much appreciated.
