Let's say I want to overlay image slideshow or transition infographic over my video in Adobe Premiere. I know I can just add some slide or wipe tranistions to my assets, but those transitions look ugly, they don't have any easing or motionblur support. I also know I can animate those assets in AFX. But even with very good Premiere and AFX roundtrip support, this method still lacks crucial flexibility. For example, if I wanted to change asset display duration later, I have to either do it in AFX (and have hard time syncing it to audio for example), or go around with some freeze frame mojo basically spliting the animated asset in three parts (animation in, still frame, animation out).
I am looking for a way to handle those simple animations directly in premiere. Is there a trick or functionality I am not aware of? Or maybe some plugin? Basic functionality I am looking for is creating a slide tranistion with easing (nonlinear progress, speading up and slowing down) and maybe motionblur.
