I've posted about this a few years ago with no luck an an alternative, but i'll try again and hope for the best.
Every year i create an animation for a year-end event. It originally started as 1 big flash animation that linked together about 180 frames of individual animation. Some of the frames were as basic as a name or an image - others more advanced or even videos. The key functionality is that each frame is pre-programmed to either stop, keep looping or auto-advance to the next frame - where it will stop and wait for the click of a button which advanced from frame to frame. The reason for not doing this in Powerpoint is that with flash i have the ability to blend between videos, animations and slides that loop a video or animation continuously.
Flash does this well but unfortunately it's very time consuming to programme the slides individually. I have always wondered if there was a better software that could be used to link together a serious of about 50 individual video files created in AE with an engine that would advance from video to video in a powerpoint-type way. If i could find a piece of software like that i could rather create all the elements in AE which achieves a more efficient workflow.
Would appreciate any ideas? I wondered if ProPresenter may achieve this but i'm still in the process of testing it.
