Thanks for posting in adobe forums,
Did you try to relink / replace footage from the bin for one of the clips with verticles stripes ?
if not please try that.
Thanks for that. Yes relinking and replacing only updated the clips with the wrong portion of footage making my promos look random and senseless. This is the first thing I tried before coming here.
I can only assume its a bug in CC as this problem first presented itself last week on day 1 of using PPCC, I've never ever had this issue over the years in earlier versions. Shame, making a 1 minute edit will become an hour process.
If anyone cracks this please let me know.
Turns out, my version of PPCC is reverting all interpeted footage back to its original form. So all my slow motion is not showing up because the original length of footage s a lot shorter.
One for Adobe to look into.
I've seen this when you open the project on a different computer, but never when opening on the same machine.
Either way, I believe it's a bug.
