Let me try to understand. This adjustment layer...is it trying to blur footage that's underneath it in Premiere? Adjustment layers won't work once they've been rendered to a video file. Now, if you're saying that the adjustment layer isn't blurring something that's inside AE, that's another question entirely.
Thanks very much for your reply Szalam. I am a video producer and editor - not really an after effects guy. I do what I can.
Yes it is trying to blur footage that's underneath it in Premiere.
If I have the footage in AE it blurs it fine.
I'm just not sure my best method of doing this. Maybe I should chose my clip in premiere and replace with after effects comp and go from there? But then I still need to import my lower third assets.
When you render a video out of After Effects, it becomes just that - a video. So, things like adjustment layers are null and void; there are no layers anymore once it's been rendered.
There are several ways to make lovely blurs in a lower third. You could replace just sections of those shots with an AE comp in which you create the lower third. You could do the blurring in Premiere (using a mask in Premiere or a track matte you create with AE). You could import your full project into AE to do the lower thirds over it (this seems like the least-ideal, but it could be done).
That's fantastic. Thank you Szalam. I appreciate your time. This has answered my question.
Glad to help.
