want transparent background for PIP narrator

[Guy Mark]

I used Adobe Animate (AN) to create a lip-synched dinosaur character who then narrates a video (PIP-LR) that I am making with Premiere Pro (PR).  The mp4 exported from AN has a black background.  I checked the “ignore stage color—generate alpha channel” box in the AN media export dialog and automatically used Adobe Media Encoder to make the mp4.   How do I make the dino narrator background be transparent in the final PR video?  I even tried Adobe Express to make the background transparent in every frame, but downloading that changed video does not make the background transparent in PR.  Thankyou.

A mp4 does not carry transparency. You need something like Quicktime Prores 4444 with alpha for export settings

thank you.  I'll try that.

exporting that file type from AN worked well.  thanks again.
