Hi Dianna,

Try to see if you can keep the video when you render a PNG sequence. You then assemble that sequence into a video in Premiere.

If that method works you can add the audio in Premiere by importing the half-successful video export you are getting now and removing the video track.

A detailed guide how to do things in premiere is posted here. Make sure you read the whole thread.

If this method does not work, you will have to composit in Premiere or AfterEffects adding your source video and your exported animation separately.
