Alpha channel exporting: any way to add audio?

[NotBobNudd]

Here’s a little background information. I’m not very experienced with VideoStudio. A friend of mine has been trying to make a stinger transition with audio for OBS but has struggled with crashing issues with some free software available. I suggested VideoStudio may be the solution however I’ve run into an issue in trying to make a prod of concept transition before he commits to buying it himself.

So far I’ve been able to make a simple stinger transition on an overlay track and export the alpha channel as it needs to have a transparent background. The issue is adding audio. Is there a way to add audio to this exported file without losing the transparency, or is there some other alternative method we we could try? The alpha channel export only includes the overlay and not the audio.

Thanks in advance for any help!
