I'm trying to import a HAP encoded wav file into my video bin

I'm confused. "HAP" is a video codec and "wav" is an audio file format. I was unware it was even possible to even create a hap.wav file, but even if you did, it wouldn't import into the video bin because .wav is an audio file format, so Isadora would try to import it as an audio file. It certainly may be possible to create a file like this, but I've never used one with Isadora and to the best of my knowledge we've never tested with this odd codec+file format combination, and therefore I'd say that hap.wav is an unsupported media format.
