Yup, I’ve been following your issues. I’m capable of rendering video, but not audio.
The only “help” I seem to get from Sony is to be told that my system can’t handle the audio render (not enough RAM and processing power) however, my specs are more than adequate, besides, I record and edit sound just fine. Putting it together is the problem.
Let’s hope there’s someone out there with a suggestion. Your sample vid looks like what’s happening to me.
