I export a video from final cut pro and put it into compressor using the H.246 (or whatever that setting is) and I'm making it go into my external hardrive. Once it's finished, the video comes out alright, but there is no audio. I have done this before and it worked fine, but now it doesn't give the audio. It also just overwrites the current exported video, it doesn't do a new one with a new name even though I told it to.
This is an HD video btw.
