Great video, bad audio

[John Rofrano]

[james williams] ” I shot some great greensceen video but the audio has that shot in a tunnel sound. Are there there any workable methods to help this situation.”

There is no fix for having the mic too far away. You really need to get a microphone close to the subject. You can try and EQ it or raise the volume but the sound of the room (i.e., tunnel sound) will still be there.

I would replace the audio. Get a microphone and have the people talking re-say their lines as they watch the video and listen to their recorded audio. Record them right into Vegas onto another audio track as they do this. This is know as ADR (Automated Dialog Replacement) and is done all the time in movies.

I agree with John about ADR with what’s already shoot.

For the future, I hope you’re not depending on your on-camera mic as your all-in-one go-to.

When the mic didn’t pick it up or there was too much other stuff it picked up (like room reverberation that can give you a tunnel sound) you will never get it as goods as if it was direct mic’ed with a good mic to begin with.

It doesn’t even have to be that good, just choose one with the right pick up pattern and get it as close to the sound source with out being in the shot.

Thanks for the responses guys. I actually did set a directional mic just off frame. The actor had to be somewhat animated. I was in a room that was thin meaning wood frame not solid. It was totally silent. I picked up no extra noises just the tunnel. I used a H2 zoom digital mike that had done well on some previous controlled projects. It gave me suprisingly full sound. Not this time. I have a rode mic but I always seem to get background noise with it. I’ll.take mic suggestions for this type of thing if you have any. I know the audio guys would lead me to mic setups. My video work is almost entirely generated inside the computer with little dependency on recorded voice. That’s kinda why I’m leading through you video guys and especially Vegas people since it handles audio so I see Sherri is trying to fight back although I think it is futile. How are you? Is your foot better?

Yea, a shotgun mic on a boom just outside the camera frame would be better and lavaliere mic on the talent would be best.

So if you had a pretty quiet room and the pick up was focused you may be able to salvage the audio. Have you tried inverting the phase. There’s a button on each audio track to reverse phase. Even if it doesn’t seem to do anything, start there, then add your processing (EQ, Compression, ect)

The “tunnel” discription can come from many things, so maybe a more detail discription of what your hearing or even posting a sample my get you specific suggestions. You can still see the major audio influence in Vegas and people use it for its audio capabilities but as far as restoration you may look at Adobe Audition.

I havn’t worked with a Zoom but depending on the Rode mic you have I know you can select it to be hypercardioid which will help you focus the mic, but an on-camera mic (meaning it sits at the camera position) my not be the best placement. Even if you have a quiet set and do all the right things to mic your subject, ADR sometimes is unavoidable.
