I am editing an interview. There is one spot where the speaker laughs really loudly, so I tried to lower the volume of the laugh a bunch, and also put a track of ambient (empty room) noise underneath to mask the fact. When I tried this, the audio wigs out, like a rapid vibration. Almost like the two tracks are interfering with each other or something? Am I doing something wrong? Any ideas? Thank you!
Is the room tone from that same shot the laugh is?
Honestly, I wouldn't do audio work in Resolve just yet.
And actually, I think and editor or colorist shouldn't do it at all. There are qualified professionals using the right kind of tools and workflows just for that. And you get a nice fixed file to place under the video tracks ☺
That said, if you can duplicate that track structure in PP, Avid or FCP, you'd be one step closer to figuring out if its a problem in your workflow, your files or the tool you used.
I also recommend you ask an audio professional about it. Its amazing what audio pros can do inside NLEs using the simplest tools.
