I've got a canon powershot. It has an inbuilt mic. I usually take interview-type videos, mostly indoors. The audio quality is poor as far as the purpose is concerned. I use pitvi as my editing software.
The question I have is...how easy is it going to be to record audio from another device and merge that with the video using pitvi?
I also would want to know about audio recording devices which support a lapel or a collar microphone.
