Brian,
I was having trouble capturing analog video and audio simultaneously which I replied to in another thread. Anyway here is what I am doing. It involves getting an audio mixer program.
1) I capture my analog video through a digital interface with a USB
connection and record it in Power Director.
2) At the same time I capture my Analog Audio in an Audio Mixer
Program called N-Track.
This allows me to have as many audio tracks as I want. I can then E.Q,
add some compression, reverb or whatever effects I need to make
all the audio tracks sound awesome and then mix them all down into a
single .wav file.
N-Track has a "sync to video" function that matches the audio and
video from Power Director perfectly and puts the composite track in
Power Director's video track. I can then split the audio and video in
Power Director and edit my Video track there. The result is a great
video with awesome sound.
3) N-Track costs around $54.00 but it is a powerful program and user
friendly. You can download a free version to try but unless you buy it
you will get an obnoxious embedded sound in your mixed down tracks.
This is N-Tracks way of forcing you to buy the program. The latest
version is N-Track 5.0.
By the way, I also have a Behringer Eurorack UB1002 which is a
10 track external mixer that I have a microphone, camcorder audio
output, Cassette Deck, CD player, Guitar, Bass, keyboard/midi and
drum machine going into my N-Track. So I am pretty much set to add
whatever sound I want to my videos.
This is a pretty elaorate setup so I don't know if your needs are worth
the cost. The Eurorack mixers have given way to the Xenyx line but
they're still affordable. You can get the Xenyx UB502, 5-channel at
www.musiciansfriend.com for $44.99 or the 10 channel for $69.99. But
you may be able to find some good close-out deals for the Eurorack
series on the internet.
Anyway, good luck in accomplishing your goals.
