Hey Guys...Hank is right, this plug in works fantastic!
I can post the settings that I used for mixing The Matrix (foreground vol, background vol, and fading).
I am seriously tempted to go back and re-do all of my RiffTrax re-authors with it...if I had the time. But for sure I will be doing Halloween and Matrix with it and any future releases.
You have lots of control over how low you want the movie audio to fade when Mike or Kevin are talking and you can control how fast to fade it.
Then only thing I noticed is this:
I had my RiffTrax audio sync'd perfectly to my movie audio, but when I mixed it with the new plug in, the DA syncs lines were off by .5 seconds or so. So I had to adjust for that. But as long as you are aware of this and adjust for it, then you'll be set!!
Just be sure to read the Help file, that comes with it, carefully, to understand how it works.
I went ahead and purchased the full version. $16 US is well worth it and they accept PayPal. But the trial version works fully and it looks like you can use is quite a few times before it expires.
