You might be able to use a combination of Trapcode 3d Stroke and the “growing vines” technique explained in this tutorial.

Have you considered doing your keying in After Effects? A possible workflow might be to capture your HDV content in Avid, transcode the footage to DNxHD and export as a Quicktime Same as Source. Import your footage into AE (it will be 1920x1080i upper field first square pixels). Key your footage using keylight and then export out of AE to a codec that supports an alpha…or just continue doing the rest of your compositing.

That’s a gray enough area that it is probably not worth the risk. By remixing you are creating a derivative work from someone else’s copyrighted material. It may be remixed or altered enough that one might not be able to tell…but there is a chance that someone could charge you with copyright infringement.
That being said, there are artists that are providing music and elements to the public for the express purpose of being remixed into a new work legally. That might be something you might look into.
Check out the Creative Commons website https://creativecommons.org/ for some info. You can also search for music there that you can legally remix and use commercially.Erik

The best thing is to use music that you have rights to use, either direct written permission from the artists (say if it is a friend or family member), or pay $$ for the appropriate master/sync license from ASCAP or BMI (or international equilvant).
If you intend to go anywhere with your film even submitting to film festivals they will require documentation proving that you have rights to the music contained in the film.
If this is just background music to paint a scene, it could be anything from just recording someone talking as though they were a DJ, find a friend who knows how to play guitar or piano and record them pounding out some notes. Look around for local musicians that might allow you to use their music. You have lots of legal options.Erik

Sounds like you have the “status” mode in Keylight turned on…
I’ve also seen Keylight do some strange things when using masks and presets.
Keylight also has a zillion different tweaks that can be used, such as bias that can help if the green in your background isn’t really all the green. Keylight comes with a PDF the size of “War and Peace” that does a good job of explaining how to use various settings to compensate for some common keying problems.
Another good trick is to follow the “super tight junk matte” tutorial to eliminate as much of your unneeded background as possible.Erik

You’ll find it a lot easier to add music in post for continuity and to avoid stepping on dialog. On every set I’ve ever been on radios, CD players, walkies, etc… are always turned off or so low you can’t hear it at all, or play nothing but silence. Nothing like smashing the illusion of your film’s reality if the song keeps skipping and changing between angles and cuts.

HD is upper field first. You can tell AE to render your HD comp using upper field see if that takes care of it.
HD 1920×1080 uses square pixels. HDV is 1440×1080 using 1.33 pixel aspect…which stretches out to 1920×1080 square pixel.Erik

I’d recommend asking this in the Trapcode forum. Peter Norby, the creator of the Trapcode plugs hangs out there a lot…

You might also investigate using WMV’s instead of AVI’s.
AVI itself is just a container, it can hold video encoded in any number of different codecs (divx, video for windows, Huffy, etc…). What codec you use can have a dramatic difference on the size and quality of your video. It can also be a headache if whoever you send the video to doesn’t have the same codec to play (decode) the video.Erik
