So I"m working on my machinima with Marc, my machinima buddy. I gave it a title..a working title, but one I like...It's called "Till Death Do Us Part"
It's not a comedy...duh!
Anyway..all machinima needs sound effects and voices and background music.
Here are some resources. Some I found, some Marc found, and some were suggested by the people at Machinima Monday. BTW, If you're making movies in SecondLIfe, you should join this group and come to the meetings on Mondays, usually at 2pm SLT and 7pm SLT.
Wikipedia page about copyleft and out of copyright music - mostly classical music. On the Mac, you ALT left click on the file name to download it. Not sure what you PC folks do.
Freesound.org - database of Creative Commons licensed sounds/sound effects (not music). You enter keywords and get lists of sounds so tagged. You can see the other keywords used to help you find what you want. Then ALT left click to download
ccmixter.org - database of Creative Commons licensed music remixes.
Music Discovery Center - the search tool for ccmixter. I don't see keywords listed on selected songs like i did for freesound.org so it's a little tougher to find what ya want. Maybe just a matter of me playing with it some more.
Free Music Archive - you can sort by genre and then listen to selected tracks. Be sure to check the licenses but it seems that most are free to use for non-commercial projects
Actors' Sandbox - voice actors hang out here. They're running a workshop for voice actors. If you need people to speak in your movie, this might be a group/place to check out. I just found out about this at today's Machinima Monday. As I find out more, I'll update this.
