I'm looking for a Lisp library (or something that I can FFI-bind to)
that I can use to programatically output video files, preferably with
sound.  I want to be able to write the video frame by frame, drawing
each frame with some kind of graphics library like CL-GD.  Does anyone
have any recommendations?

Thanks in advance!

If you can find bindings to Image/GraphicsMagick you can build video. 
There is enough in my Cello project to get you going and I think I heard 
of another set somewhere.

For playback, I had initial success going thru Tcl/Tk which has a 
QuickTime Plugin. Thus LTk should work as well with sufficient glue.

Meanwhile, seem like cl-sdl should handle that, but I have never played 
with that.

fwiw,kt

I'm not sure I'd call (load "ltk-quicktime") glue, but if that's how
you want to think of it ... ;-)

ltk-quicktime /is/ the glue is how I want to think about it. Nice to 
hear it got glued.
