Hi Joan,
I know it has already been mentioned, but I just wanted to throw my 2 cents in about having audio in the next version. I find Kinovea incredibly useful for something quite different than it was designed for; I use it as an animation tool. It's super handy to be able to go frame by frame through the motions I have animated, mark up the arcs, poses, facial expressions and output that for reference. Having sound for both lip-syncing the characters and sound cues like crashing doors, splatting characters, and other nonsense would be absolutely awesome. Just thought I'd toss that in there, and say thanks for a really slick, user-friendly program!
Cheers!
Rob :-)
