Out in the woods last weekend I took a video of the forest on my N95.
Whilst strolling around I then did an automatic "muvee" where the phone edits the video, adds some sound and makes it a little mini 3gp movie for sending.
I used a Cubism style and ended up making it a bit like predator vision :-)
Then I have just had the fun of trying to get a decent editor to deal with the original mp4. As Vista and windows and Nokia don't want to play nice with it.
The AVS video editor handled it well, though it claims to handle FLV's (from ustream) but I cant seem to get that working
