The action video cameras from the Go Pro company have been responsible for many creative videos in recent months. Here's one I saw just today and really liked the perspective/s. The video was edited by Kelsey Wynns and shot by, well... by Bishop - his Great Dane.
Kelsey recently purchased a pair of GoPro cameras and had one mounted on a collar around Bishop. Resulted in some cool shots - even dog owners who spend a lot of time at the local dog park probably have not seen these views! You can read more about the project on Kelsey's blog: http://kelseyw.com/
Kelsey confirms what I was thinking when I first saw the video - he used Twixtor for the motion manipulation effects, cool thing that Twixtor!
As I watched this, I was reminded of an assignment I used to give to my Video students some time ago, as we were learning about creative camera composition and POV shots. One of the examples I would give them is --- think of storyboarding part of the day from the point of view of your pet. Really, I did!
