I was just curious how they do this? Is it a video camera trick or is it a still camera trick?

Here is an example (sort of): http://www.youtube.com/watch?v=kvTvo3BdICc

Maybe this needs to be moved to the video section?

It's an image manipulation trick. Essentially you take a still photograph, separate the elements out into layers, and use (for example) the clone tool in Photoshop to fill in previously obscured parts of the photograph. Then you bring it into a motion graphics program like After Effects, arrange the elements in a 3D compositing space, and move your camera to achieve the desired parallax effect.

Oh hmmm interesting. Do you know any tutorial websites on this?

The clone tool will keep you pretty busy if you do it this way. Alternately, you can take multiple tri-pod shots of the same scene with and without certain elements, then layer, and proceed as above.

Well yes, obviously if you can capture all necessary elements yourself you're better off. However I was assuming that the OP would be working from single photographs, as I'd imagine the person who created the YouTube video did (considering they were sports photos).

Another technique is to separate the elements into layers (foreground/background) and enlarge the foreground element by 10-15%. When you move the foreground element slightly from left to right, it will give the effect of depth. Images with good bokeh will enhance the effect.

Oh nice I didn't know this. This will help a lot. Is there any other tricks out there similar to this effect?
