What I'm looking to do can be found on

I really want to be able to do this!!!
Can anyone describe a step-by-step process
for doing this or direct me to a website?

Here's the link to the actual movie file - if that's what you are interested in. Its a Quicktime movie and its save disabled so I cant dissect it easily.... I suspect it was made from an original video of the dancers set against an easily removeable background, the solarised and edged with either a photoshop tpe package, of a movie compositing package, and then compressed with the Sorenson QT codec in QT v3 or 4 for maximum compatibility....

Here's one of a wide variety of ways to do it.

Capture your video to your hard drive. Try to use a bright or light
colored background when shooting the video. as paulD says.

Use video editing software like premiere or vegas to turn the avi
file into a series of jpegs.

Import the jpegs you want into Photoshop.

Change them to grayscale.
Adjust the contrast high enough to bleach out the background as much as
convert back to rgb,
play with the colour balance (and anything else) until you're happy with the results, save each file as a numbered sequence
in a tiff or bmp format (if you use photoshop you could record all this as an 'action'),
then reimport the sequence into video editing app.
then export as wmv/asf

adaption of the above will work for a gif format, or flash or many others.

Would I be wrong in suggesting rotoscoping? It certainly looks like it's been rotoscoped (drawing over live-action images) but that's a lot of work!!

In Premiere you can export all the frames (100s) into one massive photoshop image (if youve got enough RAM/CPU power) then adjust the images all in one go - every frame gets exactly the same treatment all in one go. When youve got it right you just reimport it back into Premiere and the huge image becomes a movie again. Rotoscope drawing of images based on the movie is fine if you are Disney, but the software will do this much(!) more easily. The main thing to spend the money on is good lighting (backlighting etc) of the dancers.
That said this particular movie has had drawing tools used to add the edge-line around the bodies - the hem of the skirt for instance. The frame rate is quite low so there aren't too many frames to work on.
