Does anyone know of a reference source for buying rotoscope video?

I mean simultaneous orthogonal views from two cams 90 degrees to each other (front view and left side view, for example).

Ideally, I would like to find video for:

running horse

running big cat

running man

running deer/hind/hart/caribou

female ballet dancer

female ceili (traditional Irish) dancer

female rave/trance/techno dancer

flying bird

swimming dolphin

Maybe you can find the muybridge animations somewhere around the net.

Good idea, thank you.  I'll start nosing about.

The link demos my new pair of motion sequences for Aiko and the Mil Horse.  :D

       I have been looking for video usable for motion capture, i.e., to help develop Poser animated poses using the video as a guide.  The ideal would be a pair of videos shot simultaneously from a front camera and a side camera, set against either a plain or a grid background, covering at least one full motion cycle (e.g., left step, right step, and on to the next left step).

     3d.sk offers motion videos;  some are useful for motion capture, some are not.
     The 3d.sk animal videos are generally not orthogonal, but are shot at a random perspective angle.  They are of moderate usefulness.
     The 3d.sk human videos vary in value.  They do have a plain backdrop and are shot orthogonally.  Most of the female motions are unrealistically executed, however.  A woman slowly moves a sword around in one video.  To be of value for motion capture, she must truly swing the sword like she means to do damage, so that the timing and body balance are realistic.  Likewise, the video of a woman "running" shows a woman jogging in place on the studio backdrop.  But the leg motion and torso lean would be very different if she were truly running.
The videos of men fighting with axe, shield, sword are of more value because they are actually swinging the weapons and absorbing blows;  the timing and motion are realistic.

    I bought two picture books -with accompanying CDs- of the old Muybridge motion capture work, one for animals and one for humans.  All the image series were shot orthogonally against a grid backdrop.  For cyclical motions (walk cycle, run cycle, wing flap cycle), one full motion cycle is usually provided, although occasionally only a half cycle is shown;  you will need to mirror-image the poses to get the other half of the cycle.
     In the Muybridge work, a running subject really is running, so the timing and limb position are realistic.  The CD contains  a "filmstrip" JPG, a ShockWave Flash animation, and a series of separate JPG frames for each motion sequence.
     The CD will try to auto-play and prompt you to install a player for the flash animations.  Feel free to kill this, then select the CD drive, right-click, and choose "explore";  in WinXP this will show the folders on the disc.  Just copy the image folder to your computer to use it for motion capture work.  To play a flash, you can select the flash, right-click, highlight "open with..." and choose FireFox or other web browser.
     To do the motion capture in Poser, I suggest compiling the separate JPGs into an AVI in a video editor and then apply the AVI on a billboard in Poser.  If you have two AVIs shot from front and from the side, use two walls/billboards in Poser. Phil Cook offers a Rotoscoper Python script to help with this.

I looked up PhilC rotoscope python in freestuff and the marketplace. Found nothing.
