  • trying some stop-motion short cuts

    So, I’m doing a stop motion project and everything is going fine using the orthodox method (moving the object frame by frame and snapping a pic). However, for part of the project; I have to be outside a store front on a busy street. An object is supposed to scuffle along the side walk and enter the front door. Now, I can’t take up the entire side walk for hours while I shoot this stop motion scene.

    So, I thought of maybe I’d attach some very strong fishing line to the said object and pull it along the side walk while filming the action. Then I’d just use AE’s wire removal filter to kill the strings. After eliminating the string, I would then just cut out every other frame or so until I got that stop action look.

    Now, I’ve never used AE’s Wire removal filter and don’t know how well it works. I will do some tests but am trying to get a grasp as to what this is going to entail in the mean time.

    Does anyone foresee any “Gotchyas” or problems with this approach?

    Any suggestions are welcome.

    Thanks.

    Yeeeeeaaahh, I really just don’t have a facility large enough to shoot something like this.

    So, the wire removal filter is not such a good idea?

    Your greenscreen setup doesn’t have to be very large, only big enough to provide a keyable color on all sides of your hero object.

    It’s stop motion, so you could animate the object in place in front of the green screen, then once you’ve keyed it, move it across your background plate in AfterEffects.

    Does that make sense?

    Yeah, makes sense. The only problem is that the object needs to come down the side walk, up a small incline, and then through a door. So, I’m not sure if I could match all those angles and depth changes properly.

    I’m just going to have to do some tests this weekend.

    I think I’ll be able to keep the lines fairly tight Dave. Maybe I’ll rig them to a pulley to insure that they stay at a fixed position.
