What would happen if you compressed a clip to like 1/4th the original length and rendered it. Then stretched the resulting clip back to the regular length?

Pixelan step-time (Spice Filters plugin for Vegas) can do something similar, but it doesn't have a random look to it, so I wouldn't call it herky-jerky. it freezes a frame every x frames.

It seems to me too, that you could increase the speed of the clip and then slow it back down again. As long as you didn't resample any of the clips it should turn out jerky.

This is a very simple solution ... right-mouse-button click on the clip and choose Properties, then set the Undersample rate: to a lower value. This is a factor of how many frames of the clip to display. If you set it to 0.25 then only every 4th frame will be shown, for four times as long. It won't flicker like an old movie would, but it will give the stop motion effect. The lower the value used, the more extreme the effect will be.

Thanks for everybody's suggestions, but I think Chienworks (again) takes the cake. I'll try undersampling as soon as I get home. Sounds like it should work great.

Chienworks! You've done it again! - It must be in the manual or online help somewhere, but you've fielded a question I too wanted a quick answer.

Sooooo . . . when you say the lower the rate the longer the stop-motion effect, I suppose the higher the rate until I hit 25 [ PAL-land here ] it would in a sense "revert" to normal play. Is that correct?

Once again thank you. "Live Long and Prosper!"

Stop motion animation is traditionally filmed on "twos".....ie 2 identical frames are shot in a row on a 24fps camera giving 12fps , which is the smallest number of frames per second that will fool the brain/eye that the movement is smooth(persistence of vision) ...for example the best Flash web animations are at least 12fps or they start looking rather flickery.
The bottom line is that you use undersample for your clip to get the stop motion effect(as Chienworks already stated) and give it a value of 0.500 (if footage is shot at 24fps or in PAL which is near enough at 25fps). I haven't tried it with NTSC footage, but maybe you could convert the clip to 24fps and then undersample at 0.500.
Good Lark.

If you're going for an old film effect, might have some fun with the built in filmFX, mainly the flicker imo.

You can also do a bit in V/Dub, though an extra step for what works as suggested above - on a long project it might cut total render time.
