The Poser walk designer seems to be designed only for people walking. How can I use it to design other sorts of movement repeated in a cycle, e.g. my scuba diver model swimming, or a slow-motion .AVI of a molecule vibrating?

only via key framing

Anthony- Once you do a walk cycle, and save it as a pose, it goes in (or can go in, I forget the exact procedure) the walk designer. Then you get a slider on it, I would guess you could then combine it with anything else that cycles, and is in there.

• I could easily animate my frogman model to go through one cycle of swimming, or a molecule to go through one cycle of slow-motion vibration. But how can I make that action repeat as many times as necesary for the whole duration of a Poser animation that I am currently working on, without me having to copy-and-paste each repeat in seperately? - Does anyone there know of a good AVI-editor that can chain and edit short .AVI's to make a longer movie?, as the Poser 4 manual recommends.

I just checked, it looks like you can't use the walk designer for this, as you can't turn off the built-in walk. But you can save all the animation, or a subset (I've never tried a subset, don't know if it actually works) as a pose, and then move the time slider to the end of the animation and add the pose's animation to what you already have- it's a lot faster than cutting and pasting.
