Quote - ... Any suggestions on how best to make animations of wireframes (don't need renders) from Poser? I tried a 400x300 movie using the preview renderer, 90 frames, and it's almost 7 MB. Without buying software - what's the quickest (preferably scriptable) way of making an animated gif that is small? (Really only need like 4 colors).

you can use mencoder (no istalation required) - not directly to gifanim but the file size of similar animation to yours (two props - one movable - and ground, with res 1080:560 and 100 frames took 800kB) - of course everything depends on the output quality you want.

You can use it inside python script (as I do) because it is a command line. Poser must render series of images and mencoder puts it together with any (almost) codec you want (and you have FULL acsess to all codec's command so you can get really good results).

In doc file they mentioned it could make anim gif directly but you need to download additional library which I just cannot find anywhere.
