Export your animation from Poser by selecting the whole animation and making each frame a different 3ds file. Once in vecta, open the first file : xxxx001.3ds and a window will pop up, asking you to import it at a sequence or a single file. Chosse sequence, pose your model ( only the first frame will be displayed ) in the 3d view. When you will export it to swf, vecta will render each frame after the other one and voila, you got your anim ( but huge size! ). You'll have to optimize it in flash...
