see att lnk.  I can't comment on yer thinking there, as I haven't seen the animation.  it is possible to delete frames, but it's much easier in video editor IMVHO.  unfortunately in poser it may be necessary to select-n-drag.  I won't tell ya to keyframe every frame, as it tends to cause them to go berserk and rant, even tho they haven't seen yer animation either.  hence if there's a keyframe every 15 frames, save those poses, delete all but frame 1, then add back the correct number of frames and apply the poses at the new keyframe locations, and use linear interp. at first. otherwise they're gonna tell ya to drag frames around.  the advantage we've found to new workers is that they are able to delete their work and start over from ground zero if necessary.
