I am in the process of trying to create a 10 second animation of a horse and rider utilising posers sketch renderer; I have downloaded a free BVH of a horse galloping at 30 fps which runs @ 3 seconds. I have incorporated a rider and keyframed the movements of the rider within the 3 seconds. How do I now extend the animation to 10 seconds? Thanx in advance : )

In the animations pallet (Shift+Ctrl+V) add extra frames by typing into the total frame number box. Now hilight your existing animation by clicking on the top left square then Shift + click on the bottom right square. Ctrl + c to copy. Next position the cursor and hilight the next 90 frames and use Ctrl + v to paste.

I have worked very, very little with animation, but can't you just change the frame count in the "Animation Setup" box? You will see the duration of the animation change accordingly if you keep the same frame rate.

You were a couple of seconds before me, Phil, and with a more precise answer, thanks :-)
