Hi SuperM
Thanks for passing on the video.
What you can do is speed up the video clip so it seems quicker and more jerky.
Check out the wiki that explains how to do this( there is a video included as well)

I have also done a tips and tricks video that shows you how to do this:

In regards to downloading the clip, have you tried the new free realplayer that allows you download videos from YouTube? It is very good and you can convert them to mp4 so you can use them in trakaxpc.

I hope this helps and if you have any questions, please do not hesitate to ask me.
Best regards
