I realize you're probably looking for a wide, more extensive selection of clips but there are some really nice free HD clips to download here http://www.beachfrontbroll.com/

Tom and Sharke,
thanks for your replies.
This is what I am asking for.

I´m starting to make some vids for my songs,
using Sony Movie Studio Plat. 12. 
Til now its really fun
to work with this software. Anyhow the workflow "feels" 
really intuitiv and comparable to Splat- but in video editing.
 
Somebody here in the forum once recommends the Music Studio .
Don´t remember who, but it´s really easy.
