Thank you Lotfi.
Larache that's great you have interests in such art. Nowadays you can build up a cheap video editing workstaion and go on.
I do some editing, but usually it's just basic works of cutting and joining fotages.
Here is samples of my recent works.

If you have questions Larache just ask, I'd be more than happy to answer and share what I know.
