Can someone give me a link to a video editing software  (without a watermark on the final video) plz ?

Here ya go, Movie Maker isn't advanced, but it certainly does a good job for POV's and similar videos.

Thx ! I was using movie maker previously but I bought a new computer and lost movie maker (now unavaible on google)

Personally, I use VSDC video editor. Free and no watermark on the final video. It's also more advanced than Movie Maker, so you might enjoy it.

I have not had any experience with a video editor, but with my invisible expertise at video editing, movie maker is good. If you want to go super expensive, take the best option, Sony Vegas.

I hope you find a good editor!

I will try VSDC video editor tomorrow ! New videos !!! Finally
