2 min vidéo édit - need to be free use Commercial&Personnal

Hi to all,

I have a short clip (2min duration), it's a simple jewelry engagement ring casting. I need to make this clip sad, like with some video stock of happiness couple, memory scénario.. and now with the destruction of the ring it's the end of relation.. see what i mean ?

This editing need to be free use. I juste need to put it to social network without any right.
No limit. Clip need to be at least 1min.

Clip in private. (550mo)
