Share copyright video + my face which comment the video

Hi,

Reusing copyrighted content without the owner's permission may be allowed under certain circumstances. For example, if you just use small parts of content protected by copyright for commentary purposes in your own work, this may be considered as "fair use".

That's said, keep in mind that fair use doesn't apply automatically, even if you don't intend a copyright violation. There're also no guarantee that you'll be protected against a copyrighted claim.

You can learn more about YouTube and fair use here.

Hope this helps.
