hi!Thankyou for using justanswer:
If someone has filmed you in the street, the video cannot be removed, although you don't want to be on it. It's the law in Spain, and why there are so many paparazzi in Spain, looking for famous people. The only way you can remove the video is asking to the uploader to remove the video.
If you have been filmed in a private space, for example in your house, you can report the person who upload the video. In that situation you will be able to remove the video legally, just say it to the uploader.
There a way to flag a video on youtube multiple times, so much times that it can be considerer inappropriate and removed. Visit the youtube's video url through diferent proxies, like, for example, http://www.vivalaproxy.com/ , http://zend2.com/. Don't logged in your youtube's account to do this, you don't have to. And flag the video. This methos is very use to alter the number of votes/view count of youtube videos too.
If the video was filmed by you, you can claim copyright infringement in this link
If that was helpful, don't forget to accept my answer!!
