    How to remove white background from stock footage?




      I'm quite new to using After Effects etc. I've bought a stock video of a padlock closing, which I want to place over an image. Obviously I want to get ride of the white background. The video is located on iStock here http://www.istockphoto.com/gb/video/hd-lock-opening-and-closing-gm483989635-2466392?st=541 1556


      I want to get rid of the white so it will be transparent. I've tried several options such as keying and also roto tool but none of them work properly and leave either bits of white showing or cut off parts of the image. Or it just changes the contrast colour of the image and makes it go a strange colour/ lose transparency.


      If anyone could help me I would really appreciate it!
