@gnarf37 I agree with @julienw , probably having a lot of canvas instead of videos it's better in terms of performance. Furthermore, this is a 'fake' video, because when tapping we are going to launch the 'open' activity, so we dont have to use `<video>`.  I've found an example here https://developer.mozilla.org/en-US/docs/HTML/Manipulating_video_using_canvas for manipulating frames.
