I'm using Django and html5 to display videos on a webpage however with more videos, it will take forever to load with all (or a lot) on one page. So when a user uploads a video how can I automatically generate a thumbnail for the video, or better yet let the user decide the thumbnail (by scrolling through frames).
I've had a look at this question/answer but I can't see how when the thumbnail is generated it will add it to the video model, and where this functionality would go in the Django app (the form, view or another file all together).
