Change format to add information such as slides, alternative url to the video, presentation, etc
,
I usually find it interesting to have the presentation before opening the video. Also, the slides/handouts can be useful once you've seen the video and do not want to bother watching it again when you know the particular piece of information you are looking for.

I researched the different links on google but I might have missed interesting pages.
