After talking to @Eric_Luth_WMSE (who had talked to @Jopparn):

• It's worth it to increase our hosting capacity (at least during the campaign) to be able to host the videos locally. This should resolve our issues with the videos not working natively in Wordpress.
• To do this we need to know which videos should be included on the page so that we can estimate the total size and make an order with The Generation.

So in short this is blocked by Wenderfalck for now in that they need to say which lightning talk videos to include and need to provide us with their produced videos.

Is there something left to do or can we close this task?
