The videos are not online yet, despite what you might think.
As we've been recording a lot more videos than in past years, we also have a lot more work ensuring everything is done right and that everything is ready. As part of that, we're currently using video.fosdem.org to store a few low-quality renderings of some video snippets so we can review if they're content or garbage.
These are not the final videos yet! The final videos will be of much higher quality, but we're not quite ready to produce them; expect another announcement here when that is the case.
