I can upload videos in the Call for Participation (CfP) form. Why should I do that?

If you have spoken at a conference or event before and there is video footage of it, this will help us assess it. We can better understand, evaluate and classify your submission. Last but not least, it helps us to get an impression of whether you convey your topics well. Don't worry, these videos will not be made public, but you should have the rights to use them.
