I commented on the content already, but I would like to say that the video format makes it much more attractive to listen/watch. I usually don't listen to the [german] audio podcasts, because it seems to require some direct focus/time investment for me somehow, but with the video all that is much easier. Also the navigation/orientation in the video timeline is way simpler that in an audio timeline, plus allowing links to certain passages.
I guess it's just easier for the user because you put even more work into it in the first place, so a big thank you!
