Historically speaking there were:

Game videos from versions: 2.3 (sceneries), 2.0 (landscapes) and 1.7 (features), I'm not mentioning older stuff, yikes.
Editor videos: 4 chapters from 2.1 and 10 chapters from 1.7.

But yeah I have to mention that making theese is like about 1-2 days for a video, more if I do subtitles.
