I purchased and downloaded the C1 Pro video and the quality is indeed below what I would expect from LL.
Just to be sure as a comparison, I started up one of the Lightroom 3 video's - as that is the only one I have on my laptop at the moment as I am traveling. And that video is miles ahead in sharpness and contrast. As old as it is, it is superior to the C1 Pro series.
IMHO the quality is lacking too much. I do inderstand your remark about finding a nice balance between file sizes for download and viewing quality. But I think this time the balance is a bit off. Esp related to the amount of work you all have put into this, but also related to the price we pay for this vid series.
I have watched a couple of the vid's of the C1 Pro series already and the content and the discussions are great though.
EDITED: It was not my intent to add anything to the discussion between you and Kaelaria. When I bought the video on 9 October and made myself comfortable for a first and entertaining look (which it was), it struck me how bad the image quality was. So I started looking for a setting to raise it (like going from 360p to at least 720p) but it is not there or I could not find it. It was then I started looking on the forum and read Erik's remark. Last night, watching the vid, I decided to leave a remark to give you some feedback.
My MacBook has a small 11 inch screen and I always look vid's full screen. I do hope the video quality will standup looking full screen on my 27 inch screen at home.
