There's over 200 videos on the Jack Corbett video channel.  Over the years the technology for doing internet video has improved vastly, so you can expect the most recent videos to be of much improved quality over the earlier ones On most of the newer videos you should be able to view them in full HD video on your television set. This is because I am using the new Nikon Z7ii mirrorless camera with the finest Nikon lenses, shooting at 45 megapixels.
