We produce videos as often as we have time and equipment to do so. We're planning on doing another video on camera car mounts next weekend. We have a backlog of topics, but Dominique is in film school and working full time at the shop, so there's only so much I can get him on camera. That, and when the equipment goes out on rental we're left empty handed. It can be really difficult to borrow demo equipment from vendors since we're not B&H or AbelCine.
I went to Shane's workshop last year since Video Gear was a local sponsor (it was great), but I guess I'm too cheap or lack the dedication to pay for his site. However, I do pay for a "friends of the ASC" account. It's completely worth it for the subscription to American Cinematographer. The breakfast talks are a bit of fun too. Holly, Delphine, and the crew do a really nice job putting on those events at the clubhouse.
Glad you enjoy the tutorials. We'll keep making them as long as resources permit.
