Keep em coming, please. PIA should be grateful for the exposure you give them.
The manufacturers are very, very grateful for the exposure. Some of them actually chase me down before the show. Although it's a ton of work (you can see the uploads are occurring at 4:00 a.m. with training sessions starting at 8:00 a.m.), they're a lot of fun, and folks have always seemed to appreciate the work.
I think the non-rigging seminars should all be filmed/posted too. However, there is a large diff between the 10 minute FI's (Field Interviews) and an hour/2 hour long presentation, and there is a great difference between the volunteer room monitor that manages 9 training rooms vs needing 9 cameras going at once, with a minimum of 3 operators, and then the editing/collation/storage costs of the roughly 100 two-hour sessions. PIA doesn't have a grundle of $$, as they're entirely volunteer-based. It sure would be nice to have the ability to catch them all. PD is filming/uploading their own presentations, they can be found on the PD website after a while.
