I agree with many of the comments here related to the logistics, atmosphere, and skills necessary to properly record, produce, and host the media of woodworking classes:
- Good video work requires at least two 1080p DSLR or dedicated video cameras. Three are better, four best.
- Full-time camera operators make sure detail is shown and distraction minimized. Static cameras don't work except for B-roll kind of footage.
- Lighting is a more challenging than it looks. High quality lighting (lumens, color, no shadows, no-flicker) is expensive and must be coordinated.
- Sound is best captured by lavalieres or operated boom mics. One is needed for each speaker. General area microphones will pick up every distracting sound of the teacher, students, tools, and incidental background noise.
- Setting up a workshop room for video recording means half the benches or work areas have to be empty (or the camera sees the backs of people). A lot of work goes in to directing the video to avoid production getting in the way (shooting other cameras, video team communication, awkwardness for the teacher and students, replacing batteries, adjusting lights and mics, etc.).
- Files are huge! 90 minutes of good 1080p DSLR video is nearly 30 GB. For four cameras, that is 120,000 MB (bytes). With a 1 Mb (bits) upload speed, that's 11 days to push up to a host. Hopefully, a final video could be compacted to 6-10 GB with decent quality.
- One popular video could generate 500 views. That's 5 TB worth of bandwidth to pay for. (Clearly, YouTube and other hosts use massive resolution and quality/compression algorithms to reduce this, but how much quality should be traded off?)
- Editing can take a while if your standards are high. Figure 8 hours of editing per hour of video.
- Better figure some minimal background music, voice over, on-screen text, if you've already gone this far.
I think what usually happens is that someone with the space, tools, video equipment, and editing skills to do a professional job (for example,
Joshua Farnsworth's Wood and Shop) converts all that into a monetary stream (business) which either ends up on DVD or internet stream. The free stuff is usually done by a lone wolf in his own shop that he's set up with years of trial and error, and has the correspondingly personal idiosyncrasies that make us all watch YouTube videos with our fingers on the comma and left arrow keys.
(The YouTube shortcut keys to speed playback and jump ahead 5 seconds.)
That said, I have a DSLR, tripod, and a Zoom H6 with a few mics that I'd loan for a day to the cause of a local recording session if anybody else has the time to manage all the rest. Frankly, I think it would work a lot simpler for a teacher to teach to the camera and minimize the distractions and gear required (a la
Paul Sellers). This can be done with just a DSLR and smartphone. Simplicity (and expertise) is why Roy Underhill and Norm Abram's shows work so well and lasted through many seasons. Any good looking, well spoken, skilled woodworkers out here looking to start a career on the big screen?
