Alignment is not like baking cookies, where you can watch a short A-B-C video and then easily perform the whole procedure. If it were that simple, we'd all be experts already.

If you want to teach alignment, I'd recommend writing a series of lessons as web pages. Very few parts of that discussion require moving pictures (or even benefit slightly from them). Take setup, for instance. A learner gains little by watching a shaky movie of someone clipping an oscilloscope probe somewhere under a dark chassis. In print, you can show them that part of the schematic with the test point clearly marked, followed by a clear close-up photo of the probe clipped onto pin 3 of tube V21 or whatever. They already know that you hold the probe in your hand and move it toward the chassis before fastening it, so a movie showing that act is an annoying waste of their time.

In a spot where it's important to show something dynamic, you can embed a short video clip in the web page. For instance, I can imagine a short video of a scope screen showing how waveform A changes shape as you turn adjuster B.

Just my $0.02.
