Thread:Quality of materials? (1)

What level of quality are we after here? For example, I put up a link to a video for relative motion that we recorded in class using the interactive board. The tone is quite casual and there are a few quirks, possibly some minor errors, and many aspects that were not covered. It is obviously not a professional production with a script!

Is this sort of resource okay? I think it is great and my students love it (although the audio is a little low) but I don't want to set the standard at this if it is not what we are looking for.
