Is there an inexpensive software that can be used to make video tutorials? I was thinking of making a video of a small project from start to finish of a luminance image and then followup with adding the RGB data in a separate video. If I have enough bandwidth on my website I could zip the images used for download so that the data used in the video is the same that is available for download. I don't think this is redundant from any videos I've seen. That's the idea anyway. Short and sweet, probably 10-15 minutes for the luminance and maybe half for adding the color.
