Bridie,
Another technique you can use if the video is not legible and you can't zoom in (not sure what software you used) but you can create slides in the video that give the steps. You can narrate, as I mentioned and of course, create a script, which is always good for
SEO when you post on your blog. Google can read the text but it can't read the video so I always recommend this.
Looking forward to viewing this again. Your idea is terrific and I'm going to use it!
Thanks,
Janine
