When I wanted to learn about (perhaps ironically) bookbinding, seeing videos about it was great. However, for quick reference back at how to (for example) tie a kettle stitch knot, a book is much quicker. Video is not as convenient for skimming or using in a random access manner, and search is definitely worse.

For learning something related to coding, I far prefer text to video, although that may be partly because it is easier to copy and paste into an editor so I can mess with it myself.
