It depends on what you're learning. Try to learn to chop veggies and a video is superior to text. Try to learn all the inputs to a function, return values and thrown errors and a video is far inferior to text. The crossover point probably varies from person to person, and my guess is snobbery about videos is based around the personal differences in how a person learns and where what they already know or what they learn is on that spectrum.

There's also a wide (wider than text?) difference in video quality. How many videos out there are badly narrated sources available in text format?
