How long before we have good automated information extraction from videos?

About five years ago, I felt sad that the best / most informative information on so many things had moved to video because video monetizes much better than text, but it now seems plausible that, in the next N years, automated systems will be able to take a 30 minute video and turn it into text that takes 5 minutes to read.

Edit: I tried the suggestions from people who've said we're there today and none of them worked.
