I usually learn best when there is a reason, an immediate benefit, for doing so. Find a project that interests you and start working on it. You'll see what you need to learn more about to get it done, and that provides the motivation and context for learning it.

If that's not enough or too hard, find someone who knows what you want to learn, and talk with them, work with them.

Sorry if that's vague, but provide some more details about what you want to learn and/or your goals, and more help can be provided.

But your intuitions are right - video is not ideal at all for learning. Most people stop watching after the first 4-6 minutes (http://blog.edx.org/optimal-video-length-student-engagement).
