How do you guys go about inserting video lessons in your language routines?
For some languages they might actually be the most comprehensive learning source; most channels end up after a dozen or two of them.
I personally prefer reading whatever contains explanations about the target language in an L1; because reading is faster, I can move through the text more conveniently as well. If I have time I might try audio lessons, but from my experience I either focus on content or on form. As for audiovisual lessons, I think there is too much time that goes away for explanations themselves, for introductions, for effects, for repetitions. If the video lessons can be made a good use of by just listening, then I'd probably give them a try in parallel with some not so attention-driven activity; otherwise I'd skip them altogether.
On the other hand, new YT channels pop up all the time and for some languages they can't be neglected; I'm thinking about Syriac, Guarani and a few others from my research. Even for larger languages it might be the chance to have instruction on your own L1 when not English.
The fewer times I've actually incorporated YT or any other lessons on my desk study time, I've paired them up with a textbook proper, the way I do with audio-only courses like Linguaphone, and I'd prefer really short spans, no longer than 10 minutes. I confess I've mostly just listened to the audio instead of watching the video, though in the case of learning a new script I'd force myself to watch it.
