Not really. Video just doesn't lend itself well to searchability (is that a word?). YouTube's "table of contents" feature helps, but only when the video's creator actually uses it. Even if they do provide a ToC, it still doesn't help much if you're trying to find a particular sentence, or brief mention of a particular detail. Perhaps we also need videos with an index, in addition to tables of contents.
Right, but as I see it, there are multiple kinds of videos. Some are made specifically to be a vehicle for ads. You know what I mean, those 10+ minute long videos on simple tricks, where a short clip would suffice. They also usually lack any markers or chapters which makes skipping through them infuriating. I understand the rage here, I hate those with a passion, too.
But some long videos are excellent, well-made and informative.
Perhaps when the OP needs the info right now he may be more stressed and less in control of himself?
