For me, it really depends on the type of video. For fixing cars, I'm usually looking for something specific enough that there isn't a lot of chaff. It was probably recorded and edited on a phone just to splice the clips together. Probably the default thumbnail that youtube extracted from the video.

For product videos, if Project Farm did it, look there first. Otherwise, I look for someone has a lot of videos for competing products with basically the same format, not over 10 minutes.

Tech videos are the hardest, I often still prefer text. Maybe look for links to the docs in the description? I still get duds though.
