Some channels do both since people have different tastes/levels of free time. I think it's a good strategy, though I don't know how it plays out on the money side. For example, a YouTube channel about automotive fabrication and tuning ("Gingium" in this case) will release high-detail build videos in series, then when the project is over, add a "Building a [x, e.g. Supercharged Off-road Miata] in 10 Minutes" condensed video with all the key moments.
