David,
The pay-as-you go videos deal with a step-by-step approach to making a particular item. Some are more involved than others but can vary from four or five weeks to 8 or ten for the more complex builds.
The latest free offering is a taster for the latest project that is available by subscription. It is a project that builds a version of the tool cupboard that is evident in all his videos. Looking at it, I guess that it will run into the new year.
Basically, you pay £10 per calendar month, 12 payments a year, and get 52 videos, ranging from 30 to 45 minutes on average. Plus the occasional freebie. It has been going for a few years now, so there are a lot of back-uncatalogued videos to watch. When you sign up, it entitles you to download and keep the current series, and you can view, but not download previous series.
Paul Sellers is famous for voicing his pet attitudes to the craft, which some find tedious, but it is quite harmless and the teaching content is good on the whole. He does strive to use the most basic tools, so that it's accessible to those on a tight budget.
The free You-tube stuff deals in the main with outlining basic techniques, such as blade sharpening, saw sharpening etc. There is a free series on making a basic bench from scratch which is worth a watch.
Other than that, you pays your money and takes your choice. In some respects he's the nearest thing we have these days to the old-time wood-work teachers in school who are an extinct breed nowadays, idiosyncrasies and all.
Good luck
