In the video I hope he nailed all the boards to the gravel board other wise he might be in for a shock when it all starts sagging.
The traditional method over here is timber arris rails into slotted posts, the cladding boards sit on a gravel board to prevent sagging, if it's just the rails that support the boards then the fence will sag if using the usual fence post spacings. If a gravel board isn't fitted then the rails have to be braced to avoid sagging, it is always better to fit a gravel board.
Yes, cedar is expensive, that stuff in the video was fencing grade but I'm guessing you want clear stuff for the bee hives.
Clear timber is more expensive weather it be softwood or hardwood, most softwood is from second or third generation stands, in order to obtain long clear finished boards then the timber has obviously to be knot free, it can be ripped down from a quarter sawn board, even then there is a limit to how many clear quarter sawn boards you can cut from a sawlog, true quarter sawn boards are expensive to produce for various reasons.
So to obtain clear slash sawn boards the growing tree has to be managed when it comes to obtaining timber from second or third generation stands, in general this is done around mid rotation (it can vary) by carrying out high pruning operations within the stand, this is labour intensive but at the final harvest at maturity it will result in being able to obtain a percentage of clear boards from the sawlogs and as such attracts a premium.
If you want clear softwood boards from a timber merchant then you might be lucky by going through the pile or display and finding the odd one but if you need more then you will generally have to "raid" several merchants to build up a decent quantity, for larger quantities you will have to pay the premium unless you can source from second hand or a gone bust sale.
