Whether it works depends on how good the presentation is, and how many views and subscribers you get. IMO that's the measure of success.
Over the last two years, I made several series of videos I posted on Youtube. About 30 on golf, 8 on kitchen/food tips, 6 on elderly health issues and fixes.
The equipment was very basic, a 200 baht tripod bought on Lazada, and my elderly smartphone for video and voiceover recording. I used free online editing software to edit the videos, and GNU image manipulation for photo labelling.
I have 280 subscribers, which is a piddling amount in the YouTube environment.
My success with viewers was varied. I maxed out at about 35 viewers with the elderly health series, perhaps the topic is too confronting. OTOH, I got 32,000 viewers on a video I made of one professional golfer. YouTube won't start commercializing a video unless the channel is producing a much bigger list of subscribers and audience.
I started making the videos as a creative exercise to ward off boredom during the pandemic, and did not expect to make money. I taught myself how to do video compilation and editing. I suggest you start with the same expectation, and not spend too much on equipment.
You never know what is going to click with viewers on Youtube. There is one guy on Youtube called Mr. Beast, who has 50 million viewers.
His shtick is outlandish challenges, such as fighting The Rock for $100,000. Park your brain cells at the door when watching.
Good luck.
