Hi all,
I was thinking to sell some video courses, anyone have any experience on how to start? which platform to go for?

Need to consider how to prevent people download the video and share to other people....

There are many platform that let you do so but the most popular one is Udemy.

Thanks for the info

Youtube.

Or own paid style website.

There's many platform out there, alternatively if you have small budget you might also able to build your own web to sell video courses.

There was once a time where people recruiting member to upload their video for an amount of one-off payment fee. Like ViralTube back then. You can try google.

If you teach how to make money (such as stock trading), people actually sell their videos on their own site with merchant account at a very high price.

Yeah this is one of the platforms.

Use youtube but make it to premium content meaning that they have to subscribe and pay to watch your channel.
