How can you create a video? which method do you prefer?

I don't have that much experience in making videos, but I prefer screen recording. This is because I feel it is more efficient, as you do not need to do as much work as making a slideshow. Also, the screen recording is easier to follow (because of visuals) and can be edited after.

As for easier ways, you could combine videos together, or use online services that provide animated objects (only applicable sometimes) or other services.
