I had never worked with such API before so it took me roughly two days, the AWS documentation is abysmal, and I could've one that in just a few hours if only they cared about documenting their APIs better. My biggest mistake was going for a kind of presigned URL that was not giving me much control over the size of files sent (I don't find it anymore for some reason, looks like the documentation changed). Go with PresignedPost, it allows quite a lot of control and it's an amazing way to avoid load on your servers.

>are you also encoding videos for adaptive streaming?

Can't help you with that, I only worked with images, best of luck!
