How to create a video for a map?

well, he wrote that you'll figure it out from there!!!
but I couldn't!
I go to "new object," and then I don't understand what to do!!!
He shows me standard maps, but I can't create my own!!!
Besides, I can't figure out the author's scenes either!!!!
I know, I'm the most clueless student!!!! But so what?

[censored] how can you not create your own map? I'm at a loss...

As far as I remember, the sequence of actions is as follows: you create/open a map (in which the video will be), then you perform the actions from Serik's instructions, etc.

Of course, if for some reason you can't create/open your map, then I don't even know...
