Posts from Video clip on the map (adventure dialog).

It's better to do it like in the example, just use your own x, y, and z values, and then adjust them to your liking through trial and error. It's simply easier to direct it to the desired point.
Clarification: I do it this way because I don't know the principle behind each of the parameters listed above.

A user had a question related to this topic. For this reason, I will explain what I know (in more detail).
First, you need to create a new dialog in the MapPropretiesTree:

Then, expand the "dialog" tab, the newly appeared "sentences" tab, and add new lines.

Click the "New" button next to the "text" line, and a window will appear where you need to enter a name.

Did you create it in the map editor? Other videos won't launch.
