How to create a video for a map?

The console doesn't make mistakes. You made a mistake; you wrote the wrong address...
Write this in the script:

StartDialogScene("/Maps/SingleMissions/MyM1/S1/DialogScene.xdb#xpointer(/DialogScene)")

Your video is located in your map, not in the root of the data.pak archive...

Initially, my video was located at that path, and the problem was the same, and I wrote the path correctly. Then, I used an archiver to create a DialogScene/MyM1 folder in the root of the map and moved everything related to the video there. I decided to create a folder structure similar to the developers', thinking it would help, but alas. So, I have both Maps and DialogScene in the root folder, which means the script should be written correctly. Also, I copied the path to the video from the string in the property tree of the editor and checked it 100 times... Everything seems to be correct, and the StartScene window in the property tree sees this cutscene and doesn't reset when it's selected, and it opens and plays normally in the editor, but in the game itself, neither through the script nor through StartScene, there is no reaction. I suspect that maybe my game version is corrupted because this doesn't make any sense, but everything else works perfectly, which is strange.
