So i tried to import a video into the design portion of the editor manually and by dragging the video file into the beat map folder. But when i go to manually change the offset of the video (because i want it to start at a different time that the editor doesn't go to) it gives me the osu! may not be able to read this video file error. Is there another way to either change the video offset or am i using the wrong file format. For reference the video is a YouTube video i converted into an mp4.
