Despite its power, Scan has no graphical user interface (GUI). You must use Command Prompt (Windows) or Terminal (Linux/Mac via Wine). Here is the classic workflow:
scan_x64_v2.exe --detect-pitch samples/
"YTPMV Scan x64 v2" refers to a specific, high-density video project format featuring 64 simultaneous video samples, often based on logo editing or musical "scans."
