The error message you are encountering indicates that the file path or name you are using for exporting the MOV file contains invalid characters, specifically the > character in 幽靈-Dance1>Dance2.mov. Windows does not allow certain characters in file names, such as >, <, :, ", /, \, |, ?, and *. To resolve this issue, try renaming the file to remove any invalid characters. For example, you could use 幽靈-Dance1-Dance2.mov instead. Additionally, ensure that the directory path is correct and accessible, and that no other processes are locking the file.
