If "The file contains an unsupported file format." is displayed

This is displayed when you select a file in a format not supported by Studio. The following cases are mainly considered.

A file in an unsupported format was selected

Check the file extension and reselect a file in a format supported by Studio.
If you selected multiple files at once, please check whether any unsupported file formats are included among them.

A file other than an image or video was selected when swapping an image or video

When swapping images or videos in a generated manual draft, only image or video files can be selected.
If you select an Excel file or a text file, the message will be displayed even if there is no problem with the file.

If "The file extension does not match the actual format." is displayed

This is displayed when the extension in the file name differs from the actual format of the file.

For example, if the file name shows ".mp4" but the data is not actually in mp4 format, this message will be displayed.
Please re-save the file in a supported format using a standard OS video editing app or image editing app, and then try selecting it again.
