Error Messages with ffmpeg Mentioned

Possible causes are as follows:

• Video file names or paths containing spaces, special characters (e.g., []{}*?$^@%+=&, etc.), or non-English text like Arabic may cause ffmpeg execution errors.

Please rename the video file to a new name composed of simple English letters and numbers, and move the video to a directory made up of simple characters such as English letters, numbers, and underscores. Ensure that all parent directories also follow this rule.

For example:

• C:/Program file/videos is not acceptable because it contains a space.

• D:/videos[001] is not acceptable because it contains special characters [].

• E:/中文 ceshi 개하였다 contains Chinese and Korean characters along with spaces and will cause errors.

• E:/myvideos001 is acceptable as it has no spaces or special characters.

• The original video may not contain an audio track. This is especially common for videos downloaded from YouTube, where video and audio are downloaded separately by default. If not merged, the video will have no sound. Please play the video to confirm.

• The video file might be corrupted and unplayable.

• The folder containing the video or the save folder may not have write permissions. Move it to a location with write access, or on Windows, right-click and select Run as administrator.
