The error is caused by the file path containing spaces and potentially other special characters (A Girl Wakes Up in a Restaurant and Meets 6 Handsome Boys, but one of them...), which causes ffmpeg to fail to locate the output directory.
Solution:
- Rename your input video file to a short name using only English letters, numbers, hyphens, or underscores (e.g.,
video.mp4). - Move the video to a shallow folder (e.g., directly under
E:/) – avoid long paths. - Retry the processing. The software will then create a clean output path.
If the issue persists, check if the _video_out folder was created automatically; if not, create it manually at E:/_video_out.
