#7884 expected str, bytes or os.PathLike object, not NoneTypeTraceback (most recent call last):

The error occurs because your input file is an audio-only file (.MP3) but the alignment engine (_rate.py) is trying to run its video-extension/slow-down routine, which requires a video stream. With no video file present, an internal video path variable is None, causing ntpath.basename() to fail with expected str, bytes or os.PathLike object, not NoneType.

This is a known conflict: the align / _video_extend step assumes a video track exists, but for pure audio input there is none.

Solution (choose one):

1. Use the "Speech-to-Text" (语音转录) panel instead of "Translation V/A" for audio-only files.

   • The left-side panel Speech-to-Text is designed for audio-only inputs and does not run the video-alignment/video-extend routine.

2. If you want dubbing output for the audio, use the "Text-to-Speech" (文字配音) panel.

   • First transcribe the MP3 via Speech-to-Text to get an SRT, then feed that SRT into Text-to-Speech to produce dubbed audio.

3. If you must use the video translation flow, convert the audio to a video container first (add a blank/static video track), then translate it:

   • e.g. in a terminal with ffmpeg: create a black video of the same duration and merge with the MP3, then load the resulting MP4 into "Translation V/A".

Also note your input path contains spaces (For Cap Cut current work, and a double space). Rename files/folders to simple English letters/numbers with no spaces or special characters, and move to a shallow directory (e.g. D:/Roshd-5.MP3) to avoid other ffmpeg path failures.

If the problem persists after switching to the audio-only panels, please provide the latest log file from the logs/ folder (copy the last ~30 lines) for further analysis.
