The error Unable to process >4GB files indicates that the audio file generated during the dubbing process is too large (exceeds 4GB) for the underlying library (pydub) to handle. This is a known limitation.

The root cause is likely that your source SRT subtitle file contains a very large amount of text, and the resulting synthesized audio (MP3) file has become excessively long and large.

Here are the solutions, in order of recommendation:

  1. Split the SRT File: The most effective solution is to split your large SRT file into smaller parts (e.g., split by time or number of lines). Process each part separately in pyVideoTrans, and then merge the resulting audio/video files using the "Toolbox -> Merge Audio/Video/Subtitles" function.

  2. Adjust Output Format (Temporary Workaround): The pydub library has issues with very large WAV files. You can try forcing the intermediate audio format to be something other than WAV.

    • Go to the pyVideoTrans installation directory.
    • Open the file videotrans/util/help_ffmpeg.py.
    • Find the function remove_silence_from_end (around line 1002 in your error log).
    • Locate the line audio = AudioSegment.from_file(audio_file).
    • Before this line, add code to convert the large audio file to a segmented or different format using ffmpeg command. However, this requires modifying the source code and is more complex.
  3. Check for "Audio Auto-Rate": In your TaskCfg, voice_autorate=True is set. If the配音加速 process creates an extremely long silent tail due to a bug, it might inflate the file size. As a test, you can try processing again with "Audio Auto-Rate" unchecked in the main interface.

Given the complexity of solutions 2 and 3, splitting the source SRT file (Solution 1) is the most straightforward and reliable approach.
