#6188 The srt subtitles were not read. The file may be empty or the format does not conform to the SRT specification:srtfile='

The root cause is that the target subtitle file C:/Users/zheng/Downloads/_video_out/eco-mp4/zh-cn.srt exists but is empty when the final assembly stage tries to read it. This usually means the translation step either failed silently or wrote an empty result, so there is no valid subtitle content to embed/attach.

To solve it:

1. Check the intermediate subtitle files in the output folder C:/Users/zheng/Downloads/_video_out/eco-mp4/:

   • en.srt (source subtitle) should be non-empty. If it is empty/missing, the ASR stage produced no subtitles — check if the video actually contains clear speech and that the source language is correct.
   • zh-cn.srt (target subtitle) should also be non-empty. If it is empty while en.srt is not, the translation step failed.

2. Delete the translation cache to prevent a cached empty result from being reused:

   • Go to D:/迅雷下载/win-pyvideotrans-v4.08/tmp/translate_cache/ and delete all files in that folder.
3. Re-run the task again without enabling 清理已生成 if you want to inspect the generated files first, or with it enabled after clearing the cache. If the problem persists, switch the translation channel from Google Translate to Microsoft Translate (free, no proxy needed) and test again.
4. If en.srt itself is empty, try using a different ASR model (e.g. large-v3 instead of large-v3-turbo) or enable 降噪 / 分离人声背景声 to improve recognition.

If the issue continues after these steps, please provide the latest log file from D:/迅雷下载/win-pyvideotrans-v4.08/logs/ (copy the bottom ~30 lines) for further analysis.
