#5602 LLM Resegment: Set OpenAI Model/Key in Settings.

The error indicates that the LLM Re-segmentation feature (used for correcting and re-splitting subtitles after ASR) requires an AI model and API key, but you haven't configured them yet.

Solution:

1. Go to Menu → Tools → Advanced Options → General Settings.
2. Find LLM re-segmentation AI channel and select either OpenAI ChatGPT or DeepSeek.
3. Open the corresponding translation channel settings (Menu → Translation Settings → OpenAI / DeepSeek) and fill in your API Key and model name.
4. Save the settings and restart the task (do not check LLM resegment if you don't intend to use it, or keep it unchecked to avoid this error).
