Check that you have credits available in your provider account
Verify the selected model is available
For custom providers: Test the endpoint URL in a browser or with curl to verify it's accessible
For local models: Ensure the local server (Ollama, LM Studio) is running
Review the console (F12) for error messages
Check the timeout setting if requests are timing out
Rate limit errors on long videos: Long videos are processed in several requests (see Long Videos). If you hit rate limits, wait and retry (finished parts are kept) or use a plan with higher limits
Some reduction is normal: the default prompt removes filler words, repetition, and promotional content
If content is missing from the end of the video, check the console (F12) for warnings that a response was truncated
For custom providers: Make sure the server reports finish_reason: "length" for cut-off responses, and that the model's context window can hold a part of about 12,000 characters plus the prompt
A custom prompt that asks for a condensed or summarized version will shorten each part
Ensure you have write permissions in the target directory
Check that the video title doesn't contain invalid filename characters (these are automatically sanitized)
Verify the default directory path is correct if using that option
PDF generation: PDF format requires Electron API access (desktop app only). If PDF generation fails, try using Markdown format instead. PDF generation may also fail if the transcript is too large or if there are formatting issues.
Cover notes: When "Create cover note" is enabled, PDF and SRT files will be automatically nested in subfolders. You can customize the cover note location using template variables like {ChannelName} to organize files by channel.
