VidNavigatorInstall

Overview

This node integrates with the VidNavigator API to perform various video-related operations, including fetching video transcripts, analyzing videos, searching videos, transcribing non-YouTube videos, answering follow-up questions about videos, and running custom or predefined tools from VidNavigator.

Specifically, the Get Video Transcript operation retrieves the transcript text of a given video URL. This is useful for extracting spoken content from videos for accessibility, content analysis, indexing, or generating subtitles.

Practical examples:

• Automatically generate transcripts for YouTube videos to improve SEO or create searchable archives.
• Extract dialogue or narration from educational videos for study materials.
• Use transcripts as input for further natural language processing tasks like summarization or sentiment analysis.

Properties

Output

The node outputs a JSON object containing the response from the VidNavigator API for the transcript request. The structure typically includes:

• result: The main data field containing the transcript information.
• Other metadata fields depending on the API response.

Example output JSON structure:

{
  "jsonrpc": "2.0",
  "id": 123456789,
  "result": {
    "transcript": "Full transcript text here...",
    "segments": [
      {
        "start": 0.0,
        "end": 5.0,
        "text": "First segment of transcript"
      },
      ...
    ]
  }
}

If the node supports binary data output (not indicated in this operation), it would typically represent media files or attachments related to the transcript.

Dependencies

• Requires an API key credential for VidNavigator API access.
• The node makes authenticated HTTP POST requests to the VidNavigator base URL configured in credentials.
• No additional external dependencies are required beyond the VidNavigator service.

Troubleshooting

• Invalid or missing API credentials: Ensure that the API key credential is correctly set up and has access to the VidNavigator API.
• Malformed video URL: The video URL must be valid and accessible by the VidNavigator service. Check for typos or unsupported video platforms.
• API errors or timeouts: Network issues or API rate limits may cause failures. Verify network connectivity and API usage quotas.
• Unexpected response format: If the API changes its response schema, the node might not parse the transcript correctly. Check for updates to the node or API documentation.

Common error messages:

• "Unsupported operation": Occurs if an invalid operation is selected; ensure "Get Video Transcript" is chosen.
• Authentication errors: Indicate problems with the API key or permissions.
• JSON parsing errors: May happen if the API returns malformed JSON or unexpected data.
