Overview

This node performs media processing tasks specifically for transcribing or translating audio from media files. It accepts a media file URL and processes the audio to either transcribe it in the original language or translate it to English. The node supports detailed output customization such as including segments, SRT subtitles, plain text, and word-level timestamps. It can return results directly or upload them to cloud storage and provide URLs. This node is useful for automating transcription and translation workflows for audio and video content, enabling easy integration with media processing pipelines.

Use Case Examples

  1. Transcribing a podcast episode to generate text transcripts for accessibility and content repurposing.
  2. Translating a foreign language video interview into English subtitles for wider audience reach.
  3. Generating SRT subtitle files with timestamps for video content to improve viewer experience.

Output

JSON

  • transcription
    • text - The plain text transcription of the media audio.
    • srt - The transcription in SRT subtitle format.
    • segments - Detailed segment data with timestamps if requested.
    • word_timestamps - Timestamps for individual words if requested.
  • job
    • id - Identifier for the transcription/translation job.
    • status - Current status of the job processing.
    • result_url - URL to access the transcription/translation result if response type is cloud.

Dependencies

  • An API key credential for authenticating with the No Code Architects Toolkit API

Troubleshooting

  • Ensure the media URL is accessible and publicly reachable; inaccessible URLs will cause processing failures.
  • If the language code is incorrect or unsupported, transcription accuracy may degrade or fail.
  • Timeout errors may occur if the media file is large or the server response is slow; increase the timeout setting if needed.
  • SSL certificate validation errors can be bypassed by enabling the 'Ignore SSL Issues' option, but this reduces security.
  • Batching settings should be configured carefully to avoid overwhelming the API or hitting rate limits.
