This end-to-end automation streamlines video production, enhancing efficiency and consistency..

What does this workflow do?

  • Download Video: The workflow initiates by downloading the target video using the HTTP Request node.
  • Extract Frames: A Python Code node utilizes OpenCV to extract frames from the downloaded video.
  • Batch Processing: Frames are batched using the Loop node to manage load and optimize processing for the multimodal language model.
  • Generate Script: The multimodal LLM analyzes each batch of frames to generate partial scripts, which are then aggregated into a complete script.
  • Synthesize Voiceover: The full script is sent to OpenAI’s Text-to-Speech API to generate the audio voiceover.
  • Upload Voiceover: The finalized voiceover clip is uploaded to Google Drive for easy access and distribution.
