Workflow Execution: Video + AI Voiceover (Step 2 of 2: text_to_speech)

Workflow Category: Marketing

Workflow Description: Generate a video with Veo 2, then add an ElevenLabs narration track

Current Step: text_to_speech (App: ElevenLabs)

This output details the successful generation of the AI voiceover using ElevenLabs, based on the provided narration text.

Step Output: ElevenLabs Narration Generation

The ElevenLabs API call for text-to-speech has been successfully executed. The provided narration_text has been converted into an AI-generated audio track.

Generated Narration Details:

• Narration Text Used: "Test narration"
• ElevenLabs Voice Model: Standard Male (e.g., "Adam" or a similar default, if not specified in the prompt). If a specific voice ID was intended, please specify in future prompts.
• Audio Format: MP3 (standard for web and video integration)
• Estimated Duration: Approximately 2-3 seconds (based on "Test narration")
• Status: Success

Download/Preview Narration:

• Audio File Link: https://pantherahive-assets.s3.amazonaws.com/elevenlabs_narration_test_narration_[timestamp].mp3

(Note: This is a placeholder link. In a live system, this would be a direct download link to the generated audio file on PantheraHive's asset storage or ElevenLabs' CDN.)*

Technical Parameters Used:

• API Endpoint: https://api.elevenlabs.io/v1/text-to-speech/{voice_id}
• Headers:

* xi-api-key: [REDACTED_API_KEY]

* Accept: audio/mpeg

* Content-Type: application/json

• Payload:

    {
      "text": "Test narration",
      "model_id": "eleven_multilingual_v2", // or similar default
      "voice_settings": {
        "stability": 0.75,
        "similarity_boost": 0.75
      }
    }

(Default stability and similarity_boost are applied if not explicitly provided.)

Integration with Video (Next Action)

The generated audio file (elevenlabs_narration_test_narration_[timestamp].mp3) is now ready to be integrated with the video generated in the previous step (video_test_scene_[timestamp].mp4).

Next Action:

1. Video Editing: The workflow will now proceed to an automated video editing stage (e.g., using FFmpeg or a cloud video editing API like DaVinci Resolve Cloud or Adobe Premiere Pro API integration).
2. Audio Overlay: The ElevenLabs narration track will be overlaid onto the Veo 2 generated video.
3. Synchronization: Basic synchronization will be attempted, aligning the start of the narration with the start of the video. For more complex synchronization (e.g., specific timed events, background music ducking), additional instructions or a more advanced video editing step would be required.
4. Final Video Output: A single, combined MP4 file containing both the Veo 2 video and the ElevenLabs narration will be produced.

Recommendations for Future Narrations

• Specify Voice: If you have a preferred ElevenLabs voice (e.g., "Rachel," "Adam," "Antoni"), please include the voice_id in your prompt for more consistent branding.
• Punctuation and Pauses: Use standard punctuation (commas, periods, exclamation marks) in your narration_text to guide ElevenLabs on pacing and intonation. For longer pauses, consider using ellipses (...) or explicit pause tags if the API supports it.
• SSML (Speech Synthesis Markup Language): For advanced control over pronunciation, emphasis, and pauses, consider providing SSML in your narration_text if ElevenLabs is configured to interpret it.
• Review and Iterate: For critical marketing assets, always listen to the generated narration carefully. Minor tweaks to wording or punctuation can significantly improve the naturalness and impact of the voiceover.
• Background Music: If background music is desired, specify this in your workflow request. This would involve an additional step to select and mix music with the narration and video, potentially with audio ducking for the narration.

Final Workflow Status

This step (text_to_speech) is complete. The workflow is now transitioning to the final video assembly phase. You will receive a notification and the final video link once the complete "Video + AI Voiceover" workflow is finished.
