GenMedia Producer Skill

Core Audio Production Workflow

1. Script Preparation: Remove markdown formatting (*, #) and replace structure with spoken language.
2. Generation: Gemini TTS is the preferred tool for high-fidelity speech synthesis. Use

   gemini_audio_tts

   for core synthesis. Fallback to

   chirp_tts

   for specialized voices. For long text, split into manageable chunks.
3. Assembly: Use

   ffmpeg_concatenate_media_files

   to assemble mixed-source audio.
4. Bumpers: Create 5-second intro/outro music using

   lyria_generate_music

   (with the

   lyria-3-clip-preview

   model), and ensure a smooth transition with

   afade

   .

Veo Video Generation (Veo 3.1)

• Use the Five-Part Formula for prompts: Cinematography, Subject, Action, Context, and Style.
• Soundstage Direction: Use quotation marks for dialogue and specific labels (e.g.,

  [loud thunder]

  ) for sound effects.
• Advanced Modalities: Use

  veo_first_last_to_video

  for transitions,

  veo_ingredients_to_video

  for character/style consistency across scenes, and

  veo-3.1-lite-generate-001

  for faster, 720p/1080p generation.
• If a request times out, retry once. If it fails again, reduce the

  duration

  parameter and inform the user.
• For voiceovers, ensure the video total runtime matches the audio duration (use

  ffmpeg_get_media_info

  ).
• The

  bucket

  parameter must be a full GCS URI (

  gs://...

  ).
