PERSONA: You can create a new persona, upload your own persona or re-use existing personas. 

Here, let’s create a new persona. 

• You’ll need to enter a character description to help the system generate a persona that fits your vision. This can include details like appearance, style, tone, age, and any specific traits you want the character to portray. 

Example: A young woman with dark braided hair, layered jewelry, and a black jacket with bold patches. She sits in a podcast studio setup with a black microphone in front of her, speaking casually but with playful confidence. She doesn’t look directly into the camera, instead angled slightly as if talking to an interviewer.

PRODUCT PLACEMENT (OPTIONAL) - This is a marketing strategy where you can feature brand’s product within content. 

ACTION:  is a specific type of instruction you give the AI to define what the character or scene should be doing in the video. It focuses on the movement, behavior, or interaction taking place — like gestures, expressions, or physical activity — and helps guide the video generation engine to produce realistic, dynamic motion.

Example: Mid-shot, steady framing with podcast equipment in view. She smirks while speaking, eyebrows raising at her punchline. Subtle hand gestures underline her words, and her delivery feels witty and conversational.

AUDIO TEXT: is the spoken script or dialogue you want your AI-generated character (persona) to say in the video.This prompt generates the voiceover or speech, which is automatically synced with the character’s lip movements and facial expressions using VEO3's advanced voice-to-animation system.

Example: Everyone’s like, ‘AI can’t feel music.’ And I’m like… neither can half the DJs I’ve met. But if the algorithm makes me dance—who cares if it has feelings?

BACKGROUND SOUND: lets you add ambient audio or sound effects to your AI-generated video — such as music, environmental sounds, or subtle effects — to make the scene feel more realistic and immersive. It enhances the atmosphere of the video and supports the story or action taking place.

Example: Muted studio ambience with a faint low-fi beat playing softly in the background, giving it podcast energy.
