Step 1: Create Your Story and Scene Prompts with ChatGPT

First we need a structured cinematic story that will be converted into scenes and images.

Use the following prompt in ChatGPT.

You are a Hollywood-style cinematic short film scriptwriter.Create an original dramatic short film story that will be visualized scene-by-scene in bulk.GOAL:
Perfect visual and narrative consistency across all scenes — same characters, same costumes, same cinematic world.FIRST OUTPUT: CINEMATIC BIBLEGenre: Drama, Thriller, or Sci-Fi (pick one and lock it)Visual style:
Cinematic realism, high contrast, film grain, widescreen ratioColor palette:
3–5 dominant colors, lockedWorld:
Time period, location, atmosphereCamera style:
Wide establishing shots, dramatic close-ups, depth-of-fieldCore theme:
One emotional theme (betrayal, survival, redemption)CHARACTER LOCK — 2 MAIN CHARACTERS ONLYCharacter 1 – Protagonist:
Name, Age, Background
Appearance: hair, eyes, skin tone
Costume: exact items and colors
Personality traits
Signature item
MotivationCharacter 2 – Antagonist or Ally:
Same fields as aboveRules:
No new characters after Scene 1
No costume changes
Signature item visible in every sceneThen generate 10–12 scene prompts.Scene structure:
Scene number
Title
Setting
Characters
Action
Emotion
Camera shot
Visual details
Optional dialogue
End beat

This step creates a Cinematic Bible + 10–12 scene prompts which will define your entire AI film.

Step 2: Convert Scenes into Detailed Image Prompts

Next we convert the scenes into image generation prompts for Google Whisk.

Use this prompt:

Convert each scene from the story above into detailed text-to-image prompts for Google Whisk.Each prompt must include:
- Character descriptions
- Exact costume details
- Setting
- Action
- Emotion
- Cinematic visual styleFormat:
One prompt per line
No line breaks inside prompts
Include scene number at the beginning
Realistic cinematic style

These prompts will be used to generate images for every scene.

Step 3: Create Character Reference Images

To maintain visual consistency, we create character reference images.

Use this prompt:

Create two separate text-to-image prompts for the main characters in this story.Include:
Exact appearance
Costume colors
Facial features
Signature items
Cinematic styleOne prompt for Character 1
One prompt for Character 2
Make them highly detailed and cinematic.

Upload these character images as reference subjects in Whisk.

This ensures the same characters appear in every scene.

Step 3 (Part 2): Create a Cinematic Style Reference

To maintain consistent visual style across scenes, generate a style reference.

Prompt:

Give me a cinematic style reference prompt for this story based on the Cinematic Bible.Include:
Lighting
Color grading
Film texture
Mood

Upload this image into the style reference section in Whisk.

This keeps lighting, color palette, and cinematic mood consistent.

Step 4: Generate Consistent Scenes with Auto Whisk

Now open Google Whisk and install the Auto Whisk extension.

Steps:

1. Open Google Whisk.
2. Paste the scene prompts generated from ChatGPT.
3. Enable Auto Whisk bulk generation.
4. Generate all scene images automatically.

Whisk ensures that:

• Characters remain consistent
• Costumes stay identical
• Cinematic style stays the same

This step generates all scene images in bulk automatically.

Step 5: Bulk Video Automation with Grok AI

Now we convert the images into cinematic video scenes.

Use Grok Automation with this prompt:

Take the scene descriptions from the Hollywood story and write short cinematic animation prompts for each scene.Each prompt should describe:
Camera movement
Character action
Atmospheric motionRules:
Under 15 words
Cinematic and dramatic
Not cartoonishFormat:
Scene 1 to Scene 12
One prompt per line
Match prompts to corresponding scene images

Upload all scene images into Grok Frame-to-Video automation.

Grok will automatically:

• Convert images into animated video scenes
• Maintain character consistency
• Apply cinematic camera motion

Step 6: Generate Cinematic Voiceover

Now generate narration for the video.

Use this prompt:

I will paste a cinematic short film story structured as 10–12 numbered scenes with a Cinematic Bible. 

TASK: Convert the story into a voiceover narration script. Each scene = approximately 5 seconds on screen — keep narration SHORT and powerful. OUTPUT REQUIREMENTS: 1. Same character names, same world rules from the Cinematic Bible 2. Each scene narration = one punchy cinematic sentence, MAX 10-14 words. Present tense. 3. Include a Tone note per scene (e.g., Tense, Haunting, Hopeful) four. Format exactly like this: NARRATION SCRIPT Scene 1 [0:00–0:05] — 'Narration line here.' Tone: [word] Scene 2 [0:05–0:10] — 'Narration line here.' - Tone: [word] five. Match the action and emotion of each scene. Make it feel like a film trailer voice-over. WAIT for me to paste the story. Then produce the narration script immediately."

This creates a professional cinematic narration script.

Step 7: Final Editing

Import everything into a video editor like CapCut.

Add:

• Generated video scenes
• Voiceover narration
• Background music

Arrange scenes in sequence and export your cinematic AI short film.
