Start Frame Prompts

Product Hero Shot

Ultra-premium product photography of [PRODUCT NAME] placed on a matte black 
surface, minimalistic studio photoshoot. Deep black background (#050505) with 
subtle gradient falloff, soft rim lighting outlining edges, controlled 
reflections on smooth textures. Cinematic lighting, high contrast, luxury tech 
aesthetic, sharp focus, shallow depth of field. No clutter, no text, no logos 
emphasized. Shot with professional DSLR, 85mm lens, f/1.8, ultra-high 
resolution, photorealistic, Apple-level product shoot, dramatic mood, modern 
and elegant.

Variables: Replace [PRODUCT NAME] with your product Output: Starting position, fully assembled, hero angle

End Frame Prompts

Exploded Technical View

Exploded technical diagram view of [PRODUCT NAME], every component precisely 
separated and floating in perfect alignment, suspended in mid-air against deep 
black studio background (#050505). Visible internal structure including 
[INTERNAL COMPONENTS], all parts evenly spaced showing assembly order. 
Hyper-realistic product visualization, ultra-sharp focus, studio rim lighting 
identical to hero shot, soft highlights tracing each component, controlled 
reflections on matte and metal surfaces. Cinematic lighting, high contrast, 
luxury engineering aesthetic, no labels, no annotations, no text. 
Photorealistic, ultra-high resolution, Apple-style industrial design render, 
dramatic and clean.

Variables:

• [PRODUCT NAME]: Your product
• [INTERNAL COMPONENTS]: Specific parts to show

Video Interpolation Prompts

For Runway/Pika

Smoothly transition from fully assembled [PRODUCT] to exploded view. 
Components separate slowly and precisely, maintaining perfect alignment. 
Camera stays locked, product rotates slightly clockwise. Cinematic motion, 
professional product animation, 4-5 seconds duration, 30fps.

Settings:

• Duration: 4-5 seconds
• FPS: 30 (yields 120-150 frames)
• Camera: Static or slow orbit
• Motion: Smooth, controlled separation

Frame Extraction

Using ffmpeg

# Extract as WebP (best for web)
ffmpeg -i animation.mp4 -vf fps=30 frame_%04d.webp

# Extract as PNG (higher quality, larger)
ffmpeg -i animation.mp4 -vf fps=30 frame_%04d.png

# Extract with quality control
ffmpeg -i animation.mp4 -vf fps=30 -quality 90 frame_%04d.webp

Using ezgif.com

1. Upload MP4 video
2. Choose "Video to GIF" → "Split to frames"
3. Select WebP format
4. Download all frames as ZIP
5. Rename: frame_0001.webp, frame_0002.webp, etc.

Background Color Matching

CRITICAL: Page background MUST match image background exactly

Recommended Dark Backgrounds

Color Code	Usage
#050505	Pure black with slight lift (recommended)
#0a0a0a	Slightly lighter, less harsh
#000000	True black (only if images are true black)
#1a1a1a	Dark gray (for lighter renders)

Pro tip: Use eyedropper tool on first frame background, use exact hex in CSS

---

Alternative Animation Styles

Rotation (360° spin)

Start: Front view End: Front view (after 360° rotation) Prompt: "Rotate product 360 degrees on turntable, maintain lighting"

Zoom In (Feature reveal)

Start: Full product view End: Close-up of key feature Prompt: "Smooth camera push-in focusing on [FEATURE], maintain focus"

Morph (Color/style change)

Start: Product in color A End: Product in color B Prompt: "Seamlessly morph product color from [A] to [B], maintain form"

---

Quality Settings

For High-End Results

• Resolution: 1920x1080 minimum (4K for high-DPI)
• Format: WebP (compression) or PNG (quality)
• Frame count: 90-150 frames (3-5 seconds at 30fps)
• Total size: Target <50MB for all frames combined

Optimization Tips

1. Use WebP format (70% smaller than PNG)
2. Compress with quality 85-90
3. Resize images to max 2000px width
4. Use consistent aspect ratio (16:9 or 1:1)

---

Testing Checklist

• Background color matches exactly (no visible edges)
• All frames same dimensions
• Smooth motion (no jumps between frames)
• Consistent lighting across sequence
• File names sequential (frame_0001 to frame_0120)
• Total file size reasonable (<50MB)
