📝 Step-by-Step Tutorial
Step 1: Brainstorm Concepts and Generate Prompts with ChatGPT [Timestamp: 01:21]
Open ChatGPT and paste the creator Master Prompt. The prompt directs ChatGPT to act as a cinematic miniature construction director. Review the table of 10 clickable project ideas, choose your preferred build (such as Idea #1), and let ChatGPT output the First Frame Image Prompt followed by the four sequential 8-second construction video prompts.

Style For Miniature Construction
Act as an Elite AI Video Production Strategist, Cinematic Miniature Construction Director, Master Prompt Engineer, and Viral Content Creation Expert specializing in hyper-realistic miniature DIY construction videos. Your task is to generate a complete AI-powered workflow for creating highly satisfying miniature construction timelapse videos with seamless visual continuity, realistic craftsmanship, cinematic macro photography, and professional construction progression. Follow the workflow exactly as instructed.
### PHASE 1: 10 HIGHLY CLICKABLE VIRAL IDEAS
Generate 10 highly clickable, SEO-optimized YouTube video titles based on the chosen miniature construction niche. They must be curiosity-driven with high CTR potential, including viral words like Miniature, DIY, Construction, Timelapse, Building, Tiny House/Farmhouse.
Format Phase 1 as a clean table:
| # | Video Title (SEO & CTR Optimized) | Cinematic Audio & Sound Effects Vibe | Visual Setup & Miniature Materials Used | Core Satisfying / Viral Element |
Stop and wait at the end of Phase 1. Ask: "Please select one of the ideas by replying with its number (1-10) so I can generate the First Frame Image Prompt and 4 Continuous Construction Motion Prompts." Do NOT proceed to Phase 2 until the user selects an idea.
---
### PHASE 2: THE DETAILED SCENE-BY-SCENE PRODUCTION BLUEPRINT (8 SECONDS PER SCENE)
Once I select a number, break it down into exactly 1 First Frame Image Prompt and 4 sequential chronological Motion Prompts to build the complete miniature construction timelapse with seamless continuity. Each scene is precisely 8 seconds long.
CRITICAL OUTPUT FORMAT CONSTRAINT FOR EACH STEP:
- Scene 1 MUST contain TWO separate code blocks. The first block must be explicitly labeled "Image Prompt", and the second block must be explicitly labeled "Video Prompt".
- Scenes 2, 3, and 4 must ONLY have ONE single code block explicitly labeled "Video Prompt", since they rely entirely on extending the last frame of the previous step.
GLOBAL RULES FOR ALL MOTION PROMPTS:
Every motion prompt MUST include: "ultra fast timelapse speed", "8 seconds duration", and "human hands continuously constructing and moving rapidly". Additionally, every motion prompt must include multiple rapid scene cuts, dynamic construction progression, visible material placement, realistic hand movements, miniature tools actively used, satisfying construction transformations, cinematic macro photography, and ultra-realistic textures. No unfinished phase at the end of the clip; the construction phase shown in that prompt must be fully completed before the clip ends.
Follow this exact structure for Phase 2:
**Scene 1: FOUNDATION & BASE CONSTRUCTION (0-8 seconds)**

Step 4: Extract End-Frames and Chain Scenes 2 to 4 [Timestamp: 03:20]
To prevent the miniature house from morphing between cuts, navigate to the final second of Scene 1 and click the 'Save Frame' button to capture the exact ending frame. Use this saved frame as the start frame for Scene 2, apply the Scene 2 prompt, and generate. Repeat this exact process for Scene 3 (Roofing & Painting) and Scene 4 (Landscaping & Final Reveal).
Prompt / Settings:
PROMPT / SETTINGS
Model: Omni Flash
Aspect Ratio: 9:16
Duration: 8 seconds
Reference Input: Saved last frame from previous scene
Sample Continuation (Scene 2): Ultra fast timelapse speed, 8 seconds duration. Human hands continuously constructing and moving rapidly. Multiple rapid cuts show first wall sections rising, brick stacking, cement application, window openings being formed, doorway creation, structural wall completion, followed immediately by wooden roof trusses installation and beam placement. Walls and roof framing become fully completed with all openings finished before the clip ends.
Step 5: Assemble and Edit in CapCut [Timestamp: 04:05]
Download all 4 generated video clips from Google Flow and import them into CapCut. Arrange them in sequential order (Foundation, Walls/Frame, Roofing/Paint, Landscaping/Reveal). Trim dead frames, tighten transition cuts, and layer satisfying tactile sound effects (scraping mortar, brick clicking, paint strokes) over an upbeat acoustic or lofi background track before exporting in 1080p.
💡 Key Takeaways & Pro Tips
- Never Skip End-Frame Chaining: Generating each scene without anchoring to the exact ending frame of the previous clip causes tools, wall dimensions, and brick colors to morph noticeably.
- Use Texture-Specific Models: Utilizing Nano Banana 2 for the initial base image ensures brick textures, ground soil, and hand details render with macro realism before animation begins.
- Enforce Construction Completion in Prompts: Ensure every motion prompt explicitly dictates that the phase finishes before the 8-second clip ends, preventing awkward cutoffs in the build.
