Open Generative AI Guide

What Open Generative AI is

Open Generative AI (OGA) is a free, open-source creative studio for image, video, audio, lip sync, and cinema workflows. It supports 200+ models — Flux, Kling, Veo, Wan, LTX, and others — through a single self-hosted interface. You can run inference locally, route to your own API keys, or use hosted endpoints without platform guardrails or per-seat markup.

Use this when you want a unified production desk instead of juggling five separate SaaS tabs.

Choose your setup path

| Path | Best for | Requirements |

|------|----------|--------------|

| Hosted (muapi.ai) | Fastest start, no GPU | Free account, browser only |

| Self-hosted Docker | Full control, your keys | Node.js 18+, Docker optional |

| Local GPU stack | Zero per-gen fees | NVIDIA 12GB+ VRAM, CUDA |

Start hosted to learn the studios. Move self-hosted when volume justifies it.

Self-host install

git clone https://github.com/ncsound919/Generative-Video-AI.git
cd Generative-Video-AI
npm install
cp .env.example .env
npm run dev

Open http://localhost:3000. Add API keys in Settings for the providers you use (Replicate, Fal, OpenRouter, etc.).

Studio map

| Studio | Use case |

|--------|----------|

| Image | Text-to-image, img2img, multi-reference (up to 14 images) |

| Video | Text-to-video, image-to-video, motion control |

| Cinema | Photoreal shots with lens, focal length, aperture controls |

| Lip Sync | Portrait animation driven by audio |

| Workflows | Chain image → video → upscale in one pipeline |

| Agents | Multi-step creative tasks with tool use |

Cinema workflow (step by step)

1. Script the shot — one sentence: subject, action, mood, camera move
2. Generate keyframe — Image studio, Flux or Seedream, 16:9 aspect
3. Animate — Video studio, image-to-video with Kling, Veo, or LTX
4. Extend — Smart-continue or last-frame chaining for longer clips
5. Upscale — Export at 720p/1080p, run through Real-ESRGAN or Topaz if you need 4K
6. Audio — Lip sync studio or external DAW for VO and music

Prompt template for cinematic shots

[Subject] [action] in [environment].
Lighting: [golden hour / neon / soft box].
Camera: [35mm / 85mm], [wide / medium / close-up].
Movement: [static / slow dolly / orbit].
Mood: [tense / warm / documentary].
Avoid: text overlays, warped hands, flicker.

Model selection cheat sheet

| Need | Start with |

|------|------------|

| Fast iteration | Flux Schnell, SDXL Turbo |

| Hero still | Flux Pro, Seedream |

| Human motion | Kling, Runway |

| Physics / lighting | Veo, Luma |

| Long clips | LTX-2, chained segments |

| Lip sync | Infinite Talk, LTX Lipsync |

Production checklist

• Keyframe approved before burning video credits
• Consistent aspect ratio across sequence (16:9 or 9:16)
• Reference images locked for character continuity
• Audio synced in post if not using lip-sync studio
• Exports named: project_scene_take_v01.mp4

Cost control

• Generate stills cheap; animate only approved frames
• Batch similar prompts — model warm-up wastes less time
• Self-host routing: you pay API providers directly, no middleman markup
• Cache seeds and prompts in a project folder for reproducibility

Complementary local tools

For GPU-heavy local work, pair OGA with:

• ComfyUI — node-based workflows for LTX-2 and custom pipelines
• Milimo Video — AI-native NLE with timeline editing
• FFmpeg — concat, trim, format conversion

Troubleshooting

| Issue | Fix |

|-------|-----|

| Model timeout | Reduce resolution; switch to faster model tier |

| Character drift | Lock reference images; lower denoise on img2img |

| Jerky motion | Shorter clips; use last-frame continuation |

| API errors | Check .env keys; verify provider quota |
