AI-Based Automated Video Creation System Developer

Looking for a developer to build an AI-based automated video creation system.

IMPORTANT:
I will provide the initial UI/UX draft in Figma after we confirm the structure.
If additional screens are needed, we will discuss and update.
You handle backend logic + AI workflow + integrations.

All steps below must be fully automated (n8n, custom pipeline, or your own solution).
Scheduling must also be supported.

Required Features:
1. Script generation (must allow me to modify training/prompt logic later)
2. Auto subtitle generation (Whisper or API)
3. Thumbnail generation (AI image)
4. SNS auto posting (YouTube/TikTok/Reels if possible)
5. Free stock footage search based on script keywords
6. Automatic B-roll selection from free footage
7. Ability to generate long videos (up to 1 hour+)
8. Template system
9. Automatic scene recognition + auto cutting
10. AI voice generation
11. Final video rendering (ffmpeg or similar)
12. Full automation of ALL steps + scheduling
13. Error handling + retry logic
14. Clear backend structure so I can update prompts/workflows

Conditions:
– After scope is agreed, no extra charges later.
– Only apply if you have experience with video automation, ffmpeg, AI tools.
– Automation workflow experience (n8n/Make/Zapier/custom pipelines) required.

Budget: $100–$150 (fixed)
Timeline: 7–10 days (flsible)
Portfolio of similar video automation work required.
