Need AI Video Editing Expert to Build Automatic High-End Editing System for HeyGen Videos

I am looking for a professional AI Video Editing Expert who can help me convert my raw HeyGen voice-over videos into top-level, high-impact, cinematic Instagram/Reel videos using AI-based tools.
The goal is NOT manual editing.
I want a fully automated or semi-automated AI system where I can paste my script or upload my raw video, and the system automatically:
Adds motion
Adds documentary-style visuals
Adds B-roll, overlays, text, transitions
Matches visuals exactly with my script

Scope of Work
Analyze my raw HeyGen output (talking avatar + voice-over)
Design an AI-based editing workflow that:
Auto-adds B-roll & visuals based on script
Adds smooth motion, zooms, pans
Adds animated captions & highlights
Applies cinematic/documentary style
Tools may include (but not limited to):
AI video editors
AI B-roll generators
Auto-caption & motion tools
Setup end-to-end process:
Script → HeyGen → AI Editing → Final Reel
Teach me the entire system step-by-step so I can edit videos myself
Provide:
Tool list
Presets
Prompts
Templates
Screen-recorded training

Editing Style Required
High-end Instagram / Reels quality
Fast-paced, modern, premium look
Documentary + explainer feel
Smooth motion & dynamic visuals
NOT basic CapCut edits

Deliverables
1 complete AI editing system/workflow
Ready-to-use templates & presets
Training videos + documentation
1–2 sample edited videos as demo
