+MyAvatar delivers cinema‑quality video background replacement with a production pipeline:
+1) First‑frame analysis
+2) SAM2 segmentation (Meta)
+3) MatAnyone professional video matting (CVPR 2025)
+4) High‑fidelity compositing with your chosen background
+
+This Space is a lightweight UI that calls a backend worker for heavy processing, ensuring fast builds and a responsive demo.
+
+## How to use
+- Upload a short MP4 (≤30s recommended for demo)
+- Choose/provide a background image URL
+- Click Process — the Space sends the job to your backend and shows progress
+- Download the processed result
+
+## Configure
+Set Space Secrets (Settings → Variables):
+- BACKEND_API_URL: https://your-backend.example.com
+- AUTH_TOKEN: optional “Bearer ...” if your backend requires it
+- DEFAULT_BACKGROUND_URL: optional fallback image
+
+## Why decouple UI and compute?
+- Faster, reliable Space builds (no large model installs here)
+- Heavy GPU/CPU workloads run on your backend or a dedicated worker
+
+## Requirements
+Keep requirements minimal for quick builds:
+- gradio==4.44.0
+- requests>=2.31.0
+- python-multipart>=0.0.9 (if server receives uploads)
+
+If you process media locally in this Space, add apt.txt:
+- ffmpeg
+- libgl1
+- libglib2.0-0
+
+## Troubleshooting
+- Match sdk_version to the gradio version in requirements
+- Avoid git+ and torch installs in this Space; run models on the backend
+- If uploads fail, test with smaller clips first, then tune backend timeouts
+
+Built with ❤️ by MyAvatar — production‑ready and scalable.
