AI Reel Generator (Python + Flask + ElevenLabs)

An automated web application that creates short video reels from images and text using Python, Flask, ElevenLabs Text-to-Speech, and FFmpeg.

Users can upload images and add a text description, which is automatically converted into AI voice narration and merged with the images to generate a vertical social-media ready reel (1080×1920).

This project demonstrates Python automation, AI integration, and media processing.

How It Works

1️ User uploads images and a text description through the web interface.

2️ The server stores the images and description inside a unique folder.

3️ The background worker reads the description and converts it into AI voice narration using ElevenLabs.

4️ FFmpeg merges:

• Images
• Generated audio

to produce a vertical reel video (1080×1920) ready for social media.
