Reddit-TikTok Video Generator

THIS REPOSITORY IS OUTDATED AND POSSIBLY NON-FUNCTIONAL

Overview

This project automates the creation of Reddit-style TikTok videos, where an AI narrator reads a Reddit post while synchronized text appears on the screen, accompanied by a background video. The final product is a short-form, TikTok-style video generated with optimized rendering techniques

How It Works

1. Fetch Reddit Post: The script retrieves posts from Reddit using the Reddit API.
2. Determine Narrator Voice: A local Meta LLM (via Ollama) predicts whether the post author is male or female, selecting an appropriate voice.
3. Generate Narration: The post is converted to speech using either Amazon Polly (S3) or 11 Labs for higher-quality narration.
4. Generate Subtitles: The narrated MP3 file is transcribed into an SRT subtitle file using OpenAI's Whisper API.
5. Assemble Video:
   • Background video is selected.
   • Text animations synchronize with narration.
   • The final video is rendered using FFmpeg (previously MoviePy, but switched for better performance).
6. Output: A polished TikTok-style video ready for sharing.

Features

• Automated Workflow: Fully integrates APIs to automate video creation.
• Voice Selection by AI: Uses local LLM (Meta via Ollama) to determine an appropriate voice.
• Optimized Rendering: Uses raw FFmpeg for faster video production.
• Accurate Subtitles: Whisper API ensures high-quality transcriptions.
• Customizable Voices: Supports both Amazon Polly and 11 Labs voices.

Installation & Usage

Prerequisites

• Python 3.8+
• FFmpeg
• OpenAI API access
• Reddit API credentials
• AWS credentials for Polly
• 11 Labs API access
• Ollama for local LLM processing

Installation

# Clone the repository
