+# How to Create Videos Like the Demo (52 seconds in just 736kB!)
+
+The demo video showcases Abogen - an all-in-one tool for turning text into something you can see and hear. This guide explains how I created such a small yet effective demonstration video.
+
+## About the Demo
+
+The demo video shows how Abogen:
+- Converts text files (ePub, PDF, text) into audio with synchronized subtitles
+- Uses Kokoro (a powerful text-to-speech engine) to create natural voices
+- Works completely on your computer for privacy and security
+- Offers an easy interface for creating audiobooks and voiceovers
+- Can be used for Instagram, YouTube, TikTok, or any content creation
+
+And it does all this while being only **736kB** for a **52-second video**!
+
+## How I Created This Tiny Video
+
+### What You Need
+
+- A background image (bg.jpg)
+- The subtitle file (.srt) created by Abogen
+- The audio recording (.wav) created by Abogen
+- FFmpeg installed on your computer:
+
+```bash
+# Windows
+winget install ffmpeg
+# MacOS
+brew install ffmpeg
+# Linux
+sudo apt install ffmpeg
+```
+
+### Step 1: Process the Subtitle File
+
+Run this command to process Abogen's subtitle file:
+
+```
+python convert.py abogen_subtitles.srt
+```
+
+This creates a properly formatted subtitle file called "abogen_subtitles_demo.ass" with centered text and appropriate styling.
+
+### Step 2: Create the Video
+
+Run this FFmpeg command to create the tiny video:
+
+```
+ffmpeg -loop 1 -framerate 24 -i bg.jpg -i audio.wav -vf "ass=abogen_subtitles_demo.ass" -c:v libvpx-vp9 -b:v 0 -crf 30 -c:a libopus -shortest demo.webm
+```
+
+That's it! The magic happens because:
+- We use a single static background image instead of many frames
+- The subtitles are stored as text (vector data), not as pixels
+- VP9 video codec with Opus audio provides excellent compression
+
+## For Higher Quality (But Larger) Video
+
+If you need better quality for distribution, use this command instead:
+
+```
+ffmpeg -loop 1 -framerate 24 -i bg.jpg -i audio.wav -vf "ass=abogen_subtitles_demo.ass" -c:v libx264 -preset slow -crf 18 -movflags +faststart -c:a copy -shortest demo.mp4
+```
+
+This creates an MP4 file that's compatible with more devices but larger in size.
