🧠 Introduction

As part of my ongoing archival work for the Kapothi Vault, I needed to convert a legacy DVD video disc into two formats:

• A single .mp4 file preserving the original video quality
• A single .mp3 file extracted from the DVD’s audio stream

This post documents the exact steps I followed using FFmpeg, a powerful open-source tool for multimedia processing.

📀 Step 1: Copy DVD Contents to Hard Disk

I first copied the entire DVD to a folder on my hard drive. The DVD structure looked like this:

D:\DVDVIDEO\
└── VIDEO_TS\
    ├── VTS_01_1.VOB
    ├── VTS_01_2.VOB
    ├── VTS_01_3.VOB
    └── ...

🎬 Step 2: Convert Full DVD to MP4 (Preserving Quality)

To combine all .VOB files into a single .mp4 file, I created a text file named voblist.txt with the following content:

file 'VTS_01_1.VOB'
file 'VTS_01_2.VOB'
file 'VTS_01_3.VOB'

Then I ran this FFmpeg command:

ffmpeg -f concat -safe 0 -i voblist.txt -vf yadif -c:v libx264 -preset slow -crf 18 -c:a aac -b:a 192k "DVD_Archive.mp4"

✅ What this does:

• Combines all listed .VOB files
• Deinterlaces the video (yadif)
• Compresses with high-quality H.264 (libx264)
• Preserves near-original quality (crf 18)
• Converts audio to AAC at 192 kbps

🎵 Step 3: Extract Audio as MP3 from Main VOB File

To extract just the audio from the main .VOB file, I used:

ffmpeg -i "VTS_01_1.VOB" -vn -c:a libmp3lame -b:a 192k "DVD_Audio.mp3"

✅ What this does:

• -vn disables video
• Converts audio to MP3 using LAME encoder
• Preserves audio fidelity at 192 kbps

🕊️ Final Thoughts

This process ensures that legacy DVDs are not just digitized, but ritualized — with every frame and waveform preserved in formats that honor their original structure. Whether you’re archiving family memories or regional media, FFmpeg remains a sovereign tool in the Kapothi arsenal.
