About This Repository

This repository contains Python implementations of VSD(Video Storage in DNA). It mainly includes the following functions:

1. Video segmentation.
2. DNA encoding and decoding.

Experimental steps

Video Segmentation

Step 1: Open segmentation.py script(Confirm that you have installed ffmpeg);

Step 2: Choose a mp4 file, and set the output path & srgment duration;

Step 3: Run the script, it will will quickly complete video segmentation, and each video can be played separately.

DNA Encode

Step 1: Open VSD_codec.py script, drop down to line 250;

Step 2: Choose a mp4 segmentation file, and set the DNA file output path;

Step 3: Run the script,It will automatically perform a quaternary conversion and output a DNA sequence file in fasta format.

DNA Decode

Step 1: Open VSD_codec.py script, drop down to line 250;

Step 2: Choose a mp4 segmentation file, and set the DNA file output path;

Step 3: Run the script,It will automatically perform a quaternary conversion and output a DNA sequence file in fasta format.
