# Video Steganography

[![Build Status](https://travis-ci.com/Amritaryal44/Video-Steganography.svg?branch=master)](https://travis-ci.com/Amritaryal44/Video-Steganography)

Hide Your secret videos inside any other videos.
### Example
| Cover video where secret video is to be hidden | Secret Video to be hidden |
|:--:|:--:| 
| ![Cover Video](https://raw.githubusercontent.com/Amritaryal44/Video-Steganography/master/img_md/v1.gif) | ![Secret Video](https://raw.githubusercontent.com/Amritaryal44/Video-Steganography/master/img_md/v2.gif) |

| ![Encrypted Video](https://raw.githubusercontent.com/Amritaryal44/Video-Steganography/master/img_md/encrypted.gif) | ![Decrypted Video](https://raw.githubusercontent.com/Amritaryal44/Video-Steganography/master/img_md/revealed.gif) |

### Features

- Supports video of any aspect ratio
  - Encodes audio along with video

Please ensure:
  - Secret video files must have less frame count then that of cover video
  - We will lose Audio quality and audio of secret video may be noticeable even after encryption [ Currently working for it ]
  - ffmpeg  needs to be installed and should be available in shell command
  - Encrypted video should not be converted into any other forms because we don't want to compress the video to preserve the secret data
