Compress Video to h265 recursively

This script compresses videos to h265 (HEVC) from one location to another recursively without overwriting the destination.

Features

  • Open Source bash script
  • Can run on Linux and Windows WSL
  • Can be run in a screen session in the background
  • Compress all videos in subfolders and copy folder structure to destination
  • No complicated switches
  • If terminated, can be restarted and will not overwrite already created files
  • Will not delete or overwrite any existing files
  • Will not recompress a source video that's already in h265 (HEVC) format.

Requirement

The script uses ffmpeg and can be install on Debian/Ubuntu based systems or Windows Subsystem for Linux (WSL) with:

~$ apt install ffmpeg

Windows users, to find out more regarding WSL, use this link.

Download/Install script

To download and use the script, do the following in a folder of your choosing:

~$ wget https://raw.githubusercontent.com/RiaanAspeling/CompressVideo/main/compress_video.sh
~$ chmod +x compress_video.sh

Now the script is ready to use. You could move the script to somewhere in your PATH if you'd like to access it from anywhere.

Usage

~$ ./compress_video.sh [-e EXTENSION] [-s SOURCE] [-d DESTINATION]
        -e EXTENSION        Mandatory: Specify the file extension to filter on source. Eg: -e mkv
        -s SOURCE           Mandatory: Specify the source folder to compress from. Eg: -s /mnt/myvideos
        -d DESTINATION      Mandatory: Specify the destination folder to compress to. Note that files 
                                       will not be overwritten. Eg: -d /home/user/myvideos

Example

Compress MKV videos from location /mnt/videos to ~/videos

~$ ./compress_video.sh -e mkv -s /mnt/videos -d ~/videos

The output might look like this:

Destination file exists: ~/videos/Season 1/video1.mkv
Destination file exists: ~/videos/Season 1/video2.mkv
Destination file exists: ~/videos/Season 1/video3.mkv
