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

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
