video-convert

Bash script to convert a video to mp4 and webm

This script takes a list of inputs with filenames like "filename-1080p.mp4" and uses ffmpeg to convert them to the following formats (as applicable):

• 1080p mp4
• 1080p webm
• 720p mp4
• 720p webm
• 480p mp4
• 480p webm
• 360p mp4
• 360p webm

It maintains good quality for the resulting videos. Converting to webm will generally take a very long time.

Usage

video-convert FILE [FILE...]

The file names MUST end in -<height>p.<mp4|webm> as this is how this script determines the source resolution and container type.

This script converts to two formats:

• mp4 (h264/aac), which is non-free but widely supported
• webm (vp9/opus), which is free but less widely supported

It only converts to the same or lower height than the source. If you run video-convert myvideo-720p.mp4, for example, it will create the following files:

• myvideo-720p.webm
• myvideo-480p.mp4
• myvideo-480p.webm
• myvideo-360p.mp4
• myvideo-360p.webm
