What is it?
An open-source library for processing and transforming videos.
Why did we choose it?
It's open source, well maintained, and extremely powerful.
What do we use it for?
Resizing and re-encoding user video uploads for fast previewing within the artwork submission forms. We use FFmpeg to create a video containing the first 10 seconds of the original video, allowing for easy previews whilst not taking ages to finish processing.
