I had some media files I wanted to verify the integrity of -- I was using tdarr.io in a podman container on my local server. I then spun up an m7a.12xl spot instance, mounted my local storage to it via SMBv3. I ran tdarr on that instance, and connected it as a worker node to my home server instance. tdarr ran ffmpeg to decode every video frame to /dev/null, and reported any errors. It was able to process a few thousand FPS or about 2-3Gbps. I found some corrupted files, and was able to restore them from another backup.

There was no practical reason to do this, it cost about $100 to double my processing speed.
