I recorded lots of television in the mid to late 2000s. Most of it was advertising for my sister’s media course, but also lots of one off stuff.

Incidently, I blogged about the Elgato TV Tuner I used to do it, and it got my little blog here a mention on the company’s press page. Pretty cool, I thought.

Fast forward almost a decade later, and I found a ton of these old recordings on a backup drive. I didn’t have the heart to delete them, so I re-encoded them with avconv in as h264/aac to shave close to 90% of their space with no discernable difference in quality.

Running it through ffmpeg, I noticed something interesting. Each of these files had metadata, rught down to the original digital broadcast stations! Here was a file recorded from Channel 9:

I wonder if those stations still exist, or with the same names, now?
