How Can I Safely Store a Video in a Time Capsule for 50 Years?

We’ve already lost access to some media from the 80s, so even if your DVD lasts until 2075, it’s hard to predict if there will still be devices compatible with it. You might be better off going for something extremely accessible, like having a camera with the video loaded directly onto it, along with a USB charger.

Honestly, I think a QR code might not be the way to go since it depends on future people knowing what to do with it. You've got a lot of factors to consider: the platform that hosts the video has to exist and be reachable, plus there’s no guarantee that the format will be playable 50 years from now. A more reliable option could be storing a physical movie reel. People will always be able to project that no matter what happens to technology!

I'd recommend making a DVD on an M-Disk since they are designed for long-term storage and include a USB drive as a backup. Plus, it’s smart to include various formats of the video for flexibility. If you can have two copies, do one standard DVD and one data disk. This way, future viewers can use an adapter to access the files, ensuring higher chances technologies evolve to read them later.

You might want to look into archival quality DVDs. Not all so-called 'archival' disks are equal, so do your research! For best results, store it in a sturdy, waterproof metal container that's clearly labeled, and include a detailed description of the contents inside. Make sure to avoid plastic foam for padding as it can break down over time. If it’s a DVD, clarify that it is one, as future tech might confuse it with other outdated formats.

If you're leaning into physical media, consider putting along a player that can read whatever format you choose. Think about how many businesses that were around 50 years ago are still in operation today. If you go the online route, you’ll need to ensure ongoing funding and maintenance for that website to keep it active for the next five decades!
