Not entirely by choice 🥲 Plebs uploads the videos across numerous Blossom hosts, which most only support 100mb uploads. It's for good reason, as the hash generation would take an enormous time for larger files. Luckily, Plebs does have some auto compression that might work, but would suggest trying to compress it yourself first, if possible. Decentralization isn't always the best, but at least your video is spread across multiple hosts and if one goes down, the hash is used to fetch it from another.
