Bluesky's 10-minute video upgrade extends to rival apps via AT Protocol

Bluesky raised its video limit to 10 minutes and 300MB on August 26, 2026, with uploads 2-3x faster. Because the AT Protocol stores media as blobs on shared Personal Data Servers, the raised default ceiling also benefits competing clients on the network — Bluescreen, Reelo, and Skylight — not just Bluesky's own app. The 10-minute cap matches TikTok and doubles Threads' five-minute limit.
