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 shared data blobs, the higher ceiling also benefits competing clients — Bluescreen, Reelo, and Skylight. The 10-minute cap matches TikTok and doubles Threads' five-minute limit.
