Bluesky Video Length Tips
Videos are limited to 60 seconds
Bluesky currently caps video uploads at 60 seconds. This tight limit means every second counts. Plan and script your videos to deliver the full message within one minute.
Aim for 15-45 seconds for engagement
Within the 60-second cap, videos between 15 and 45 seconds perform best. This length is enough to share a thought or quick demonstration without overstaying its welcome.
Upload in MP4 format only
Bluesky currently supports MP4 video uploads only. Use H.264 encoding at 1080p for the best quality within the platform's file size constraints.
Keep files under 50MB
Bluesky has a strict 50MB file size limit for video uploads. Compress your 1080p video using efficient H.264 settings. A 60-second clip at 1080p can fit in 50MB with proper encoding.
Add alt text for accessibility
Bluesky supports alt text on video posts. Adding a brief description of your video content improves accessibility and helps your posts reach a wider audience.
