Bluesky Video Limits Explained

Bluesky didn't launch with video at all. When the network opened to the public in February 2024 it was text and images only, and video posts didn't show up until September 2024. Since then the rules have loosened up a fair bit, but there are still hard caps on how long a video can run, how big the file can be, and how many you can post in a day.

This post breaks down all the Bluesky video limits as of 2026. And if you're on the other side of things, saving videos rather than posting them, we'll cover what these limits mean for download quality too.

How long can a Bluesky video be

The Bluesky video length limit is currently 3 minutes, or 180 seconds. It didn't start out that way. When video first arrived in September 2024, clips were capped at just 60 seconds, which felt tight even by short-form standards. Bluesky tripled the limit to 3 minutes in March 2025, and that's where things still stand.

If your clip runs longer than 3 minutes, you have two real options. Trim it down before posting, or upload it to a site like YouTube and share the link on Bluesky instead. There's no setting buried in the app that gets you extra time.

The Bluesky video size limit

File size is the limit that catches most people off guard. When video launched, uploads were capped at 50MB. As of mid 2026, the Bluesky video size limit sits at 100MB, which makes sense given the longer 3 minute duration. Some error messages and older help pages around the web still quote the old 50MB figure, so ignore that one if you run into it.

In practice, 100MB is roomy. A 3 minute clip at 1080p with a normal bitrate lands well under that. If your file comes out bigger, your export settings are probably higher than they need to be, and Bluesky compresses everything on upload anyway.

Which video formats Bluesky accepts

Bluesky takes four file types: MP4, MPEG, WebM, and MOV. If you're not sure which to pick, go with MP4 using the H.264 codec. It's the most widely supported Bluesky video format, and it's what nearly every phone and editing app produces by default.

Format matters less than you might think, though. Whatever you upload gets re-encoded by Bluesky's video service before anyone sees it, so your choice mostly decides whether the upload is accepted, not how the final video looks.

Daily upload caps

There's also a Bluesky video upload limit per account: 25 videos or 10GB of video per day, whichever you hit first. This cap has been in place since video launched, and it exists to keep hosting costs sane on a platform that's free to use. Unless you're running a very busy media account, you'll never notice it.

One more small hurdle. If your account is hosted by Bluesky itself, you need a verified email address before your first video upload. Most people sort that out during signup without thinking about it.

What about video dimensions

Unlike length and file size, Bluesky video dimensions don't have a hard published rule. The common recommendation is 1920x1080 in 16:9, and that's a safe default for landscape footage. Portrait and square clips work fine too, the player simply fits them into the feed. Since everything gets compressed after upload, there's little point in exporting above 1080p.

What happens to your video after you post

Here's the part most people never think about. Bluesky doesn't serve your original file to viewers. Your upload goes to a dedicated video service, gets transcoded, and is then delivered from Bluesky's CDN as an HLS stream, the same chunked streaming tech most big video sites use. That's also why you can't just right-click a Bluesky video and hit save. The "file" is actually lots of small segments stitched together while it plays. GIFs on Bluesky are short looping videos under the hood, by the way, so they go through the same pipeline.

This matters when you find a video worth keeping. A proper downloader has to read that stream and rebuild it into a normal video file, and that's exactly what BskySaver does. Paste in a post link and it saves the highest quality version Bluesky stores, ready to watch anywhere.

Wrapping up

Quick recap: 3 minutes per video, 100MB per file, 25 videos or 10GB a day, and MP4, MPEG, WebM or MOV as accepted upload formats. Those are the Bluesky video limits in 2026, though Bluesky has raised them before and will probably do it again. And when a clip is worth keeping, head to bskysaver.com, paste the post link, and click Download. No signup needed, and it works right in your browser on any device.
