Checked: October 17, 2026

Up to 10 minutes since August 2026, up from 3. Files can be up to 300 MB, one video per post, and you need a verified email. Drag the slider to check a length.

## The short answer: Bluesky videos: up to 10 minutes and 300 MB.

Since August 25, 2026, Bluesky takes videos of up to 10 minutes, up from 3. The file can be up to 300 MB since June 2026. Each post holds one video, and Bluesky-hosted accounts need a verified email to upload.

Apps and schedulers upload to the same video service, and the post format allows the same 300 MB. Bluesky set a daily cap of 25 videos or 10 GB when video launched and said it may change it; the API reports each account's remaining allowance. Bluesky publishes no ideal length.

- **Longest video**: 10 min (Since August 2026, was 3 minutes)
- **File size**: 300 MB (Since June 2026, was 100 MB)
- **Per day**: 25 videos (Or 10 GB, Bluesky's launch figure)

## Drag to your video's length and see where it fits

| Video (API) | 0:01 | 10:00 |  | Bluesky's post format and video service, which apps and schedulers use: the same 10 minutes and 300 MB. |
| Via OmniSocials | 0:01 | 10:00 |  | OmniSocials checks Bluesky video against Bluesky's 10 minutes and 300 MB. |

## Every Bluesky video limit in one table. In the app and through the API.

| Limit | Bluesky app | Through the API |
|---|---|---|
| Length | 10 minutes | 10 minutes |
| File size | 300 MB | 300 MB, stored as MP4 |

| Captions | 1 subtitle file (.vtt) | Up to 20 files, 20 KB each |
| Alt text | 2,000 characters | No cap in the post format |
| Email | Must be verified | Must be verified |

From Bluesky's announcements, its post format (app.bsky.embed.video), its open-source app and its developer docs, read on October 17, 2026. OmniSocials checks Bluesky video against the same 10 minutes and 300 MB.

## Do video posts get more interactions? A little, in one 2025 dataset.

| Format | Median interactions per post |
|---|---|
| Video | 5 |
| Photos | 4 |
| Links | 3 |
| Text only | 3 |

Buffer, published March 2026, 2025 data. Interactions are likes, replies and reposts. No study gives a best video length for Bluesky.

## What changed for video length. From 60 seconds to 10 minutes in two years.

- **Aug 2026: 10-minute videos** Bluesky announced you can now "post videos up to 10 minutes long", with uploads 2 to 3 times faster. (https://bsky.app/profile/bsky.app/post/3mtwf7gxkwc2r)
- **Jun 2026: 300 MB files** Bluesky "bumped the video upload limit from 100MB to 300MB". (https://bsky.app/profile/bsky.app/post/3mni6hmaff22u)
- **Jul 2025: Higher-resolution video** Bluesky said videos posted on Bluesky are now higher resolution. It publishes no resolution number. (https://bsky.app/profile/bsky.app/post/3lv2nr32whs2m)
- **Mar 2025: 3-minute videos** Version 1.99 raised the limit from 60 seconds to 3 minutes. (https://bsky.app/profile/bsky.app/post/3lk26lxn6sk2u)

## Get your video posted. Most failures are the email, the size or the daily cap.

1. **Verify your email first** Bluesky-hosted accounts cannot upload video without a verified email. Check it in Bluesky's account settings.
2. **Keep the file under 300 MB** A 10-minute video fits at about 4 Mbps. Export at a lower bitrate if your file is bigger.
3. **Add a subtitle file** The app takes one .vtt file per video. Many people watch with the sound off.
4. **Write alt text** Videos take alt text up to 2,000 characters in the app, the same as photos.
5. **Mind the daily cap** Bluesky set 25 videos or 10 GB a day at launch. Space out big uploads if you post a lot of video.
6. **Add alt text to every video** Bluesky takes alt text on videos. It helps people who use screen readers, and OmniSocials sends it with the post.

## Sources and method

The limits come from Bluesky's own posts, its post format (the app.bsky.embed.video lexicon), its open-source app and its developer docs, read on October 17, 2026. The daily cap is Bluesky's figure from the September 2024 launch, which Bluesky said it may change. No study gives a best length for Bluesky videos, so the page shows none.
