To schedule a Bluesky post with images or video, connect your account to a scheduler, attach up to 4 images of up to 1 MB each or one video of up to three minutes (not both), add alt text and pick a time. Bluesky has no built-in scheduler; SkedCast publishes through Bluesky’s API at the time you set.
Key takeaways
- Bluesky has no built-in scheduling; scheduled posts come from a tool using its API.
- A post holds up to four images of up to 1,000,000 bytes each, each with its own alt text, or one video.
- Videos can be up to three minutes long; images and video cannot be mixed in one post.
- Bluesky-hosted accounts must verify their email before posting video, and video posts have a daily limit.

Can you schedule Bluesky posts with images and video?
Yes, through a scheduler. Bluesky’s app has no option to post later, so a scheduled post is held by a tool and published through Bluesky’s API, the AT Protocol, at the time you set. Images and video both go through that API, so a scheduler that supports them can queue either.
What are Bluesky’s limits for images and video?
SkedCast checks every one of these before a post can be scheduled, so a 2 MB photo or a four-minute clip is flagged in the composer rather than failing at publish time. Check text length with the Bluesky character counter.
| Part | Limit |
|---|---|
| Text | Up to 300 characters |
| Images | Up to 4 per post, JPEG, PNG or WebP, up to 1 MB (1,000,000 bytes) each |
| Alt text | One description per image |
| Video | One per post, up to 3 minutes |
| Mixing | Images or a video, not both in one post |
| GIFs | Posted as a still image |
How do you schedule a Bluesky post with images or video?
The same steps work for threads and quote posts, and for one post sent to several Bluesky accounts at once. See how to connect Bluesky to SkedCast for the app-password setup.
Connect Bluesky
Connect your Bluesky account to SkedCast with an app password from Bluesky’s settings.
Add the media
Attach up to four images, or one video of up to three minutes.
Write alt text
Describe each image so people using screen readers know what it shows.
Pick a time
Schedule it; SkedCast uploads the media and publishes the post at that time.
What should you check before scheduling Bluesky video?
Two account rules from Bluesky. An account hosted by Bluesky must have a verified email before it can post video, and Bluesky limits how many video posts an account can make in a day. Video also needs time to process after upload; SkedCast sends it to Bluesky’s video service and waits for processing to finish before it posts. See the Bluesky scheduler for threads, quote posts and every other option.
