Key takeaways
- Instagram’s publishing API works only with professional (Business or Creator) accounts.
- A Reel must be MP4 or MOV, 3 seconds to 15 minutes, up to 300 MB and at most 1,920 pixels wide, per Meta.
- Instagram processes each Reel after upload; SkedCast waits for it and shows Instagram’s reason if it fails.
- A Reel always needs a video: there is no text-only or image-only Reel.
Why can’t you schedule a Reel on Instagram?
Start from the post itself: its detail sheet on the Calendar, or the Failed list, shows the reason Instagram gave.
Which Instagram accounts can schedule Reels?
Professional ones. Instagram’s publishing API works with Business and Creator accounts, connected through Meta’s login: sign in with Instagram or Facebook, then pick the account. A personal account cannot be connected for any post type, so switch it to a professional account in the Instagram app first; it is free and takes a minute.
What video does Instagram accept for a Reel?
Most failures are a long or oddly shaped source file. Check it with the media spec checker or the Reel length checker before you upload.
What happens after a Reel is scheduled?
At the scheduled time SkedCast sends the video to Instagram, which processes it before it can be published. SkedCast checks until Instagram reports the Reel finished or failed; if it fails, Instagram’s own reason appears on the post so you can fix the file and retry. See the Instagram scheduler for covers, collaborators and every other Reel option.
Where to actually look
Every scheduled post lives on the Calendar (/calendar in the console) — a month/week grid you can filter by client, platform and status. Click a scheduled post there to open its detail sheet and see its exact status, target account and any error.
A post that failed validation before it was even queued shows up under Drafts (/posts/drafts) instead of the calendar, and a post that failed to publish after being queued shows up under Failed (/posts/failed) with the reason.
FAQ
- Does SkedCast actually support scheduling Instagram Reels?
- Yes. Reels publish through Instagram’s API like any other post; a single video defaults to a Reel in the composer.
- Can I schedule a Reel to a personal Instagram account?
- No. Instagram’s publishing API works only with a professional (Business or Creator) account, which you can switch to in the Instagram app. This applies to every post type.
- Why did my Reel fail during processing?
- Most often the video: a format, length, size or shape outside Instagram’s Reel specs. The failed post shows Instagram’s own reason.
- How long can a scheduled Instagram Reel be?
- Between 3 seconds and 15 minutes, and up to 300 MB, per Meta’s Reel specifications.
- What size should an Instagram Reel be?
- 9:16 is recommended, at most 1,920 pixels wide, for example 1080 × 1920.
- Can a Reel have a caption but no video?
- No. Every Reel on Instagram needs a video; there is no text-only or image-only Reel.
