Fix Instagram Reels video format issues in Repostit explains what to check when a Repostit workflow reaches Instagram Reels but does not behave the way you expected.
This guide is for Repostit users working with TikTok, YouTube Shorts, Facebook Reels, and Instagram Reels, which are the platforms currently covered by the public Repostit help center.
Why format matters #
Instagram Reels may expect a certain video shape, length, or file format.
A file that worked on one platform can still be rejected or perform poorly on another.
What to do next #
- Use vertical video for Reels and Shorts workflows.
- Avoid files that are too long for the destination format.
- Review the destination platform’s latest upload limits.
- Test a small batch before enabling the workflow broadly.
What to send support #
- The source platform and destination platform.
- The account or page you expected to publish to.
- The approximate time the workflow ran.
- A screenshot of the error, if Repostit or the social platform showed one.
Platform-specific checks #
Instagram Reels checks #
- Instagram authorization should be approved from the account that owns the Reels workflow.
- Check crop-safe areas because captions, overlays, and profile UI can cover parts of a Reel.
- If Instagram opens the wrong profile, sign out in the browser and reconnect from Repostit.
Practical check #
- Keep the first version simple enough that you can verify it quickly.
- Write down the source account, destination account, and reason for the workflow.
- Review the first result on the destination platform before increasing posting volume.
Quality bar before you rely on this #
Before you treat this as a live Repostit workflow, publish one low-risk test and inspect the result on Instagram Reels. A workflow is ready only when the correct source account, destination account, video format, and permission path all match what you expected.
If this is for a client or brand account, write down the source, destination, approval owner, and reason for the workflow. That small note prevents confusion later if someone asks why a post appeared on a specific channel, Page, or profile.
