Fix TikTok video format issues in Repostit explains what to check when a Repostit workflow reaches TikTok 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 #
TikTok 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 #
TikTok checks #
- TikTok can be sensitive to reused watermarks, so inspect the final post after the first workflow test.
- Check the sound on the TikTok post, especially if the original audio came from another platform.
- Keep the first few reposts simple before you use the workflow for a high-volume content run.
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 TikTok. 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.
