Fix Instagram Error: One Video Uploads but Others Fail

Understanding Instagram’s Video Posting Formats
Instagram supports several content formats, each with unique requirements. Knowing these can prevent upload errors:
- Reels – Short-form vertical videos up to 90 seconds (most regions), optimized for discovery.
- Feed Videos (Single) – Landscape or portrait videos as standalone posts.
- Carousel Posts – A swipeable series of up to 10 media items (photos and/or videos).
- Stories – Temporary media visible for 24 hours.
The problem where only one video uploads in a carousel often stems from mismatched file specifications or uneven network performance.

Common Reasons Why Only 1 Video Posts and Others Fail
Multiple video uploads may fail due to:
- Excessive File Size – Limit is ~4GB per video.
- Unsupported Formats – Non‑compliant formats can cause processing failures.
- Codec Mismatch – Different video/audio codecs in the same carousel can block uploads.
- Unstable Internet – Drops in connection during upload stop the process.
- Outdated App – Older versions may have known bugs.
- Content Restrictions – Community guideline or copyright violations.

Check Video File Specs Before Uploading
Always confirm each file meets Instagram’s current upload requirements:
| Parameter | Recommended | Acceptable Range |
|---|---|---|
| File Format | MP4 (H.264, AAC) | MP4, MOV |
| Resolution | 1080 × 1920 px (vertical) | 320 × 566 px up to 1080 × 1920 px |
| Aspect Ratio | 9:16 (Reels) / 1:1 (Square) / 4:5 (Portrait) | 1.91:1 to 9:16 |
| Frame Rate | 30 FPS | Up to 60 FPS |
| Max File Size | < 4GB | Hard limit ~4GB |
Pro Tip: Even minor aspect ratio differences between clips can block a carousel upload.
How to Check File Specs
- Mac: Right‑click → Get Info
- Windows: Right‑click → Properties → Details tab
- Mobile: Use apps like InShot, KineMaster, or Video Converter

Troubleshoot Internet Connectivity
A strong, stable internet connection is essential:
Try:
- Switching from mobile data to a strong Wi‑Fi signal.
- Restarting your modem/router.
- Uploading during off‑peak hours.
- Pausing large background downloads.
Also, close unused apps to free up system resources for Instagram uploads.

Update the Instagram App and Clear Cache/Data
Outdated apps can cause recurring failures.
iOS:
- Open the App Store.
- Search Instagram.
- Tap Update if available.
Android:
- Go to Play Store.
- Search Instagram and Update.
- Clear Cache/Data:
- Settings → Apps → Instagram → Storage → Clear Cache (and Clear Data if needed).
---
Split or Compress Videos to Meet Limits
If uploads fail due to size or length:
- Split: Divide long clips into multiple shorter segments using apps like CapCut or Adobe Premiere Rush.
- Compress: Reduce bitrate or slightly lower resolution to cut file size without major quality loss.
Make sure all clips share:
- The same aspect ratio
- Matching codecs
- Similar frame rates
---
Try Instagram’s In‑App Camera
Recording inside Instagram ensures compliant encoding and compression.
Pros:
- Guaranteed format compatibility
- Quick publishing
- Minimizes third‑party processing glitches
Cons: Pre‑recorded videos offer more creative control—just ensure they conform to Instagram’s specs before uploading.
---
Test on Another Device or Network
To isolate the root cause:
- Try uploading from a different phone/tablet.
- Switch to another internet network.
- Test on Instagram’s desktop site.
This can reveal whether the issue lies with your device, your network, or Instagram itself.
---
Avoid Copyrighted or Blocked Content
Instagram may block uploads if content contains copyrighted music or restricted media.
Avoid issues by:
- Using Instagram’s audio library
- Opting for royalty‑free tracks
- Replacing blocked clips before upload
Remember: one blocked clip can stop the entire carousel from posting.

Contact Instagram Support
If nothing works, escalate the issue:
- Go to Profile → Settings → Help → Report a Problem.
- Provide a clear description—e.g.,
- “1 video posts but multiple videos don’t post on Instagram.”

Schedule Multiple Videos via Creator Studio or Third‑Party Tools
Desktop uploading tools like Facebook Creator Studio, Buffer, or Later can help:
Benefits:
- Stable wired internet
- Batch uploads and previews
- Better control over formatting
Note: Third‑party apps must follow Instagram’s API limits.

To improve upload success rates:
- Standardize format, resolution, and codec across all media.
- Maintain a strong internet connection.
- Post during off‑peak times.
- Update the app regularly.
