Why does Webflow show a "failed to upload background video" error message and how can I resolve it?

TL;DR
  • Ensure the video is MP4 format, under 30MB, and has a simple filename.
  • Compress large files using tools like HandBrake and convert non-MP4 formats with CloudConvert or VLC.
  • Try uploading in a different browser, incognito mode, or with a stable connection.
  • Reduce video resolution to 1080p or 720p if necessary.
  • If the issue persists, contact Webflow Support with relevant details.

The "Failed to upload background video" error in Webflow typically occurs due to file size, format, or upload restrictions. Follow these steps to troubleshoot and resolve the issue.

1. Check File Size

  • Webflow only supports background videos up to 30MB.
  • If your video exceeds this, compress it using HandBrake, VEED.io, or Adobe Media Encoder.

2. Verify File Format

  • Webflow only accepts MP4 videos.
  • If your file is in MOV, AVI, or WebM, convert it to MP4 using tools like CloudConvert or VLC Media Player.

3. Rename the File

  • Remove special characters, spaces, or symbols from the file name.
  • Use a simple name like background-video.mp4 before uploading.

4. Use a Different Browser

  • Try uploading the video in Google Chrome or Firefox.
  • Clear your browser cache and disable extensions that might interfere with uploads.

5. Check Internet Connection

  • A slow or unstable connection can cause the upload to fail.
  • Try using a wired connection or a different network.

6. Upload in Incognito Mode

  • Open a new Incognito/Private Browsing window and log in to Webflow.
  • Some browser extensions can block uploads, so this helps narrow down the issue.

7. Convert to a Lower Resolution

  • Webflow automatically optimizes videos, but high-resolution uploads (e.g., 4K) can still cause issues.
  • Reduce resolution to 1080p or 720p before uploading.

8. Try a Different Video

  • Test with a shorter, compressed MP4 file to see if Webflow accepts it.
  • If a small file works, the original video may need further compression.

9. Contact Webflow Support

  • If none of the above steps work, reach out to Webflow Support with details about your issue.
  • Include your browser, file size, format, and error message for a faster resolution.

Summary

Ensure your video is MP4 format, under 30MB, and has a simple filename. If uploads still fail, try a different browser, compress the file, or reduce its resolution. If the issue persists, contact Webflow Support.
