If your video fails to process, try these solutions: |

|
|
**Common fixes:** |
|
|
1. Convert to MP4 format |
|
|
2. Reduce file size (under 200MB) |
|
|
3. Ensure stable internet connection |
|
|
4. Try a different video file |
|
|
5. Refresh the page and try again |
|
|
|
|
|
**If problems persist:** |
|
|
- Check that your video plays in other players |
|
|
- Ensure the video contains clear, visible actions |
|
|
- Try shorter video clips (under 30 seconds) |
