If you've uploaded a video to your course curriculum, but have encountered delays or issues in the processing stage, then please refer to the troubleshooting steps below. These should help clear up the problem so you can resume building or editing your course.
Troubleshoot video processing
When the upload bar has filled completely, the file will begin processing and it should finish processing on its own. If the file is still processing after 5 hours, however, please delete the lecture and start again.
Error message
If you see the error message There is an issue with your file preventing successful processing, then please try the following steps:
- Make sure that the file name does not contain any special characters or symbols. Try removing spaces and underscores
- Change the video format. The preferred format is .MP4 codec H.264
- Reduce the size of the file. Uploads should not be larger than 4 GB.
- Reduce the resolution of the file. Videos up to 1080p are preferred.
- If you're uploading a PDF, make sure that the document is not password protected.
- Check that you can open and view your file on your computer and it is the correct file.

You notice that the resolution of the video you recently uploaded is lower than the resolution of the original video file
When a video is initially uploaded to a course, a lower resolution is made available in the course player so that learners can view the video as quickly as possible. Higher resolutions, such as 1080p or 4K, will generally become available within 2 hours. The same applies if you are previewing the new video in the course player after uploading it to the course. If you are still unable to view the higher resolutions in the course player after 6 hours, please contact Udemy Business Support.
