Instructors: How to Troubleshoot Video Uploading Issues
Read articleThis article outlines troubleshooting steps instructors can take if they’re encountering issues uploading videos to their courses.
For example, if it’s taking an extremely long time to upload a video to your course, or you’re encountering an error message while attempting to do so.
Review troubleshooting steps for the video processing stage: the processing stage occurs after videos have been uploaded to your course.
How to troubleshoot video uploading issues
Check your internet connection: most uploading issues are caused by a poor internet connection. If you experience issues while the video is being uploaded it could be due to the following:
-
A slow internet connection speed. Try uploading the videos when your internet connection is faster. Or, try uploading the video from a different internet connection.
-
The data limit for your internet provider has been reached. Try uploading the video from a different internet connection.
-
You are connected to the internet through a VPN and your connection provider has blocked uploads. Try uploading the video from a different internet connection.
Ensure the video file name doesn’t contain special characters or symbols: make sure that the file name for the video does not contain any special characters or symbols. Remove any spaces or underscores from the file name. Once you’ve edited the video’s file name, try uploading the video again.
Make sure the video meets the requirements: in order for the video to upload the video must have a resolution of at least 720p and the file must be less than 4.0 GB in size.
You’re encountering error messages: if you are receiving one of the following messages, there may be an issue with the Udemy platform.
-
“System couldn’t initiate their upload”
-
“Signature is not correct”
-
“Problem initiating upload request”
-
"Invalid according to Policy: Policy expired"
These issues can often be resolved by deleting the lecture and uploading the file again from a different browser like Google Chrome. You can also try uploading your file using the Bulk File Uploader.
If you are still having trouble, please contact our support team and include the following information:
-
The lecture file
-
The operating system you're using
-
Your internet connection speed

Instructors: Troubleshooting Video Processing Issues
Read articleThis article includes troubleshooting steps instructors can follow after they have uploaded a video to their course, but have encountered delays or issues in the processing stage.
Learn more about troubleshooting steps for video uploading issues.
The troubleshooting steps below should help resolve the video processing issue, so you can resume building or editing your course.
Troubleshooting video processing problems
After the video has been uploaded to your course, and the upload bar has filled completely, the file will begin processing and it should finish processing on its own.
The video file is taking hours to finish processing: if the file is still processing after 5 hours, however, please delete the lecture and start again.
You encounter an error message: if an error message informs you there’s an issue with the file that’s preventing it from processing correctly, then please perform the recommended action. Here are some of the troubleshooting steps you may need to take:
- Make sure that the video 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 (with an AAC or MP3 audio codec).
- Reduce the size of the video file. Uploads should not be larger than 4 GB.
- Reduce the resolution of the file. Videos up to 1080p are preferred.
We also recommend checking that you can open and view your file on your computer and it is the correct file.

Supported File Types
Read articleThe Udemy platform supports several different types of files for lectures, and many types of files for additional resources, if you wish to include more content that students can download.
Supported Files for Lectures
Udemy courses can include article, video and mashup lectures, and these can be created using several different types of files.
- Article lectures can be created using the platform’s built in, text editor, and .JPG, .PNG .BMP and .GIF files can be inserted into the article using the add image option. Please note that the image files must be smaller than 1 MB.
- Video lectures can be built by uploading .AVI, .MGP, .MPEG, .FLV, .M2V, .M4V, .MP4, .WMV, .OGV, .WEBM and .MOV files. We recommend using MP4 files if possible, however, as we have found the uploading process works best with these.
- Mashup lectures combine videos and slides to create a compelling lecture. The video files must be in a .MP4 or .MOV format. The slides, on the other hand, must be in .PDF format. So, if you’re using software like Powerpoint or Keynote to create the slides, you will need to export them as PDFs.
Supported Files for Additional Resources
Adding additional resources can be a great way to enhance the lecture, and provide students with a more comprehensive learning experience. Please note: these resources must be available for free, related to the lecture topic, and not promotional in any manner.
The additional resources section features nearly any kind of file type, including .JPG, .PDF, .ZIP, .XLS, .MOV, .MP3, .PPT, and .DOC, among others.
Source code like .HTML, .JS, etc., however, cannot be uploaded directly, but these files can be uploaded in a .ZIP file.Source Code for Development Courses
Only Python and Ruby files can be uploaded at this time.
Uploading the Files
Files can be uploaded to the lecture by using the browser uploader, or by adding them from your library using the bulk file uploader.
Please note: .MP3 files for additional resources must be uploaded using the browser uploader. -
Troubleshooting Closed Caption Upload Errors
Read articleThis article outlines the error notifications instructors might encounter while attempting to add closed captions to your course lectures, and how can you resolve the issue.
For steps on how to add closed captions to your course videos, please click here.
Incorrectly Formatted Timing Information
If your caption entry includes timing information the system cannot read, then you will see an error notification reporting one or more of the entries has incorrectly formatted timing info.
In order for your .vtt closed caption entry to be accepted, it must be formatted with one of the timing formations below:
00:00:00 (HH:MM:SS)
00:00 (MM:SS)
00 (SS)
00:00:00.000 (HH:MM:SS.mmm)
00:00.000 (MM:SS.mmm)
00.000 (SS.mmm)
Please note: ‘m’ stands for microseconds
In addition, caption entries must have a start time that is earlier than the end time that’s been entered, in order for it to upload successfully. Accordingly, the caption entries also require a start time that is later than the previous entry’s start time.
If you receive an error sign indicating this is not the case, then you will need to edit the entry’s times.
Missing Timing Information
If the .vtt file has a correct header, but doesn’t have any timing information, or it can’t be recognised due to incorrect formatting, you will see an error sign reporting that one or more of the caption entries has text but no times.
The correct formatting for the timing information looks like “00:03:00.000 --> 00:05:00.00”. Please note that the separating arrow must have one or two space or tab characters on each side.
Missing WEBVTT Header
If the caption entry is missing the WEBVTT header, which is required for valid vtt files, you will see an error warning indicating this. Please add WEBVTT to the first line of the file in order to resolve the issue, as shown below:
Missing Track Text
If one of the caption entries has timing information but no text, you will be notified via an error sign. Each caption entry should have a start time, end time and some text in the following format:
No Caption Entries
Each caption entry should have a start time, end time and some text, and each caption entry must be separated from another with at least two line breaks. If the entry doesn’t, an error sign will appear indicating that there are no recognisable caption entries in the file.
Caption entries should be created with the following format:

Upload a Course Image
Read articleA course image gives students a snapshot of your course content, and can be a great way to grab a student's attention.

Textual information such as the name of the course is not permitted within the course image. For more information on the quality guidelines for course images, please click here.
