Hi @MiranFattah,
Thank you for reporting this problem. The first thing I'd like to suggest is that you make sure the video meets the requirements: in order for the video to upload correctly, it must have a resolution of at least 720p and the file must be less than 4.0 GB in size. You can take a look at the following article: How to Troubleshoot Video Uploading Issues and Video Standards and Choosing a Camera for more details on all the possible reasons why this could be happening.
If the issue persists after following these troubleshooting steps, please reach out to our Instructor Support team, as they will be able to take a closer look into this for you.
Thank you for your patience and collaboration!
