Hey @Pierre, you didn't mention the file resolution, but if you uploaded videos in 1080p, they'll be displayed in 720p until your course is published and you request our support team to enable adaptive streaming. You can read more about our requirements and recommendations for course videos in our Course Quality Checklist linked here. Also, check out our Video Standards and Choosing a Camera support article. If you think something is not working right, please contact firstname.lastname@example.org and send one of your video files. The team will gladly investigate further.
