Hey @FarukCivaner, In order to publish your course, you must have at least 30 minutes of video content in your course. Additionally, Udemy requires that video content is HD quality, with a resolution of at least 720p.
You can read more about our requirements and recommendations for course videos in our Course Quality Checklist linked here.
If you’re filming a video for your course, here you can find several different types of cameras that have been used to record published Udemy courses.
Hope this helps!
