Also, the quality of the video will depend on the speed of your Internet.
The video player is configured in such a way that the priority is to upload the video to the lesson page, and then the video quality.
That is, if you do not see a clear picture on the video player, please wait a few seconds and let the player adjust to the speed of your Internet connection.
If you have a stable internet connection with good speed, you will see a good video picture from the first seconds.
