In addition, if members are not open for free, there will be advertisements that only support 720p image quality at most (and will last for a long time); After opening the membership, there is no advertisement, and the highest support is 4KHDR image quality (I am not sure whether there is a high frame rate of 50/60fps). Fortunately, this member only needs 9 yuan in the first month, and the multi-terminal and multi-device are universal. However, the final of this World Cup will be held in 12. 18. In other words, if the first month's discount is opened and cancelled before next month, the whole World Cup can be covered. I hope my answer can help you.
