quality property

Video quality, this value is valid when the video rate control mode parameter is set to constant quality. The valid value ranges from 0 to 51. The default value is 23. If you want better video quality, lower the quality value based on 23 to test the adjustment. If you want a smaller file size, test the adjustment by increasing the high quality value at the base of 23. Take the file size under the value x as an example. The file size under the value x + 6 is half the size of the file size under the value x, and the file size under the value x-6 is twice the size of the file size under the value x. On web platforms, this property does not take effect.
