The video source file is 1080p, more than 3000 kbps video, about four minutes in length.
On the PC side, I compressed it to 720p, 1000kbps, and the size is about 30M.
But if it is to be placed on the mobile terminal, I feel that the size is still a bit large, but I can’t decide how to compress it. Such as width, height, bit rate, etc. Too much compression is not good, but too much definition is a waste.
Are there any seniors who have experience in this area? How to choose a parameter that is suitable for most mobile devices?
