This is an old problem of sorting. The easiest way is to modify the serial number at the end of the figure. If there are dozens of pictures (the last two digits), then change the number from 1 to 9 to 0 1, 02...09, and then the order will be fine. If there are too many pictures, there are hundreds. Then you need to change 1 to 99 and change it to 00 1, 002...099, and the order will be normal. And so on. This is because the sorting of computers and the like is based on valid records. If the number comes first, it should be 1-9, and then 10- 19. But if the number is at the end, because there are other words before the number, then the computer will sort it according to what you say. By the way, after saving as a picture, if the order is correct, select all the pictures, right-click to rename them and change them at will. After modification, the pictures behind will be numbered automatically. Please put them in mp4 to see if the order is correct. I haven't tried.
