我知道这些函数的意思
不过就是不明白
为什么你要把一个动画分成三段
然后每段又除以不同的数字
所以我发了这个，几个帖子都看不就行了
This framerate is very irregular, as 119,8 is not a multiple of any regular framerate, divided by 5 it gives 23,96fps and not 23,976
I will then suggest the following to get smooth motion by 23,976fps:
Just open the file in VirtualDub, select direct stream copy, go to framerate, change framerate to 119,88 and decimate by 5
Or if you want 29,97fps, decimate by 4.
when you look to the video, the pattern is something like this :
0 : when Vdub indicate [] in the type of frame
0 D D D D 0 D D D D 0 D D D D 0
at the last "0" frame, the image change, so there is 15 frames which are identical.
in another passage where there is lot of mouvment, the frame change on each "0" frame :/
the new pattern is : 0 D D D 0
try first decimate by 5, if it's not smooth, then try decimate by 4
If you don't decimate the stream you're wasting space because you're encoding a duplicate frame every 5th frame
