Hi ! I read VariableFramerate at Avisynth wiki page but I can't still know well

AVS file I use to make VFR mp4
DirectShowSource("e:\leesooyoung\also i love you.wmv" , fps=29.970)
tdecimate(mode=3,hybrid=2,vfrDec=1,mkvOut="example_timecode.txt")

I found that timecode will change and depend on value of fps
I open this file into VD, VD will say that there are 17397 frames while AviCodec says that number of frames of my WMV file is 7459 . I dont' know why number of frames increase
I often convert WMV into x264. I found that WMV is a quite good codec . Perhaps because WMV can produce 17397 frames from 7459 frames which is saved in file. :)


If content of AVS file is :
DirectShowSource("e:\leesooyoung\also i love you.wmv")

VD will say that there are 17397 frames
If AVS file is
DirectShowSource("e:\leesooyoung\also i love you.wmv" , fps=29.970)
There are also 17397 frames. I also found that DirectShowSource maybe like this fps very much :D
I also have another WMV file. If I set fps=15, result still is good, video is still smooth


I'm said that making VFR is better because there are less frame need to be encoded. But If I set fps to frame = 7459 , video isnot often similar to video which is opend by MPC normaly
