tdecimate(mode=3,hybrid=2,cycleR=1,cycle=5,tcfv1=true,mkvOut="B:\xxx.txt")
压制log提示（按理说通过tdecimate后应该是24000/1001？）
avs [info]: 800x600p 0:0 @ 30000/1001 fps (cfr)
avs [info]: color matrix: undef
mp4 [info]: audio muxing feature is disabled.
timecode [error]: unsupported timecode format
x264 [error]: timecode input failed
mp4 [error]: failed to finish movie.
生成timecode内容（奇怪为何没有生成M-N删帧到23.976fps的tc）
# timecode format v1
Assume 29.971029
# TDecimate v1.0.3 by tritical
