 Summary of the bug:

 When the IN video is longer than 35:47, the OUT video switches to fast-
 forward at 35:47.

 SET TELECINE=telecine=pattern=5,split[A][B]
 SET CFRAMES=bitor(eq(mod(n\,9)\,2)\,eq(mod(n\,9)\,7))
 SET PSELECT=[A]select='not(%CFRAMES%)'[C]
 SET CSELECT=[B]select='%CFRAMES%',smartblur[D]
 SET INTERLEAVE=[C][D]interleave
 SET ENCODE=-map 0 -c:v libx264 -crf 20 -an -sn
 ffmpeg -i IN -filter_complex "%TELECINE%,%PSELECT%,%CSELECT%,%INTERLEAVE%"
 %ENCODE% OUT

 How to reproduce:

 Run the script.
