Comment (by cehoyos):

 Replying to [ticket:7055 navilor]:
 > I have some MPEG-PS content that is behind NTSC hard telecine. As such I
 am using both yadif and decimate to remove that.
 Why? Do you believe it is a good idea to use a de-interlacer for the
 inverse telecine process? (It usually is not a good idea because it
 permanently damages your video while the inverse telecine process should
 be lossless.)
 You may or may not have found a bug but using a command line that never
 makes sense makes me wonder if there really is an issue.

 > And please simplify your command line: The -r option is wrong, others
 should be unneeded.
 Sorry for being unclear: If `-r` is needed (it should not but this likely
 an effect of using `decimate` incorrectly), the correct syntax would be
 `-r 24000/1001`.
 Please try to simplify the command line and please provide command line
 including complete, uncut console output to make this a valid ticket.
