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.
