Comment (by Gyan):
IMHO, the docs do give the correct indication
For '''n''' in ''crop'':
`The number of the input frame, starting from 0.`
''number of the'' (singular noun) == serial number -> ordinal.
For ''in'':
`Input frame count.`
count == measure -> cardinal.

Why the filter needs to expose count and not index is better left for the
dev to answer.
