I reckon that, except for a few filters, the important metric is PTS, not
the frame #s assigned at a
filter's input node nor its wall-clock arrival time at a filter's input
node. For example,
'interleave' performs frame interleaves based on the PTSs of incoming
frames -- at least, that's
what I think.

Am I correct?

If so, wouldn't it be helpful if filter documentation included how it
generates PTSs?


PTS are not generated.

ffmpeg -i SOURCE -vf telecine TARGET

What are the PTSs of the first 5 frames at the output of the filter?
