What is the antecedent of "this"? We've received no information yet, so how can you refer
to "this"?
Is there not a risk of long-term rounding errors?
Not for CFR I'd imagine. Perhaps that's why some informed folks advise to use
solely CFR.

Disclosure: Everything that follows may be wrong.
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?
Interpolated by very complex formula.

It isn't the distance that's important, it's the direction.
