[FFmpeg-user] telecine pattern 5555

Apparently 'ffmpeg -i IN -f ????? OUT' is not correct. Apparently '-f' is a switch for forcing 
container formats (usually not needed as file extensions are normally used to set this).

Here's a filter description I found in '5.4 Main options' of the documentation:

-filter[:stream_specifier] filtergraph (output,per-stream)

Regarding 'telecine pattern 5555', is 'telecine' a filtergraph?

Regarding '[:stream_specifier]', do the brackets, [], denote an optional argument (as is usual in 
documentation) or are the brackets literal? (Note that I've seen literal brackets in filter_complex 
command lines.)

Why are there no clarifying examples in the documentation?

Why is ffmpeg making things so difficult to use it?


I want to try the telecine filter to convert p24 by applying a 5555 pattern.

telecine pattern 5555

I hope the result is 60 FPS but I suppose there'll be some discovery at the end that I'll have to 
figure out how to fix. For example, I don't know whether the result will be progressive or interlaced.

How do I form a command line?

ffmpeg -i IN -f ????? OUT
