[FFmpeg-user] sc_threshold value

[jacky]

Hi every body

May be it is a stupid question but I have'nt found answer
sc_treshold value is related to scene detection
leftover it is enabled and sc_threshold 1 disabled
is there others options (0,2,3....)
how much the option 1 degrades quality on amphi courses where there
are slow changes (except during zoom )
do you know some links to get some insights ?
best regards

jacky
