Hi.
When I use filter_complex syntax below, I get an error that cannot proceed.
"-filter_complex
"[1:v]geq=r='r(X,Y)':a='if(between(t,0,9),alpha(X,Y),0)'[alpha];"
then
" Unknown function in 't,0,9),alpha(X,Y),0)'"
Seems geq filter not support generic function parsing.
Please look into it.
Have a
Hi.
There are RGBA support qtrle video clips that have no problem with alpha
support.
I'd like to overlay a video on top of base one, and want to change the
transparency while playing
like
"[1:v]alpha='if(between(t,0,10),(1-(t/10)) *
alpha(X,Y),0)'[v0];[v0]overlay[out]"
What kind of filter sequen
syntax for me?

Thanks Paul. It's verified.
Have a good day.

Hi.
What I know is alpha change for another video clip pon base video like as
"-filter_complex
"[1:v]geq=r='r(X,Y)':a='if(between(t,0,9),alpha(X,Y)*(T/9),0)'[alpha];"
which works very well as time goes by.
But it is not working for a PNG image file as time goes by. It only sets
alpha when the ove
Hi. Paul.
Sorry for the late reply since it verified just now
that working with '-loop 1 -i input_png' right in front filter_complex param
by your reminder. Thanks.
Have a nice rest of the day, Paul.
