Hi all,
I am combining various effects, and I noticed that when I fade in a video
using the [in]fade=t=in:st=2:n=24[out] syntax, and I fade in text using
alpha='if(lt(t,2),0,if(lt(t,3),t-2,1))', that they both fade in roughly at
the same time, but both are not linear. I'm guessing the fade=in uses a
sine wave or something to fade in the video, while clearly the text fade
is based on a linear fading of the alpha channel. Am I correct that the
video fade in is a sinusoidal fade? Does anyone know offhand how I could
get the text fade to match the video one?
Fade is always linear in this filter.
Good to know, obviously I have something else wrong then. Thanks!
Josh
