Hi Sam, thanks for your reply, yes the fade line works, however it's not
suitable for what I want to do, I want to fade many snippets of text and
transparent PNGs on the same track, with always the same video
transition filter set to the same duration. Otherwise it's too
complicated to combine them on two tracks and adjust manually the fade
curve for each. I posted the example of fade in text parameter as it's
simpler than transition do explain, but it produces the same "black
flash" bug.

Thank you,
