SSA: Make part of subtitle line completely transparent?

[Tri]

Hi!

How do I make a part of a single line in an Substation Alpha Script completely transparent? Not the whole line, but just some words...

i think by enclosing that part into \alpha codes like this

first part {\alpha&H00&}invisible{\alpha&HFF&}second visible part

i'm not sure tho, since i never tried it explicitly and this whole thing with "specific color/alpha channels" (\1c,\1a,..) is not clear to me in the specs :(

[edit] that's ASS tho, not SSA (afaik SSA has no transparency at all)

SSA has transparency effects, but it's limited only in Style definition and supported only in Version 5 Prerelease 1, not as override in a line with the {\alpha} command (that is ASS as you said)

I got it working (ASS was fine, too).
{\1a&HFFF&} makes the primary colour invisible, 1 substituted by 2/3/4 the other colours.

ah the numbers are for primary/secondary/.. - that .doc floating around calls them "color channels" ZOGM so confusing ..channels are so obviously R,G,B,A,Y,Cr etc for me :p i really did not think about that possibility..
