Premultiplied Alpha: Using zero Alpha to implement additive color
hi,
is possible tell ppro not ignore pixels having color values , 0 alpha value when in premultiplied alpha mode?
premultiplied alpha in these equations
out_alpha = (1 - new_alpha) * old_alpha + new_alpha
out_color = (1 - new_alpha) * old_color + new_color
should result in additive blending if new_alpha zero.
but in ppro nothing displayed.
sdkfileinfo8->vidinfo.alphatype set alphablackmatte. setting wrong mode?
best regards
