Hi,
I try asking again, just in case my previous message has not been read because it was too long.
Is there a way to have alpha working with [pix_film] on Mac?
That is, read RGBA video files with some transparency (i.e. nontrivial alpha channel) on Mac without ignoring the alpha channel?
This works on Windows:
[gemhead] | [alpha] | [pix_film] | [pix_texture] | [rectangle]
However, on Mac the whole pix is 100% opaque no matter what's in the alpha channel of the video file...
thanks m.
For a reason I can't explain I usually use
pix_film | alpha | pix_alpha

the order of appearance of [alpha] is not relevant (as long as it happens before the Geo): it just enables alpha blending.
[pix_alpha] will calculate the alpha-mask on the fly, which i think is not what matteo wants (he wants to use pre-rendered alpha-masks; see chris' answer on this)

Hi, What values do you use for high and low threshold colors to have the ALPHA channel of the _original_ image be preserved (or recreated) in the output image??????
Send a 'colorspace RGBA' message to pix_film before loading the file.
Only a few codecs have an alpha like Animation (millions+), None and PNG.

Thank you!
Will it work even if opening the files with [open myfile.mov RGBA( is not working?

Yeah, I'm using Animation, and it works fine in Windows (also, on Mac I open the file in AfterEffects and can see the transparency).
thanks m.
