hi list!

i build myself some video-controls in pd,
but i have some trouble with the alpha channel.

1. alpha problem:
the alpha of my videos with [pix_film] has an 1 pixel thick black outline.
and it doesn‘t matter if the file has an premultiplied or straight alpha.

2. alpha problem:
 i use [pix_mask] to mask a video with an image (pure white and pure
but the resulted alpha isn‘t perfect. (a bit transparent where it shouldn‘t
and has an 1 pixel thick black outline.

with [pix_film] i use [alpha] and [colorspace RGBA[.

any hints?
