alpha masking 3 layers

mark

I found a fix! i set the Video Image Processing preference to Smallest, rather than Default and it works.

If you have images with straight alpha, and you scale them, it messes up the alpha channel. That's the most likely explanation for this.

It would be very important that you use images and video clips that are exactly the same resolution for this process to ensure no scaling occurs. I would encourage you to do that. (Even if the podium doesn't occupy the whole image, just make it the same resolution as the other images.)

That said, there's several issues with handling alpha that we've solved in v2.6... coming any day now.

i'm currently using the new beta. the podium image was cut from the background image, but saved the same size as the background image, so everything was scaling the same way to default values (1280 x 800). Alpha looks to be Premultiplied (check the image above where a patchline hover shows the podium image at default res with premult alpha)

If you want to send me the media I can have a closer look.
