Being a lazy human being, I would love it if I could get clean transparencies within PI without having to use other programs to fix. However, I have a nagging problem with jaggies at the edges of most of my transparencies. I have tried many remedies- changing transparency colors; using source images with clearly defined boundaries; even creating color swatches within images to sample for the color options within the transparency.
Can you believe it, I've even used emitters to blur the edges of images as a last ditch effort. So much for saving work...
It seems like there is either always a bit of color left over or I start to subtract from the non-transparent image.
Do I just need to bite the bullet and use alpha channels only? Create the video in PI and take out the background elsewhere? Am I just bumping into a limitation within PI?
