Howdy,
I've done this before successfully but I reckon I'm doing something wrong this time and would appreciate it if someone could point it out for me: I cut-out a section of a photo using my cheesy photo prog (Roxio Photo Suite). I saved as a 32 bit .png and imported it into V4. I place on an upper track and select properties/alpha channel/ pre-multiplied....nothing happens so I check to make sure that track's compositing mode is set to "source alpha", it is but I still have a white square arond my round cut-out. I then click "multiply (mask)" and the white is totally transparent and the round cut-out is translucent. I have a feeling the imported .png is okay but I have something set wrong in V4.
TIA for your help,
Randy
