What the title says. I'm using Vegas Pro 15 on a Windows 10 and messing with Picture in Picture, but I can't seem to get it to work. I have two video tracks, with the inset clip on the top track, "1", and the main foreground clip in track "2". As soon as I add the PIP Fx to the clip in track one it adjusts to the correct PIP setting, but now the foreground has gone black. Oddly enough if I crop the PIP clip down inside it's window I can see the foreground image outside the boundaries. What is going on here? Everything I find says it should be as simple as adding the effect in, but I just can't seem to get it to work! I've also tried adding the Fx to the entire track instead of just the event, and I get the same results.
