OK:
1] Put a squarish jpeg with lotsa white background on T1
2] Put another squarish jpeg with lotsa white background on T2
3] Make T2 a Child to T1
4] Apply "Darken" or "Multiply" to T1
5] Apply some Track Motion to T1 to reduce the size of T1 Event.
Result: Black edges to the T1 Event.
Q1: Why?
Q2: What is the cure?
Previously I have done PNGs with a trannie BG. I have never looked into this before. It has been raised by another Vegas colleague, and for the life of me has me beat . . .
TIA
Grazie
