I am using 4 video tracks with the video on the bottom level and photo overlays on the other three (VMS Platiminum 6.0). I had used a composite level envelope on the top level, but then eliminated the need for it and turned it off. My renderings prior to turning it off were fine. After turning it off, the video now bleeds through the video if there are no other events on the two tracks in-between. If I put the envelope back the bleed through still happens. I have moved these photos to lower tracks to eliminate this problem this time, but now must do another 7 hour rendering (I use Best render because I found it minimizes interlacing on photo zooms). Is there any way to prevent the bleed through (I did check to make sure the photo fade bars were all the way up).
