I've had zero issues with VMS since version 12 to 14. But with the same video equipment, now I'm having video rendering issues. First black screen spots in rendered video with just audio. Which I seen it was suggested to set "Dynamic RAM preview max" to "0" (GPU accelerator "off"). Which I did, but now I'm seeing layer drops in the rendered video where the video layer under appears instead of the layer above it. Plus when I drag marker across timeline it leaves a trail of ghost marker points. Everything is the same (same computer & equipment) from Movie Studio Platinum 14 and I had no problems. Wish I could import file back to 14 just to render, but I can't. I have people waiting for their stuff and I can't deliver because of these issues. Please help.
