Did minimal editing in ColorDirector of my 18 minute Christmas video (auto tone, tinge, white balance, sharpening, noise reduction - not auto). Rendering back in PowerDirector took . . . wait for it . . . 7 hours 54 minutes. I covered these issues in the previous forum (Color Director Rendering Issues) a few years ago. I keep hoping that I'll receive an update that fixes whatever ColorDirector does to the videos. I'm still waiting.
