That's a still from a video I'm working on. What's up with all those weird lines? Everything should be solid... and it hasn't always been like that. I opened up my project one day and it was just like that out of nowhere. And it's not every frame, either, it's certain frames only, but still noticeable when playing in full speed.
Also, when I try to use the "Build Dynamic RAM preview" feature, I can only do so for about 4 or 5 seconds of footage. Before, I'd be able to do it for 30 or even more seconds at a time. This is really annoying, and I haven't changed any preferences or options to cause this.
Also, I know that I can just go to Preferences and raise the "Dynamic RAM preview max," but even increasing that to the maximum amount possible still doesn't allow me to to do it as long as I used to be able to.
