[QUOTE="The3, post: 881346, member: 126914"] Small update: When I bring up the "shift+1" info display, all of the plotted lines are smooth and straight (more or less) for the videos that play back properly. But for the ones that don't, the red line looks like a short period sine wave continuously, and occasionally plummets with a deep valley (along with the green line) when the image freezes for a moment. Also, I did some experimenting in Handbrake to try to identify exactly what resulted in the problematic files. The videos that stutter were transcoded using the "High Profile" preset with all of its settings left alone except for the RF value manually adjusted from 20 to 19. When I transcode the same source files with the "Normal" preset, again making the same adjustment to the quality RF, the videos play smoothly. Ideally, I'd rather not have to steer clear of the high profile settings, as the normal preset produces files that are slightly too low in quality for my taste. [/QUOTE]
