[Solved] Screensaver plays smooth on Mac, slow on Windows PC.
Hey there iScreensaver,
Here I am with a new question this time around. Built out a screensaver this time using an .mp4 video like the last one I did that you helped troubleshoot with me here. The video and resulting screensaver file is much smaller this time. Final installer is about 14.1 MB instead of 48.4 MB like the first one. Despite the 48.4 MB one playing smoothly on the PC, the 14.1 MB one is considerably slower and playback is choppy as if a lot of frames are missing. I would think that if the same PC could handle the 48.4 MB screensaver, it could handle the 14.1 MB like a piece of cake. What do you think is tripping it up this time?
QuickTime and iScreensaver software is the latest and I built out the animation using After Effects, same as last time.
