[Solved] Screensaver has a hiccup
I'm using the free version of the program and have created a very basic screensaver out of an HD video. I'm using a mac. When I install the screen saver and use it, it plays for about 5 seconds then starts over with the watermark in a different spot. Any solutions to this?
Also is there a way to make the file sizes smaller? Mine is currently 114mb and it would be great if I could compress it somehow.
