[Solved] Video screensaver takes too long to play, 30 seconds of black screen.
It would be helpful if there is something I can do to get the video screensaver to play sooner. The video is 20 MB big and on this Macbook Pro machine, with a 2.4 Ghz Intel Core i7 and 16 GB memory, it takes about 30 seconds of black screen before the video screensaver starts playing. I built it out using only one video to loop "Forever." I used HandBrake to compress the video down to 9.6 MB and it still looks pretty decent but still takes about the same amount of time to start playing. Any tips? Are there settings I should check/uncheck to help out with this?
