Before undertaking this project I want to try and get off to the right start instead of unnecessarily experimenting on my own. ]]> http://iscreensaver.com/forum/discussion/104/video-screensaver-exits-immediately-in-os-x-10.6-or-10.7 Thu, 12 Jan 2012 11:42:22 -0500 iScreensaver4 104@/forum/discussions
There is a workaround: re-export your video file in another codec. If it is H.264 then re-exporting as H.264 again will usually fix the issue. You can also try other codecs such as PhotoJPEG (large file size, but very fast and low CPU usage).

Purchased iScreensaver Pro a couple of days ago as my client required a short 30sec movie to be turned into a screen saver for both their mac and PCs.

However their IT dept has rejected the screen saver on the grounds that it's too resource heavy.

The screen saver I originally created was at 1600 x 1000 pixels @ 24fps.

Deciding that it was possibly too large I've been experimenting and reduced the size to 768 x 480 with the video set to crop. There's a big loss in quality but it would be acceptable.
Unfortunately they have also rejected the lower res version on the same grounds (excessive CPU usage) so have been trying a few things here on my mac.

I've noticed, that running a screensaver built with iScreensaver, containing nothing more than a 6mb h.264 quicktime movie uses upto (and over) 100% CPU. However the same movie running full screen it Quicktime only uses 12 - 15% CPU resource. Running a screensaver containing static images uses significantly less CPU (anywhere between 12 - 30%).

I tried halving the movie resolution again, down to a very pixelated 384 x 240, but it still uses too much CPU.

I've also tried different codes (h.264, jpeg, mpeg-4, etc) but nothing appears to drop the CPU usage.

Hopefully Im missing something obvious - how can I produce a video screensaver that uses significantly less CPU?
Is there an issue that can be fixed somewhere?


My client uses a wide variety of PCs and macs, but my own machines for testing purposes are:
- late 2010 17" Mac book pro, 2.66 GHz intel core i7, 4GB ram, NVIDIA GeForce 330M graphics card with 512mb vram.
- Mac Pro, 2 x 2.66 Dual Core Intel Xeon, 10GB ram, NVIDIA GeForce 7300 GT with 256mb vram.

Mac Book Pro is single screen (no external monitor attached). I've tried the mac pro with both one and two monitors.

Hope someone can help... I'm worried my client might not pay for my work including the cost of iScreensaver pro.


Thanks

For authoring screensavers, QuickTime is still required.]]> http://iscreensaver.com/forum/discussion/35/help-with-using-quicktime-movie-with-sprite-track Mon, 24 May 2010 17:25:31 -0400 Frank 35@/forum/discussions
I am running on a 2007 Intel 17" MacBook Pro. I have Mac OS X 10.6.3, QuickTime 7.6.6, and QuickTime 10.0 installed. The movie element's behavior is set to "Play Forever" in the project and I have turned off Loop and Shuffle in the Global Behaviors. I've verified that the QT movie still plays correctly in the QuickTime 7.6.6 player.

Thank you for your help.]]> http://iscreensaver.com/forum/discussion/22/mac-screensaver-wont-exit-when-mouse-is-moved Thu, 08 Apr 2010 07:56:01 -0400 iScreensaver4 22@/forum/discussions
" Very good software for screensavers! But I have a problem with screensaver with video on my Mac. The video do not stop when I move the mouse, and it is impossible to escape out of the saver, resulting the Mac will freeze.
