[Solved] HD video washed out on windows version

edited September 2018 in QuickTime
The clips when I finally download them to a windows machine are too bright. I think I need to make different versions for each platform but I'm asking what's the smallest change I ought to make to keep the quality as high as possible. Gamma, exposure, contrast/brightness?


  • Great question!

    Mac and Windows used to use different Gamma settings:

    Recently, both use the same.

    There can still be differences in Monitor or Projectors, though.'

    Can you say more about your situation?
  • Yes, Using the exact same video clip to produce the "demo" on the website ( windows/mac machine comparison= pretty close. Same test with iscreensaver= windows7 too bright, washed out and jerky.
  • Would you please send us an email at support at providing us a way to download and test the mac and windows versions?
  • Please note that iScreensaver Designer 5 has been released which addresses many of these issues: you can now use standard MPEG4 (M4V, MP4, H.264) video files which may address your issues.

    Please see for a list of new features in version 5.0.
