Video playback is distorted in virtual machine

  • Parallels Desktop 4 for Mac


After upgrade to Snow Leopard when you play video files in virtual machine they may be pixelated, distorted, flickering or just stop at first frame. Sound plays fine.
The issue is reproduced in windowed and full screen view modes. In Coherence mode video usually plays fine.


The issue will be fixed in the nearest Parallels Desktop update. So far, as a workaround, please disable 3D acceleration for video settings in virtual mahcine configuration.

Configure -> Hardware section -> Video -> uncheck "Enable 3D acceleration" option. 

For Parallels Desktop 4

For Parallels Desktop 5


NOTE: If the video does not play at all or you are getting an error message from your video player please make sure that you have all video codecs installed in Windows:
