Performance

Preview Skip

Tick this option to skip every x frames when rendering the preview.

For example if the output is rendering at 30fps and the Preview Skip is set to one, Preview windows will render at 15fps.

This is useful to improve performance on older Graphics Cards.

Synchronise Output with Refresh Rate

Tick this option to eliminate tearing on the Fullscreen Output Window.

(Tearing looks like flickering lines in the middle of the video)

This option is not required when using vMix under Windows Vista or Windows 7 in Aero Glass mode.

Render Effects on Input Windows

Render effects such as Deinterlacing and Colour Correction on the Input Windows.

By default effects are only rendered on the Preview and Output windows.

Application Priority

If you have other programs running alongside vMix, you can set a higher priority here to prevent dropped frames.
