Advanced Settings
The following are Advanced Settings that are only visible when the Show Advanced Settings tick box is
enabled.
IMPORTANT: These settings should not be changed unless instructed to do so by vMix Support.
Many of these settings can potentially have an adverse effect on performance and quality on most
systems.
Performance
Output Format
Renders to recordings, vMix Virtual Capture and External Output in the specified format if supported by the
graphics hardware.
This should be left at the default of UYVY in most cases.
Video Renderer
Some codecs such as H264 perform better under the new EVR renderer which can be selected here.
For reliability the VMR9 renderer should be selected if you are unsure.
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.
Application Priority
If you have other programs running alongside vMix, you can set a higher priority here to prevent dropped
frames.
Automatically convert 16-235 to 0-255 for YUV inputs
Tick this box if the black level on inputs such as videos and cameras displays as dark grey.
This setting is automatically handled and detected by vMix internally and should not be changed under most
