Alpha Channel Support for NDI Sources

vMix automatically supports alpha channel when it is detected on an NDI source

Alpha Channel Support for NDI Output

When using the Output and External 2 options with NDI, these will by default send standard "YUV" video without alpha channel.

To enable Alpha Channel on output, select ARGB32 as the Output Format under Settings - Performance

Note: certain features in vMix such as Recording may not work as expected when ARGB32 is enabled
