The Input Previews appear to have an aliasing issue when processing diagonal lines. (see attached screen shot on Cam1 and Cam3)

Computer : ASUS Rog Laptop, i7 CPU, 32Gig RAM, 512 GB M2 Drive, 1TB SSD for Replays, NVidia 980M Video Card

vMix version: 20.0.0.30
Cameras set to : 1080i59.94
vMix Master Frame rate: 59.94i
Output Size : 1920 x 1080

I have tried a multitude of different settings (Master Frame Rate, De-interlacing inputs, etc) but no difference. Perhaps this is just inherent of the processing in a software based switcher. I'm used to hardware switchers..

thanks for any suggestions,
Richard

The input previews are a lower resolution image compared to the program and preview windows. I think that is all you are seeing. The program window looks fine.

You're right, it's more of a resolution than aliasing phenomenon. I'm assuming that this is done deliberately to maintain vMix performance somewhat at the expense of the Multiview quality. I could see where rendering the Input Previews in higher resolution would take more horsepower. I'll get used to it..

Thanks
