Dear sir,

I tested version Vmix 14 with capture card Videum Quattro Xpress - Winnov and is a problem, the image is the vertical black stripes on the screen and deinterlace enabled on each camera.

Vmix version 15 is not able deinterlace each input camera. The image is very bad without deinterlace.

YOU CAN DO THIS Vmix compatible with capture cards?

Best regards

Marius.

When adding the Camera input, make sure an interlaced frame rate is selected such as 50i or 59.94i
and then check the Interlaced checkbox. This will make sure the camera is deinterlaced.

Are you referring to the white lines in the video?
These are analog interference and can be caused by the cables, the camera or the card, but are not something vMix can fix.

Could you provide a screenshot of the Add Input -> Camera window in vMix
and also a screenshot of the camera within vMix showing the lines.

It may be that the graphics card in the computer is causing interference as vMix relies heavily on the graphics card.

Thanks, the picture in that screenshot looks ok.
What are the system specs of the computer such as CPU, graphics card etc?

It looks like the interference is caused by the card when adding multiple inputs.
I would suggest reporting this issue to Winnov as it does not appear to be related to vMix.

Hi Marius,

The inputs are already being deinterlaced, this is the same as vMix 14 but has been labelled differently.
(50i instead of deinterlace box)
The interference seen on the video is not interlacing.

Regards,

Martin
