Does WebRTC / vMixCall support interlaced sources or vMix to vMix interlaced?

Thanks!

I have been bringing interlaced sources into vMix Call without issue. Usually this will be done by capturing a camera into vMix and passing that onto the call. If you are using a webcam, whether through vMix or a browser, they normally bring in the signal as progressive.

AFIK webRTC uses a progressive format. Someone will correct me.....LOL

I appreciate the reply, Ask :)

I guess I should have clarified, that I'm trying to preserve the interlaced source from end to end (input to output). We utilize vMix for broadcast television NTSC. Converted progressive sources still work ok, but when you have a lot of horizontal panning, the blurring really gets distracting. Like you, I figure WebRTC is progressive, but just wanted to make sure. :)

Thank you!

All image sensors are in fact progressive scanning devices. Interlacing is added electronically later in the process.

Set the correct frame rate (59.94) and you should be able to derive interlaced output without issue.
