Recently, a company i work with started using Vmix as a restream computer for its video games WebTV.
Lot of people are streaming on it at different time of the day and they push their personnal stream on a RTMP which is then captured by the Vmix system,to be streamed on the definitive Twitch channel.

I was surprised to see 2 things :
- RTMP input in Vmix are only 30 FPS
- there is no filtering for upscale/downscale.

Problem is : The Vmix system is streaming at 1080p60 (it's gaming content, people like it smooth), but the RTMP just bottleneck the incoming streams framerate to 30. Also, some streamers are still streaming in 720p mostly because of limited bandwidth and also because hardware encoding is not as good as software one, so they don't use it for 1080p. I discovered also that RTMP capture doesn't have any filter option like Bilinear, bicubis or even Lanczos, which would help a lot.

So, question time:
Would it be possible to upgrade the RTMP input in Vmix so you so the framerate can go above 60 and add some filtering for upscaling content please ?

Salut !

Did you try the VLC input type for RTMP instead of the genuine RTMP input?

Bien à toi
