I would like to see a very simple Nuendo Video Satellite. Basically it would be the same as “streamers” but with all the new ADR features it would be far better to have a Steinberg dedicated program.
So the idea is that you have a program that has JUST the video engine, that syncs to Nuendo through either Ethernet or System-Link. The only extra would be that it copies all the markers/video overlays from the main program.
This would allow you to work at lower latencies with higher quality video for minimal extra costs. I think the program could be really simple as most of the code should already be “there”. (video engine and network capabilities)
Hope you take it in consideration 
Cheers
