Agree with getting rid off quartz, nobody doubts is past. And still thinking we will miss it for some time.
I undestand the power of shaders, not a versed guy on that, but I know patricio and even I'd made some plugins through shadermaker.
Fusion is great piece of software, I'd made a lot of compositing work on it, and blackmagic adquisition opened up a great community around it (we started to share workarounds and lua scripts with nuke people since then, not a minor thing).
From my personal view, just thinking that qz gived to me the ability to make an animated lowerthird, loading dinamic content and controll it from resolume, in deathline and without the need of write a single line of code!
I will miss that simplicity.
Anyway, when a standard procedure breaks up, we can see emerging a lot of exciting new ways.
About Notch, not for me but, do you noticed that DXV is a supported format?
