a quick question to help me clear this up - does the video master track ( ctrl+shift+b) really affect preview only? If so, is there no "real" video master bus that could have final FX on it that would apply to the actual render?
Thank you all for your replies.
I initially understood / thought that it's a real master bus, but what got me confused was the plugin called SEMW extensions, which has a context box on its switch to set the preview output to PC RGB saying: "this will not affect the final render".
Maybe it disables itself on rendering, not sure.
Anyway, thanks for clearing that up for me.
Yes, Preview Levels actively disables its output effect during rendering. "This will not affect the final render" only refers to this particular effect instance. Effects you add yourself will always act both on the preview and the final render.
