yes that works but what about motion blurred stills?
Usually I don't use something like frame 1,2,3 but frame 10, 20, 30 and so on. This way there is enough time to MBlur stuff like cars (also keyed for a distinct frame; the car would only drive from frame 15 to 25 from/to a location suitable for frame 20 when rendering that frame to get the motion blur).
But atm in this case you also have to key the cam at least at frame 19 and 21 to stay where it is because when using a physical cam you cannot switch off camera motion blur seperately from object motion blur like Corona Render setup provides. I made a
request exactly for this reason to have the option to switch both independently in corona CameraMod, I hope CoronaCamera will have it finally.
All you need to do then is to render a range from e.g. 10 to 110 with every 10th frame activated in render setup and you can render out or submit all shot´s at once - only the resolution change is missing. And I still presume this is very hard to implement even with a dedicated CoronaCamera because so many other things depend on it, let's see :)
Good Luck
