Well for cin2 we have this project resolution thing, its probably not
easy to plug out of the sourcecode. Thinking about cin3 we have this
'everything is a node in a graph' where nodes inputs and outputs will
have very specific properties like size, color depth, aspect ratio and
so on. Nodes which are incompatible can not be connected together,
point! But cin3 can choose 'conversion-nodes' (scaling, letter|pillar
boxing, framerate, YUV/RGB conversions, etc) and insert them
automatically (or only on demand in HQ/PRO mode). A alpha channel is
something special here since alpha is created by the application (unless
we have some video codec which supports alpha) and more importantly,
alpha is consumed by the aplication too since the renderpipe runs bottom
up, we can pass a 'need for alpha' property up and only when alpha is
needed AND present it will be passed around. Finally encoding will be
done in graph nodes too, that is where you define framerate, resolution
etc. for the output video, there is no global project setting. One could
even have serveral encoder nodes at the end of a renderpipe (or even in
the middle) for example encoding for DV, DVD, SVCD and Youtube in one rush.
