Figure 8.21
shows the pipes colored red and green. This mirrors the
colors of the views in the Views tab. I colored the pipes by selecting
the Use colours in UI check box at the bottom of the Views tab.
6. Make sure you are viewing JoinViews1 in the Viewer and use the Left and Right
buttons to switch between the views.
You can see the two Read nodes' output in the Left and Right views now instead
of through separate Viewer inputs. This is the beginning to working with views.
Later in this chapter you will do more.
For now, there is just one more thing to set up so that you can work quickly with
such large-scale images.
Using proxies
Working in 2K (over 2000 pixels wide, that is) can become very slow, very quickly. Be-
cause compositing software always calculates each and every pixel, giving it more pixels
toworkwithdramatically increasesprocessingtimes,bothforinteractivity andrendering.
For example, a PAL image of 720×576 has 414,720 pixels, which is seven times fewer
than a normal 2K frame of 2048×1556 with 3,186,688 pixels! So it's that much slower to
work with.
Nuke has a few ways to make working with hi-res images faster. First, there is the Viewer
the display resolution. Input images are scaled down by the selected factor, then scaled
up in the Viewer by the same factor. This creates a speedier workflow with just a quality
difference in the Viewer.
