Sherlock would enjoy this one.
The Crop Node helps with the bounding box and is a pretty quick re-format. It helps when your animation takes up a little bit of space but the bounding box is huge. Not only can you control the x- and y-axis, you can also control the width and height of the crop boxes. Clicking on the little 'reformat' box zooms in on the little thing that you've cropped out. I kinda feel like that's too good to be true :3 As for the little intersect thing, the DigiToots guys said that there's basically no need for it. SO WHY HAVE IT? The plot thickens. For no apparent reason.
BOOP || TUTORIAL NUMBER SEVEN: REFORMAT NODE
Okay, so this one is proving to be rather difficult because I keep getting errors on a lot of stuff. The Reformat Node works better at scaling things up to match project settings. If you choose the little box option, then you gain control of the width and height. The fit resize type option will get the shortest side of the image to fit into the bounding box. There will be pixels stretched. There will always be pixels stretched. unless you click on the BlackOutside box. BlackOutside saves the day! And then there's the distort resize type, which will bent and reformat the output format. Yeah, it'll reformat it. Who's shocked? I'm not.
BLOOP || TUTORIAL NUMBER EIGHT: TVISCALE NODE
Some filters have better sharpening capabilities than others, but the image will still look slightly blurred, regardless of what you try to do. Something that sounds like "in painting" is what happens when there is data missing (If you double the size of the pixels, it's filling in four color squares. So that's like 2/3s to 3/4s of the data missing. Yikes.). The TVIScale Node is best for something called pixel doubling, as it doesn't really work on any other scales...
