That strangeloop site seems to be the work of experienced 3d visual effect artists. Not anything you could do in ae, or for less than $10k. If its for your sister then just use their stuff.
He meant globally, like composition transport controls. Unfortunately global parameters seems to be the one thing resolume lacks, except for opacity scale and rotation.
Im not sure what the OP was talking about since theres no way to load decks from other comps or to copy decks in resolume, but apparently they were opening the comps in a text editor and copying decks and changing their id's that way.
Yes, this occurs whenver you point a camera at its own capture feed. Ideally you would want a dedicated monitor for this feed, otherwise if you use a projector screen as the feed then you may have to cover alot more distance when moving the camera around. Alot of what you see is usually the monitor ...
Well its a start, but it doesnt offer any control over the duration of the transition, and is limited to blend modes. There also doesnt appear to be any sort of global override, which can prove very cumbersome to change during a live performance.
