export every size at once
once a shot is approved, a batch node can make every size and cut you need for launch day, from square posts to wide banners.
approve the shot
click the check on the node you're happy with. approved nodes get a mint marble so they're easy to spot.
add a batch node
wire the approved node into a new batch node. pick a size set, like social, display ads or video cuts, or tick the exact sizes you want.
check the crops
rollo reframes for each size instead of just cropping. open any version to nudge the framing by hand if something important sits too close to an edge.
export
select the nodes you want, then press ⇧⌘E. choose png, jpg or mp4, and rollo saves everything into one folder, named by size.
