Aescripts – Retend v1.5

You need a precomp three seconds longer, or the whole sequence at double speed. Until now that meant opening every nested comp by hand, dragging out-points one at a time, retiming keyframes property by property — or reaching for Time Remapping and quietly wrecking the frame rate for whoever opens the project next. Retend replaces all of that. Select a precomp layer — or select nothing, to work on the whole open comp — type a target duration or speed, and click. The entire nested tree, however many comps deep, changes together, correctly, in one action.
