In the example composition ShowLiveAudioWaveform the waveforms quickly go out of focus. Also there is a composition with 5x5 ovals or spheres with the word "Disco" in the title that has blurry, out of focus ovals.
Yet other example comps are sharp like ShowSpheresWithLights.
How do we control DOF in the Renderer?
(Also a search of "Disco" in the node library and my mac failed to find the composition, probably need a way to search through example comp names if they are to be relied on as a node use reference manual of sorts.)
