If only Youtube had like .. multiple .. videos coming in daily. Then they could encode them simultaneously on a single CPU each. (And serve AVC or fast setting VP9/AV1 until they are done.)
You could do a fast first pass for scenechange detection and vbv estimation and send the chunks along with that info.
