That's also a great option if you don't need transcoding or tone mapping and can restrict your collection to specific codecs to ensure client compatibility. For my setup quicksync essentially is a requirement since I want to download certain items in the best quality and have remuxes in 4K HDR 7.1 for my own home theater while being able to transcode those items to multiple friends simultaneously and on the fly without needing to keep a separate 1080p copy.

So far I've seen around 7 simultaneous transcodes on my NUC yet the CPU usage stays below 10% because the quicksync is handling all the transcoding while sipping power (another big benefit to using QS over CPU or GPU transcoding).
