> Every practical use of that 50 gb copy of Home Alone would have you transcoding it. Most clients would choke on that bit rate.

What clients are you using? I use the highest bitrate HDR videos possible. I very rarely have to transcode. 4k TVs are cheap as are 4k streaming devices.

The main case for transcoding is playing a video in a browser that doesn't support the original codec. Everything can handle high bitrate streams now. The one other rare exception is video that's over 100Mbit/s. I've encountered a few that are that high and some streaming boxes can only handle 100Mb.
