Why does Plex need to transcode this file?

It’s going to a newer Roku device and I have the server set to a 4 Mb limit upload limit. This file is only 104.46 MB MB in size and the show is 23:41 minutes long.

Is Roku that poor at buffering?

What does it say in playback information during playback on why it is transcoding?

Off hand it looks like it is transcoding down to 720p so what is the remote quality set to on the Roku?

It is a Roku Express or Roku Express 4K?

If the HD model, it may not support HEVC video.

According to this thread, only 4K devices support HEVC video.

Sorry for the delay (been out of town).

I think you nailed the reason: Roku model can’t handle HEVC.
