It sounds like Netflix might not be doing the horrible thing YouTube and Twitter do where they treat low-resolution (e.g. standard definition) content as being less deserving of bitrate with only higher resolutions allowed to climb the bitrate ladder? For those sites I have to upscale SD content to HD resolutions when uploading just for it to be allowed a less paltry bitrate. I fear people who grow up in the age of streaming might not realise that DVDs had good video quality because streaming services seem to hate SD content. > As a side note, we do have some additional points, not shown in the plots, that are used in resolution limited scenarios — such as a streaming session limited to 720p or 1080p highest encoding resolution. Such points lie under (or to the right of) the convex hull main ladder curve but allow quality to ramp up in resolution limited scenarios.
