Maybe a silly question, but why would Blu-ray offer better picture quality than iPlayer? I mean, I guess it's the same 4k resolution. Is colour data more compressed / frame rate lower on iPlayer vs Blu ray?
- symfoniq 9y ago4K Blu-Ray can have bit rates in excess of 100 mbps. There's likely a lower bit rate (and far more compression) with most streaming services.
- Crespyl 9y agoIt essentially comes down to bitrate. Even with 1080p, there's still a noticeable bump in quality when you go from the "just enough" streaming bitrate to the "here just have the whole thing" version from a local disk. Both versions still decode to a 1080p (or 4k) frame, but the local version means you don't have to compress it quite as much.
- dawnerd 9y agoStreaming is definitely more compressed, and with movies the audio formats are not always the best since they need compatibility. If you want the best picture quality, get the UHD bluray.
- zeristor 9y agoI’ve watched lots of films on AppleTV using iTunes and Netflix, I’ve not noticed any jarring artefacts. The BBC iPlayer though has banding and images of light glistening on sea waves are horribly blocky. I had assumed this was done to save money. A programme like Blue Planet II being a flag ship show, no doubt showing how good things can get. Sounds like the ideal demo to show off UHD TVs in shops.
