Christopher Nolan took a playful swipe at streaming while introducing a Los Angeles screening of “Oppenheimer” that was devoted to spotlighting the film’s craft. Crew members reunited for the event Monday evening, billed as “The Story of Our Time: The Making of ‘Oppenheimer.'” The director said a lot of time and energy has gone into assembling the “Oppenheimer” Blu-ray so that it preserves the film’s soundscape, which is one reason moviegoers should buy a physical copy as opposed to waiting for the movie to stream.
“Obviously ‘Oppenheimer’ has been quite a ride for us and now it is time for me to release a home version of the film. I’ve been working very hard on it for months,” Nolan said. “I’m known for my love of theatrical and put my whole life into that, but, the truth is, the way the film goes out at home is equally important.”
“‘The Dark Knight’ was one of the first films where we formatted it specially for Blu-ray release because it was a new form at the time,” he continued. “And in the case of ‘Oppenheimer,’ we put a lot of care and attention into the Blu-ray version… and trying to translate the photography and the sound, putting that into the digital realm with a version you can buy and own at home and put on a shelf so no evil streaming service can come steal it from you.”

DVDs have a maximum Bitrate of 10 Mb/s. This is like 5 Mb/s with H264 or 2.5 Mb/s with H265, since the compression back then was MPEG2. Feel free to look up Bitrates of streaming services. YouTube is at roughly 15x that with 4K videos. 720p uses about the same.
Bitrate per pixel is what we’re talking about. Bitrate alone tells you nothing. If you’re actually receiving a full as-advertised bitrate stream with a well-implemented compression algorithm then obviously if all else is held equal then higher resolution = higher quality. But in reality many streams are overly compressed to save on their bandwidth and server costs, and often due to tech inefficiencies you won’t actually receive the full bit rate, resulting in even more additional compression losses.
Again, a perfectly-implemented, perfectly-transported stream in 720p will always look better than a 480p dvd file. But in reality there are many situations where a stream is imperfectly-implemented and imperfectly-transported, sometimes to the point where visual quality worsens to below what you would get from an upscaled 480p dvd.
But anyway, neither of us are true experts on this topic. If you’re always 100% happy with the quality of the streams you see, then that’s great! But many of us sometimes encounter streams where the compression causes obvious visual degradations to the point of being distracting. Personally i prefer lower resolution with no obvious compression artifacts, rather than higher resolution with obvious color banding and visual noise in motion sequences.
I am not always happy. But I can also see that a DVD has lower quilted than essentially any YouTube video. Of course unless it was uploaded in lower quality to begin with. The source material has to be good enough. There are more than enough 1080p videos that are only 360p. Or 4K that is only 720p. Not due to compression, just from the source material.
