Is the writer paid by the word ?!

"and Google seems aware of the responsibility it shoulders running one of the best entertainment apps out there. "

What? Get to the point. Google seems aware that it runs YouTube. Yes I'm sure they are.

Am I seeing the past in a nostalgic light or were DVD 480p considerably better than YouTube 480p? I feel like streaming services compress their streams so hard that the resolution indicators become meaningless.

I watch 4320p (8K) streams when possible because it noticeably improves the quality on my 4K screens — and this is with my worsening eyesight!

That shouldn’t be noticeable if the 4K stream was encoded properly.

It's interesting to see how tiny Netflix mobile download files are.

200MB - 300MB for full-length movies, ~150MB for series episodes. This is on "Standard quality", but still.

After some quick Googling (grain of salt) I see that a standard DVD of 4.7GB tends go have (usual encoding) up to 135 min of 480p video. That's a big difference! Even when considering that modern encoding might be more efficient. It is lossy compression, and the lossyness seems to be cranked way up.

I mean, yeah. It’s how most content writers are paid. And it’s also how the OpenAI API they use is paid (by the token).

DVD's definitely didn't use up the entire 4.7GB. A movie was anything from 700MB to 1GB

I believe this is to some degree due to chroma key subsampling, where in a 4k stream you will only have 1080p worth of light intensity encoded (cluster of 4px). So if you play an 8k stream and downscale to 4k you actually have full chroma (1:1).

There could of course be other factors involved as well but this is definitely a pretty big contributor.

In days of yore before upscaling was computationally practical a better standard was PAL region DVD's that were encoded from master (be that hires digital tape or direct from film).

    In PAL regions, the PAL signal uses 625 signal lines, of which 576 (known as 576i signal) appear as visible lines on the television set, whereas NTSC formatted signal uses 525 lines, of which 480 appear visibly (480i).

    In PAL video, every second line has the phase of the color signal reversed, which leads to the signals flattening out the frequency between the lines.

    Effectively what this means is that damage to the signal appears as errors in saturation (level of color) rather than hue (shade of color) as it would appear in NTSC video, leading to a higher-fidelity picture of the original studio version.

I think you're confusing them with MPEG-4 rips that are burned on DVD-R.
