On a 20 Gb MKV file of a Transformers movie, with overal just truly excellent audio and visuals both, an almost flawless rip and nonetheless in between there are frames or shots (seconds) that look like pic. gritty and flawed,
How is this possible? Is there a certain range of color combination or complexity (like the sand blowing by) that makes the encoding of this frame SIgnificantly less adequate than 99.99% of the rest of the movie>?

Download an NFL game and watch how codecs respond to the kickoff.

MKV is a container btw

>implying that's normal grain

...some camwhore-tier lighting there.

properties only showss its ''mkv-file''

yes.. who the hell disagreeds??

digital artifacts due to compression, not grain

That's likely not due to compression, but due to a high ISO used in a fast-moving low-light scene which creates noise at the sensor level, thus already being there in the source.

Grain has its place, either for aesthetic reasons or to hide banding. Sure, if you want to target a small file size you'll try to get rid of any noise, but that's not the case with a 20GB 1080p encode.

That movie was filmed on 35mm

Implying film doesn't have various ISO speeds that get grainier as they get "faster"

Then substitute "sensor" by "film", which in fact tends to have MORE graininess than modern digital cameras.

That said, yeah, the encoder in OP's pic looks like it had more trouble dealing with noise than would be typical for a 1080p 20GB rip.

That's the fucking reason it's called "film grain"

so it's bay's fault? lol

but i doubt the print shown in theaters suffered the same flaw

i would motion compensated denoise the film grain and add static grain. probably get it to 8gb with x264 10butt crf18 + opus audio.

>That movie was filmed on 35mm

It probably did

>shoot on film
>scan it digitally
>add digital cg on top of it
why jewlywood are so stupid?
35mm film can get nowhere near 4k level of detail.

Why are you watching that terrible movie lol

if your fucking 1080p blu ray is 20gb and not a straight up remux you are a braindead nigger of outerworld proportions

post the original frame for comparison

...

>35mm film can get nowhere near 4k level of detail.
you're so amazingly stupid.

please stay away from the computer. you need to be 18 or older to use this site.

The DP fucked up it'd look this bad in theaters or on a 4k blu ray

>The DP fucked up it'd look this bad in theaters or on a 4k blu ray
gonna need a source for that, captain faggot.

That doesn't look like compression artifacts, really. It's probably from the source itself.

Common sense. Encoding can't introduce grain like that.

i watch 4k PSA rips, fight me

Grain is seen as a quality thing now because hipsters have confused themselves into thinking grains from old films were due to quality filmmaking instead of flawed camera lens.

Its a sad state of the world

That's wrong. Comouters rule the world and modern vidya has artificial grain effects. So they render grain and it ripples down into real life eg movies
