Haha, nice try developer from Netflix HQ

I have never seen those questions answered because it's a secret sauce that the streaming platforms would patch immediately if it were published. In general though, my understanding is it's older versions of apk's on rooted android devices with exploits that allow for harvesting the actual cached files, or in some cases the apk is deconstructed to get access to the API keys so that the files are downloaded directly, though that's risky as it gets easier to detect a single key doing a giant pull of files faster than someone could reasonably watch the shows.

It's a secret -- otherwise the streaming services in question would immediately patch the vulnerability

WebRip is basically exactly that: capture audio/video during screening. WebDL is secret magic to tickle the streaming service for the files it sends to the browser during streaming.

With your capitalisation of "rip" there, I nearly had a heart attack thinking something (implausibly) had signalled the end of rips from streaming platforms lol.

If your web browser can play it once, it can play it any number of times. Look into Widevine decryption. Basically you load the video in a special browser, save both the video and decryption keys, then decrypt the video file.

When it's discovered it stops working. Rippers have custom reverse engineered tooling and keep it secret.

A more crude variation than using dedicated ripping tools is using yt-dlp. If you need a login to a service, you can pass the username and password or login with a browser and pass in the browser's cookies. I've personally heard you can do that to at least rip sub-gated Twitch VODs, anyway.

I don’t know about a guide, but I believe it’s still possible to rip 4K HDR using an HDCP downconverter . HDR/DV data is included over HDMI, the problem is that it’s all encrypted (along with the 4k stream itself) with HDCP 2 which isn’t publicly broken yet. This box (and others like HDfury) does some tricks to force a fall back to HDCP 1, which has been broken for a long time, so you should then just need a capture card that supports it.

Scene releases may have better/faster techniques depending on the streaming platform, but they probably wouldn’t talk about them if they did.

Yo, what you are asking for is called webDL. webRIP is screen recording and there are quality differences between them. If u are interested in webDL'ing check out https://cdm-project.com/explore/repos. Also check around videohelp forums. I won't mention anything else in here because it would put me in danger legally.

HDMI splitter.
