We can capture/record cut/edit videos with lossless formats without problems.
Do we need Cineform and Prores lossy compression in the 2020s?
These codecs are for people, who have slow internet speed for video sharing sevices (under 2Gbit/s) and/or who have not enough big storage. Buying some 16TB fast HDDs are not expensive in the 2020s.

Short Answer: YES, we still need them and will continue to for a while.
Long answer: Hardware manufacturers (cams, dvrs, atomos, gopro, etc) still encode their captures with these codecs, and we need them for compatibility of workflow projects. Those codecs also support many features (RAW, HDR, Stereo3D, 444, etc) and platforms (PC & Mac) that many of the OP's tauted lossless codecs (HUFFYUV, Lagarith, UTVideo) do not. Also, while I ultimately would prefer that we had an cost/royalty-free, international, standards-based suite of codecs to use, the large corporations that have created and provided these closed-source (and largely, free) codecs still have better support than the open source lossless alternatives. And, those codecs often do now have their own lossless capabilites.
Also, stop being so pie-in-the-sky: only a very small minority of users has consistent >2Gbps internet, and 16TB SSDs (which would be very necessary at data rates required for HD or especially 4k higher end versions of those codecs*) cost $2500-3000.
*3840 x 2160 x 24bits x 60fps = 11390.63Mbps. or 12Gbps. Even with a generous compression factor of 2.2:1, lossless codecs could only drop that down to 5Gbps.

Also, there are potential compatibility issues with lossless compressed formats (such as UT, lagarith, huffyuv) with host programs. They don't work in some programs like Resolve, FCPX . If your projects involve other people, a standardized widely compatible format like prores is going to cause fewer headaches (even with the drawbacks of using prores)
Quality issues - Most professional programs do not treat YUV lossless codecs as lossless (they get converted to RGB using standard range) . You get highlight/overbright clipping. That can be worse than using a lossy codec that preserves the range and gets treated as proper YUV
So it' s not just a codec issue; it's also a how-the-codec-is-used-and-in-what-program-issue . None of them are perfect, they all have pros/cons in various situations -
good points, @pdr. I've encountered those inter-app compatibility issues that you mention. Huff & Lags in particular. And I've seen versioning differences that cause problems too.

But why do we need them, really? Small light weight mini laptops are capable to capture of lossless Utvideo 4K@60p recording via small 4K HDMI-USB3 converter sticks. So you can record the full lossless superb quality with a very easy way, even during walking on the street!!!!

The answer hasn't changed just because you repeated your question.

But Youtube is the be-all / end-all of video
If you have a channel you are a big time broadcaster, if not you are nobody, even if you are a licensed OTA channel
Cornucopia, poisondeathray do you have big time YT channels?

WTF? ProRes422 files are huge! (Have you ever actually used ProRes?)
If you have a sippy straw for internet, you need to stick to compressed H.264. If broadband isn't adequate for ProRes files.
I never used Cineform, and was a stop-gap format for HD shot video 10+ years ago. DNxHD and ProRes, or H.264/AVCHD, own that space now. So I'd agree, Cineform probably isn't needed now.

Only 1 thing matters: How many people can watch a video. And YT and vimeo the only platform for 4K video for mass publicity. Nobody will find my video in my own website, wo do not know the name/URL of my webpage.
And yes, if I upload lossless video to YT, the quality will be better too. -

When I capture a video with my camera with UT-video to my mini laptop, and I cut it, and upload it. When the file was uploaded and touched the YT, it will be mathematically exactly the same as the my camcorder's HDMI signal was. It is a fully lossless process. It is the perfect system. Only the YT compress it.

It depends -
Most cameras have noise - and lossless codec will retain that noise, it makes it more difficult for YT to compress, resulting more compression artifacts. The viewer streaming quality can be lower
If instead you preprocess the signal (either filtering, or even a lossy codec - essentially the codec is denoising in that latter case ), the end result on YT for the viewer can be better. If you preprocess it properly, you're making it easier for YT to compress, this can result in higher signal to noise ratio
There are tips and tricks people use for YT to help compression, resulting in better viewer experience, fewer artifacts (even though it's still bad, it's not as bad) -
What about Neat video, the state of art noise and grain remover?
Why do Hollywood love and obsessed with video grain in such a degree, that all films directly contain grain? Even you can buy video grain templates for the movie idustry.
Is it true the video grain is necessity to enjoy movie and long videos? Without it the picture is boring for the audience. -
NeatVideo isn't state of the art. It had it's place in restoration, some 15-20 years ago. But Avisynth eventually beat it -- crushed it, squashed it, pulverized it. NeatVideo is like using a hatchet to perform a heart transplant surgery. Sure, it can work, but there are quality consequences. The main issues is that it's so overaggressive at all times. Avisynth is the scalpel.

Film grain is not the same thing as camera digital sensor noise . The grain look of different film stock is completely different.
Technically if you shoot something on film, that grain is noise, because the reality when you are there , there is no grain floating in the air.
But on digitally shot "films", grain is often added in post production on purpose - so in that case it's not "noise" in the film makers' eyes. It's wanted and a form of art
Whether you like it (or not) is another matter.

Grain has a functional purpose too - it covers up banding patterns in 8bit consumer space. Dithering is a form of noise that is added on purpose. But banding is less of an issue with 10bit becoming common among consumers
In visual effects, it helps to "cover up" roto work seams, rig removals and other defects. VFX artists love clean shots, that get grain added later - it conceals problemsLast edited by poisondeathray; 27th Dec 2020 at 11:02.

Why are you consistently such an a$$hole in every conversation?
Is it not enough just to talk tech?
