I don't recall any other video so low from Destin's channel  :-\

He got a free server out of it  :-+

some talented youtubers were messing with video way before youtube (i.e. angry videogame nerd).

That Smarter Everyday video led me to a LTT video showing the Saturn V Instrument Unit. That alone was reason enought to watch it.

It did also show some post processing effects. So maybe LTT editors do more than just edit.

Yes, Linus did a great job on the Saturn V video, I was impressed.
It was very likely he had to write that on-site and shoot it, he mentioned they had to keep the place open late for him.

they shoot in 8K? I am sitting 1m from a 42.5" 4K screen. It has 4 pixels/mm (104dpi), i also have a 27" 4K screen with 208dpi that i can sit 0.5m from. I cannot see the pixels on a 4K screen. I would argue that youtube should limit it's output to HD unless the user asks for 4K. I cannot tell the diference between 4K and HD when I am sat 1m from the screen and the only reason i got a 4K screen was so that fonts would be smooth. Why even bother to shoot a youtube vide in 8K? at 4x the required datarate, oh I suppose it's some stupid fps rate as well. But I guess it's bragging rights and that attracts and audience - wow must match this channel is was shot at 4x the resolution and 3 times the frame rate my eyes will appreciate or my hardware can work at but sure it makes a difference.

For what I read, since I don't understand anything about video, most of people using the 8K cameras do that and then downsample the video to 4K. For what I read, again gives more info regarding the average of the colours in the pixels.





It's also used to crop and reframing, so basically they shoot 8K and crop what they want into 4K.



Again regarding what I read and listen, don't have any experience with video editing. And to be sincere after 4K I don't note any difference. The biggest I note is in close ups to a face of a person, you can really see the texture of the skin of a person and hairs in 4K compared with 1080p.

Still I note more difference in resolution in Animation, specially Anime/Computer FX Movie from 4K to 1080P that real life actors. In my honest opinion, 1080P in a good OLED TV with HDR multi zone looks way better that Normal 4K in IPS screens, correctly calibrated to DCI-P3

I understand why one may want to shoot at a higher resolution. I use a 24Mp DSLR but rarely use pictures at more than the 8Mp of my 4K monitor but yes in photos i may want to crop and do work on it which is best done at a higher resolution and then down sampled. For the same reason i have stitched photos froman 8Mp camera to a total frame of 50Mp with overlapping of each frame such as to double the data in the image but that is photography, a still photo where you can gaze at the image as long as you like. But in video all of these principles are a waste of time. Sure a shit 8K camera will get you good 4K and shit 4K will get you good HD due to downsampling but if you have a very good quality 4K camera you do not need to down sample. As it is multiple elements on the sensor make up each pixel in the image.

Exactly, that's how I think too, specially when I jumped from the Nikon D90 I had for more that 7 years to the D7500. First the increase of file size, but with that the extra colour definition of the sensor and the requirement to best framing and a big allowance to crop when things don't go as I wanted.

Photo were you spend a lot of time looking is more important that quality of high definition and big resolution that when video were the image moves and that high quality is not always perceptible.

I really doubt if the price of this specific camera in question (the red 8k) will be negligible to a really skilled camera operator..
lesser.... sure...
insignificant / negligible... certainly not
I dont know if the camera operator for LTT is a seasoned red operator.. and if that  was a recruiting criteria for hiring him.. If so, then maybe the gap between the camera and the operator reduces.. otherwise.. the camera is still, potentially, much more of a expensive equipment than a operator.

There is another angle to having all that gear, which Linus pointed out on one of the WAN Shows. They objectively need to employ people, there is no way around it. And people need to be kept interested, otherwise they leave. And part of that increasing "toys" collection is that camera operators want to work with different and better gear and improve their skills.

And the cost of that camera compared to a salary of a good worker is really negligible.

Linus Media Group is much bigger than his website shows - and even more if you consider Floatplane (LMG is the sole owner AFAIK). In a recent WAN show I seem to remember 35-36 employees? They had 20 employees a year ago https://www.reddit.com/r/IAmA/comments/8839ad/we_are_linus_tech_tips_a_youtube_channel_that/ and had 6 job listings some months ago, and posted another two vacant positions recently.

All new hires get a 6 month grace period where they are not revealed to the public.

Hard to tell what the real number is at this point.

Of little to no consequence on Youtube

Sure. But how about some basic camera skills to get framing right in the camera to begin with, then no extra editing step needed.
Zoom is handy, but most content doesn't really benefit from that much.

If oyu upload in 4k then Youtube encodes at a higher bitrate, so less compression artefacts. One advantage of 4k uploads.

with the camera resolution it's the same old "my dick is bigger than yours" thing. What next? 16K Somewhere on youtube is a very good video by a guy about the real resolution requirements and he shows that HD is adequate enough so 4K is plenty and even editing in 4K to show at 4K or HD is fine. doing it in 8K is just bragging rights for the camera gear, their dicks and the the computers required to process and store that. Of course some people will watch the channes "because it must be good if they use all that gear" and are oblivious to its vacuous nature in terms of actual content.

Well, they have the Techlinked, which is researched, scripted, shot, edited, and uploaded the same day. He has employes, meaning they work 9-5, as I understood they are looking for faster equipment, cause they cannot go home until it is uploaded. If you go to their website, https://www.linusmediagroup.com they only list 4 editors. The clickbait title could have been a clickbait. People take vacations, and the show must go on? And as I understand they also upload to chinese youtube.

And the RED camera: Wouldnt you have one? It is cool tech.

One of the best channels about video production is Filmaker IQ
Brilliant videos.

Well, they have the Techlinked

I included that channel in my 3 channel total video count, 1.5 videos per day average for all 3 channels combined, so 1 video every two days on average for each channel.

Really? what is the bitrate per Mp ? the advantage to 4K is that you can't see the pixels so even at an equivalent compression rate to HD of data rate to pixel count you can't see the artifcts that may still be there because they are too small to see. Plus the more pixels there are the more the adjacent ones are alike so easier to compress. You may as well do HD at the same bit rate as 4K and it will look equally sharp.

A good human eye can distinguish 2 dots 1mm apart at 1m, I am 1m from my screen and I have 4 dot per mm. 2 dots per mm are fine for video and I usually set a youtube video to HD even if 4K is available, but the shooting and processing in 4K will have benefitted the quality as there are 4 dots input to every dot of output, but 8K is just silly unless you want to crop loads in which case learn to shoot.

At the end of the day 4K streaming will just increase the load on the internet and servers, is it really worth the electricity being used to power these wasted resources? we are supposed to be watching our carbon footprint and yet we are drawing data and the associated energy cost unneccesarily just for an ego boost. I am watching youtube in 4K get me! really? I could not even tell that i was watching 4K the first time I did, I don't miss it watching in HD.

16.5 stops of dynamic range is what I heard from the 140K video. It sounded too good at about 3 stops more than the best full frame DSLRs. Naturally it was double shot.

Still good if you need it and know how to use it. Some interesting discussions about various aspects of video production there too.

again for indoor shooting lots of dynamic range is not essential and with all the background work they are doing they must be setting up lighting properly?

Youtube don't tell you. But people have done experiments and the same footage uploaded in 4k looks better when played back at 1080p then if you uploaded it at 4k. It must be allocating a higher bandwidth to the internal 1080p than a 1080p upload.

The detail comes out in the compression (i.e. moving images) rather than actual pixels in static images.

Which is what i suspect and recording and processing in 4K is not excessive, I'd just not bother to whatch in 4K and risk buffering. But 8K ? that is just silly for talking head videos.

Certainly sounds silly for Youtube viewing. But I suspect people filming in 8K are more or less expecting that someday they could "sell" their videos to TV channels or something...

a TV channel at over 4K? nope. look at the resounding success that 3D cinema is......., Oh, It not, is it? I think cinema could use 4K but not much more and TV only needs HD maybe 4K, I'd settle for 1440p but not 2160p. It may come but what TV station wants 8K? lots of linuses video's are time sensitive, at best they may have historic value one day.

At least a few news agencies in China has been shooting at 9k for producing in 8k. Currently the public feed is mostly 1080p25 and 720p25 with a few 2160p50 pilot channels available, but the agency managing broadcast television is awarded a 5G license for using that technology for OTA television with 4K and 8K public feeds.
