Windows HDR is really bad, macOS HDR is much more advanced btw. Another thing that many are missing is that DolbyVision does absolutely NOTHING for you if your TV is matching or is better than the monitor the content was mastered on, its great for 300NIT "HDR" Displays but thats about it really..

as a dolby vision DI/mastering engineer I would love to invite anyone claiming HDR looks bad to visit me in my mastering suite and watch HDR on a proper HDR monitor with properly mastered content. its really eye-opening.

had to adress what linus said about not understanding the difference between high luminance SDR and HDR. I found this interesting because back when HDR came along i was i college for media engineering and I had the same thought. (i an going to ignore wide gamut for now) If my display can show 0 to 1000 NIT SDR its just as much dynamic range as a HDR display doing the same . And this is all correct. Also you can encode abritrary amounts of source dynamic range in either HDR or SDR, you can make them look exactly the same, and thats also true. If you have the theoretical display that can do 0-1000 NITs there is no difference if you map the signal to a PQ curve or ye old gamma 2.4 curve. so yes it will look the same But now comes the part that makes HDR interesting and that is the difference between Absolute and relative encoding. In a PQ(ST2084) file luminances are encoded in a absolute way, so if I - in mastering set the luminance of the sky to 400NIT, it will be displayed at 400NIT on the consumer side, If I set skintones at 50NIT, again they will be displayed at 50NIT. Or at least the consumer display will try its best. SDR is relative, so while you could say my full signal is 1000NIT, and thus match my HDR monitor, some other display might only do 150NIT, thus the image would look vastly different on that screen. This is basically what HLG is as well... So HDR isnt a scam, its more about how stuff is mastered and the included metadata and downmapping on less capable displays. If you look into displays the LEDs have their own curve from off too full luminance and all the TVs logic is doing when switching from HDR to SDR is providing mapping to the native Backlight/OLED EOTF. and then the reason why many displays cant go as bright in SDR is probably down to power consumption and cooling, as you will have a lot of sdr content living in the 80-100% signal range, a monitor that can do a small window of 1000NIT would exhibit crazy dimming between sdr images if they drive them this hard so i guess they limit them, otherwise bo reason - we use high luminance SDR monitors a lot for outside use , they exist. the sony PVM x2400 for example can do 1000NIT full screen all day, and its a single layer LCD without local dimming with SDR content.

Doesnt really matter what OS the machine runs on, it just has to be 2U rackmounted and yes I cant get away from macOs because of required software and hardware that I need for my job , but I could use it as a headless linux server also.. doesent really matter as it´s the case I am looking .

thats what I am doing now with a combo of macbook and alienware laptop that does the heavy lifting, but I need more power in a single machine to get my job done, other than buying a iMac Pro that is...(which I am not going to do)

Did not know it wasnt allowed.. edited post because the OS isn´t relevant to the topic of finding a case

hmm no, I am fine with running a hackintosh, thats not the issue Looking for a case

Thanks but a Mac Pro is not really 2U rackmountable

Hey, due to apples lack of care for people like me.. I am looking at building a rack mounted pc... I Want to put the whole machine in a 4U rack flightcase, so it needs to be 2U + 1U for the UPS +1U for a drawer, keyboard e.t.c . Its going to be used for mobile transcoding and offloading of video files using Davinci Resolve. For fast transcoding I not only need a beefy CPU but also a GTX1070 mini or similiar. I also need to fit at least 4x 2.5" SSDs in the machine, if possible hotswappable with caddys in the front.. The Node 202 albeit not rackmountable, gets me alsmost there is is actually smaller than a typical short 19" rackmount case, but I can´t find any 2U cases that fit my requirements, anyone has a idea?

Hey everyone, I am pulling my hairs out. i have a asus x299 ws pro/se and I cant get any fan controlls, cpu fan is in cpu1, it spins but wayyy to slowly once I overclock a bit it thermal throttles. Ai Suite shows 0 rpm, bios doesent have any fan controlls (that part is just.. missing) deep in bios I found a page where it showes me all fans and there it shows 400rpm with no way of changing it. any ideas or defective mainboard? oO

Great video, exactly what I had observed, although you should try running a Dual CPU configuration with dual or tripple TitanXP, We have seen around 34fps 8K full debayer on a decked out HP Z840 with 2 GTX 1080 .

So we do on set dailies and we already had some 8K weapon shoots to handle and it was always a big struggle especially when the client requested full debayer on set. Most of the time its 8K full debayer to 1080p ProResLT or DnxHD, with our main rig (8core xeon and dual 980ti) we see around 5fps max when transcoding. (in resolve and redCineX) Last shoot we rented HP Z840 systems with dual 12 core xeons and dual quadro cards and we got around 30fps on each machine. RedRocket X card did actually make everything slower. So now I was wondering, how did the Z840 manage 30fps and our rig bottoms out 5. The 24 cores are obviously better than our 8 core machine but not by that big of a margin. Maybe its the quadros? I would really like to see some guys with crazy rigs to do a little benchmark and post the results here, that would really help us out in deciding what to buy next. That would also be a great project for Linus as he has 8K reds and the hardware to test it. So if you want get some 8K weapon footage run it through redcineX or resolve at full debayer and let it render some 1080p proresLT or DnxHD120 and post the results , lets see who has the fastest ;-) In the end we would love to break the 60fps "barrier", and we are even willing to go all out quad CPU for this.

Hello, I just bought a Alienware 17 R4 and I put in 2x 500Gb Samsung 960Evo NVME Drives in Raid0 (for Cache) and a 1Tb Sata SSD (for boot/Programs) . I am running CentOS. But I need some external storage, I will often need to take files from my Desktop (12Tb Raid 5 HDD ) to my laptop, sometimes a couple of TB at a time, It will be used for Video work (compositing/3D grading and online editing) So I need both speed and reliability. While I am very happy with my Raid 5 Setup, carrying something like a Pegasus R4 would be very difficult. w I have been looking at quiet a few options, and so far the best would be just to get a 2Tb NVME SSD, sadly they do not Sell NVME to USB or Thunderbolt enclosures only Sata to usb which would max out around 500Mb/Sec, not good enough for me, Ill be working with huge multichannel 32bit EXR sequences mostly in 3.4K or ArriRaw Opengate. I want to see at least 1Gbyte/sec read speeds. I have heard many bad things about SSD in a raid environment, a quad 2.5inch External raid stacked with 4x 2TB SSDs in Raid 5 should be speedy and portable and reliable, but there are many problems with TRIM and stuff like that.... Does anyone know anything else I have forgotten? Too bad they do not make RAID NVMe enclosures, I would just get 4 Intel P600 and call it a day.... in an ideal world I would like to get the following : - at Least 3Tb usable Space, more would be nice... 6Tb at most is what I would need. - 1Gbyte/Sec READ speed at least - 500Mbyte/s Write Speed at least - Reliable (could live with a good backup solution (I have a 12Tb NAS that I could expand) if you have a crazy Raid0 Plan ) - maximum 2K€, less if possible. - Portable (needs to fit in a Backpack type situation.) - Thunderbolt 3 or 2. Let me know if you have a good solution in mind.... Right now I am running 2 WD Black 6Tb in Raid0 but thats simply not fast enough, I always copy everything I work on to my NVME Raid0, big hassle and I want to keep them free for caching. (Nuke eats ups storage... and Flame needs a very quick main storage for storing everything uncompressed.....) . For my main Backups I have a LTO7 drive.

yea ive seen the naples stuff, but at this low of a clockspeed its not really that usefull for me sadly, I would need something in between those 2 ..

I haven´t looked at AMD CPUs since the opteron launch way back so I got a couple of questions. I ususally upgrade my workstation once a year or so, always killing the biggest bottleneck that I have for good value/perfomance parts. Currently I am running the 8 Core Extreme i7 on X99. 128Gb Ram and 4x GTX 980ti adding to that a 40Gbit NIC and some other PCI-E stuff.. Anyways, I want to upgrade the system later this year and I am thinking of going with AMD this time, looking at value/performance those ryzen chips sound pretty awesome to me, although I would need a more workstation/server oriented chipset that supports more than 28 or the 32 Pci-e lane, my i7 has 40. Is there anything they announced in the Server space that I missed? AMD was always in the game with Dual opteron systems as I remeber, maybe we will see some dual Ryzen systems in the near future? Just imagine Dual Ryzen 1800X "Server edition" for like $1000 Each. they would kill the Xenon in an instant. and it SHOULD be possible. I am scared that Intel has some weird features that makes it impossible for big server manufacturers to go AMD, something like that whole virtualisation crap for ESX servers or something. What do you guys think? will AMD go professional or are they just going to target gamers?
