I don't own XT2 but GH5 clearly have superior rolling shutter. Dynamic range isn't that big of a deal, and if you *need* that margin that both of them are "fighting" about you are looking at the wrong cameras anyway. Just grab the Alexa at the bottom and be done with it. *edit* The artifacts could be related to the temporal noise reduction

That does not look like a bitrate or bitdepth problem. But straight out encoder problem. How they did not spot or fix that is in development is beyond me. But so is the C100 temporal noise reduction.

I may be blind but I don't see any original files to download. No way of telling if the artifacts are there fault or not. On thing is for certain, the sample pic shows some pretty bad artifacts, does not look like regular compression or bitdepth error as you can see some noise coming through the stairsteps/area, mostly red channel. Areas with more information/detail seems fine tho. Would not surprise me if it's a bug that has already been corrected. One big benefit of 10bit is you need less noise to avoid banding, so you can have a cleaner image. A cleaner image compresses better so it's win-win. At higher ISO where it matters less I would rather have those bits put into resolution instead. A bit late now so Ill catch up tomorrow.

Can't find the link where I found the original answer to solve it. But here is a link showing how to fix it. Not sure if it happen to everyone. But when copying files to NAS it sometimes happened and sometimes worked. http://fredericiana.com/2014/10/16/finder-file-in-use/

Mac have some nice things, but the frustration of getting it to work properly is bad. Trying to copy file with finder? Nope you can't cause it fails at end of file because it is "in use". Yep, can't copy files that are in use. Good one OSX, good one. Thank you for ruining that 1h network transfer. That was an annoying problem, until I found out that when finder creates the preview icon it locks the file. Yep, the very program you are using to copy the file is the one locking it preventing it from being copied. And according to the internet it is a problem dating back many years but noone at Apple cares to fix it. This also happens when you want to delete files. I talked to a few Apple ppl how they handled it, turn out they just ignore the files that can't be deleted and just leave them there. All of them had experienced the problem but noone had the solution to fix it. The solution is to disable the generation of thumbnails in finder. I found the answer online and the comments section was flooded with thank you notes.

Well that's a disappointment that rolling shutter is so bad even with line skipping. Why can't they just include a 1:1 readout mode for 4k. Call it zoom and make it a feature. That would decrease RS and be useful at the same time.

You can get a seedbox, which is basically a bittorent client with disk space and good internet, once it is uploaded to it they can download as fast as they please. And if they want, they can help seeding too. Finding one that is meant for normal things might be harder as most is used for less than shady purposes. https://www.online.net/en is one example, you could use it to host your own file server if needed as well from what I see. 10€/month seems to be pretty common price. How much space do you need? *edit* If you go snailmail route please include checksum to see if file is intact when it arrives. I have used http://www.exactfile.com/ several times to generate and check files.

I would just use torrent based transfer, that ensures the data is correct when it arrives. You can even use your own php based tracker if needed. It's a bit more manual but could be set up with scripting to automate some things I guess. It is robust and won't complain if interrupted etc. You could even make or rent a "seedbox" if many clients are going to download the files. https://syncthing.net/ is a similar tool to sync folders except you have your own devices. Tried it a long time ago but have not dabbled with it since. Easiest would maybe combine it with vpn for a "local" sync to avoid opening things to the internet. https://owncloud.org/ is another option for private cloud, have not tried it tho.

Whatever you decide, add a checksum of every file so you can verify if it's intact or not. And make multiple copies so you can find one copy of a file that is not corrupt. I have used this and like it. http://www.exactfile.com/ Good to have for files on computer too. It's good to know that your source material is still intact later in a project or after transfer.

It it's just to an external monitor then connect HDMI directly to it? As for camera, studio camera without recording do go on for a lot longer on battery then the recording models. Or you could find a conference camera that could be remote controlled.

Just checked the Fuji Guys video and the AF is awful. it might work for 1080 but sure not for 4k. Too jumpy and keep changing. Could be pre-production so hope for better I guess.

So I should trust a site selling transcoder to h.265? The thing is that larger blocks means less bandwidth per area, and that means less bandwidth for grain. I don't doubt H265 is great for clean material but the codec simply can't do magic. It can only take data from one area and prioritize it to another. And a good codec only hides what you can't see.in favor for what you can see.

I would have liked ECC memory, but today's memory is getting good enough I guess/hope. The main reason for not using two or more CPUs is they don't share RAM. So it have to copy/move data between RAM banks if it wants to use a thread on another CPU. That may or may not be a problem depending on workload. As for "long term storage" I would use a filesystem with checksum and correction. Mainly ZFS running on FreeNAS. Data corruption is bad to have, not knowing about it even worse. Especially if .mov head or tail get corrupted ruining the entire clip.

In theory it's not a bad idea. In practice, it's likely more debatable. Large scale banding won't go away as all four pixels sampled would have the same luminance and would still show same stair steps. Now if the source was "noise shaped" you would gain some bit depth at the same rate as the noise is reduced (at least I theorize so). So you end up with maybe 9bit luma? But if it was proper noise shaped(dithered) from the beginning you would not see banding anyway.

To compare apples to apple you have to change exposure in Resolve too. You can by converting Rec to linear, change gain, then back to Rec. Or change whatever nonlinear space you are working with into linear and back again.

I don't get what you are after. Gain and exposure is not the same ting.(unless you are working in linear space) And clipping always change hue.

Well, The brightness/contrast nodes labeled Source/Out is where you input and output your video stream. The top row generates the grain needed and the bottom row is where is is applied. And where you adjust it by the Blend slider. 0.2 blend of WhiteGrain and BlackGrain is probably where you end up in normal content. MainGrain is, well main grain adjustment. *edit* The resolution of the grain layer is set by the Gray50 node. And the grain size is set in the grain node. The sharpen node is to get it closer to the 35mm scan and contrast node is to adjust the amplitude to match it.

Mostly, but clipping is a digital thing, and there is still some grain there. You only want to add a tiny amount. Try both, you can always turn off those two nodes. Also try both after compression.

Using just overlay will leave dark and bright areas clipped without grain. I made a simple filmgrain network in Fusion 8. I tried to emulate the 35mm v2 HolyGrain scan as my source grain. I think it's close enough. Use the blend slider on the composit nodes to adjust to the material and desired effect. BlackGrain and WhiteGrain adds grain back at the darkest and lightest part of the image. It will look bad if overdone so adjust carefully to add just a little grain, this will ensure that nothing is clipped at ether end, it will be monochromatic BW as grain at the extreme don't really inherit any color information. The levels nodes can be used to adjust how the black and white grain clips if desired. But I think that looks digital really fast. FilmGrain.comp

So they can do magic with skin tones but have the worst sounding intro ever, seriously that hurt my ears! A first poster magically posts the promotion video that have 71 views and raves about customer support. Sounds legit.

Totally found my answer on RGBW, it's crap. http://www.avsforum.com/forum/166-lcd-flat-panel-displays/2398506-rgb-vs-rgbw-lcd-4k-ultra-hd-designation.html

I started to look into this as well. After filtering out I don't see that many options at affordable prices. I want HDR in some form. And IPS with good viewing angle for sitting close to it. LG have some interesting options, mainly 43UH664V. However the panel is apparently RGBW with evory other row 50% offset, anyone have any experience with that type of panel, especially with computer use? The obvious benefit is higher brightness at full white, but giving up brightness of saturated colors. I have not seen one up close so I don't know if the pixels would be distracting or not.

http://argyllcms.com/ Whatever your calibration needs are I would start there ^ DisplayCAL mentioned above is a GUI for ArgyllCMS.

I have used Cobian Backup for a number of things. Can't really say how well it will handle your workload tho. And you did not say if you are using windows, mac or linux. http://www.cobiansoft.se/ Only thing I had is that things get slow when computes starts as it calculates size of source files and the like. No idea if that still is a thing.

The problem isn't as much 8bit vs 10bit I think but the effort put into compressing the data. Good compression takes a crapload of processing power to do, while bad just breeze through at realtime speed. If you have not, play around with Handbrake and change only the slider for compression efficiency vs encoding speed. It's under optimise video. Even at unlimited bitrade you will notice degradation in quality unless you add some effort to the compression work. Also proper dither made for the compression setting meaning you make the entire chain optimized makes a good difference.
