eGPU for video processing on a laptop – Does it make sense?
majoraxis replied to Don Kotlos's topic in Cameras
Here's article on this top regarding us with older Mac Book Pros https://egpu.io/thunderbolt-egpu-for-mac-2017-update-macos-sierra/ I was thinking about the getting the Akitio Node Thunderbolt 3 https://www.akitio.com/expansion/node I wanted to pair it with the ADM RX480 and my 2014 iMac, but it is not clear to me that it will work or secondly that it will be that much faster than the 4 mb AMD 295x GPU already in the iMac... Anyone using and iMac with and Thunderbolt eGPU? Thanks! -
@Imackreath - Perfect - thank you!

@Imackreath. If you could let me know if the EX Tele Conv mode that is supposed to have a 3.1x crop factor for movies, records in 4k and looks to be 4k resolution, that would be greatly appreciated. Thanks! Mark

TSA bans cameras in cabin baggage, on flights to the US from 13 countries

Do you lock the door to your house when you go to bed at night? If so - why? I do because I feel safer. Am I realistically in danger if I don't lock it and I am fast asleep and defenseless? Maybe, maybe not. Do I want to find out if I am being overly cautious? I don't, so I continue to lock my door at night when I go to sleep. Am I xenophobic? Maybe, maybe not, but I sleep better at night with my door locked regardless of if my perception of what is and isn't a threat is realistic (or politically correct.) -
When I think of cinema, I think of being sucked into the story and not having my attention torn away by some flaw in the story, image or sound. If the selected camera does not distract or detracted from the story being told, it is cinematic enough. The said from my personal experience shooting with different types of camera I found that the BMCC with an old canon 1' c-mount TV (15-150 f1.8) lens and other c-mount primes gave me what I would consider the most cinematic image as compared to the GH1, NX1 and the A6300 with their compatible lens. Order of importance for me is: 1. story and actors 2. lighting, composition and lens selection 3. camera and sound equipment. 4. post production

The Neway CK1014S should do 4K 60p with a resolution of 3840x2160 with a 10.1" IPS screen. There is s thread about it at PV here: http://www.personal-view.com/talks/discussion/15683/neway-ck1014s-10-3840x2160-ips-hdmi-2.0-and-3g-sdi-monitor/p1

The NX1 has great 120 with very low rolling shutter. The auto focus works OK with the Samsung 45mm. The NX1 is pretty tall/large compared to the a6500 if you are trying to fly on a gimbal. I would strongly consider the GH5, though AF performance is not quantified as far as I am aware.

Hi, There is a thread on Personal-view that has introduced a free set of input and output 3D LUTs to make video files respond to color correction like they were shot in RAW. These are free and available at http://www.logarist.com The video below explains how to configure your video editing software (in my case Resolve) so that exposure compensation, contrast and white balance (via offset) behave like they are working on a RAW video files. I tested it on files from my Sony A7RII with shot with the Still color setting and Cine1 gamma (as recommended on Logarist.com) and it worked great. I tried the same CC settings without the input and out LUTs and it still looked ok, but not as good, especially when there were any exposure changes. Besides looking better after color correction, the process of color correction was easy to get great results quickly. If you are looking for great color with 8-bit video files from your Sony cameras, I highly recommend you try it! Mark

Things I learned or got reminded of by this video as prosumer camera user. 1. Get your skin tones as close to perfect in the camera as you can and don't wait for post. White balance and tweak the picture profiles etc. 2. Grade in your camera's native or raw format before transcoding. Makes a case for recording to ProRes if you plan to transcode to edit before grading. 3. Bad glass and poor or wrong filters can mess up the look of way skin reflects light. Makes a case for straight ND as variable ND's can make an image look a little flat as they are made from polarizers that mess with reflections. 4. The sum is greater than it's parts - High res, slow motion video with great color/skin tones, low noise and high dynamic range is a hard combination to beat and something I and most other filmmakers want in their tool set.

I have 3 native Sony lenses that I use: 24-70 2.8, 35 1.4 and the 24 1.8. Unless it was in a low light situation, I would start and probably finish shooting with the 24-70. The image is solid and cinematic, it has weight and dimension. I looks great wide open at 2.8. I like having the ability to zoom for emphasis or necessity. I would start with this 24-70 G Master and then when the A7S III comes out next year - your full frame, low light, b-camera needs will be met when you buy one and stick the 24-70 GM on it.

@Andrew Reid Re: "AF works quite well with Canon glass" Would love to see an AF comparison between the G85 w/ Canon glass, A6500 w/ native Sony glass and 1DX II w/ Canon glass as well low light and rolling shutter... But for now, does the G85 with adapted Canon glass compete with the A6500 with native Sony glass regarding AF? If so, with with what adapter? Thanks! Mark

I'm very impressed with the Sony 24-70 G Master. It appears to be parfocal, focus by wire works well and autofocus with Sony A6300 and even the A7RII to a lesser degree is very good. At the long end, it has nice bokeh wide open with a 3D pop to it. Resolution and color are outstanding as well.
-
The Sony Zeiss 24 f 1.8 is also excellent e-mount aps-c prime lens. It can work as near macro lens as well - the one I have can focus as close as 3.5". I took off the plastic inset via loosening the 3 tiny screws at the back of the lens and this allowed me to use it with the A7R II in full frame mode with a 1.2 clear digital zoom to get ride of most of the vignetting. There is more distortion at the outer edges than with a full frame lens. Anyways, I would love to have the a9r as Andrew describes with the addition of on sensor variable ND and of course 4D autofocus.

Clinton Cash is the type of documentary that, at the end you read the credits and find out that they wind up in prison. The ending is not yet written, so they may get pardoned. We got lucky as to not have this level of coruption headed to the White House.

BH Photo Video lists the GH5 without price or release date
majoraxis replied to Michael Ma's topic in Cameras
Looking forward to this camera. I hope they will have added in body image stabilization by the time they release it. That said if it has super low rolling shutter, I will make do without IBS as in-body 10bit 4:2:2 4K is irresistible in this form factor, size and weight. -
Because Sony is continuing to sell the a6300, I have hope the rolling shutter on a6500 will be improved but not specifically promoted as Sony does not want to talk bad about a current product, I also hope the same is true for over heating.
-
I believe less jello makes it look better when stabilizing in post (of course!). So, probably near global shutter with post stabilization would allow you to tune the organicness of the motion if you want. I think that is one of the reasons I like the look of the NX1 at 1080p. Here's a comparison video with different amounts of rolling shutter.
-
Thanks Sony, for coming out with this before I purchased an G85, when the a6500 is really what I wanted in the first place. If they just improved the RS over the a6300, then I can live with managing the over heating (hopefully it doesn't) and I think this will be a camera platform to build on for a few years.

I use the Blue Yeti and it works well. The sound is acceptable with a little post processing in Reaper. Also for consideration, if you have a preamp that can interface with your MacBook is the, Monoprice 600800 Large Diaphragm Condenser Microphone: http://www.monoprice.com/product?p_id=600800 It get's a great review here: http://tapeop.com/reviews/gear/96/600800-large-diaphragm-condenser-mic/ Or Monoprice sells a USB version the 600801. http://www.monoprice.com/Product?p_id=600801 You just need to plug your headphones into the MacBook with the 600801 rather and into the Yeti body as with the Yeti. There's is a video on the Monoprice 600800 that lets you hear how it sound and there is also lots of Yeti vs XXX on YouTube.

@Ed_David You do fantastic, inspirational work. Your ability evoke emotion and shape perception is beyond description - your passion comes through in your work and I completely respect that. @iamoui Thanks for pointing out trump being used as a verb. Clever. Kind of like "Hillaried" from the Urban Dictionary: http://www.urbandictionary.com/define.php?term=Hillaried To fail spectacularly at something where success was all but assured. From the resounding defeat Hillary Clinton took in the Iowa caucus. Dude 1: I thought I was going to ace that math exam but I totally hillaried it. Dude 2: That's your problem, you were so confident, you didn't study. So of course you were hillaried.

Thanks for the review! I was wondering about this light and this was informative.

@ Simon Shasha - looks like the IKAN DH5e and the Neway CT500HO are the same monitor. It is very lightweight without the battery and it has function buttons and a push-dial-select-encoder-wheel so it can easily be run without the touch screen with a loupe attached. I am thinking seriously about getting the GRID 5" EVF loupe https://www.gridaccessories.com/products/grid-5-0-viewfinder/ (which has a glass diopter, I am told) and is about $200, but I want to wait to see what Neway offers as an optional loupe that is designed specifically for the CT500HO before make a purchase decision. I also don't know if the GRID 5" has the same exact aspect ratio as the CT500HO as it is designed for the BMCC.
-
@ Simon Shasha - Great idea! I have similar plans, but for the Neway CT500HO. I purchased mine off Alibaba, but you could also get it from Personal-View under deals for $289. Anyways, if you want to use your regular 3" EVF it has and EVF mode which shrinks the images so that my 3" EVF covers the top and bottom but does not cover the sides completely, which is not a big deal to me. Looks like the EVF mode images covers more than have the screen so the resolution is greater than 540 x 960 might be closer to 720. Here is an image that gives the specs... Neway also make a 5.5" with SDI but it does not natively handle 4K via HDMI like the 5" so the Pixel to Pixel resolution is 1/4 as resolved as on the 5".

Hi, I have been looking for an combo EVF/monitor. The SmallHD 502 and Sidefinder was the functionality I was hoping for, but the price had put me off. Then I stumbled upon the SpectraHD 4 as a potential alternative. The current price is $706.29 new on ebay (or $749 from F&V/Adorama/Amazon) with the loupe - so it is worth consideration IMHO. http://www.ebay.com/itm/371278169162?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT Here's a review: Looks like they added waveform via a firmware upgrade as was hoped, now if they could only add a LUT...

Sorry being over optimistic in my last post about using simply brightness, contrast and saturation to dialing the color correction. Seems like the S-Log 2 or S-Log 3 LUT (in Premier) is a good starting point as an input LUT and adjust from there. Dialing in your monitor with brightness, contrast and saturation in a controlled light situation can be a benefit, but because of the log nature of the footage, changes in exposure and lighting change it perception of contrast etc so it will not be reliable without LUT under non-controlled lighting situations. It's a great profile that is can be more easily monitored with non LUT monitor as compared to standard S-log profile, but caution is advised when dialing things in with brightness, contrast and saturation in post or with external monitors due to the log nature of the footage.
