Shadow Blade cloud PC Xeon/GTX1080 for cloud gaming, cloud 4K60/8K video-editing

Posted by Charbax – January 25, 2018

French startup Blade presents their awesome Shadow cloud PC service at €30/month that streams a very powerful $2000 (equivalent) desktop PC hosted on their server powered by a high-end 8-threaded Intel Xeon server CPU with an Nvidia GTX1080 GPU, 12GB RAM, 256GB SSD (with harddrive/SSD storage expansion options available) running a full Windows 10 Pro desktop remotely in their server, using low-lag Internet technologies that they have developed, fast codecs (to have at least 15mbit/s Internet bandwidth available is recommended for a good experience), fast tricks that they have developed to make this all possible, to offer cloud gaming or high-end video-editing, 3D graphics rendering, audio processing, or anything else that might be useful to run on advanced PC hardware that you can think of, and you can then run that through client applications either running on their AMD APU based Shadow PC thin client that they offer to their subscribers (for a smooth up to 4K60 or 1080p144hz gaming experience), or you can run clients on a Chromebook, any Android phone, Android TV, Macbooks, any Windows machine, Linux, iPhone, iPad, their service runs on everything. Currently their service works well in France, initially it was just for French users who had Fiber to the home connections, but now it also runs smoothly onto any ADSL, Cable even LTE devices in France, the service is also supported in Belgium and a few other countries nearby France. Because for a good service, the user has to be within as few hops in the global backbone internet network as possible, to experience as little lag times as possible. Advanced professional gamers have tested this system and they have reported that they cannot feel any difference between the Shadow cloud gaming service and a local desktop gaming machine. The lag time are said to depend more on the speed of the PC monitor than of the internet back to their cloud server system. They are about to expand their offering to cover the whole of California as they are setting up a cloud server system right now in the Silicon Valley also. They plan to expand their services globally in the near future according to demand.

$2499 Panasonic GH5s interview (filmed with GH5s) better Low Light, better AF, DCI4K60

Posted by Charbax – January 12, 2018

Available to pre-order for $2499 at Amazon.com, Panasonic has improved their Low Light performance and their Autofocus performance (it looks like to me, after shooting this video, for now, compared with my GH5 videos that I am posting in the playlist here) on the GH5s compared with last year's Panasonic GH5 micro four thirds camera. They removed the amazing Sensor Image Stabilization feature of the GH5 though in this camera, they say as some professional users are asking for it to be removed, and they say also that is because they used a 10.28 Megapixel Multi Aspect Ratio MOS Sensor in this one. WIth DCI 4K60p support which is the format that I film this interview using the GH5s at. In this video featuring Sean Robinson of Panasonic USA, you can see the low light performance, the autofocus performance and you can see how it looks like without the image stabilization system. To me after shooting this video interview with the GH5s in a low light situation, it looks like the GH5s might have better autofocus performance compared with the GH5 (though I am not sure if this AF performance is good enough for my handheld video-blogging yet, what do you think?), as far as I understand, the better AF performance compared with the GH5 is because the Venus Engine 10 processor in the GH5s is able to focus more on performing better doing the autofocusing as it does not need to spend performance managing the sensor stabilization, noise reduction and downsampling of the 18 megapixel footage that comes with the GH5.
