3of3 4K60p Panasonic GH5 handheld sample footage, testing 5-axis, autofocus in manual mode

Posted by Charbax – March 20, 2017

Here's my third attempt at making a sample footage at 4K 60p using the new Panasonic GH5, with the help of one Panasonic staff, he used what he thought could be the optimal settings in manual mode to try to demonstrate the 5-axis stabilization, the auto-focus always following and tracking my eyes and face automatically, focusing on devices that I hold. You can download the original 4K 60p 150mbit/s MP4 camera file here on Google Drive.

Posted by Charbax – March 20, 2017

Please try to ignore my big mistake in not controlling the Shutter speed in this video to prevent to the terrible flickering of the indoor LED lights once we enter the building. I am very sorry I didn't try to adjust the shutter speed while shooting or before hand. I also tried but I couldn't find any easy and fast Anti-flicker post processing options in a video-editor. So here it is, I publish this video as I filmed it anyway. You can still see the GH5's performance in its 5-axis stabilization, auto-focus, color quality in 4K 60p mode. This video features Interview with Kevin Walker of Panasonic UK and Nick Driftwood a photographer who has been testing out pre-production GH5's over the past 3 months and you can see some of his GH5 samples at https://youtube.com/driftwoodtv and https://vimeo.com/user2930807 I'm sorry I didn't ask Kevin or Nick to help me adjust the Shutter speed while shooting this video when I should have better noticed the flickering in the viewfinder.

Posted by Charbax – March 19, 2017

Filmed on Panasonic GH5 with manual settings (in shutter priority mode, 400-iso then trying to change the iso setting) filmed with Kevin Walker of Panasonic UK at The Photography Show in Birmingham UK. As this is my second time trying to use the camera, I have probably not set all the settings just right, and this was shot on a pre-production model with possibly a non-final firmware for now, please check back later as I will post other samples that I shot with the GH5 today using other settings as I was trying to achieve perfect auto-focus, perfect 5-axis dual image stabilization, perfect anti-flicker, perfect brightness, perfect colors and etc with the types of handheld always moving camera movements that I usually do in my video-blogging. Check back a bit later tonight as I will attempt to de-flicker the first 25-minute video that I shot with the GH5 in its more default P mode but where my shutter speed was set incompatible with the indoor lights flickering too much at the show. I will also try to upload a couple more samples that I shot on the GH5 in 4K 60p. You can download the original 4K 60p 150mbit/s MP4 camera file here on Google Drive.

DisplayPort comes with Qualcomm Snapdragon 835 with alt-mode Type-C directly on the SoC

Posted by juliusaugustus – March 2, 2017

DisplayPort is a standard for high resolution diplays. DisplayPort 1.4 can support up to 8K resolution at up to 30 hertz on a single cable and 60 hertz over two cables, here showing it off running on an upcoming announced Dell 8K 32" display. DisplayPort can also support HDR or high dynamic range.

If a device has USB type C and the necessary hardware it can output displayport video through Type C. Through USB Type C a device can be charged while outputting video and being connected to a USB hub. Display port alt mode can switch to HDMI for HDMI displays. The Snapdragon 835 has displayport functionality so more devices in the future should have it. Mobile devices in the future could potentially Run multiple display monitors through a dock.

A dock using High Bit Rate 3 (HBR3) over DisplayPort 1.4 can output to multiple 4k monitors.
