Testing out 4K video with my Panasonic GH5
So if you watch any of my videos on my YouTube channel you’ll know that I love my gadgets and tech, and I’m always aiming to improve the quality of my videos and my editing. A few months ago I purchased a Panasonic GH5, which is capable of filming 4k video at 8-bit (even 10-bit) at 50 fps. Now the main computer I use to edit my videos is actually a laptop for convenience, and sometimes it struggles with standard HD footage at 1080p from my Canon 70D, so I thought there was no way I would be able to process of render videos in 4K. However I was wrong.
Using Premiere CC 2017, you can setup what are called Proxies. This allows you to create lower resolution versions of your video for editing and processing, which then use the correlating full resolution versions of the video when you come to render. You can do this by enabling Proxies and setting up your own “Ingest” settings; I set mine at Cineform 720. When you import your large 4K files into your media library, the media encoder loads up and quickly starts generating the proxy videos.
This worked surprisingly well, and I even added a button to my editor window enabling me to switch between proxies and the full resolution videos when I was colour grading my footage. Amazing. When I finished editing, I rendered my video as normal and it created a full 4K resolution file which my laptop struggled to playback. I uploaded it to YouTube and it looks great.

I don’t think 4K is going to be completely necessary for me all the time, especially for vlogs etc but it’s great to know that I now have the option to use 4K video. A recommendation I heard recently was to film in 4K where possible, and downscale to 1080 as this created a much better quality video. I will continue testing this to see how I get on.
