What’s the advantage of 4K if you don’t have 4K playback gear?
To the videographer?
To the still photographer?

You can pull 8 mb stills out of 4K video on my Canon if you need to do that. But you are chewing up a lot of data shooting 4K video... Personality I am not a video shooter.

Same here with my Panasonic TZ100. VLC media player will do the job. Do a search at top of the page for previous UHH threads.

I have 4K TV. I can shoot 4K with my Iphone 6S or my wife's Galaxy S8 but...
I can't edit it. I can use VLC to play it but I don't have a powerful enough computer to play it well. When I hook up my Dell laptop with 6th generation i7, 16GB RAM and 512GB M.2 SSD drive it plays jerky. So if I have a 4K video camera still I have to buy an editor, new computer, a way to play the video on my TV without using a computer.

BebuLamar Your Laptop is not a woosy one, lots of kick! Try reinstalling the VLC after first uninstalling it. I had to play around to get a photo from 4K. See my comments in

This is a guess. Does your laptop have a 4K display? If not, the extra step of downscaling every frame or the way the player does it may be causing the issue. Don't know. I don't have any way to test this. Try another player if possible.

The laptop doesn't have 4K display. In fact it plays OK when downscaling to 1080p. I connect the laptop to the TV via HDMI and it plays in 4K but jerky.

I honestly don't know, but if I were having the same problem, I would:

1. Try a different HDMI cable.
2. Try a different TV.
3. Try a different playback player on the laptop.
4. If all failed, spend a lot of time googling the problem.

Maybe others have some other ideas.

You can edit for free using iMovie. Your phone might support your future 4K camera too. There are also some near broadcast quality video editors you can get for free on your future computer.

You can crop 4K video and still get better quality than if you shot with the same framing in 1080. You can film in 4K and have multiple camera angles from the same source. You can extract good quality stills of about 8mp. These can withstand some basic editing.

Video: When editing a show in 1080P, you can crop, apply software image stabilization (which is a variable crop), simulate a two-camera scene by cropping, and reap the benefits of sharper 1080P achievable only via downsampling.

4K video frames are 8.2 MP stills. 4K stills are, too. At 30 or 60 fps, you can do motion analysis, edit just the right moment, and more. 8.2 MP is more than enough for an 8x10 print.

Some mirrorless cameras run a continuous buffer of the last 15 frames or so, to improve the likelihood of capturing a scene at the right moment.

Sounds like the video processor could be the bottleneck culprit.

Look at a 4K video on youtube and pause it. Change the resolution to 1080P. You can see the added detail of video shot in 4K compared to 1080P, even though you are viewing on a 1080P monitor. Another advantage is in editing 4K video you can crop the frame more than you can on a 1080P video since you have 4x the resolution per frame.
As others have said, for the still photographer you can get better frames from video for still shots in 4K than in 1080P (2k). A frame grab from 4K is 8MP and from 1080P is about 2MP.

The advantage is to the actual image, not the version of the image you are viewing. Generally, the higher the color gamut and the higher the resolution, then the computer will recognize all of the pixels that were created. If you have a program that does not have all of the colors represented, then the program has to "guess" about the color of the pixel next to the one for which the computer does have a proper color. This ends up with some colors being out of gamut. If you are using PS, you can turn on the tool in the viewer that displays which pixels are out of gamut, and you will see which ones will not be accurately displayed.

When printed, the image will look funny.

I think so! It has the Intel video processor not an AMD or NVidia.
