What is 4K video editing

Question

Steve Grisetti and Bill each mentioned 4K editing, meaning I should consider this when buying a new computer. Or should I say, I should consider if I need/want to do 4K editing when I choose a new computer. Can someone tell me what 4K editing is? Especially as it relates to Adobe, since I am not doing any editing anyplace else.

Thanks.

Standard definition video -- the old TV standard -- was only 720x480 pixels in resolution. Only about 345,000 pixels or little dots of color making up each frame of video.

High Definition HDTV -- what most TVs are today -- is 1920x1080 pixels. That's about 2,000,000 pixels resolution or nearly 6 times the resolution of standard definition video. Because it is nearly 2,000 pixels wide, it is sometimes called 2K.

4K video is nearly 4,000 pixels wide -- 3840x2160 pixels. That's 4 times the resolution of high-def!

You can imagine how much more detailed that video would be! And some of the newer TVs are 4K rather than 2K.

But because it has 4 times the resolution, it can require a bit more computer power.

Most consumer camcorders and phones shoot in 1920x1080 HD. But some more advanced camcorders, phones and action cameras like the GoPro shoot in 4K. Though most likely you'll know if your device is shooting in 4K rather than HD.
