I see models not knowing the actual difference between 4K, FULL HD, and Semi-HD.
Cinema 4K = 4096 x 2160 (this may vary) = 4.27 times bigger than FULL HD
4K = 3840 x 2160 = 4 times bigger than FULL HD = 9 times bigger than Semi - HD
FULL HD (1080p) = 1920 x 1080 = 2.25 times bigger than Semi HD
Semi-HD = 1280 x 720
More pixels allow for more detail. So when making videos you should keep in mind that videos should be produced at minimum FULL HD. Why? If you go to BestBuy or other electronic stores 4K TVs are becoming the norm. Therefore the quality that one produces should be FULL HD at minimum since 4K is already 4 times bigger than FULL HD.

Recording 4K on Mac
If you read my past Blogs I have talked about recording videos using an iPhone. Since then Logitech has come out with the Brio.
The Logitech Brio is a 4K webcam!!! But if you have a Mac, how do you record 4K videos?
There are 2 important parts to this. The very first thing is making sure you record the video correctly, but then also editing and producing those videos so you don't lose the quality.
Here it is...
Recording
1. Open Quicktime Player.
2. File > New Movie Recording
3. Next to the record button is a v if you click that you can make sure the microphone and the webcam that you want are selected.
4. Then record.
Important Note: Make sure before you record that you have the right lighting. The better the lighting the better the quality of the video should appear. If you don't use the right lighting the video will look somewhat pixelated (what we call noise).
Post-Production: Personally, I use Premiere Pro for all my post-production. If you want to edit 4K video you need to make sure that your computer can handle doing it, but also that whatever software you use it should allow you to do 4K production. Things to look at while doing post-production are color quality, sharpness, and other similar things you would check in photos.
Important Note: 4K video file sizes will be MUCH larger. A video about 10 minutes done with color correction, etc etc in FULL HD can be 1.5GB where the same video in 4K can be 15GB. Also be prepared to let your computer sit for a few hours to do the post-production export.
