These days it is easy to buy a good brand name 4TB drive for less than $100.Īnother issue with large size files is it takes longer to transmit them over the network. Fortunately, this problem can be easily fixed by purchasing a large external hard drive. If you have limited storage on the MacBook, then very big files can be a problem. And the same length video will be about twice larger as well. Besides, image quality twice more pixels also means twice more space. As a result, they produce the highest quality. If the image has fewer pixels, it means the image quality is lower.Ī resolution in 4K cameras is 3,840 × 2,160, or 8,294,400 pixels per image. Have you ever tried to zoom in a picture until it gets blurry? Well, the depth of how far you can zoom in depends on the number of pixels. In other words, the 1080p camera has a twice higher resolution. It sounds that 1080 is not much bigger than 720 however, the difference is quite big.Ī 720p camera has a resolution of 1,280 x 720 (921,600 pixels per image), and 1080p has a resolution of 1,920 × 1,080 (2,073,600 pixels per image). Since they can put cheap slow CPU into MacBook, Apple saves on non-essential parts such as webcam or audio.īut let’s compare 720p and 1080p cameras. While they don’t provide sales numbers, I remember reading somewhere that they sell iPhones with a 50% margin, i.e., they sell a phone that costs them $200 for $400.Īnd one way to increase margins is to buy cheap parts. Why did Apple not change it yet? I guess the reason is that the company likes big margins on its products. Apple had it on its laptops for 8 years, and eight years is a long time in the technology world. Let’s start with the fact that 720p cameras outdated.
