Android P Users: Meet VP9 and HEIF with New Additions

We’ve heard of Android P for a while now and we know that it’s not just a change on how you use your phone. It has lots of features that can make your life easier in the time you’re using it. We’re talking about two specific additions. It’s known that they’re going to be dependent on the hardware, but there’s no doubt in saying that a leader phone from Android will support these two. They’re definitely going to change some stuff since they will have a great influence on your creation and use of your media.

We’ll get HEIF

HEIF stands for High-Efficiency File Format, and it shows a modern way to compress images.

We’re sure you already know that there are some files, like bitmaps (the .bmp files) that are larger than the other types of files, like .jpg. It all happens because of the compression. You are able to compress any file that you want, and that is for how many times you want.

How does it happen?

There’s an algorithm that searches among all the data of the file and it does different commands,  such as erasing duplicate data, use rounding in order to make comparable colored pixels to the same color and to lower the depth of the color. It’s amazing how it can have a very large file, let’s say a 50MB, tiff. file and compress it to 2MB, in the form of a .jpg file. This feature is really going to do a great job.

The photos will be the same, just smaller files

It’s a known fact that the human eye can see millions of colors, but we don’t really know all the shades. And we also understand that our display, the one we use to see the photos on, doesn’t really provide all the data of the photos. Files can be cut to some million colors for the best quality but those eight colors are really bad. It’s not possible that your phone has the 8-color display, it doesn’t really matter who did it – phones have the 24-bit display (the one which is also known as True color and can show 16 million colors). There’s a high chance that your phone will save the images as 16-bit .jpg or as 24-bit .jpg. You cannot know what or how much of the data has been taken away.

 

You’re already familiar with VP9

Google has developed a coding format program called VP9. You may not know it yet, but if you’ve already used Chrome or Android, you’ve surely seen VP9 videos without even knowing.
