3D, HD, 1080p, 1080i, Blue-Ray, DVD … Everything you need to know about video

Part 1. Video quality

How do we celebrate the new year? That’s it, on the table! However, television is usually the most integral part of this table. New Years greetings, favorite shows, movies, shows, concerts, without this, the New Year would not be the holiday we are used to.

But the vacation itself lasts only one night, and there are many more vacations and weekends. And how else to decorate the cold days of the week in January that we spend at home, if not watching good movies in high quality? No way! What do we do when we want to see a movie? We turn on the TV … But there they impose a program on us, what if nothing relevant and interesting comes at the moment?

So a video player of any kind or a computer, in combination with the Internet or various discs, comes to our rescue. But, we already said that downloading from the internet is illegal. And time goes by, for example, you can’t download a 3D movie in such a modern format from the Internet. You’ll need a special monitor, special glasses, and for the sake of a movie, you really don’t want to pump out 30 gigabytes. What to do? And how do we understand what and how we see ourselves? How to get the most out of your film?

Or how not to spoil the impression of a canvas that has just been published, which has already been seen, but which you did not like at all due to the quality of the image? And it is not surprising, because this copy was filmed in an underground cinema, on a cheap video camera with shaking hands …

Everything can be solved! For the last time this year, I will open your eyes to the accessible, simple, but often hidden from the eyes of a normal man on the street!

Let go of ignorance. What is video quality?

Today, in 2012, already a year, let’s not mention the subject of videotapes. They have already outlived their own. Let’s see what video quality it is in general. What does it consist of? As measured? Various parameters:

Source. It is the most important. Without a high quality source you can do whatever you want with the video, record it wherever and however you want, it can’t be of better quality anymore. Worse please, but in the opposite direction, never. A simple example: take a movie from a DVD with 10 of them and burn it in Blue-Ray. Will the quality of this change? No…

Under the good quality source, or rather the one from which the countdown comes, we take the film edited in the film studio in the way it was assembled on the editing table in the final version. This is the source of all kinds of licenses and the video quality standard. Everything else can only be WORSE.

Resolution. No, not to see a movie! Video resolution measured in horizontal and vertical pixels. Have you often noticed that licensed DVD movies still look awfully “blurry” on modern “flat” TVs? And the television itself doesn’t look as “sharp” and “bright” as it used to? Many even complain that they bought expensive equipment, but everything has gotten even worse … And few people think that this process is roughly comparable to driving a Zaporozhets, buying a Mercedes, pumping gas from the first tank to the second tank and Undisguised surprise that this “gasoline” is enough for Mercedes for a very short time. Of course, Mercedes needs to fill its own full tank, not a full tank of Zaporozhets!

Do you remember the source? Therefore, it is already insufficient for comfortable viewing. Because standard television has a slightly worse transmission format than DVD. But even this is not enough for a clear display! So what kind of permissions are there?

480p: TV broadcast format. The letter p is responsible for the parameter of displaying the entire image at once, that is, at 24 frames per second, all the pixels in each frame are displayed. The resolution is 640×480 pixels (width x height ratio).

576p: widescreen DVD format, resolution 720X576.

720p – the youngest of the HD formats (high definition, high quality), most often used in games on modern XBOX360 and SONY PLAY STATION 3 consoles. Some modern TV channels also broadcast on it, so the picture looks a lot best. It has a resolution of 1024X768.

1080i: The format designated in technology as HD-Ready (not to be confused with Full-HD!). The letter i is responsible for the interlaced display method. That is, out of 24 (this is just an example, modern video has 60 frames per second), half of the frames will show all pixels across a line, in odd order, and the other half in even order. With this clever method, we have a high resolution, but in fact, although it is not noticeable with the naked eye, we get 12 frames per second, instead of 24. The resolution here is 1920X1080 pixels.
