Greetings to all, it often happens that Windows cannot open a video file, or when it is played, only sound is heard, but there is no picture (most often, the player simply displays a black screen).
Usually this problem happens after reinstalling Windows (also when updating it), or when buying a new computer.
The video does not play on the computer due to the fact that the system does not have the required codec (each video file is encoded with its own codec, and if it is not on the computer, you will not be able to see the picture)! By the way, you hear the sound (usually) because the OS Windows already has the necessary codec to recognize it (for example, MP3).
Logically, in order to fix this, there are two ways: installing codecs, or a video player in which these codecs are already embedded. Let's talk about each of the methods.
Installing codecs: what to choose and how to install (typical questions)
Now on the network you can find dozens (if not hundreds) of different codecs, sets (sets) of codecs from different manufacturers. Very often, in addition to installing the codecs themselves, various advertising add-ons are installed in your OS Windows (which is not good).
I recommend using the following codecs (during installation, however, pay attention to the checkboxes): https://pcpro100.info/luchshie-kodeki-dlya-video-i-audio-na-windows-7-8/
In my opinion, one of the best sets of codecs for a computer is the K-Lite Codec Pack (the very first codec, from the link above). Below in the article, I want to consider how to install it correctly (so that all videos on the computer are played and edited).
Correct installation of the K-Lite Codec Pack
On the page of the official site (and I recommend downloading codecs from it, and not from torrent trackers), several versions of codecs (standart, basic, etc.) will be presented. You must select the complete (Mega) set.

Next, you need to select the mirror link, by which you will download the set (the file is downloaded well for users from Russia through the second 'mirror').

It is important to install all the codecs that are in the downloaded set. Not all users check the boxes in the right places, therefore, even after installing such sets, their video does not play. And all is simply due to the fact that they did not tick the boxes opposite the required codecs!
A few screenshots to make everything clear. First, select the advanced mode during installation so that you can control each step of the program (Advanced mode).

I recommend choosing this option during installation: 'Lots of sruff' (see Fig. 4). It is in this option that the largest number of codecs is installed in automatic mode. You will definitely have all the most common ones, and you can easily open the video.

It will not be superfluous to also agree to associate video files with one of the best and fastest players – Media Player classic.

In the next step of the installation, you will be able to select which files to associate (i.e. open by clicking on them) in Media Player Classic.

Choosing a video player with built-in codecs
Another interesting option for solving the problem when the video does not play on the computer is to install the KMP Player (link below). The most interesting point is that you don't have to install codecs in your system for it to work: all the most common ones come with this player!
I have a blog post (not so long ago) with popular players that work without codecs (i.e. all the necessary codecs are already in them). Here, you can familiarize yourself (the link will find, among other things, the KMP Player): https://pcpro100.info/proigryivateli-video-bez-kodekov/
The note will be useful to those who did not suit KMP Player for one reason or another.
The installation process itself is standard, but just in case I will give a few screenshots of its installation and settings.
First, download the executable file and run it. Next, select the settings and type of installation (see Fig. 7).

The location where the program is installed. By the way, it will require about 100MB.

After installation, the program will automatically start.

If suddenly, the files do not automatically open in KMP Player, then right-click on the video file and click properties. Next, in the 'application' column, click on the 'edit' button (see Fig. 10).

Select the KMP Player program.

Now all video files of this type will automatically open in the KMP Player program. And this, in turn, means that you can now watch the absolute majority of films and videos downloaded from the Internet (and not only from there :))
That's all. Happy viewing!
