Video does not play on the computer: what to do?

VLC Media Player

This popular media player can, among other things, fix damaged videos.

First, let's just try to open the damaged video file in VLC. The player will display an error message.

Click on “Build Index, Then Lose.” Building an index of a video file can take a lot of time. But in most cases, these actions are enough - the file will open.

If you have a lot of damaged video files and you don’t want to open them one by one, go to the player settings and in the “Input / Codecs” section, select “Fix if necessary.”

Please note that VLC does not fix your file, but creates a temporary corrected copy of it, which disappears after playback is complete. If you try to open the file in another player, it will not be able to play. To make a corrected copy of a damaged file, select “Media” → “Save or Convert” from the menu and convert the file to another format. Or the same one.

How to open MP4

One of the popular video formats is MP4. Let's find out which programs can be used to play files with the specified extension on a computer.

Programs for playing MP4

Considering that MP4 is a video format, it is safe to say that most multimedia players will be able to play this type of content. In addition, some file viewers, as well as other types of applications, can cope with the task. We will consider in detail the instructions for opening objects with the specified extension in specific programs.

Method 1: MPC

Let's start with a description of the algorithm for activating the playback of MP4 videos from the popular MPC multimedia content player.

1. Launch your media player. Click “File” and then select “Quickly open a file...”.
2. A window for opening a multimedia file appears. Go to the MP4 placement directory there. With this object selected, apply “Open”.
3. The player will start playing the video.

Method 2: KMPlayer

Now let's look at how you can open MP4 using KMPlayer, which is one of the most functional media players.

1. Activate KMPlayer. Click on the player symbol and select "Open file(s)".
2. A window for opening a multimedia file opens. Open the MP4 hosting directory. After marking the object, use “Open”.
3. Playing the video file in KMPlayer has started.

Method 3: VLC player

The next player, the algorithm of which will be discussed, is called VLC.

1. Launch VLC player. Click "Media" in the menu, and then click "Open File...".
2. A typical media file selection window appears. Open the MP4 clip location area. After making a selection, click “Open”.
3. Playback will start.

Method 4: Light Alloy

Next, we will look at the procedure in the popular media player Light Alloy.

1. Open Light Alloy. This program does not have the familiar “File” menu. Therefore, you will have to perform actions using a slightly different algorithm. At the bottom of the window there are media player controls. Click on the one located on the left edge. This element is called “Open file” and looks like a button containing a triangle with a line under the base.
2. After this, a tool already familiar to us will launch - the opening window. Go to the directory where MP4 is located. Once you have selected it, click “Open”.
3. Playback of the video will begin immediately.

Method 5: GOM Player

Let's study the algorithm for launching a video of the required format in the GOM Player program.

1. Click on the application logo. On the menu o.
2. The selection window is activated. Open the MP4 hosting area. After marking the item, click “Open”.
3. You can enjoy watching the video in GOM Player.

Method 6: jetAudio

Although jetAudio is primarily designed for playing audio files, you can easily watch MP4 videos with it.

1. Launch jetAudio. Click on the “Show Media Center” button, which is the very first one in the block of four elements. This action enables the player mode in the program.
2. Next, right-click on the empty space on the right side of the program. A menu appears. Go to the name “Add Files” and select a completely similar name in the additional list.
3. The selection window opens. Open the location area of ​​the target media file. With it selected, use "Open".
4. The selected item will appear in the JetAudio playlist. To start playing, double-click on it with the left mouse button (LMB).
5. MP4 playback in JetAudio has started.

Method 7: Opera

This may seem surprising to some users, but MP4 files located on a computer can be opened using most modern browsers, for example, using Opera.

1. Activate Opera. Considering that this browser does not have graphical controls that can be used to launch a file opening window, you will have to act using “hot” buttons. Use the combination Ctrl+O.
2. The opening window appears. Open the MP4 location folder. After marking the file, select “Open”.
3. Content playback will begin directly in the Opera shell.

Of course, if you don’t have a full-fledged media player at hand or don’t want to launch it to briefly familiarize yourself with the contents of a video file, then Opera is quite suitable for playing MP4. But you need to take into account that the quality of display of material and the ability to control it in the browser is significantly lower than in the video player.

Method 8: XnView

Another type of program that can play MP4 videos is file viewers. This feature is available in the XnView viewer, which, oddly enough, specializes in viewing images.

1. Launch XnView. Click "File" and select "Open...".
2. A selection window opens. Enter the folder where the video is located. Once you select the file, use “Open”.
3. The video file will start playing.

It is worth considering that with this viewer, like browsers, the quality of MP4 playback and the ability to manage video will be noticeably inferior to those of full-fledged players.

Method 9: Universal Viewer

Another viewer that can run MP4, unlike the previous program, is universal and does not specialize in playing a specific type of content. It's called Universal Viewer.

1. Open Universal Viewer. Click on the “File” item. Select "Open...".
2. The opening window opens. Using its capabilities, open the directory where the desired video is located. Once you've marked it, use "Open."
3. The content will start playing.

Like the two previous methods, this program also does not have as many functional capabilities for working with the MP4 format.

Method 10: Windows Media Player

The Windows operating system also has its own player, which is designed for playing MP4 - Media Player. When using this method, you do not need to install additional software.

1. Launch Media Player.
2. Here, like Opera, there are certain features associated with opening a file. This program also does not have graphical elements for launching a file. Therefore, the video will have to be dragged into the application shell. Open Explorer and LMB-click the video to the area labeled “Drag items here” in the Media Player window.
3. Content playback is activated in the shell of the built-in player of the Windows operating system.

There is a fairly large list of media players that support playback of the MP4 video format. We can say that almost any modern representative of this type of program can do this. They, of course, differ from each other in functionality and processing capabilities of running content, but in terms of playback quality, the difference between them is minimal. Windows also has its own built-in player - Media Player, which can also work with files of the specified extension. Therefore, it is not at all necessary to install third-party programs to view them.

In addition, objects of the specified format can be viewed using a number of browsers and file viewers, but they are still inferior to multimedia players in terms of the level of output images. So they are recommended to be used only for superficial acquaintance with the content, and not for full viewing.

We are glad that we were able to help you solve the problem. Ask your question in the comments, describing the essence of the problem in detail. Our specialists will try to answer as quickly as possible.

Restore.Media

Recovery technology is built around searching for all file fragments available on the media, as well as restoring individual micro-sections in its structure based on available information. This method allows you to revive damaged videos, but not always completely - it is possible that a heavily damaged document will lose sound or picture at some points.

How to work with the program: the resuscitator works online in automatic mode. To access the recovery menu you need to complete a short registration.

What formats does it support: the service works with mp4, mov, mv4, m4a, qt, 3gp, video codecs AVC / H.264 and HEVC / H.265, audio AAC, ADPCM, PCM, MP3 and AMR. A manual MXF recovery service is available separately; to obtain this service, you must contact the site’s technical support.

The cost of file recovery depends on its size, video recording duration and format; it is calculated individually for each downloaded document.

Damage to codecs

Even if you have the necessary codecs for video decoding, problems may appear. Typically, damaged codecs cause the following problems: lack of sound or image, appearance of image defects, slow or fast video playback on the computer.

To understand that the cause of your problem is damaged codecs, it’s worth doing a little fraud. You need to play several videos of the same format, where some will use the same codec as the file with which the error occurred, and some will use a different codec. You can also try playing a file of a different format. If other video files play, then the problem is in the codecs.

How to solve this problem?

If you have this problem, you need to remove your codecs through the “Control Panel” and “Uninstall Programs”. Next, you should download a new codec package.

You can also resolve problems with codecs by reinstalling Windows Media Player. This can be done through the official Microsoft website or using certain sites.

Combining codecs on one PC

, the problem of combining different codecs on one PC may arise A huge number of codecs sooner or later lead to problems with playing video and audio files.

This happens because different codecs may not play well with other codec versions. In this regard, they do not replace each other and can be, in principle, the same, but from different developers.

What to do?

First you need to remove all codec packages from your PC:

1. We go to “Start”.
2. Next, find “Control Panel”.
3. Open “Uninstall programs”.
4. There you will see codec packs. We delete from there everything that can be deleted through the selection and the “ Delete” button.

After removing the codecs, we restart the computer and play the video. Usually after this the problem is automatically fixed.

Damage to the video file itself

Video corruption is the simplest cause of the problem. It happens that when downloading a file from the Internet or from a flash card, the file becomes damaged. This occurs because some bits of the file are lost when downloaded.

Also, the file may be partially damaged, that is, there will be no video or audio. In addition, it is possible that some parts of the video file are missing. In any case, file damage will be immediately visible.

What to do?

First you need to understand: is the problem only with this video file or with others too? Play a couple of other videos on your computer and if there are no problems with them, then the file itself is damaged.

Solving this problem is quite simple - you need to find this video in a different format. Or find another source to download it.

Why doesn't the video open and what should I do?

Some of these formats open in the operating system by default and we don’t notice it, because when everything is fine we don’t pay attention. But some formats cannot be opened on a computer without additional programs. Because when they were recorded, they were sort of encoded into a certain format that our operating system does not understand.

In order for the computer to understand that there is a video in front of it, it is necessary to decode it. In order to decode the video, codecs are needed that will cope with this task perfectly.

In our case, codecs are a program that converts data into a data stream that is understandable for our operating system and thus allows you to play video in a certain format.

So that you are no longer bothered by the situation when some video on your computer does not want to open. There are several important steps to take. The simplest thing is to install a set of high-quality codecs, which in a few minutes will help your operating system open any known formats. (There are exceptions, but very rarely)

I tried to save your time and have already uploaded a set of excellent codecs to my website, all you have to do is download them and install them on your computer.

Download codecs for opening videos, free: download right now

Also, in some cases, users prefer, in addition to installing codecs, to find a comfortable video player that can also decode most known video formats. For this, they usually use VLC Media Player or Media Player Classic, and many people prefer KMP Player, I also like it, but it’s annoying with unnecessary advertising. But we will talk about choosing a player in the next article.

Lack of video card drivers

If the three methods did not help and the video does not play on your computer, then it is likely that the video card driver is not working correctly or is missing altogether. You are unlikely to notice problems on your desktop until you encounter a video file playing.

Open Device Manager in Start, then in the Video Adapters section, find the name of your video card. If there is no question mark next to the name, which indicates a problem in the system, then everything is fine with the driver.

Otherwise, go to the hardware manufacturer's website and download the latest drivers for your video card, or simply find the driver disk that came with your video card.

Install the drivers.
After restarting the computer, the problem with playing video files should stop. We hope that in this article you found the answer to the question “Why the video does not play on the computer.” Share.
