Freezes video on the computer, what should I do?

lags-video-on-computer Hello.

One of the most popular tasks on a computer is playing media files (audio, video, etc.). And it is not uncommon when, when watching a video, the computer starts to slow down: the image in the player jerks, jerks, the sound may start to 'stutter' – in general, it is simply impossible to watch a video (for example, a movie) in this case …

In this short article, I wanted to collect all the main reasons why video slows down on a computer + their solution. After following these recommendations, the brakes should disappear altogether (or, at least, they will become noticeably smaller).

By the way, if your online video slows down, I recommend that you read this article:


1) A few words about video quality

Many video formats are now widespread on the network: AVI, MPEG, WMV, etc., and the quality of the video itself can be quite varied, for example, 720p (video picture size 1280 × 720) or 1080p (1920 × 1080). So, the quality of playback and the degree of computer load when watching a video is influenced by two main points: the quality of the video and the codec with which it was compressed.

For example, to play 1080p video, as opposed to 720p, you need a computer 1.5-2 times more powerful in performance (- for comfortable playback). Moreover, not every dual-core processor will be able to pull video in this quality.

Tip # 1: if your PC is already hopelessly outdated, then you cannot make it play a high-quality video file in high resolution, compressed with a new codec, with any settings. The easiest option is to download the same video on the Internet in a lower quality.

2) Loading the processor by extraneous tasks

The most common cause of video stuttering is CPU utilization by various tasks. Well, for example, you install a program and decide to watch a movie at this time. They turned it on – and the brakes began …

First, you need to start the task manager and see the processor load. To start in Windows 7 / 8, press the key combination CTRL + ALT + DEL or CTRL + SHIFT + ESC.

Booting the computer - Task Manager Windows 7.

CPU load 8% -Task manager Windows 7.

Tip # 2: if there are applications that load the CPU (central processing unit) and the video starts to slow down, disable them. Especially it is worth paying attention to tasks that use the CPU by more than 10%.

3) Drivers

Before you start configuring codecs and video players, you should definitely understand the drivers. The fact is that a video card driver, for example, has a serious impact on the video being played. Therefore, I recommend, in the case of similar problems with a PC, always start with the drivers.

To automatically check for driver updates, you can use the special. programs. In order not to repeat about them, I will give a link to the article:

1-DriverPack Solution 14 searches for drivers

Updating drivers in DriverPack Solution.

Tip # 3: I recommend using Driver Pack Solution or Slim Drivers to check your entire PC for the latest drivers. If necessary, update the drivers, restart the PC and try to open the video file. If the brakes have not passed, go to the main thing – the settings of the player and codecs.

4) Video player and codecs – 90% of the reason for video brakes!

This title is not accidental; codecs and a video player play a huge role in video playback. The fact is that all programs are written according to different algorithms in different programming languages, each player uses its own image rendering methods, filters, etc. Naturally, the consumed PC resources for each program will be different.

Those. two different players working with different codecs and playing the same file – they can play completely differently, one will slow down, and the other will not!

Below, I want to offer you several options for installing players and configuring them in order to try to reproduce problem files on your PC.

Important! Before you start configuring the players, you must completely remove from Windows all codecs that you had previously installed.

Option number 1

Media Player Classic


2015-03-08 10_04_20-Media Player Classic Home Cinema

One of the best players for video files. When you install it, the system will also install the codecs required to play all popular video formats.

After installation, start the player and go to the settings: menu 'view' -> 'Settings'.

Further in the column on the left you need to go to the section 'Playback' -> 'Output'. Here we are interested in the DirectShow Video tab. There are several modes in this tab, you need to select Sync Render.

Next, save the settings and try to open the file in this player. Very often, after doing such a simple setting, the video stops slowing down!

If you do not have such a mode (Sync Render) or it did not help you, try the others one by one. This is how the tab has a very serious impact on video playback!

Option number 2

2015-03-08 10_24_23-VLC Media Player

The best player to play online videos. Plus, this player is fast enough and uses less CPU than other players. That is why video playback in it is very much better than in many others!

By the way, if your video in SopCast slows down, then VLC is very useful there too:

It should also be noted that VLC media player in its work uses all the multithreading capabilities to work with H.264. For this, there is the CoreAVC codec, which is used by the VLC media player (by the way, thanks to this codec, you can play HD video even on weak computers by modern standards).

Before launching a video in it, I recommend going to the program settings and enabling frame skipping (this will help to avoid delays and jerks during playback). Moreover, you will not be able to notice by eye: 22 frames or 24 are shown by the player.

Go to the 'Tools' -> 'Settings' section (you can just press the CTRL + P combination).

Next, enable the display of all settings (at the bottom of the window, see the brown arrow in the screenshot below), and then go to the 'Video' section. Here check the boxes next to 'Skip late frames' and 'Skip frames'. Save the settings, and then try to open videos that were slowing down before. Quite often, after such a procedure, the videos begin to play normally.

Option number 3

Try players that contain all the necessary codecs (i.e., the codecs that are installed on your system are not used). Firstly, their built-in codecs are optimized to work best in this particular player. Secondly, the built-in codecs, at times, show better results when playing video than those built into the various collections of codecs.

An article about such players:


If the above measures did not help you, you need to do the following:

1) Scan your computer for viruses –

2) Carry out optimization and cleanup of garbage in Windows –

3) Clean the computer from dust, check the heating temperature of the processor, hard drive –

That's all. I would be grateful for the additions to the material, how did you speed up the video playback?

All the best.
