How to Compress a Video


When a video file takes up too much space on the computer, it becomes necessary to compress it, and it is desirable that how to compress a video without losing its quality.

If you like to watch movies on your player, tablet or mobile phone, you can’t do without video compression.

As a rule, the capacity of memory cards of portable devices is very limited, and these devices themselves only support video of a certain format and with certain characteristics.

It happens that the video is played on a mobile device without preliminary preparation, but often the playback quality leaves much to be desired: the video is played irregularly, “slows down” and “freezes”.

To upload a video to the Internet, in many cases it also needs to be prepared and compressed in a special way.

Usually there are a lot of difficulties in this process: you need to choose the right format suitable for online broadcasting, for example, FLV or MP4, in addition, the video should be relatively small in size so that even users with a low Internet connection speed can watch it.

The desire to compress the HD 1080p media file as much as possible while maintaining high image quality and reducing “weight” has given rise to many programs for compressing video files.

Let’s see how to compress a video in the two most popular applications. The process consists of several simple steps and does not require specific knowledge from you.


How to Compress a Video with VideoMaster

Adding a video file

To know how to compress a video with VideoMaster program, install it on a computer.

In the window that opens, a prompt will appear with a brief sequence of actions. Pay attention to the laconic design and convenient location of all function keys.



You should click the “Add” button to select or download video for conversion using one of the proposed methods.

Specify the path to the file that requires conversion, and click the “Open” button. The image of your video will be added to the application menu.


Convert and compress video

The type of conversion format affects the quality, volume and its compatibility with various devices.

The conversion format is selected in two ways: using the icon button located to the right of the name of the selected source, or in the “Convert to format” drop-down list located on the lower control panel.

You will immediately find lines for conversion in popular video formats: mp4, avi, wmv, mpeg, mkv, etc.


Fine tuning

In addition to the format, you can choose a file compression method, models of smartphones, game consoles, players, or formats of one of 12 popular web resources.

The selected options apply to all files if you select the “Apply for all” box. The video resolution and other settings of the output file are automatically adjusted to the most optimal parameters recommended by the device manufacturer / site developers.


Extra options

In our case, the settings selected by the program are considered optimal for maximum compression without losing high quality in the mp4 file format, but additional opportunities have been prepared for experiment lovers: choose a codec, container, format, and change the frame rate.

Highlighting one of the selected files and clicking the “Duplicate” button you will get a copy of the source, taking into account high resolution.



Experiments are carried out using tools such as: removing an additional audio track, trimming the beginning or end of a video clip, as well as controlling other subtle parameters of the video, processing some fragments, etc.

Correct settings will reduce the size of the video file several times without loss of quality. Visually, the difference will not be felt.


Folder selection

The folder to save is selected in the lower control panel. We recommend that you choose the outgoing directory not on the system partition, also ignore disks on which there is no space and remember that the encoding buffer is large.

Even if you want to receive video on your phone, leave at least 3 times more free megabytes on drive C than the original record had. If everything is ready, you can start the process of reducing the size – click the “Convert” button


Conversion and Shutdown

It will take from a few minutes to a couple of three hours, depending on the type / size of the source and the options selected. The process can be paused, interrupted, completed by turning off the device or uploading material to a channel on YouTube or another popular website – Facebook etc.
