What to look for when converting video?

Often the need for video converting arises when storing video captured by a camcorder. The hard drive is not spaceless, to allocate hundreds of gigabytes for video is not always possible. Someone, on the contrary, spares no space for the video, but the phone’s flash drive is not dimensionless, and you might want to watch the series on the road.

This is where video converter programs come to the rescue, which can convert video files so that they take up less space. They have some specific advantages, but, unfortunately, theydon’t allow you to quickly convert videos to those who have never encountered this. In addition, the devices are different, each needs its own format.

Simply put, video converting is the transformation from one format to another with the ability to change its quality, picture resolution, bit rate, sound quality and aspect ratio.

How and why to convert video from YouTube?

Surely you have a couple of videos that you would like to share not only with loved ones. Why not go ahead and upload the video to the network – namely on YouTube? The most popular channels can have millions of views and subscribers. But they all started with something small. Therefore, rather decide on the theme of your channel and go – shoot!

When you have shot the material and mounted the video, it’s time to upload it to the network. However, here you may expect a small problem: YouTube does not support the format of your file.

YouTube favors a small list of formats: MP4, AVI, WMV, MOV, 3GP, FLV, MPEG-1,2 and WebM. And the perfect combination would be the MP4 format with the H.264 video codec and AAC audio codec. Such settings give high quality video and a relatively small size.

Here you will find a convenient online tool for converting youtube video to mp3. This may be useful if you want to save sound from an audiobook, song, or video tutorial. Thus, you can significantly save space on your hard drive.

Below in this article we will tell you what characteristics exist in video files and what should be considered when converting.

Let’s talk a little about the most popular formats

  1. MPEG is one of the main file compression standards. It stands for Moving Pictures Expert Group (the name of the organization involved in its development). It has four varieties: MPEG-1, MPEG-2, MPEG-3, MPEG-4.
  2. AVI (Audio-Video Interleaved) is a very popular format, more precisely – a container. It was developed by Microsoft. Four types of data can be stored in such a container – audio, video, text, and midi. It can include videos of any format, starting with MPEG-1 and ending with MPEG-4, sounds of various formats; a combination of codecs can be anything.
  3. WMV (Windows Media Video) is another format from Microsoft. If you create a video in Movie Maker, which comes with Windows, it will have this format.
  4. Mov. This format was invented by Apple. In addition to video data, it can contain graphics, animation and 3D. Files of this format are played in Apple’s QuickTime Player.
  5. HD (High Definition) – a high-resolution format used for high definition images. Currently, has two varieties of a resolution: of 1280 × 720 and 1920 × 1080, both are designed for a frame with an aspect ratio of 16: 9 and a square pixel.

More about video files

Compressing videos by archivers, like ordinary documents, will not work. WinRar, 7-zip and others like them are useless. You need to use special video converter programs. They are also called “encoders.”

To explain what the encoding has to do with it, you need to understand what a video file is. Open the “Properties” of one of them.

Each video file is a container with encoded information. In this case, the video and audio information is encoded in the file.

Depending on the container, several “tracks” with video and sound can be present in one file at once, between which you can switch when viewing. We just want to convert the video, so in this case, we don’t need such details. We will manage only the basic properties of the video.

What properties does the video file have?

The width and height of the frame are important characteristics (they are also called resolution). Lower resolution means less image and worse quality.

When watching a video of small resolution on a large screen, the picture will stretch and become cloudy.

Please note that small labels are difficult to read. Therefore, the higher the resolution, the better.

It makes no sense to set the image size larger than the one that was originally – this will not add quality, the video size will increase.

The aspect ratio of the image width to height is a property that many people forget. It is very important to observe proportions. If you shot a video on a phone that records in a resolution of 1280 by 720 pixels, do not be surprised that in a resolution of 640 × 480 (some old TV set-top players can only play such a video) the picture will be flattened on the sides. The thing is that the ratio between the height of the frame and the width has been violated.


On YouTube, you can see many examples of how people forget about proportions (aspect ratio) and get a stretched or, conversely, compressed video:

Most video converting programs have a checkmark that allows you to trim the video or add black bars around the edges to avoid such problems.

Bitrate (video stream speed) – a parameter that is responsible for the size of the video. The higher the bitrate, the larger the file size. The lower the bitrate, the smaller the file. Roughly speaking, the bitrate determines how many bytes to allocate for each frame. Here’s what happens if you make the bitrate too low.

“Which bitrate to choose?” – you ask. Unfortunately, there is no exact answer. For the best result, they are selected empirically so that the result does not look much worse than the original.

Fortunately, there is a way to lower the bitrate and get a smaller file, while not losing much in the quality of the video. You just need to choose the right codec.

Video codec is a way of storing video in a file. Codecs are different. Some allow you to quickly save video without load on the processor, while creating files of gigantic size (this is what programs for recording video from the screen, such as Fraps), others allow you to store files as compactly as possible, but take time to process.

The quality and size of the video file depend on the right choice of codec.

How to Avoid Errors When Converting Video Files? Explanation for Beginners

Converting a video is the changing of its format. You may need this procedure when uploading or downloading videos on your computer. Learn what to pay attention to before converting.

Video convertingis often needed in many cases when there is a conflict of formats. Since each video file has a number of features, it is not always possible for beginners to correctly convert it.

The most common converting problems:

  • loss of image quality;
  • aspect ratio distortion.

There is a huge variety of software converters. Take the time to figure them out and you can convert video files of any format.
