Almost everyone encounters many difficulties in downloading and storing large video files. Large videos are often associated with high resolution, you need to spend a lot of time and use high speed bandwidth to download them.
Do you know to reduce video size without losing quality, there are usually 2 ways to handle it:
- First : Shorten the video length , you can cut the beginning or end footage, or unnecessary places to reduce the file size.
- Second : Remove unnecessary audio from the video.
In addition to the above two ways, you can still use some application platforms to handle reducing the size without losing the inherent video quality, as follows:
- Processing by computer software : VLC (versions for Windows, Mac and Linux are available); Shotcut (available for Windows, Mac and Linux); and QuickTime Player (for Mac).
- Processing on online websites : VideoSmaller and Clipchamp.
The relationship between video size and quality
Before processing video, you need to better understand the 3 factors that affect video size : resolution, bitrate and encoding.
Resolution is the number of pixels represented in your video . It is usually represented by horizontal and vertical (horizontal x vertical) size numbers.
- For example, an HD video has a resolution of 1080p , usually denoted by the number 1920 x 1080 .
In addition, the common aspect ratio is 16:9 in addition to several other aspect ratios.
Here are the recommendations that YouTube provides to users to ensure the quality of uploaded videos:
So what resolution should you use?
This depends on the majority of people watching your video with what quality .
- For example, videos with 1080p quality are often chosen by users to watch the most on YouTube online, because of the beautiful and clear picture quality.
However, if viewers use their televisions to watch your videos on YouTube, then the higher the resolution, the better , but it still depends on the resolution of the TV screen . For example, with about 20% of Americans owning a 4K television in their home, the resolution of YouTube videos played on televisions is typically 1440p or 1080p .
In contrast, viewers using smartphones or tablets, to watch your videos are different. The video resolution displayed for viewing depends on the resolution, screen size and pixel density on the viewer’s device. Popular are 720p and 1080p video quality.
In addition to resolution, bitrate is also an important factor to help you handle video size. Bit rate represents the rate at which content information is transferred per second and is usually measured in units of Mpbs (or Kbps ).
Here are recommended YouTube video sizes and bitrates for users:
Therefore, if you want to change the size , you can affect the bitrate factor of the video according to the suggested numbers (in the table above). It is a good idea to allow the video size to increase or decrease depending on your purpose.
Video encoding consists of 2 elements: codec (decoder) and container r (complete file).
There is a lot of discussion about video encoding, but Thptlaihoa.edu.vn recommends usingH.264 encoding with MP4 encoder . This is an effective method of video compression , but it will slightly affect the quality
In fact, it proves that when you reduce the video size, it is almost inevitable to reduce the image display quality.
Understanding the 3 factors above (resolution, bit rate and encoding) that affect video size, will help you have a flexible way of handling when reducing file size while ensuring quality. optimal image display quality.
How to reduce video size and still retain quality
To reduce the video size while ensuring the best quality is preserved, you can use the following supporting platforms:

In general, you should choose the H.264 Baseline Profile format as the best choice. Because this format will help reduce the size of the video without reducing the quality of the displayed image too much.
Step 4 : Change the video resolution by adjusting the parameters in the section Resolution (resolution) and Aspect ratio (aspect ratio).
In addition, when you choose a lower output video quality than your original video, the resolution will also be reduced. This you can keep in mind when customizing the resolution so that it is reasonable.
QuickTime Player software
This is the default video processing software on Apple computers , including many great functions to help you manipulate more easily in video editing as well as experience many other entertainment features.

In conclusion, reducing video size while maintaining quality can be easily achieved by following these five simple steps. Firstly, choosing the right video format and codec can significantly decrease the file size without compromising quality. Secondly, adjusting the video resolution to an appropriate level can further optimize the video size. Thirdly, using efficient video compression techniques, such as bitrate adjustment and keyframe optimization, can further shrink the file size without noticeable degradation in quality. Fourthly, removing unnecessary audio tracks or using a lower audio bitrate can also help to reduce the overall video size. Lastly, utilizing video editing software or online tools specifically designed for video compression can make the process more effortless and yield better results. By implementing these strategies, users can enjoy smaller video files while still preserving the visual and auditory quality of their content.
