Even though streaming movies and online shows are great, there is something to be said about having a physical copy with you for all sorts of occasions. Many people like to keep digital copies of their favourite films and TV shows, so that they can watch them anytime they want. However, the problem with video files is they are very large in size. Uncompressed video files of high quality can be more than 10 GB/minute. If you want to save video files efficiently, compression is a great idea.
If you are a novice when it comes to technology and computers, then you probably don’t know how to resize video files. Even though it can seem intimidating, compressing and resizing video is very easy. The most reliable and intuitive way to do it is by using an application called Wondershare UniConvertor. It is a fantastic file compression and conversion application that supports more than a thousand file types. Before you understand how video resizing works with the help of a step-by-step guide, here’s some more information on why you need it.
Factors That Affect the File Size and Compression of Videos
If you learn more about the factors that affect the file size and quality of video files, then you will be able to understand how to resize them properly. Here is an overview of the factors affecting video size.
1. Bitrate of the Video:
The bitrate is a technical term that describes the amount of information processed by the video file in unit time. As you can probably deduce from the statistic’s name, this information is measured in the number of bits per second. The file size of the video is directly related to its bitrate. You can actually calculate the file size of a video by obtaining the product of the bitrate and the video duration. The quality and definition of the video file in question is also directly proportional to the bitrate of the file.
2. Duration of the Video:
This is one of the most basic factors affecting the size of a video file. A 2-hours long movie will obviously have a bigger file size than a clip that is only 10 minutes long. This is why files with movies/documentaries are much larger than video files that have episodes/clips. The duration of the file also affects the amount of information contained in the file, in terms of images and audio. This is the reason why the video duration is given so much importance even though it is very rudimentary.
3. Codec of the Video:
While video uploaders and production houses upload films and TV shows for people to view, they use patches of software called a “codec”. A codec’s primary function is to encode and decode video simultaneously, according to its file format and the device it is being played on. The codec has a huge role to play in determining the size of the video file because the efficiency of the codec decides the bitrate of the video. Recently, many advanced codecs like the H-265 have been released that are exponentially more efficient than their vintage counterparts.
4. File Type of the Video:
One piece of information vital to the functioning and compression of a video file is its output type. There are more than a 1000 video file types that are available for usage. Some of them are proprietary while others are open source. Some of the most popular and widely-used file types include MKV, MP4 and AVI. Lossy and compressed file formats like MKV and MP4 are popular because they can preserve a high quality while being of a significantly smaller size. These file types can also be modified to include subtitles.
These are the basic factors that you should consider while you are resizing video files. You can enjoy the best results by settling on the right combination of bitrate, file type, duration, etc.
Here is a step-by-step guide that will help you to successfully resize and convert videos using the Wondershare UniConvertor. It is a popular and intuitive compression and conversion application that works with all kinds of devices.
Step 1: The first thing that you have to do is install the Wondershare UniConvertor program onto your device. Make sure you pick the version best suited to your system processor and your operating system. You will just have to download the file and install it properly.
Step 2: After you have installed the application onto your device, you need to launch it. On the main window, you have to switch to the tab that says “Video Compressor”. After you have switched to the compression tab, you have to click on the + icon to select video files.
Step 3: This will open a file explorer window where you will be able to browse and select the video files that you want to compress and resize. You can select multiple files this way. You can also drag and drop the video files directly into the conversion window of the application.
Step 4: The selected video file will be loaded into the application and you will be able to view all of the video specifications, such as bitrate, file type, duration, etc. You can customize all of these specifications accordingly. The “Preview” option will allow you to check your work beforehand.
Step 5: Click on the “File Location” tab and choose the destination folder for the compressed/resized video. Once this is done, all you have to do is click on the button that says “Compress”. When this button is clicked, the application will start the process of compression and conversion.
Once the process is complete, the application will save the compressed video file directly to your file destination. This is one of the easiest methods that you can use to resize all of your video files easily. All you need to do is download the Wondershare UniConvertor application onto your device and start resizing the desired files.
