How Do I Resize a MP4 Video Without Losing Quality?

Do you have a large MP4 video that needs to be resized for a specific purpose? Perhaps you want to upload it to a website, send it via email, or play it on your mobile device.

Whatever the reason may be, resizing an MP4 video without losing quality can be tricky. But don’t worry, with the right tools and techniques, it can be done effectively.

Why Resize an MP4 Video?

Before we get into the specifics of how to resize an MP4 video, let’s first look at why resizing may be necessary.

One of the main reasons for resizing an MP4 video is to reduce its file size. This is important when you need to transfer or upload the video quickly and easily. Large files can take up a lot of storage space and may also take longer to download or upload.

Another reason for resizing is when you need to fit the video into a specific frame or screen size. For instance, if you’re creating a video for social media platforms like Instagram or TikTok, the video needs to fit within their specified dimensions.

Methods of Resizing an MP4 Video

There are several methods you can use to resize an MP4 video without losing quality.

Method 1: Use Online Tools

One of the easiest ways to resize an MP4 video is by using online tools such as Clideo or Kapwing. These tools are free and don’t require any software installation.

To use these tools, simply upload your MP4 file and select the desired output size. The tool will automatically adjust the resolution and compress the file while maintaining its quality. Once done, you can download the resized file directly from the website.

Method 2: Use Video Editing Software

Another way to resize an MP4 video is by using dedicated video editing software such as Adobe Premiere Pro or Final Cut Pro. These software programs offer more advanced editing features and allow for greater control over the resizing process.

To resize a video using video editing software, import the MP4 file into the program and create a new sequence with the desired output size. Then, drag and drop the original video onto the timeline and adjust its size to fit within the new sequence. Once done, export the resized video in MP4 format.

Method 3: Use FFmpeg Command Line Tool

For those who are comfortable with using command line tools, FFmpeg is a powerful open-source tool that can be used to resize an MP4 video without losing quality. However, this method requires some technical knowledge and may not be suitable for everyone.

To use FFmpeg, first download and install it on your computer. Then, open a command prompt or terminal window and navigate to the directory where your MP4 file is located. Next, enter the following command:

ffmpeg -i input.mp4 -vf scale=1920:1080 output.mp4

This command will resize your MP4 video to 1920×1080 resolution without losing quality. You can adjust the output size as needed.
