Whether you're a video editing newbie or an experienced professional, there comes a time when you need to resize an MP4 video file. The reasons can vary: perhaps you need to upload the video to a social media platform like TikTok, with its unique vertical video requirements, or maybe you need to ensure the video fits a specific aspect ratio for a different project. Regardless of the reasoning, adjusting the video size or changing the pixel size is a crucial skill in today's digital age.

What is the Pixel Size and Video Resolution of an MP4?

Before we delve into how to resize an MP4, it's important to understand the concept of pixel size and video resolution. The resolution of a video refers to the number of distinct pixels that can be displayed in each dimension. Commonly, it is described in terms of width and height, for instance, a resolution of 1280x720 means the video contains 1280 pixels in width and 720 pixels in height.

The pixel size and video resolution are not specific to the MP4 video format; they apply to all video formats, including MOV, AVI, WMV, MKV, MPEG, and WEBM. It is worth noting that MP4 is a widely-used format due to its compatibility with many devices and platforms, as well as its high video quality at a relatively smaller video size.

Why Resize an MP4?

There are several reasons why one may need to resize an MP4. For instance, you might need to compress the video file to make it smaller for easier sharing or storage. Alternatively, changing the video resolution might be necessary to meet specific requirements for uploading on different platforms. Adjusting the aspect ratio ensures the video appears correctly on various screens, from widescreen monitors to compact smartphone displays.

How to Resize an MP4?

There are several methods available to resize an MP4 video, both offline and online. The process generally involves using a video editing tool or a video converter to change the video resolution, aspect ratio, or even the output format. Some tools also allow you to add subtitles, watermarks, and carry out other video editing tasks.
