Yes, you can change the size of a video using video editing software or online tools. Changing the size of a video typically involves altering its resolution, which is the number of pixels displayed horizontally and vertically. This process is often referred to as resizing, scaling, or resampling.
There are two main ways to change the size of a video:
Downscaling: This involves reducing the resolution of a video, which can lead to a smaller file size and make the video more suitable for playback on devices with lower screen resolutions or limited bandwidth. Downscaling a video can also help you meet the resolution requirements of specific platforms. However, reducing the resolution may result in losing detail and overall video quality.
Upscaling: This is the process of increasing the resolution of a video. Upscaling can help improve the appearance of a low-resolution video when viewed on a high-resolution display or when meeting the resolution requirements of a particular platform. However, it's important to note that upscaling does not add more detail to the original video; it merely interpolates the existing pixel data to create a larger image. As a result, upscaling can sometimes lead to decreased perceived video quality, with the output appearing blurry or pixelated.
To change the size of a video, you can use video editing software such as PowerDirector.
When resizing a video, always consider the aspect ratio, which is the relationship between the width and height of the video. Maintaining the original aspect ratio during resizing ensures that the video does not appear stretched or distorted.
