Change Video Resolution for Playback Smoothly on Any Devices

Sometimes you need to change the resolution for video files to be compatible with various devices. This article provides the best simple solution on this issue.


In order to change video resolution, first of all, let's take a brief look at the background. Video resolution is usually displayed as width x height, with the value given in pixels. For example, "1280x720" means the width is 1280 pixels and the height is 720 pixels.

3 Mainstream Types of Video Resolution Nowadays

 * Standard Definition (SD): The most popular standard resolutions are 640x360 and 720x480 for video, and 720x480 and 720x576 for DVD.

 * High Definition (HD): HD video refers to a resolution of 1280x720 (720P) or 1920x1080 (1080P, aka Full HD).

 * 4K (UHD): 4K video is a newly-emerging resolution standard for Ultra High Definition in 3840x2160 (2160P). With no doubt, it will become the mainstream standard in the near future.

Why Do You Need to Change Video Resolution?

In our daily life, it's easy for you to acquire some HD even 4K videos which are downloaded from web, recorded with camcorder or produced by nonlinear editing software. But you may have to change video resolution to cater to the different requirement for various devices. You know, some devices only support specific video resolution for normal playback. For better visual experience and compatibility, you are supposed to increase video resolution or reduce video resolution.

Increasing or upscaling video resolution, converting SD video to HD for example, refers to scale up the video image to fill a HD format (always with high resolution). It increases more pixels, but the quality will not improve. Meanwhile, the video size may become larger. So a poor original video file (e.g. 320P) is ALWAYS going to get bad result after you upscale video resolution to HD or 4K. Whatever other software you use, it MUST NOT reach your expected results. However, you might be satisfied with the final effect if you convert from 320P to 480P, 480P to 720P, 720P to 1080P, 1080P to 4K.

On the contrary, a huge demand also exists for reducing video resolution (aka downscale video resolution), such as downscale 4K to 1080P, 720P, 480P and so forth. Because the higher resolution means it need higher configuration to run and more space to store. That's the reason someone always wants to convert 4K to 1080P , 1080P to 720P.
