Change Video Resolution on Different Platforms

If you are looking for quick, simple ways to change the video resolution, you have come to the right place. In the article below, you will find some free tools that can help you change video resolution, without any video editing experience required. You can try MiniTool MovieMaker to change video resolution and convert video format on Windows computers, and use other tools to change video resolution on Mac computers and mobile devices.

Generally speaking, video resolution refers to the number of distinct pixels each dimension can display on digital devices. For example, when someone says a video’s resolution is 1024 by 768, that means it has 768 lines that are each 1024 pixels wide. Here is more background information about the video resolution. The most commonly seen types of video resolutions include the following:

Types of Video Resolutions

  • 4320p (7680×4320 pixels, it is also called 8K)
  • 2160p (3840×2160 pixels, it is also known as UHD video)
  • 1440p (2560×1440 pixels, it is commonly known as Quad HD resolution)
  • 1080p (1920×1080 pixels, it is abbreviated as Full HD or FHD)

720p HD resolution and SD (HD is short for Standard Definition. Usually the SD resolution is either 640 x 360 pixels or 640 × 480 pixels for video, and 720 × 480 and 720 × 576 pixels for regular DVD).

To get the best possible playback experience on different displays, you need to ensure both the video resolution and the aspect ratio are proper. For example, if you play the 720p (1280 x 720 pixels high definition) video on iPhone 6 Plus, you will meet the issue of black bars on the left and right sides of the screen. Changing video resolution ensures that you can avoid the black bars. The following are 5 good tools that you can try to change the video resolution on computers and iOS/Android phones.
