How to Change Video Resolution

Edited by Pat Bitton

October 2, 2019

Video resolution is usually expressed as width × height, with the value given in pixels. There are two types of video resolution: Standard Definition (SD) and High Definition (HD). The most popular standard resolutions are 640 x 360 and 640 × 480 for video, and 720 × 480 and 720 × 576 for DVD. HD video usually has a resolution of 1280 × 720 (720p) or 1920 × 1080 (1080p, also called Full HD).

There are different situations in which you may need to change video resolution. It’s not hard to reduce the resolution of a video. But if you want to increase it, keep in mind that the quality will not get any better, while the video size may grow. These transformations may be necessary only in rare cases.

Here are a few problems that can be solved by changing the video resolution.

Can’t open a video on your device?

If you want to upload a high-resolution video to your mobile device, you may need to reduce the video resolution, since these devices often support only specific resolutions. Movavi Video Converter has special presets for iPhone, Samsung, Huawei, and other popular mobile devices.

Want to upload a video to a website?

A lot of websites have limitations regarding video resolution. So, if you want to upload your video to a particular website, there’s a chance you’ll need to change the resolution of the video file.

Need to burn a video to DVD?

If you want to burn a low-resolution video (for example a 320 × 240 video shot on your cell phone) to DVD, you will need to increase the resolution because the DVD standard requires video to have a resolution of no less than 720 × 480.

You can change video resolution using a desktop app or an online tool.

Add Video to the Program

Run Movavi Video Converter and click Add Media > Add Video in the upper left corner of the program interface. In the new window, choose one or more video files to convert. If you want to add DVD Video, click Add DVD > Open DVD and choose your DVD.

Choose the Desired Output Format

To review the list of available formats, open the Video tab and choose the video format you want: AVI, MP4, FLV, MOV, WMV, and many more. You can either choose a preset with a predefined resolution, for example, MP4 H.264 - 640x480 or specify a different resolution later on.

If you want to prepare video for viewing on an iPhone, iPod, iPad, PSP, or another portable device, click Devices and choose the appropriate preset for your device. Your video will be converted at the optimal resolution for viewing on that mobile device.

There's also an option to detect your device automatically by connecting your device to the computer and clicking the Cell Phone icon in the lower right corner.

Specify Video Resolution (Optional)

You can skip this step if you have already selected a format or device preset with a predefined resolution.

Click the Cogwheel icon below the presets ribbon. Locate the Frame size drop-down list. Here, you can either choose one of the standard resolutions, or select Custom and specify your desired resolution in the Width and Height boxes to the right. You may also want to choose a resize method from the drop-down list to optimally fit your video into the selected dimensions. Click OK to apply the changes.

Convert Your Video

By default, converted videos are saved to the Movavi Library folder. If you want to change the output folder, click the Folder icon to the right of the Save to field and choose another folder or create a new one and click OK.

Click the Convert button and wait for the process to finish. After the conversion is complete, the folder containing the converted files will open automatically.
