How to Change Video Resolution
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).
You may need to reduce video resolution, for example if you want to upload high resolution video to your mobile device, since these devices often support only specific resolutions. Increasing video resolution is a pretty rare practice, and there are good reasons why. If you simply increase the resolution of a video, the quality will not improve, but the video size may grow. However, sometimes these transformations may be essential. 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 not less than 720 × 480.
Movavi Video Converter is powerful, yet easy-to-use conversion software that lets you change video resolution easily. It supports the most popular video formats and offers ready-made presets for even the newest mobile devices.

Step 2: Add Video to the Program
Run Movavi Video Converter and click the Add Video button 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 the Add DVD button and choose your DVD.
Step 3: Choose the Desired Output Format
To check the list of available formats, open the Convert to drop-down menu. Click Video and audio and choose the video format you need: AVI, MP4, FLV, MOV, WMV, etc. You can either choose a preset with a predefined resolution, for example, MP4 H.264 640 x 480 or specify a different resolution later on. If you want to prepare video for 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 your mobile device screen.
Step 4 (Optional): Specify Video Resolution
You can skip this step if you have already selected a format or device preset with a predefined resolution.
Click the Settings button next to the Convert to list. Find the Frame size drop-down box. Here, you can either choose one of the standard resolutions, or select Custom and specify the required resolution in the Width and Height boxes to the right. You might also want to choose a resize method from the respective drop-down box to optimally fit your video into the selected dimensions.
Click OK to apply your changes. Don't forget that you can use the player to preview how your video will look after resizing. Just click Output next to the player controls and play the video!
Step 5: Convert Your Video
By default, converted videos are saved to the Movavi Library folder. If you want to change the output folder, click the Browse button next to the Destination field and choose an existing 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.
