How to Resize Video
Sometimes you may need to resize your video or change its aspect ratio – for example if you have a wide screen (16:9 aspect ratio) HD video that you want to watch on the 4:3 aspect ratio screen of your iPod Classic. If you try to upload a video with an incorrect aspect ratio to your device, it will either not play at all or will be displayed incorrectly (probably with stretched-out images).
You can correct the problem easily by resizing video with Movavi Video Converter. The program supports all popular video formats, including AVI, MOV, MP4, MPEG, and WMV, so you can use it to resize movies in almost any format, as well as reduce video file size if necessary. Movavi Video Converter offers plenty of ready-made presets for popular websites and social networks, enabling you to resize video for YouTube or Facebook and upload clips to your account right from the program.
To start working with Movavi’s video resizer, download and install the software on your computer. Using Movavi Video Converter you can convert your video to any popular format and resize it in just 5 easy steps:
- Open Movavi Video Converter and add your video file to the program.
- Select the desired output format for conversion.
- Click the Settings button next to the Preset list.
- Specify the resolution and aspect ratio of your video, and choose the desired resize method and quality.
- Start conversion.
Movavi Video Converter enables you to select options such as resize method and resize quality. First, let’s review the available resize methods: Stretch, Letter Box and Crop (see Figure 1).
- Stretch – the original video frame is stretched (or condensed) to the specified frame size (width and height).
- Letter Box – the original video frame is placed within the output frame. The aspect ratio stays the same, and the free space between the input and the output frames appears as black bars. This method is set by default in Movavi Video Converter.
- Crop – the original video frame is placed within the output frame. The aspect ratio stays the same, and the parts of the input frame that go beyond the output frame size are cut off.
When using the first method, the picture can be stretched (or condensed) while, in the other two, the proportions remain unchanged but in different ways.
With regard to resize quality, two options are available: Normal (Fast) and Best (Slow). Figure 2 shows the differences between these two options.
- Normal (Fast) – this mode works faster than the other (as is evident from the names), but the quality of the output video is lower. When you increase the frame size (when the input video frame is smaller than the output), there may be visible pixelation effects.
- Best (Slow) – the process works much more slowly for this mode, but the quality of the output video is higher. When you increase the frame size, the image is smoothed and there is no pixelation.
Now you know about the resize types available in Movavi Video Converter and can choose the one that’s right for you. Resizing video is really easy – download the program now and try it yourself!
