How to Resize Output with FFmpeg

FFmpeg is a powerful and versatile tool that can be used for a variety of tasks, including video processing and manipulation. One common task that FFmpeg is often used for is resizing output. This can be useful if you need to change the dimensions of a video or image file.

To resize output with FFmpeg, you can use the `scale` filter. For example, the following command would scale a video to 640x480:

ffmpeg -i input.mp4 -vf scale=640:480 output.mp4

This command tells FFmpeg to read an input file called 'input.mp4', apply the `scale` filter to resize it to 640x480, and then write the output to a new file called 'output.mp4'.

In addition to scaling, FFmpeg also has other filters that can be used to manipulate video and image files. For example, you can use the `crop` filter to trim the edges of an image or video, or the `resize` filter to resize it while maintaining its aspect ratio.

FFmpeg is a powerful tool with many features and options, but it can also be overwhelming for beginners. Greenshot, a free open-source screenshot tool for Windows and Mac, provides a simple way to capture screenshots and edit them without needing to know how to use FFmpeg.

In conclusion, FFmpeg is a versatile tool that can be used for a variety of tasks, including resizing output. By using the `scale` filter, you can easily resize video and image files to the desired dimensions. Whether you're working with images or videos, FFmpeg is a powerful tool that deserves to be in your toolkit.
