# Configuring default scaling (Fit with padding)
<a name="video-scaling-default"></a>

If you choose **Default (Fit with padding)** for your **Scaling behavior**, MediaConvert scales your video image to your output resolution. Then, if your input resolution has a different aspect ratio than your output resolution, MediaConvert pads your video image until it matches the dimensions of your output resolution.

For example, if your input file is `1280` pixels by `720` pixels and you specify an output resolution that is `640` pixels by `480` pixels, MediaConvert reduces the image size to `640x360` and then pads the top and bottom of the image so that the final video resolution is `640x480`. MediaConvert does not use cropping for the **Default** scaling behavior.

**Key**

The following key graphic shows input and output image width, height, cropping, and padding. In this key graphic, input dimensions (on the top and left) are in blue and output dimensions (on the right and bottom) are in red.

The following table shows example image scaling behavior when your input and output resolutions differ. For details about to read the images, reference the previous key graphic.
