# Downscale

Turning IMAX into “eh, max.”

## What it is

Downscaling is the process of converting a video from a higher resolution (e.g., 4K) to a lower one (e.g., 1080p or 720p). It reduces file size by shrinking the number of pixels while retaining reasonable quality and the same aspect ratio.

## Why it's important

High-resolution files are heavy - difficult to edit, stream, or store. Smaller resolutions are easier to upload, stream, and store. Downscaling helps with faster rendering, platform compatibility, and accessibility for devices with lower display resolutions.

## When/how to use

Downscale when exporting for web, social media, or mobile. Always ensure the source footage is high quality, so detail isn’t lost during the process.

## Best Practices

1. **Maintain aspect ratio –** Prevent stretching or squashing by locking proportions when resizing.
2. **Choose the right algorithm –** Use high-quality downscaling methods (bicubic, Lanczos) to preserve detail.
3. **Export for platform specs –** Downscale to meet delivery requirements (e.g., smaller sizes for web streaming).
