Getting a great 4K upscale is about more than just applying a filter. Follow these pro-tips to ensure the best possible outcome:
By default, After Effects uses standard mathematical interpolation methods like Bilinear or Bicubic scaling. These methods look at neighboring pixels and average their colors to fill the gaps. While this prevents harsh pixelation, it creates a massive downside: soft, blurry, and muddy edges. Intelligent Upscaling Plugins

Unlike standard scaling in After Effects—which simply stretches existing pixels—Instant 4K uses to generate new pixels based on the surrounding data. This process includes advanced sharpening and anti-aliasing to preserve edges and fine details, ensuring that the upconverted video maintains a crisp, professional look. Key Features:
Unmatched visual clarity; excellent noise reduction and deinterlacing.
It uses an advanced interpolation algorithm combined with directional sharpening to minimize blurring along edges.
If you do not have budget for third-party plugins, After Effects includes built-in tools that outperform basic transform scaling. Detail-Preserving Upscale
Standard bilinear or bicubic scaling stretches existing pixels. This process creates blurry edges, muddy textures, and noticeable artifacting.
Go to Composition > Composition Settings and set your resolution to 4K (typically 3840x2160 ).

You might wonder: Why can't I just use the "Frame Blending" or "Pixel Motion" in After Effects?
