BGRA / GPUResize 2
THE GPU RESAMPLING TOOLKIT

One toolkit.
Your choice.

A Swiss Army knife for image resampling.
Classic filters. GPU speed. You choose the method.

Explore the methods

Works in Premiere Pro and DaVinci Resolve, plus After Effects. Resolve setup: included Fusion macro ↗

01 / CLASSIC FILTERS

Different filters. Different results.

Classic resampling methods familiar from scientific imaging.
From Bilinear and B-Spline to Mitchell, Lanczos and Kaiser.

Bilinear ↔ Lanczos 3256 → 768 px · 1 pass · sharpening off
02 / PIXEL ART

Pixel art has
options, too.

Compare Nearest, Scale2x, Eagle and FSR 1 EASU on the same pixel artwork. Choose a method on each side and drag to explore the edges.

03 / DOWNSCALING

Downscaling is part of the toolkit.

Explore how Bilinear and Area handle a reduction.
The right choice depends on the image and the task.

04 / POST-SHARPEN

The finishing touch. Your amount.

Compare sharpening off, RCAS and Unsharp Mask after the same resize. Choose 50% or 100% on either side. Sharpening changes local contrast; judge the texture and edges together.

05 / MULTIPASS

Resize in steps. In either direction.

Compare 1, 2, 4 or 8 passes through intermediate sizes. Keep the final dimensions fixed and choose the result you prefer. More passes are a choice, not a quality guarantee.

06 / CREATIVE RESIZING

Resizing glitch effects.

Push Content Aware into expressive distortions. Sweep multipass from 1 to 16 and back while the output dimensions stay fixed. Let the image bend, stretch and shift.

PRACTICAL CONTROLS

Choose the filter.
Build the process.

Multipass downscale. Reduce through intermediate sizes.
Stairstep upscale. Enlarge in progressive steps.
Post-sharpen. Finish with optional RCAS or Unsharp Mask.

Set the dimensions, choose a method and control the number of passes. Compare the result. No single filter suits every image.
