Scale

Scale and Resize change resolution: Scale uses a relative multiplier, while Resize uses exact dimensions. The previous description of Scale as content scaling within an unchanged canvas is corrected against BMD21. A 1920×1080 input at Size 0.5 becomes 960×540.

Viewer Fit may display the source and smaller output at similar apparent sizes. Read the resolution information and compare at 100% zoom, or a size change can look like no effect.

The documented Scale has one orange Input. The previous Effect Mask is removed from the Scale diagram. Use an appropriate Transform/Merge branch when animating element size or limiting a local result.

Connecting a smaller branch to Merge Background changes the Merge canvas. To retain a 1920×1080 result, create a Background at that size and connect Scale to Foreground. This is separate from Edges Canvas/Duplicate.

BMD advises against animating Scale because the image dimensions change across frames. In the motion lesson, Scale Size remains constant and the animation keys belong to a separate Transform node.

Filter comparisons require the same Size, source and preview quality. With Only Use Filter in HiQ enabled, non-HiQ may use Nearest Neighbor. Sinc and Bessel also require Window Method, which is absent from the capture with Linear selected.

All 16 original parameter subjects and the original PNG are retained. The lessons use the existing Text+ interface for dimension changes, fixed-canvas composition and filter comparison. Native Resolve rendering and actual pixels remain unverified.
