JPEGDamage

This is an artistic artifact simulation in Resolve FX Texture. The rendered file may use ProRes, DNxHR or another format; the damaged pattern is already in its pixels. The node neither analyzes compression history nor proves that a source was previously recompressed.

Quality changes degradation; the manual describes reducing image bit depth. Resolution controls the apparent size of macroblocks rather than output canvas dimensions. Adjust them separately to distinguish damage severity from block size.

Block Aspect Ratio changes block proportions. The captured value of 1.0 is a useful starting point; elongated blocks are a styling choice, not a command to change the composition pixel aspect ratio.

Frequency Scale sharpens or emphasizes the frequency pattern. Scale Component targets All Frequencies, X-Frequency or Y-Frequency. The axis name refers to a frequency component; it does not by itself prove the direction of visible bands.

Inspect the result after the Resize/Transform operations that determine the insert’s final size. Later scaling can smooth fine blocks or exaggerate large ones. Deliberate damage combines with delivery-codec artifacts, so inspect an exported segment.

To damage only a screen, send the processed branch to Merge Foreground, the original to Background and Rectangle to the Merge Effect Mask. This separates image and mask streams without assuming extra JPEGDamage wrapper sockets.

Practice numbers are reproducible comparison points rather than universal presets. The exact Quality scale and alpha/HDR behavior require checks in the installed version; a static guide does not replace native rendering.
