DetailRecovery

Resolve 21 places Detail Recovery in Resolve FX Texture and marks it Studio Version Only. Blackmagic describes it as a two-input operation: image detail is extracted from the second input and re-added to the first. The same Resolve FX appears on the DaVinci Resolve Fusion page through OpenFX/Resolve FX Texture; native Resolve FX are not available as standalone Fusion Studio nodes.

The point is not simply to sharpen everything. One version of the shot becomes the receiving image—for example a denoised, softened, beauty-treated or aggressively processed base—while the second version acts as the donor of useful high-frequency texture and edge structure.

By default Input 1 is the receiving image and Input 2 is the detail donor. Transfer Direction can reverse those roles. Choose the direction before tuning extraction; excessive Strength cannot repair a donor/receiver assignment that is backwards.

Both inputs must be spatially and temporally aligned. If the donor differs in transform, crop, stabilization, retime or frame content, high-frequency transfer becomes doubled edges, ghosting and false texture. Detail Recovery performs no tracking, warping or optical correspondence between mismatched images.

Frequency Cutoff controls how much spatial detail is admitted into recovery. Resolve 21 defines the direction explicitly: lower values isolate finer detail while higher values include progressively larger structures. Cutoff is therefore a scale selector, not merely a strength or sharpness radius control.

Detail/Edge Balance shifts recovery between broader detail information and stronger edge-oriented structure. The manual defines the conceptual balance but does not provide a universal production preset for every shot, so the reliable method is to judge the extracted component with Preview Detail rather than copy a numeric value blindly.

Strength exaggerates or attenuates the already extracted detail component. If Preview Detail contains the right information but the final image becomes crunchy or rings, reduce Strength. If Preview itself is dominated by noise or large unwanted shapes, fix the donor, Cutoff or Balance instead.

Detail Mix is easy to misread. Resolve 21 states that at 1.000 the extracted detail is blended with the receiving image, while at 0.000 the extracted detail replaces overlapping receiving pixels. This is not a conventional wet/dry slider where zero means no effect; 0 and 1 are two different integration endpoints.

Preview Detail is a diagnostic view of the extracted component computed by Frequency Cutoff and Strength. A useful preview contains the pores, fabric texture, fine edges or other high-frequency information you actually want to return—not a second full copy of the source and not mostly noise. Disable Preview before judging the final receiver.

Detail Recovery is especially useful after denoise, beauty/smoothing, mild optical softening or aggressive tonal treatment when the base has become cleaner but lost believable fine structure. It is also useful in controlled restoration when a trustworthy aligned donor exists. Without such a donor, Sharpen or Texture Pop may be the more honest tool.

Do not confuse standalone Resolve FX Detail Recovery with the Detail Recovery subsection inside Resolve FX Beauty. Beauty's section restores edges/details within its own smoothing pipeline; the standalone effect is a separate two-input node with Transfer Direction and Frequency Cutoff.

The captured Fusion Inspector confirms six effect-specific controls in the target UI: Transfer Direction, Frequency Cutoff, Detail/Edge Balance, Strength, Detail Mix and Preview Detail. Common host/Settings controls should not be used to hide an incorrect donor, extraction band or Strength.

A reliable sequence is: align both branches → choose receiver/donor → set Transfer Direction → enable Preview Detail → tune Frequency Cutoff → inspect Detail/Edge Balance → set Strength → A/B Detail Mix 0/1 → disable Preview → judge the final output at 100% and in motion.

Detail Recovery is best understood as frequency transfer between two versions of one shot rather than a sharpening effect.

Receiver and donor must represent the same moment in time; even a one-frame offset can turn motion into false high-frequency detail and doubled edges.

Spatial registration matters just as much: crop, resize, stabilization, lens correction and transforms should match before the node.

Transfer Direction should be fixed first. The default Input 2 to Input 1 means detail is extracted from the second input and returned to the first.

Reversing Transfer Direction fully swaps donor and receiver roles; it is not equivalent to changing Strength or Mix.

Frequency Cutoff selects the spatial scale of extracted structure. Lower values isolate finer detail while higher values progressively admit larger forms.

Cutoff is not an amount control. At the same Strength, different Cutoff values can transfer pores/noise at one end and much larger edge/texture structures at the other.

Preview Detail is the clearest diagnostic view of what actually enters the recovery layer.

If Preview Detail starts to resemble a full copy of the donor, the extraction band is too broad for a typical microdetail workflow.

If Preview contains mostly noise/grain, the donor or Cutoff is wrong; lowering Strength only reduces amplitude without changing the type of information extracted.

Detail/Edge Balance shapes the character of the extracted component after the broad frequency band is established.

Do not reduce Balance to a universal numeric texture-versus-edge recipe without target-build evidence; judge it visually in Preview and the final receiver.

Strength changes amplitude of already-extracted detail. It cannot repair donor choice, Cutoff or alignment.

Excessive Strength turns useful texture into crunchy high-frequency enhancement, especially on skin, hair, fabric and compressed footage.

Detail Mix has unusual semantics: 1.0 blends extracted detail with the receiver while 0.0 replaces overlapping receiver pixels with the extracted component.

Therefore node bypass and Detail Mix=0 are different tests. Bypass shows the receiver without Detail Recovery; Mix=0 is another integration endpoint of an existing extraction.

Preview Detail is not a separate physical output; it is a diagnostic representation of the same Output path and must be disabled before delivery.

After denoise, the original source is often a useful donor because it retains high-frequency texture, but it also carries noise and compression artifacts that may transfer.

After beauty/smoothing, a donor can restore pores and hair but can also reintroduce blemishes/noise intentionally removed by the smoothing stage.

After optical blur or diffusion, Detail Recovery can restore edge/texture character only because the donor already contains that information; it does not reconstruct detail from nothing.

If donor and receiver use different grading or local-contrast treatment, their high-frequency difference can include tonal artifacts.

Two branches from one MediaIn are generally safer than two separately imported files because timing and framing are easier to guarantee.

Detail transfer between different takes or cameras requires a separate registration/warping pipeline; Detail Recovery does not solve correspondence.

Alpha/coverage should also match between inputs. Different mattes or premultiplication states can create edge artifacts even when RGB geometry appears aligned.

On premultiplied foregrounds, inspect the recovered detail over the real background because contaminated RGB behind alpha can appear after Merge.

Detail Recovery is not a substitute for Sharpen/Unsharp Mask; if no trustworthy donor exists, a one-input sharpening tool can be simpler and more causal.

Standalone Detail Recovery is not the same as the Detail Recovery section inside Beauty; the standalone effect has two image inputs and Transfer Direction.

For clean A/B work, keep donor/receiver, Cutoff and Balance fixed and change one variable at a time.

If one branch contains a retime while the other does not, high-frequency mismatch changes over time and creates crawling/ghosting.

Resolution mismatch or scaling can create subpixel edge offsets that only become obvious at 100%.

For automation, Transfer Direction and Detail Mix should be confirmed from target-build serialization rather than guessed from visible labels.

Performance depends on resolution, extraction settings and the two image branches, so profile the actual restoration graph.

Static documentation defines semantics while exact Balance behavior, serialization, alpha handling and runtime performance remain live-certification items.
