RESOLVE FX · MANUAL FRAME-AWARE RESTORATION
Dust Buster.
Patch the defect.
Choose the clean source.
Dust Buster is the surgical cleanup pass after automation. Place the smallest patch over a transient defect, decide whether clean texture should come from another frame, the current frame or an explicit clone source, prove the intervention with diagnostic outputs, then approve it in playback.
Rect / Ellipse / Point
Temporal / Spatial / Clone
Locations / Differences
In the lab, switch Fast motion on and compare Auto with +/-1 Frame in both directions. Then choose Texture, compare Spatial with Blend Clone and open Difference Magnitude. The point is to see that source choice comes before softness or Global Blend.

The defect is local. The source decision is not.
Dust Buster is designed for transient dirt and blemishes that need user-guided, frame-specific repair. The visible patch is only the boundary; the important decision is where believable clean image information should come from.
Dust Buster is manual frame-aware repair.
The effect does not automatically search for every defect. You identify transient dust or dirt, move to the affected frame and draw a patch. That makes Dust Buster slower than an automatic pass, but gives precise control over every difficult leftover defect.
Choose the clean source before polishing the patch.
Auto and +/-1 / +/-2 Frame use temporal information; Spatial builds a fill from the current frame; Clone and Blend Clone use an explicitly chosen source region. These strategies solve different failure modes, so Soft Edges cannot repair temporal mismatch and Global Blend cannot repair a bad clone source.
Keep each patch minimal and auditable.
The larger the patch, the higher the risk of frozen grain, repeated texture, halos or visible fill patterning. Cover only the defect first, then inspect Patch Locations and Differences. Increase Size Adjust only when the damaged edge genuinely remains outside the patch.
Patched Result shows the finish but not the intervention. Patch Locations confirms spatial coverage; Differences shows actual pixel changes; Difference Magnitude exaggerates subtle changes. Only then return to Patched Result and review several neighboring frames in motion.
02THE ACTUAL PANEL
Five layers: placement, source, patch, UI, output.
Seven native Resolve captures anchor every visible control family. Disabled items in a capture are contextual: for example, Spatial-only controls can be dimmed while Auto is active.
01 · GENERAL / NAVIGATION
Find the frame and place the smallest useful patch.
- Draw Rect / Draw Ellipse / Place Patch
Rect suits elongated defects, Ellipse suits round dust/spot geometry, and Place Patch is fast for tiny point blemishes. Geometry does not choose the source strategy; it defines the spatial footprint of the repair.
CheckChoose the shape from the defect and keep it minimal rather than drawing a large convenient region.
- Show Patches / Reset Frame
Show Patches displays patch overlays for placement checks. Reset Frame clears repairs on the current frame so that frame can be rebuilt.
CheckBefore delivery, make a Show Patches pass and confirm no patch unintentionally covers useful content.
02 · PATCH TYPE
Choose the repair source that matches the failure.
- Auto
Official documentation describes Auto as comparing the current frame with two previous and two following frames and selecting the best source. Suitable frames two away are prioritized to reduce frozen grain.
CheckIt is a strong first choice for isolated film dust, but always inspect moving texture and grain on neighboring frames.
- +/-1 Frame
Drawing direction selects the temporal source: left-to-right uses the next frame, while right-to-left uses the previous frame. This provides an explicit, temporally close source.
CheckUse it on faster motion or when Auto picks a poor neighbor. A/B both directions.
- +/-2 Frames
Works like +/-1 Frame but samples a frame two positions away. Useful when the nearest frame is also damaged or +/-1 produces frozen grain, but spatial mismatch can increase.
CheckInspect moving edges, texture phase and repeated grain because the temporal distance is larger.
- Spatial + Fill Method
Spatial builds the repair from surrounding pixels in the current frame. Fill Method offers Grid, Horizontal, Vertical, Patchy and Smooth, each interpolating the surroundings into the patch differently.
CheckLarge Grid patches can reveal a pattern; Smooth can become overly soft. Choose the method from local texture.
- Clone / Blend Clone
Clone copies an explicitly chosen source region. Blend Clone uses the same idea but integrates the copy more softly into the underlying image. They are useful when temporal and automatic spatial sources are unreliable.
CheckThe source must match lighting, texture, perspective and motion context; softer blending cannot hide a fundamentally bad source.
03 · PATCH OPTIONS
Refine the selected patch without confusing the repair model.
- Variability
This control applies to Spatial patches and makes the fill less uniform. It can keep a repair from looking unnaturally smooth inside grain or noisy texture.
CheckRaise only until texture matches; variability should not become a new visible noise pattern.
- Soft Edges
Softens the patch boundary so the transition between repaired source and original image does not read as a hard contour.
CheckOn a high-contrast edge too much feather smears useful structure; on skin or sky too little can reveal the patch boundary.
- Size Adjust
Changes the size of an existing patch. Use it when the defect slightly escapes the original shape, not as a substitute for placing a better patch.
CheckAfter resizing, re-check Patch Locations and Differences.
- Mute / Delete Patch
Mute disables a particular patch without deleting it and can be used when patch presence must vary over time. Delete Patch removes the selected repair.
CheckUse Mute for A/B; use Delete only when the patch is no longer needed.
04 · ADVANCED UI
Speed up the manual operation without changing repair intent.
- Clone Sticks to Mouse
In Clone / Blend Clone it immediately moves the interaction to source-sample positioning after placing the patch, reducing clicks.
CheckThis is a UI preference, not a quality mode. The source still needs deliberate placement.
- New Patches Stay Selected
Keeps a newly created patch selected so Patch Type and Patch Options can be edited immediately.
CheckUseful for dense cleanup, but confirm which patch is active before changing options.
- UI Line Thickness
Changes only the on-screen outline thickness. It does not alter the rendered image.
CheckSet it for monitor resolution and control visibility; do not mistake it for patch feather.
05 · OUTPUT / MIX
Diagnose the intervention first, then meter the finish.
- Output Mode
Patched Result shows the finish; Patch Locations maps placed patches; Differences shows actual changes; Difference Magnitude exaggerates those differences.
CheckDo not approve a repair from Patched Result alone. Check Locations and Differences at least once.
- Global Blend
Mixes the complete Dust Buster result with the original. It is the final dose after each patch is already logically correct.
CheckIf Blend must be reduced heavily, first find the bad patch or wrong source strategy.
Two details are easy to miss. In +/-1 and +/-2 Frame modes, drawing direction selects whether the source comes from the previous or next side of time. In Spatial mode, Fill Method changes how surrounding current-frame pixels are synthesized inward; it is not another temporal selector.
03READ THE PATCH BEFORE TRUSTING IT
A good repair is small, explainable and invisible in time.
Output Mode gives you four different questions. Patched Result asks whether the finish looks right; the other three explain where and how the intervention happened.
Is the footprint minimal?
The white-on-black patch map should cover only intentional defects. Large or accidental regions are easier to spot here than in the repaired picture.
Shrink or reposition the patch before changing source strategy.
What pixels are actually changing?
Differences exposes replacement texture, edge changes and motion mismatch that a pleasing still can hide. A clean repair changes exactly what is needed and little else.
If useful texture lights up outside the defect, revisit patch size or source.
Can a subtle mismatch be amplified?
Difference Magnitude makes weak intervention easier to inspect. Use it for grain, fine texture and soft gradients where a temporal or clone mismatch may be almost invisible at normal contrast.
Return to Patched Result only after the diagnostic views are clean.

04PATCH-FIRST WORKFLOW
Find first. Source second. Blend last.
The efficient order is modified frame → minimal patch → source strategy → patch refinement → diagnostics → playback/QC. Every later step assumes the earlier decision is already correct.
Work on the actual damaged frame
Step through the shot, stop on the transient defect, and use modified-frame navigation later for QC. Dust Buster is intentionally frame-aware and manual.
Teaching workflow, not a literal Resolve node graph. The causal order matters: patch geometry and source strategy come before edge polish, diagnostics and Global Blend.

05BUILD IT IN RESOLVE
Four defects. Four different source decisions.
Use real moving footage, not a still. These exercises are decision workflows, not universal values: motion, grain, scan cadence, texture scale and defect geometry determine the safe repair.
Single-frame dust spot
Remove transient dust with real neighboring texture without frozen grain.
PrepareUse footage or a film scan where a dust spot exists on only one frame while surrounding texture continues moving.
- 01
Place a minimal Ellipse or Patch exactly over the defect and enable Show Patches.
- 02
Start with Auto, then compare +/-1 Frame in both directions.
- 03
Switch to Differences and confirm that only the necessary area changes.
- 04
Return to Patched Result and play at least several neighboring frames.
The dust is gone, grain/texture does not freeze, and the patch is invisible in motion.
Dust over fast motion
Avoid an Auto temporal source that no longer matches moving geometry.
PrepareUse a frame where the defect overlaps a moving edge, fabric, hair or another rapidly changing detail.
- 01
A/B Auto against +/-1 Frame and test both drawing/source directions.
- 02
If neither temporal source matches, switch to Spatial and compare Fill Method options.
- 03
Keep the patch as small as possible, then tune Soft Edges.
- 04
Inspect Difference Magnitude for ghosted or repeated structure.
The repair contains no displaced detail from a neighboring frame and no visible fill pattern.
Difficult texture: Clone / Blend Clone
Choose a clean source region manually when temporal and Spatial repair are unreliable.
PrepareUse a stable shot with repeatable texture such as a wall, fabric, film texture or surface, plus a defect over important detail.
- 01
Create a minimal patch, choose Clone and place the source on matching texture and lighting.
- 02
Compare Clone and Blend Clone at the repair boundary.
- 03
Tune Soft Edges only after the source is correct.
- 04
Check Differences and playback for obvious repeated texture.
The source does not reveal itself through repetition, perspective/lighting match, and the patch boundary is not visible.
QC a long manual restoration pass
Review dozens of patches systematically instead of hunting across the timeline.
PrepareUse a clip containing several repaired frames.
- 01
Use First/Next Modified Frame to step through every repaired frame.
- 02
Enable Patch Locations and confirm every footprint is minimal.
- 03
Use Differences / Difference Magnitude to find unexpected texture changes.
- 04
Return to Patched Result and play the full section before delivery.
Every patch is accounted for, there are no accidental regions, temporal transitions are clean, and Global Blend is not hiding a bad repair.
06MATCH THE FAILURE TO THE TOOL
Automation, persistent repair and whole-frame replacement are different jobs.
Dust Buster sits between automatic cleanup and heavier manual restoration: it is explicit enough for difficult defects but still optimized around small frame-specific patches.
| FX | What it targets | Choose it when |
|---|---|---|
| Automatic Dirt Removal ↗ | Automatic transient dust/dirt detection across the frame. | First pass when there are many small defects. |
| Dust Buster | Manual frame-specific patches with temporal, Spatial and Clone sources. | Difficult one- or two-frame defects that need explicit control. |
| Dead Pixel Fixer ↗ | Persistent blemishes / dead pixels that remain fixed through the clip. | The defect stays at a stable position instead of appearing on one frame. |
| Frame Replacer ↗ | Replacement of an entire damaged frame rather than a small patch. | Damage is too large or the entire frame is unsuitable for local repair. |
07DIAGNOSE THE SOURCE, NOT THE MIX
Frozen grain, ghosts and fill patterns have different causes.
Do not reach for Global Blend first. A visible repair usually points upstream: wrong temporal source, oversized patch, unsuitable Fill Method, clone mismatch or insufficient edge integration.
01The patch looks like frozen grain.+
Likely cause: The temporal source is unsuitable or a large patch makes repeated texture obvious.
Fix: Compare Auto, +/-1 and +/-2 Frames, shrink the patch and inspect Difference Magnitude in playback.
02Moving detail produces a ghost or displaced texture.+
Likely cause: The temporal source does not match the motion or geometry.
Fix: Try the opposite +/-1 direction, then Spatial or a manual Clone/Blend Clone source.
03Spatial fill reveals a pattern or an overly smooth patch.+
Likely cause: Fill Method does not match texture scale/direction; Variability is too low or the patch is too large.
Fix: Compare Grid/Horizontal/Vertical/Patchy/Smooth, reduce patch size, then add Variability carefully.
04The patch boundary is visible.+
Likely cause: The source differs in tone/texture or Soft Edges are too low.
Fix: Fix the source/strategy first, then feather with Soft Edges; use Blend Clone only after the source is correct.
05Global Blend must be reduced heavily.+
Likely cause: One or more patches are logically wrong and Blend is only hiding their contribution.
Fix: Find the offending patch with Patch Locations/Differences, fix its source or footprint, then use Blend only for final dosing.
08BEFORE DELIVERY
Approve every modified frame, then approve the shot.
Dust Buster is manual by design, so QC must be equally explicit. Use the navigation controls and diagnostics to make sure no forgotten patch, frozen texture or accidental coverage survives into delivery.
09FAQ
Practical Dust Buster questions.
How is Dust Buster different from Automatic Dirt Removal?
Automatic Dirt Removal automatically searches for transient contamination and is useful as a first pass. Dust Buster is intentionally manual: you place a patch on a specific difficult defect and choose a temporal, Spatial or Clone source.
How is Dust Buster different from Dead Pixel Fixer?
Dust Buster primarily targets transient dust/dirt that lasts one or two frames. Dead Pixel Fixer targets persistent blemishes that remain at a fixed position through the clip.
Which Patch Type should I try first?
For isolated dust, start with Auto and then compare +/-1 Frame. With strong motion move to Spatial; when you need a specific clean area, use Clone or Blend Clone.
Why use Patch Locations and Differences?
They separate intervention geometry from the flattering final image. Locations shows where patches exist, Differences shows what they change, and Difference Magnitude makes subtle intervention easier to see.
Can one large patch repair a large stain?
It can, but the risk of patterning, frozen texture, source mismatch and visible boundaries grows quickly. Complex damage may be better handled with several minimal patches or another tool such as Frame Replacer.
