How To REMOVE OBJECTS From VIDEO In Davinci Resolve (Studio)

Learn how to effectively erase moving objects from your video using the powerful Object Removal tool available in DaVinci Resolve Studio.

To remove objects from a video in DaVinci Resolve Studio, you must utilize the Color page to mask the unwanted item with a Power Window, track its motion, and apply the AI-powered Object Removal plugin. By analyzing the pixels outside the masked area, the Neural Engine automatically reconstructs the background, effectively painting over the object as the camera moves.

What is the Object Removal tool in DaVinci Resolve Studio?

The Object Removal tool is a Neural Engine (AI) plugin exclusive to the paid DaVinci Resolve Studio version.

It is designed to eliminate distracting elements from a moving video—such as a boom mic dipping into the frame, a stray light stand, a logo on a shirt, or a person walking through the background. Instead of requiring tedious frame-by-frame clone stamping in dedicated VFX software like After Effects, the tool tracks the camera's motion and mathematically generates a clean background plate to seamlessly cover the masked object.

How to set up an Object Removal node on the Color page?

The entire object removal process takes place within the node-based architecture of the Color page, requiring a specific sequence of masking and tracking.

Navigate to the Color Page: Select the clip containing the unwanted object on your Edit timeline, then click the "Color" tab at the bottom of the screen.
Add a New Node: Right-click your existing node tree or press Option+S (Mac) / Alt+S (Windows) to create a new Serial Node.
Add the Plugin: Open the "Effects" panel on the top right. Scroll down to the Resolve FX Revival section, find the "Object Removal" plugin, and drag it onto your newly created node.
Connect the Alpha Channel: To tell the plugin exactly what area to replace, you must feed it an alpha mask. Click the blue square output on the node containing your mask (created in the next section) and drag a line to the blue triangle input on your Object Removal node.

How to mask and track the unwanted object?

Before the AI can generate a clean background, it must know exactly where the object is located throughout the clip.

Draw a Power Window: Select the node before your Object Removal node. Click the "Window" icon (the circle with a dot) in the middle toolbar. Choose a Pen or Circle tool and draw a tight mask around the object you want to erase.
Open the Tracker: Click the "Tracker" icon (looks like crosshairs) next to the Window icon.
Track the Motion: Place your playhead at the beginning of the clip and press the "Track Forward" button (the play icon). DaVinci Resolve will automatically track the object's movement across the screen. If the track slips, adjust the mask manually and track again.
Invert the Mask: Depending on how your nodes are connected, you may need to invert the mask so the Object Removal tool knows the masked area is the target for deletion, not the area to preserve.

How to execute the Object Removal process?

Once the mask is drawn, tracked, and connected to the plugin, you must command the Neural Engine to analyze the scene and build the replacement pixels.

Select the Plugin Node: Click on the node containing the Object Removal plugin.
Open the Inspector: Ensure the Effects Inspector is open to view the plugin settings.
Click Scene Analysis: Click the "Scene Analysis" button. DaVinci Resolve will calculate the background pixel data. This step may take several minutes depending on the clip length and your computer's GPU power.
Build Clean Plate: Once the analysis is complete, click "Build Clean Plate." The software will instantly generate the replacement pixels, and the object will vanish from the viewer.

How to refine a messy object removal result?

If the object removal leaves a blurry smudge, a repeating pattern, or fails to match the lighting, the AI needs more help understanding the background.

To refine the result, adjust the settings in the Effects Inspector:

* Search Area: Increase or decrease the search area. This tells the AI how far outside the mask it should look for clean replacement pixels.

* Blend Mode: Change the blend mode to help the clean plate match the lighting and texture of the surrounding area.

* Manual Clean Plate: If the automated clean plate fails (common on complex backgrounds), check the "Use External Clean Plate" box. You can export a single frame to Photoshop, manually clone stamp out the object, re-import that frame into the Media Pool, drag it into the node graph, and connect it to the green input of the Object Removal node as a perfect reference.

What are the limitations of the Object Removal tool?

While incredibly powerful, the Object Removal tool is not magic and requires specific conditions to work flawlessly.

* Static Backgrounds are Best: It works perfectly on static, uniform backgrounds like grass, a clear sky, or a concrete wall. It struggles heavily with highly complex, moving backgrounds (like a crowd of people or moving traffic).

* Subject Crossing: If the object you are removing crosses behind or in front of your main subject, the mask will break, and the tool will pull pixels from the subject's face or body, ruining the shot.

* Lighting Changes: Rapid changes in exposure, shadows moving across the object, or lens flares will confuse the AI's clean plate generation.

* Studio Version Only: This feature is locked behind the paid DaVinci Resolve Studio license. It is not available in the free version.

How to speed up workflows before doing VFX work?

VFX work like object removal is incredibly taxing on computer hardware. Attempting to scrub through a timeline filled with unrendered Object Removal nodes is nearly impossible.

Professional editors avoid this by locking their edit before touching VFX:

* Extract with AI: They upload raw footage to Cutsio, search the transcript, and extract the best moments via XML.

* Import to Resolve: They import the pre-cut timeline into DaVinci Resolve.

* Apply VFX Last: Only after the narrative edit is completely locked do they move to the Color page to apply heavy plugins like Object Removal. This ensures they don't waste hours rendering VFX on a clip that ultimately gets cut from the final video.

Frequently Asked Questions (FAQ)

Can I remove objects in the free version of DaVinci Resolve?

No, the automated Object Removal plugin is a Neural Engine feature exclusive to DaVinci Resolve Studio. In the free version, you must use the Fusion page to manually track a mask, use a TimeStretcher node to pull clean pixels from a different frame in time, and merge them over the object—a highly complex and time-consuming manual process.

Why is my playback stuttering after applying Object Removal?

The Object Removal tool requires massive GPU processing power to calculate the clean plate on every frame. Once you have built the clean plate and are satisfied with the result, right-click the node containing the plugin and select "Node Cache > On." DaVinci Resolve will background-render the effect (indicated by a blue or red line over the clip on the Edit page timeline), restoring smooth, real-time playback.

What is the difference between Object Removal and Patch Replacer?

The Patch Replacer plugin is a simpler tool used for small, static blemishes (like a sensor dust spot or a pimple on a face). You manually drag a source box over clean skin and a destination box over the blemish. Object Removal is designed for large, moving objects and uses AI to automatically calculate the background replacement without needing a manual source box.

By mastering Power Windows, tracking, and the Scene Analysis engine, you can use the Object Removal tool in DaVinci Resolve Studio to salvage shots that would otherwise be unusable.
