Dead Pixel Fix in After Effects

Before fixing the dead pixel in post, confirm it is a sensor defect and not a defect on your editing display. If you test your display for dead pixels and find the same dot on your monitor, the issue is the display — not the camera. Sensor dead pixels appear in exported video files; monitor dead pixels do not.

To confirm: export a short clip and play it on a different screen. If the dot appears in the export on the second screen, the defect is in the sensor footage and needs to be fixed in After Effects.

The manual Clone Stamp method is the most reliable approach for dead pixel after effects work when you only have a small number of defective pixels. It requires no plugins.

1. Import your footage into After Effects and create a new composition from it.
2. Create a new Solid layer(Layer > New > Solid) the same size as the composition and place it above the footage layer. Set its blend mode to Normal.
3. Select the Clone Stamp tool from the toolbar (rubber stamp icon). Set the brush size to 3–5 pixels, hardness to 0%, and opacity to 100%.
4. In the Layer panel (double-click the Solid layer to open it), position the current time indicator at a frame where the dead pixel is visible.
5. Alt+click (Option+click on Mac) on a clean area of the footage immediately adjacent to the dead pixel to set the clone source.
6. Click directly on the dead pixel to paint the clone. Because the Solid layer is above the footage, the clone paints onto the solid and masks the defect on all frames.

For sensor dead pixels (fixed position in every frame), you only need to set the clone paint point once — it applies across all frames automatically.

The Smart Defect Fixer plugin (available for After Effects from aescripts + aeplugins) automates dead pixel detection and removal. It is the faster option for fix dead pixel after effects work when dealing with multiple defects or long footage. The dead pixel fixer after effects plugin scans a sample frame, identifies anomalous pixels by comparing their values to surrounding neighbours, and masks them across the entire clip.

To use Smart Defect Fixer:

1. Install the plugin and apply it as an effect to your footage layer.
2. In the Effect Controls panel, click Analyse Frame. The plugin scans the current frame for pixel outliers.
3. Review the detected defects in the viewer. Adjust the detection threshold to exclude normal colour variation while catching the dead pixel.
4. Click Apply to All Frames. The plugin processes the full clip.

Smart Defect Fixer is particularly effective for hot pixels (bright coloured dots) where the automatic threshold detection reliably identifies the defect. Manual clone stamp is more precise for subtle dead pixels that the plugin may not detect automatically.

Sensor dead pixels are at a fixed position on the sensor — but if your footage includes camera movement (pan, tilt, handheld shake), the dead pixel appears to move slightly in frame due to image stabilisation or warping applied in post. In most cases, sensor dead pixels stay close to a fixed screen position even with camera movement, so the static clone method above works.

If the dead pixel appears to drift across frames due to stabilisation processing, use the After Effects tracker to follow the pixel position:

1. Create a null object (Layer > New > Null Object).
2. Open the Tracker panel (Window > Tracker) and click Track Motion. Set the track point on a distinctive feature near the dead pixel.
3. Track forward through the clip. Apply the tracking data to the null object.
4. Parent your clone stamp Solid layer to the null object. The clone position now follows the tracked movement, keeping it aligned with the dead pixel across all frames.

For complex shots, the Mocha AE plugin (included with After Effects) provides more robust planar tracking than the built-in tracker and handles after effects dead pixel correction on footage with significant camera movement.

The clone stamp solid layer method adds minimal render overhead. Smart Defect Fixer adds more processing per frame — for 4K footage, expect render times roughly 1.5–2× longer than unprocessed output.

Export settings: use the original codec and colour space of your source footage to avoid generational quality loss. If you are delivering to a DaVinci Resolve pipeline, see the DaVinci Resolve dead pixel fix guide — handling the fix at the Resolve stage rather than pre-rendering from After Effects preserves the full RAW or camera-log data.

For archival footage fixes, render to a lossless intermediate (ProRes 4444, DNxHR HQX) rather than H.264/H.265, which introduces compression artefacts that may interact with the cloned area.
