Choose between „Fast“ and „Accurate“. „Fast“ has equal performance in CPU and GPU version. „Accurate“ detects a wider range of faces but should only used in GPU mode due to expensive computation.

Buffer Size

The higher the Buffer Size value, the smaller faces can be detected in the current frame. Higher buffer size also leads to longer computation time. Depending on the footages resolution, GPU mode may not be able to run due to shortage of GPU memory (you’ll get a notification in this case).

Samples (new in v1.1)

A number between 1 and 64 defines how often the position of all faces shall be computed and averaged (which can give smoother detections). This has a bigger performance impact and higher should only be used when necessary.

Two passes (new in v1.1)

Run an additional detection pass for every face. This helps smoothing alot (especially for small faces) and can be enable by default. Masking Tab

Exclude largest faces

Faces are sorted by size and the n largest faces wont become blurred. This can be useful if e.g. you want to blur faces only in the background of a subject.

Include Masks / Exclude Masks / Additional Masks

This is a system which gives you granular control over which areas to blur. Pressing one of the „Add“ buttons will add a corresponding mask.

Include Masks

Faces inside an include mask will become blurred by the plugin.

Exclude Masks

Faces inside an exclude mask won’t become blurred. This is evaluated after the include masks.

Additional Masks

An additional masks can be used to define faces which were not recognized by the plugin.

Tipp: Control the influence of the masks with the inbuild “mask opacity” slider. If value is greater than 0% mask will be used.

Modes & Scaling Tab


You can choose between „Face“ and „Eyes“, which will position the mask accordingly.

Use rotation

If enabled, the face mask will follow the rotation of the face.

Scaling & Expanding

Use those sliders to define size and expansion of the masks. This is applied relative to the masks size. Appearance Tab


The style which is used for mask drawing. Try them :)


Applies to „Solid Rectangle“ and „Outline“ style and defines the effects color.


Used by „Outline“ and „Mosaic“ style and defines the lines width and accordingly the number of mosaic tiles.

Effect on transparent

Use this to draw the effect result on a transparent canvas. This way you can use control other layers effects, e.g. a blur layer, with the detections. Premiere Pro version

The Premiere Pro version has some differences with the After Effects version.

Deactivate effect for previews

Keep this activated for smoother preview and timeline scrubbing. Only deactivate when needed. Masking

Sadly, the masking workflow in Premiere Pro is very limited and therefore Blace offers a (restricted) workaround compared to the After Effects version. You can use the Midpoint, Width and Height sliders to define an area, which either serves as include or as exclude mask (switch with „Type“ field). To visualize the mask, enable „Draw mask“ (and disable it for rendering). We hope to provide a better workaround in the future!
