Video blur tool

Video blur tool is a batch-capable processor that obscures sensitive regions in video frames to support privacy, legal compliance, and editorial safety. It accepts common video formats, applies configurable blur to user-specified regions, and preserves motion continuity to avoid artifacts. Users can rely on auto face detection to identify faces for blurring, or supply manual region coordinates derived from frame dimensions. Blur methods include Gaussian and mosaic, with intensity controls that scale to the target resolution. The tool operates as a processing backend, producing a new video file that retains audio and timing when desired, and emits a concise processing log for auditing.

Processing workflow follows a deterministic frame-based pipeline. For each frame, the tool maps each region to a blur kernel sized by the intensity parameter and applies the selected method. Auto-detected faces are grouped into bounding boxes and tracked across adjacent frames to reduce jitter, while manual regions are applied frame-by-frame or with simple region tracking if enabled. The output maintains the original color space and temporal resolution, with encoding settings selected by the user. This enables content teams to redact people, license plates, or confidential materials quickly, reducing post-production time and lowering re-edit risk.

Unique value lies in combining auto detection with precise region targeting and batch processing, plus explicit handling of edge cases like partial occlusions and out-of-bounds coordinates. It supports localization for common video standards and provides clear error reporting for missing inputs or incompatible formats.
