K&F DJI Osmo Pocket 3 Magnetic Blue Streak Filter

Anamorphic streak filter, stretches highlights into a horizontal flare.

A streak filter has a cylindrical element set into the glass that stretches point lights into a long horizontal flare — the same effect anamorphic lenses produce. Headlights, street lamps and reflections off a bonnet get that cinematic line across the frame, with no anamorphic glass required.

The filter clips onto the Osmo Pocket 3 magnetically and lets the gimbal keep working — it does not affect stabilisation. The blue streak across point lights shows on the screen while filming, so the shot can be built around it.
