Blood Hits sind One-Take-Momente. Ich plane Kamerawinkel, Speed und Coverage sorgfältig – der Effekt muss im Kasten sein, bevor wir neu aufbauen können.
Explosive charge with blood bladder rigged to actor's body. SFX tech detonates on cue — performer's physical reaction must happen in the same frame or the impact reads as fake.
What is a Blood Hit?
A Blood Hit (or Bullet Hit) is a practical special effect that simulates a projectile impact on the body. The combination of a squib, blood bag, costume preparation, and coordinated actor reaction creates the convincing effect of a gunshot wound.

Blood Hits remain a core tool for action films. The combination of practical effects and CGI enhancement allows for even more convincing results – but the authentic physical reaction of an actor to a real squib hit has an immediacy that purely digital effects struggle to achieve.
From the crafts
Perspectives
Director
Ein gut ausgeführter Blood Hit ist visceral und schockierend. Die Kombination aus praktischem Effekt und authentischer Darsteller-Reaktion erzeugt echte emotionale Wirkung.
Producer
Blood Hits bedeuten Vorbereitung, Sicherheitschecks und oft mehrere Kostümsätze. Jeder Hit braucht Zeit im Schedule – aber der visuelle Impact ist den Aufwand wert.
