"Scene 42, take three, mark." A wooden board snaps shut in front of the lens and disappears before the actor speaks. In the edit, weeks later, that one second tells the editor which take this is and where the sound lines up with the picture. The second assistant camera holds that board. The role is also called clapper loader.

What a second assistant camera does

The 2nd AC works for the first assistant camera and supports the whole camera team. They help with the camera prep in pre-production and work every shooting day.

The name comes from the days of film. The loader put the film stock into the magazines. Today cameras record to memory cards, so the 2nd AC hands full cards to the digital imaging technician and gets empty ones back. They also write the camera report, a record of every take with lens, settings and notes, which the editor and the post team rely on later.

Responsibilities

  • Slate each take with the clapperboard, so picture and sound can be matched
  • Write the camera reports with take numbers, lenses and settings
  • Manage memory cards and hand them safely to the DIT
  • Place marks for actors on the floor
  • Keep batteries charged and the camera cart organised
  • Move and set up camera kit between set-ups
  • Keep track of the camera package and its paperwork with the 1st AC

How the role touches the budget

No budget responsibility, and little influence on cost. The 2nd AC often keeps the camera inventory and expendables (consumables such as tape, batteries and cleaning supplies), so they may raise small orders or petty cash claims. Their own pay is a day or weekly rate with overtime on timesheets. Missing or damaged kit they report can become an insurance claim.

How people get into the role

Most 2nd ACs start as camera trainee or camera department runner, often after film school or after work on short films. The job teaches the camera department from the ground up, and the usual next step is focus puller. Being organised and calm under pressure counts as much as technical knowledge.

On smaller productions

On low-budget films and documentaries the 2nd AC may also do the work of a data wrangler (copying and backing up the footage) when there is no DIT. On large films there can be several 2nd ACs, one per camera, plus a dedicated loader.
