Command marking the official start of principal photography on a production. Signals the first shoot day following pre-production.
Technical Details
For film cameras like the Arriflex 35-III, the ramp-up to the correct frame rate of 24 fps takes approximately 0.8 to 1.2 seconds. Digital cinema cameras like the RED V-Raptor reach their target frame rate within 0.15 seconds. The timecode begins with the first fully exposed frame, not the start command. The sound recordist and camera assistant document the exact start time for synchronization in post-production. In multi-camera setups, all cameras must start in sync within 2 frames (83 milliseconds at 24p).
History & Development
The term established itself in the 1920s with the introduction of motor-driven film cameras that required a ramp-up time. Early hand-crank cameras started immediately, but modern systems for the first time required precise timing communication between the director and the camera department. With the introduction of the clapperboard in 1929, "Picture Up" became the standardized announcement before the first clap. Digital cinema from 1999 onwards significantly reduced ramp-up times, but the workflow term remained.
Practical Application in Film
In action sequences in "Mad Max: Fury Road" (2015), cinematographer John Seale coordinated up to eight cameras with precise "Picture Up" timing for explosive stunts. Documentary filmmakers often use rolling record modes, where "Picture Up" marks the point for usable material, not the actual recording start. For Steadicam shots, the camera usually starts 3-5 seconds before the actual action to optimize stabilization and image composition. Timelapse productions define "Picture Up" as the first frame of a programmed sequence, often with minutes of lead time.
Comparison & Alternatives
"Picture Up" differs from "Recording" (continuous recording) and "Speed" (camera reaches target frame rate). "Slate" marks the synchronization point, not the recording start. Modern proxy workflows use "Backup Recording," where low-res material runs concurrently before "Picture Up." Pre-roll functions of digital systems record retroactively 2-8 seconds before the start command, making the classic ramp-up workflow obsolete.
