About

MarKit Pro

Features
Read full description

MarKit Pro is a camera report and shooting order management tool built for film and commercial production teams, especially for shoots that require pre-lighting, blocking, and rehearsal-based planning. During pre-production and on-set preparation, camera departments need to record camera settings, lens choices, camera positions, movement notes, and blocking results for each shot. At the same time, directors, assistant directors, and camera teams need a clear way to align on the shooting order. MarKit Pro brings camera reports and shooting order planning into one iPad-based workflow, reducing the need to manage shot information across spreadsheets, chat threads, and temporary notes. With MarKit Pro, camera teams can efficiently document camera parameters for every shot during blocking and pre-lighting, while also reviewing rehearsal media connected to each shot. This helps the team confirm camera placement, lens decisions, movement plans, and execution details before the actual shoot begins. Each shot is displayed as a movable node on a visual canvas. Users can freely reposition shot nodes, connect multiple shots, and quickly rearrange the shooting order. Compared with traditional spreadsheets, this canvas-based workflow makes it easier to adapt to changing production needs and helps directors, cinematographers, and assistant directors understand the current shooting plan at a glance. MarKit Pro serves as a communication bridge between the camera department, directors, and assistant directors on film and commercial sets. It helps teams organize shot information faster, clarify shooting order more effectively, and maintain a smoother workflow from pre-lighting and blocking through the final shoot.
