FLICKERfree Calculator vs RED Tools

The Cinematography Electronics FLICKERfree Calculator is a handy tool to calculate the proper camera speed and shutter angle combinations for FLICKERfree film or digital cinematography. It is especially useful when using HMI or fluorescent lighting. Our FLICKERfree Calculator is designed with the same simplicity as our popular HMI Flickerfree Filming Speeds reference cards. Our App calculates the camera speed in Frames Per Second (fps) and camera Shutter Angle in Degrees. The colors on the calculator, Burgundy (50 Hz) or Blue (60 Hz), also match the colors on our reference cards. Features: * Easy to use with an attractive interface. * Selectable Line Frequency, either 50 Hz or 60 Hz. * Calculates the camera speed in Frames Per Second (fps). * Calculates the camera Shutter Angle in Degrees. * Calculates instantly when an entry is changed. * A finger slider allows user to select the Frames Per Second or Shutter Angle values. * Images of our HMI Flickerfree Filming Speeds reference cards are included. * Optimized for the iPhone 4 Retina screen.

RED Tools is a convenient reference tool designed for use by filmmakers and camera operators to outline best practices in camera set-up for a variety of shooting situations. Each tool is customizable based on a selected RED camera and sensor type. Standard film formats are also included for comparison. RED Tools is also included in the RED Control app, which also provides free, full-featured camera control and video streaming for RED’s latest DSMC3 products. TOOLS INCLUDED: CROP FACTOR Preview how a given focal length will appear depending on resolution setting and sensor type. Illustration depicts viewable area relative to a traditional 35 mm stills photography sensor by default, but other reference sensors are selectable within the drop-down menu. R3D RECORDING TIME Evaluate the video data rate and available recording time based on your RED camera settings. This can help you understand media requirements and production costs in advance of a shoot. FLICKER FREE VIDEO Find a flicker-free shutter speed and frame rate combination when shooting under artificial lighting. DEPTH OF FIELD Understand how various camera settings influence depth of field. PANNING SPEED Estimate the panning speed where judder will likely become too pronounced. The goal is to provide a more accessible tool than the charts and tables commonly referenced in cinematography manuals. It uses the standard rule of thumb that camera panning should not cause objects to transit the entire horizontal extent of an image in any less than seven seconds. EXPOSURE Assist with exposure when one camera setting has to change. Example usage scenarios include when a higher frame rate needs to be used for slow motion, when the T-stop has to change for depth of field, or when the shutter angle has to change to minimize flickering in artificial light. NIKKOR Z Lens Coverage Use this tool to understand how NIKKOR Z lenses will look on your RED Z Mount camera bodies. The tool shows the extent the light will fall off at different sensor formats, and if any hard vignetting occurs.
