How to Use This Calculator
  1. Enter Start Frame, End Frame, and Frame Rate.
  2. Set Exposure (1=Ones, 2=Twos, 3=Threes).
  3. Review the Total Drawings result.
  4. Use In-Betweens and Breakdown Drawings to inform your decision.

What each input means

Start Frame
Frame number of the first keyframe.
End Frame
Frame number of the second keyframe.
Frame Rate
Animation frame rate.
Exposure (1=Ones, 2=Twos, 3=Threes)
How many frames each drawing is held (1 = on ones, 2 = on twos).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Start Frame = 1, End Frame = 24, Frame Rate = 24, Exposure (1=Ones, 2=Twos, 3=Threes) = 2 = 4 input(s) provided
  2. Calculate Total Drawings
    Total Drawings
    12 = 12
  3. Calculate In-Betweens
    In-Betweens
    11 = 11
  4. Calculate Breakdown Drawings
    Breakdown Drawings
    4 = 4
