Enter the total number of frames and the duration of the film or video into the calculator to determine the film rate. This calculator can also evaluate any of the variables given the others are known.
Film Rate Formula
The following formula is used to calculate the film rate.
FR = T / F
Variables:
- FR is the film rate (frames per second)
- T is the total number of frames
- F is the duration of the film or video (seconds)
To calculate the film rate, divide the total number of frames by the duration of the film or video. The result is the film rate, expressed in frames per second. This indicates how many frames are displayed per second, with higher rates resulting in smoother motion.
What is a Film Rate?
A film rate, also known as frame rate, refers to the frequency at which consecutive images, known as frames, appear on a display. It is expressed in frames per second (fps). The higher the frame rate, the smoother the motion appears. Different types of media use different frame rates. For example, most films are shot at 24 fps, while television uses either 30 fps (in the US) or 25 fps (in Europe). Video games often aim for a frame rate of 60 fps for smoother and more responsive gameplay.
How to Calculate Film Rate?
The following steps outline how to calculate the Film Rate.
- First, determine the total number of frames (T).
- Next, determine the duration of the film or video (F) in seconds.
- Next, gather the formula from above = FR = T / F.
- Finally, calculate the Film Rate.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
total number of frames (T) = 1500
duration of the film or video (F) = 120 seconds
