Frame Rate Calculator
This calculator helps you determine the frame rate (frames per second, FPS) of a video or animation, given the duration of a single frame and the total number of frames. Understanding frame rate is crucial for video production, animation, and gaming, as it directly impacts the smoothness of motion and the perceived quality of the visual output. A higher frame rate generally results in smoother motion, while a lower frame rate can be used for stylistic effects or to reduce file size and processing power requirements.
function calculateFrameRate() {
var frameDuration = document.getElementById("frameDuration").value;
var totalFrames = document.getElementById("totalFrames").value;
var resultElement = document.getElementById("result");
// Clear previous results
resultElement.innerHTML = "";
// Validate inputs
if (isNaN(frameDuration) || frameDuration <= 0) {
resultElement.innerHTML = "Please enter a valid positive number for the duration of one frame.";
return;
}
if (isNaN(totalFrames) || totalFrames <= 0) {
resultElement.innerHTML = "Please enter a valid positive number for the total number of frames.";
return;
}
// Calculation: Frame Rate (FPS) = Total Frames / Total Duration
// Total Duration = Frame Duration * Total Frames
// Alternatively, Frame Rate = 1 / Frame Duration (if only frame duration is known)
// Using the provided inputs:
var frameRate = parseFloat(totalFrames) / parseFloat(frameDuration);
// Display the result
resultElement.innerHTML = "
Result:
" +
"Frame Rate:
" + frameRate.toFixed(2) + " FPS" +
"This means that " + frameRate.toFixed(2) + " frames are displayed every second.";
