FPS Render Time Calculator
Estimate the total render time for an animation from its length, frame rate and time per frame.
How it works
Total frames = length × fps · Total render time = total frames × time per frame
Total render time is just the number of frames multiplied by how long each frame takes. The frame count is the clip length times the frame rate, so raising the frame rate from 24 to 60 fps lifts the frame count — and the render time — by two and a half times for the same footage. The "render vs. playback" ratio shows how far you are from real time; a farm scales this down by rendering many frames at once.
Worked example
A 60-second clip at 24 fps is 1,440 frames. At 8 seconds of render per frame that is 1,440 × 8 = 11,520 seconds, about 3.2 hours — roughly 192× the one-minute playback length.
Frequently asked questions
How does a render farm change this?
A farm renders many frames in parallel, so wall-clock time drops by roughly the number of machines: 1,440 frames across 20 identical nodes finish in about 1/20th of the single-machine time, ignoring queueing and file overhead.
Does frame rate affect render time?
Yes. More frames per second means more frames to render for the same duration. Doubling the frame rate roughly doubles the total render time, assuming each frame costs the same.
Why do some frames take longer than others?
Per-frame time varies with scene complexity — motion blur, depth of field, volumetrics, more visible geometry and lighting bounces all add cost. This calculator uses an average, so busy frames pull the true total above the estimate.
