Render Time from Frame Rate Calculator
A render job's length comes down to how many frames you have and how long each frame takes. The frame count is the clip duration multiplied by the frame rate. Enter your clip length, frame rate, the average seconds to render one frame, and the number of parallel render nodes, and this tool returns the total frame count and the estimated render time on one machine and across your nodes.
Render time formula
Total frames = clip seconds * frame rate
Single-machine seconds = total frames * seconds per frame
Parallel seconds = single-machine seconds / render nodes
Hours = seconds / 3,600
Parallel time assumes frames divide evenly across nodes with no overhead, so it is a best-case figure. Real wall-clock time is usually a little higher due to scheduling and asset loading.
Worked example
A 60-second clip at 24 fps has 60 times 24 = 1,440 frames. At 30 seconds per frame that is 1,440 times 30 = 43,200 seconds, or 12 hours on one machine. Spread over 4 render nodes the parallel time is 12 divided by 4 = 3 hours.
Render time: frequently asked questions
How do you calculate total render time?
First find the number of frames: clip length in seconds times frame rate in frames per second. Then multiply that frame count by the average time to render one frame. Total render time = clip seconds times fps times seconds per frame.
What frame rate should I use?
Use the project's delivery frame rate. Common values are 24 fps for film, 25 fps for PAL video, 30 fps for NTSC-style video and 60 fps for high-frame-rate or game capture. Enter whatever your timeline is set to.
How do I find my per-frame render time?
Render a short test segment and divide its wall-clock render time by the number of frames it contained. Enter that average here. Per-frame time depends heavily on scene complexity, resolution, sampling and hardware, so it is a measured input rather than a fixed figure.
Does using a render farm change the result?
Yes. If you split the job across multiple machines or GPUs that render in parallel, divide the single-machine total by the number of parallel render nodes for an approximate wall-clock time. Enter the node count to see that estimate.
Sources and notes
- The calculation is plain arithmetic: frames equal duration times frame rate, and time equals frames times per-frame render time.
- Per-frame render time is a measured input from your own test render; it is not a fixed published figure.
