Checked examples

Four-machine render

Inputs: 240 frames; 90 s/frame; 4 machines; 80%

Calculation: 240×90÷(4×0.8)

Result: 6,750 seconds = 1.875 hours

Assumes evenly distributed work.

Single machine

Inputs: 100 frames; 60 s/frame; 1 machine; 100%

Calculation: 100×60

Result: 6,000 seconds

Equals serial render work.

Assumptions, rounding, and limits

  • Average seconds per frame is representative.
  • Machines work in parallel.
  • Efficiency includes scheduling/overhead.
  • Setup, retries, storage, licensing, and queue delays are excluded.

Frequently asked questions

Why include efficiency?

Parallel jobs rarely scale perfectly; efficiency provides an explicit adjustment.

Is this a completion guarantee?

No, it is an estimate from supplied averages.

Can frames vary in complexity?

Yes; use a measured representative average and consider scenarios.
