Video Render Time
Estimate export duration for a video from its length and render speed.
About Video Render Time
Dividing clip duration by how many minutes of footage encode each minute gives total render time, optionally repeated for multi-pass exports. Long renders up a schedule, so estimating export duration before queueing encodes lets editors plan delivery and overnight jobs.
Formula
Video Render Time
Render time = video length / render speed x passes
- render speed
- Minutes of footage output per minute of render time
Worked example
With the default values below, Video Render Time returns Render Time of 20.0. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Video Render Time calculated?
Render time = video length / render speed x passes Dividing clip duration by how many minutes of footage encode each minute gives total render time, optionally repeated for multi-pass exports.
Why does Video Render Time matter?
Long renders up a schedule, so estimating export duration before queueing encodes lets editors plan delivery and overnight jobs.
What values do I need to enter?
This calculator takes 3 inputs: Video length, Render speed, Passes. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
