The Fundamentals
What is a Hyperlapse Step Size?
A milky way exposure calculator is a tool that computes the maximum safe shutter speed before stars begin to trail visibly on your camera’s sensor. It takes your specific camera body, lens focal length, aperture, and the area of sky you’re pointing at – and outputs the longest exposure you can use while keeping stars as sharp points of light rather than elongated streaks.
The key word is specific. A milky way exposure calculator that only asks for focal length is applying the 500 rule – a formula derived from 35mm film that has no awareness of how many megapixels your sensor has. A proper calculator uses the NPF rule, which factors in pixel pitch: the physical size of each photosite on your sensor. On a 61MP Sony A7R V, each pixel is roughly half the physical size of a pixel on a 12MP Sony A7S III. The 500 rule treats both cameras identically. The NPF rule does not.
This calculator uses the NPF rule. Enter your camera – or select it from the preset list – and it computes your pixel pitch automatically. No manual calculations. No spec sheet required.
The two ways to use this calculator
Most photographers start with a route and want to know how far to step. Enter your total distance in Step Size Mode and the calculator tells you exactly how far to move between every frame. If you prefer to decide on a comfortable step size first and work backwards to how long a route you need, switch to Route Length Mode. Enter your target step size and the same formula solves in reverse.

The Hyperlapse Step Size Formula
Step Too Large
Steps over 1 metre produce footage where the camera appears to teleport between positions rather than glide. Stabilisation and warp tools in Premiere or Resolve cannot fix this — it is a capture error. If your step size comes back over 1 metre, extend your route, shorten the clip, or increase the FPS.
Step Too Small
Steps under 5 centimetres cannot be reproduced accurately without physical markers at every position. At this scale, tiny variations in camera placement become visible as jitter. If your result is this small, your route is too short — extend it or reduce your target clip length.
The Sweet Spot
For smooth, professional foot hyperlapses, aim for 10–50 centimetres (4–20 inches) per frame. One natural walking step is approximately 65–75 centimetres, so the ideal range is roughly a shuffle to a confident half-step. The calculator shows a live status indicator so you can see instantly whether you’re in the green zone.
The two ways to use this calculator
| Step Size | Movement | Field Rating |
|---|---|---|
| Under 5 cm / 2 in | Barely a shuffle | Mark every position — not reliable otherwise |
| 5–10 cm / 2–4 in | Small shuffle | Ground markers required |
| 10–50 cm / 4–20 in | Shuffle to half-step | ✓ Ideal range |
| 50–100 cm / 20–40 in | One walking step | Test pacing 5× before rolling |
| Over 100 cm / 40 in | Large stride | Avoid — spatial strobing in final clip |
Step-by-Step Guide
How to Use the Calculator
Step 1 — Choose your calculation mode
Use Step Size Mode if you have a specific route in mind. Use Route Length Mode if you have a comfortable step size in mind and want to know how far to walk — useful for planning routes on unfamiliar locations before you arrive.
Step 2 — Enter your distance or step size
In Step Size Mode, enter the total length of your route in metres or feet. In Route Length Mode, enter your target step size in centimetres or inches — the sweet spot is 10–50 cm (4–20 in). The unit system auto-detects from your browser locale; override it with the Metric/Imperial toggle if needed.
Step 3 — Set your video specs
Enter your final clip length and frame rate. 24 fps gives a cinematic look; 30 fps suits digital platforms. For stock footage on Pond5 and Shutterstock, 15–20 seconds at 24 fps is the commercial standard.
Step 4 — Set your interval
This does not change your step size — it only drives the total shoot time output so you can plan against golden hour windows, permit durations, or battery life. Use 2 seconds as a starting point for most foot hyperlapses.
Step 5 — Read the highlighted result and status indicator
The coloured dot tells you instantly whether your step size is in the ideal range, borderline, or too extreme to produce usable footage. Green means go; orange means test carefully first; red means revise your route or video specs.
Step 6 — Tick off the Before You Shoot checklistv
The checklist appears automatically after calculation with your specific values filled in — shutter speed, step distance, interval setting. Work through it before pressing record. It takes 90 seconds and prevents the most common causes of wasted sequences.
Before You Shoot
The Field Checklist — Built Into the Calculator
Every time you calculate a result, a personalised Before You Shoot checklist appears below it. Each item is populated with your actual values — your specific shutter speed, your step distance, your interval setting, your total shoot time. Tick items off as you prepare; ticked items strike through to keep your place.
The five items that matter most on a foot hyperlapse shoot, in the order you should do them:
1. Manual mode locked. Every auto setting — aperture, ISO, shutter, white balance — will cause exposure flicker between frames. Lock them all before the first frame fires.
2. Shutter speed set by the 180° rule. Your shutter speed should be half your interval. At a 2-second interval, use a 1-second shutter. In daylight, use an ND filter to achieve this — the ND Filter Calculator finds your exact filter strength.
3. Ground marked. For steps under 30 cm, physical markers at every position are not optional. For larger steps, walk the distance 5 times to build muscle memory before rolling.
4. Intervalometer tested. Fire the intervalometer and watch the first 3 frames actually capture before starting your walk. A misconfigured trigger at frame 1 means nothing to recover in post.
5. Spare power packed. Total shoot time displayed in the results — add 30% for setup and positioning between shots.
Frequently Asked Questions
What is a hyperlapse step calculator?
A hyperlapse step calculator is a browser-based tool that computes the exact distance to move a camera between each frame of a walking hyperlapse. It works in two modes: Step Size Mode takes a route distance and returns how far to step between shots; Route Length Mode takes a target step size and returns how long a route you need to walk. Both modes use the same core formula: step size equals total distance divided by the product of clip length and frame rate.
What is the ideal step size for a walking hyperlapse?
The ideal step size for a smooth, professional walking hyperlapse is between 10 centimetres and 50 centimetres (4–20 inches) per frame. Steps in this range are physically reproducible, produce smooth camera motion that stabilisation software handles cleanly, and work across a range of focal lengths. Steps over 1 metre (40 inches) create visible spatial jumps that cannot be corrected in post-production. Steps under 5 centimetres (2 inches) are too small to reproduce accurately without physical ground markers at every position.
How do I calculate hyperlapse step size manually?
The formula is: Step Size = Total Distance ÷ (Clip Length in seconds × Frame Rate). For example, a 60-metre route for a 15-second clip at 30 fps: 60 ÷ (15 × 30) = 60 ÷ 450 = 0.133 metres = 13.3 cm per frame. To solve in reverse (Route Length Mode): Route = Step Size × (Clip Length × FPS). A 20 cm step for a 20-second clip at 24 fps: 0.20 × (20 × 24) = 0.20 × 480 = 96 metres.
I know my step size — how do I find out how long a route I need?
Use Route Length Mode in this calculator. Enter your target step size in centimetres or inches, set your desired clip length and frame rate, and the calculator outputs the exact route distance you need to walk. This is useful for scouting a location in advance: calculate the required route length at home, then open maps to find a path that fits. A 25 cm step for a 15-second clip at 24 fps requires a 90-metre route.
How do I mark my steps accurately during a foot hyperlapse?
For steps under 30 cm, physical markers are necessary — chalk on pavement, small stones, or tape at each position. For steps between 30–70 cm, experienced shooters can use a consistent half-step or single stride and muscle-memorise the distance by walking it 5 times before rolling. For any step size, always do a short test sequence of 10–15 frames before committing to the full route — play it back before you start to verify smoothness.
What shutter speed should I use for a walking hyperlapse?
Set your shutter speed to half your interval — this is the 180-degree rule. At a 2-second interval, use a 1-second shutter. At a 3-second interval, use 1.5 seconds. In daylight, these long exposures require ND filters to prevent overexposure. Use the free ND Filter Calculator to find the exact filter strength for your scene, aperture, and ISO.
What is the difference between a hyperlapse and a timelapse?
A timelapse is shot with a completely stationary camera — only time is compressed, space does not change. A hyperlapse moves the camera between frames, compressing both time and space simultaneously. The Timelapse Interval Calculator handles the stationary case; this calculator handles the moving case. For a drone hyperlapse, replace total route distance with the total flight path length your drone will cover.
Can I use this for drone hyperlapses?
Yes. In Step Size Mode, enter the total flight path length the drone will cover as your distance. The step size output becomes the distance the drone should travel between each frame. For manual drone hyperlapse workflows, pair this with the Timelapse Interval Calculator to also calculate the time interval between shots based on your drone’s flight speed.
Why does step size matter more than any other hyperlapse setting?
Step size is the only variable in a foot hyperlapse that cannot be corrected after the fact. A wrong interval affects timing but can be adjusted in the edit. Wrong exposure can be recovered from RAW. An inconsistent or oversized step produces spatial jumps between frames that warp stabiliser, optical flow, and every other post-processing tool treats as an unsolvable discontinuity. Getting the step size right before rolling is the single highest-leverage action a hyperlapse photographer can take.
