# Definitive Guide to Timelapse and Hyperlapse Intervals
The difference between an amateur high-speed video and a cinematic timelapse mathematically lies in one single factor: the interval. This calculator removes the guesswork, allowing you to precisely plan your intervalometer shot to capture sunrises, urban traffic, or the Milky Way with perfect fluidity.# Recommended Intervals Table (Cheat Sheet)
Use this quick reference table to set your intervalometer according to the subject. The goal is to capture enough movement to be perceptible but smooth.| Subject / Scene | Suggested Interval | Event Duration (Minimum) |
|---|---|---|
| Fast Clouds / Storms | 1 - 2 seconds | 20 - 30 min |
| Urban Traffic / People (Blur) | 0.5 - 2 seconds | 15 - 20 min |
| Sunset / Sunrise (Holy Grail) | 5 - 10 seconds | 1.5 - 2.5 hours |
| Slow Clouds / Shadows | 10 - 15 seconds | 2 - 3 hours |
| Stars / Milky Way (Astro) | 15 - 30 seconds* | 3 - 5 hours |
| Construction / Fast Plants | 5 - 15 minutes | Days / Weeks |
Note for Astro
The interval is usually dictated by the exposure time needed to capture light (500 rule) + 1 or 2 seconds of buffer for card writing.# The 180° Rule (Motion Blur)
A common mistake in timelapse is getting a "jittery" or staccato (strobing) video. To get that smooth cinematic look, you need motion blur.The Rule
Your Shutter Speed should be half of your interval.
Example: If you shoot every 4 seconds, your exposure should be 2 seconds. This fills the "temporal gap" between photos, creating trails in cars and soft water.

# Flicker and Manual Aperture
"Flicker" is the annoying flickering caused by micro-variations in the diaphragm aperture between shots.- Lens Twist: Slightly unlock the lens on DSLRs to break the electronic connection and fix the aperture mechanically.
- All Manual: ISO, White Balance, and Focus must be fixed. Never use automatic modes.
- Shoot in RAW: Essential for correcting exposure and color in post-production without destroying the image.
Advanced Technique: The "Holy Grail"
The "Holy Grail" refers to the smooth transition from day to night (or vice versa). It is the most difficult technical challenge because light changes drastically (up to 15 stops of aperture).
