How to Shoot a Time-Lapse

A time-lapse takes a slow change — clouds drifting, a sunset fading, stars wheeling overhead, a street filling with people — and speeds it up until you can watch hours pass in a few seconds. The technique itself is simple: you take many still photos at a set interval, then play them back in sequence as video. Everything that makes a time-lapse look good comes down to a handful of decisions — how long to wait between frames, how to lock your settings so the brightness doesn’t flicker, and a little bit of math to work out how many frames you need. This guide walks through all of it in plain terms.

What a time-lapse actually is

Strip away the jargon and a time-lapse is just a stack of still photos shown quickly, one after another, so that motion which happens too slowly to notice in real time becomes obvious. Your eye can’t see a cloud move, but line up 300 photos taken a few seconds apart and that same cloud races across the sky. The final output is a video file, which means everything you already know about frame rate and resolution applies to the result — the frames are stills, but the finished clip plays like any other movie. Because the change you’re capturing is gradual, the camera does almost nothing for long stretches; the skill is in the setup, not in the moment.

The gear you need

The list is short, but each item matters. First and most important is a rock-steady tripod. A time-lapse relies on hundreds of frames lining up almost perfectly, and the smallest shift — a nudge, a gust of wind, a soft surface settling under the legs — shows up as a jump in the final video. Set the legs firmly, and if it’s windy, hang your bag from the center column to add weight; our roundup of the best camera tripods covers what to look for in something stable enough for the job.

Second, you need an intervalometer— the thing that fires the shutter automatically at a fixed interval. Many cameras have one built into the menu, often labelled as a time-lapse or interval-shooting mode, and some will assemble the finished movie for you in camera. If yours doesn’t, an inexpensive external remote plugs in and does the same job. Finally, plan for the long haul: plenty of battery and card space. A time-lapse can run for an hour or more and burn through hundreds of exposures, so a full battery (or a grip with a second one) and a large, fast memory card keep the sequence from dying halfway through.

Choosing an interval

The interval — the gap between frames — is the single decision that sets how fast time flies in your final clip, and it depends entirely on how quickly your subject is moving. The faster the change in front of you, the shorter the gap should be so the motion stays smooth rather than jerky. As a working guide, use roughly 1 to 3 seconds for fast-moving clouds or a busy street, 5 to 10 seconds for a slow sunset, and 20 to 40 seconds for the night sky and stars, which crawl across the frame over hours.

These are starting points, not rules. If the change looks too quick and stuttery when you review it, you waited too long between frames; if it looks like nothing is happening, shorten the interval. The safest habit is to shoot a short test — thirty seconds or so of frames — and preview it before committing to the full run. That small check saves you from standing around for an hour only to find the interval was wrong.

Shoot in manual to stop flicker

This is the setting that separates a smooth time-lapse from a distracting one. Shoot in full manual exposure, and set your white balance and focus to manual as well. The reason is simple: in any automatic mode, the camera re-meters every single frame, and tiny frame-to-frame differences in exposure or color turn into an ugly flicker when the stills play back as video. Locking everything down means each frame is captured with identical settings, so the brightness and color stay rock-steady across the whole sequence. If manual exposure is new to you, our how to use manual mode guide walks through setting aperture, shutter, and ISO by hand.

For image quality, shoot RAW or high-quality JPEG. RAW gives you the most room to correct exposure and white balance later, which is helpful across a long sequence, though it eats card space and takes more time to process. High-quality JPEG is lighter and lets many cameras build the movie in-camera. Either works; the non-negotiable part is keeping the exposure, white balance, and focus fixed so nothing shifts between frames.

The frame math

A little arithmetic tells you exactly how many photos to take and how long you’ll be shooting. The core formula is: final length = number of frames divided by output frame rate. So if you want a 10-second clip and you’re outputting at 30 frames per second, you need 300 frames (10 × 30). Want 20 seconds at 30 fps? That’s 600 frames. Because a time-lapse is a video output in the end, the frame rate you choose — commonly 24, 25, or 30 fps — feeds straight into this math; our best camera settings for video guide covers how frame rate shapes the final clip.

Once you know the frame count, multiply it by your interval to find your shooting time. Those same 300 frames at a 3-second interval mean 900 seconds of shooting — about 15 minutes standing at the camera. Bump the interval to 10 seconds for a sunset and the same 300 frames now take 50 minutes. This is why a slow subject with a long interval commits you to a long session, and why it pays to work out the numbers before you start rather than guessing and running short. Always capture a few extra frames beyond the minimum so you have room to trim the beginning and end.

Shutter speed and motion blur

Here’s a subtle touch that makes a time-lapse look cinematic rather than choppy: keep the shutter speed a little slower than you might for a normal still. A slightly longer exposure lets each frame gather a small amount of motion blur, so a moving car or a drifting cloud smears gently within the frame instead of freezing sharp. When those slightly-blurred frames play back in sequence, the movement flows from one to the next and the whole clip feels smooth. Frames that are all frozen-sharp can look strobed and jittery by comparison.

You can’t drag the shutter forever — it has to be comfortably shorter than your interval so the camera finishes each exposure with time to spare before the next one fires. In bright daylight, getting a slow enough shutter often means adding a neutral density filter to cut the light, the same tool used for long exposures; our long exposure photography guide covers that after-dark and motion side of things in more depth.

Advanced: holy grail and hyperlapse

Two techniques go beyond the basic locked-off time-lapse. The first is the holy grail: a day-to-night (or night-to-day) transition where the scene changes from bright daylight to dark night within a single sequence. The challenge is that a fixed manual exposure can’t handle that enormous swing in light, so you have to gradually adjust the exposure through the shoot — slowly and smoothly enough that the frames still blend without flicker. It’s a demanding shot that rewards practice and often some careful work in software afterward.

The second is the hyperlapse, where you deliberately move the camera a small, consistent distance between each frame — walking it forward a step, sliding it along a rail — so the final clip appears to fly through space as well as time. It breaks the usual rule of never touching the tripod, and it demands care to keep the movement even and a fixed point aligned in the frame. Both techniques build on the same foundations of interval, manual exposure, and frame math; they just add a moving part.

Assembling the clip and common mistakes

Once the frames are captured, they have to become a video. The easy route is a camera that outputs a finished movie in-camera— you walk away with a ready clip. The flexible route is to import the stills into software and assemble them there, which lets you set the exact frame rate, fine-tune exposure across the sequence, and iron out any residual flicker. Either way, the stills are your negatives; keep them until you’re happy with the render.

A handful of mistakes account for most failed time-lapses. Using an interval that’s too short for a long event leaves you with far more frames than you can use, or a clip that ends before the event does. A dead battery or full cardcuts the sequence off partway — the reason to start full on both. Exposure flicker from auto modes ruins the smoothness, which is exactly why you lock everything to manual. And bumping the tripod mid-sequence throws the frames out of alignment, so set it firmly and keep your hands off once it starts.

The short version

A time-lapse is many stills shot at a set interval and played back as video. Put the camera on a rock-steady tripod, use the built-in intervalometer or an external remote, and start with a full battery and a big card. Match the interval to the subject — 1 to 3 seconds for fast clouds or a street, 5 to 10 for a sunset, 20 to 40 for stars. Lock exposure, white balance, and focus to manual so the brightness doesn’t flicker, and shoot RAW or high-quality JPEG. Do the math — frames divided by frame rate is your clip length — and keep the shutter a touch slow for pleasing motion blur. Then let the camera build the movie or assemble the stills in software, and above all, don’t bump the tripod.
