How to Set Up a Long-Term Time-lapse

In this article, we will give you a quick introduction to long-term timelapse. First of all, what is a long-term timelapse? We describe long-term timelapse as a filming project that requires the camera to be unmanned, in a special housing, needing an external power source, and lasting for several days, months, or years. Skyshot has set up over 250 time-lapse cameras in the last 10 years, so we are specialists in this field. So here are some tips on long-term time-lapse project setups.

1. Specialized Timelapse Camera

Long-Term Timelapse requires specialized timelapse camera equipment. Several options are available in the market, like the Brinno, a custom-built CCTV camera, and Titan X.

We have done a comparison video on these 3 options. The link is available below. The basic functions are the same; they will trigger the camera at regular intervals. They can be powered by a power source that can last for months & years. However, more advanced timelapse systems like the Titan X will allow you to view your images online on a secured server. And it alerts you if the system is down. That’s the beauty of Titan X. These 2 features remove every photographer's biggest fear of long-term timelapse – losing your images.

Whatever system you choose, we will advise against the DIY route. This is because once the timelapse camera is fixed, any camera movement will change picture framing and affect the timelapse video. So, there is no turning back if your DIY camera is not working. Therefore, we highly recommend using the Tbox Titan X. The Titan series has gone through many years of refinement by our team. We have completed 100s of timelapse projects that last for years with this system, and our users worldwide have benefited from it too. So, you know you are getting reliability, which is the most critical factor in a successful long-term timelapse project.

2. Entry-level DSLR camera

Many photographers assume that shooting with a high-end DSLR and lens will provide the best picture quality. Yes, that is true, but do you really want to lock up a $4000 DSLR in a timelapse system lasting several years? From our experience, an entry-level DSLR camera with 20 megapixels will do the trick. This will provide you with a 6K-size video resolution, which is more than sufficient for most clients.

3. Shooting Format

Many photographers make the mistake of filming long-term timelapse in RAW format. Although RAW gives you the best-quality images, it is overkill. You will need lots of data storage space to store many terabytes of data, not to mention the heavy post-production work that will be needed. So, to keep the project manageable, our recommendation will be 16 to 24 mega-pixels at fine jpeg settings. This will keep the file size around 4MP per image.

4. Setting the interval

The first thing to remember is that 25 photographs, when compiled, will make 1 second of timelapse video. So knowing the duration of your project and understanding the client's needs will determine the interval setting. Most clients will want to have monthly reports where the stakeholders watch, say, 1 minute of timelapse video. For 95% of the building construction projects, a shooting interval of 10 to 15 minutes per shot is recommended. This is the sweet spot when you consider 2 opposing factors; data space management and the smooth transition. Shooting closer intervals will give you a smoother transition from frame to frame but produce lots of data. Conversely, having wider intervals beyond 15 minutes per shot will create a choppy timelapse caused by flickering. This is largely due to changes in lighting conditions caused by cloud cover and the sun moving across from east to west during the day.

Time-lapse camera installation for engineering & construction sites requires safety documentations & certifications.

5. Where to install the camera

Here are some things to consider when installing a camera

a. Is it site accessible

b. Where is the power source

c. Where is the sun's direction if you are installing a solar panel? Is there enough sunlight at the location

d. There are other risks, like high winds and lightning strikes as well. Not to mention working at height and other safety considerations

Finding the optimal location & proper installation is crucial

6. Securing the timelapse camera & Solar panel

A stable mounting ensures a smooth time-lapse movie. Most timelapse cameras are placed on higher ground to get a vantage view of the project site. It is imperative that the mounting is stable to counter the elements like high wind and rain. If you are using a solar panel to power the camera, it is good practice to mount the panel away from the camera with a separate mount. This is because solar panels have big surface areas acting like wind sails. They will cause the camera to shake if it shares the same mounting in close proximity to the camera.

7. Plan for regular site visits

If your timelapse camera does not have remote monitoring options, ensure you have budgeted for regular site visits. For long-term timelapse lasting several years for building construction, we visit our cameras every 2 weeks to a month. This will ensure that if your camera fails, the amount of data lost is insignificant compared to the actual progress on site. Our Titan X has a remote monitoring function that allows you to see the most updated images online. It also has an alert function if the system is down. For these reasons, we don’t need to make site visits monthly. That is the beauty of Titan X.

8. Dealing with Timelapse Flicker

For long-term timelapse, photos are taken at regular intervals throughout the day, across different lighting conditions and human activities on site. In one photo, a large crane is on-site. In the next photo, taken 15 minutes later, the crane has moved to another location. There are considerable changes in every photo. So when all the images are stitched together, and the timeline is compressed, it is like watching a strobe light, or what we photographers will call – a timelapse flicker.

As mentioned earlier, one way to deal with flickering is to reduce the timelapse interval to 10 to 15 mins. Having the camera exposure metering set to center-weight or evaluative will also help to reduce the flickering as the camera takes an exposure reading from a large area, reducing the chance of a wrong exposure reading that you can get from a spot metering. For more information on camera settings, please check out our video on the best camera settings for long-term timelapse.

However, most of the flickering reduction must be done in post-production. There are several software available in the market specially designed for creating timelapse. We use LR Timelapse. It provides the most comprehensive solution for time-lapse editing, keyframing, grading, and rendering.
