Understanding Time Lapse Video
A video is a sequence of pictures stitched together to create the impression of motion. Most videos run at 24–30 frames per second, which means a 5-second video at 15 fps contains 75 frames.
Time-lapse video is an observation tool that researchers use to record, review, and analyse user behaviour or actions in specific scenarios. This time lapse method can be combined with interviews, guided tours, or task analysis to study user interactions with prototypes, digital products, or physical services.
The equipment required usually includes a camera, tripod, and remote. Many smartphones also support time-lapse recording. The setup can be used across multiple users in one scenario or across multiple scenarios for the same user group. In cases where researcher presence may affect behaviour, the recording can be set up in advance and reviewed later.
Time Lapse Video vs. Stop Motion Video
Time-lapse and stop-motion are often confused, but they are different. Time-lapse captures a scene at regular intervals, while stop-motion captures frames at irregular intervals to create movement manually. In other words, a stop-motion sequence is not simply a time frame video played faster.
Advantages of Time Lapse Video
1. Large sample sizes
Time-lapse videos can be recorded for many individuals or scenarios at the same time, depending on equipment availability.
2. Time-compressed analysis
Long observations—over hours or days—can be condensed into a few minutes for faster review.
3. No researcher influence
When recorded independently, user behaviour is less likely to be affected by researcher presence.
4. Missed details can be revisited
Researchers can review footage later to capture details missed during live observation.
Challenges of Time Lapse Video
1. Time-consuming and costly
Recording, reviewing, and analysing footage takes time, and equipment or participant costs can increase.
2. No probing
If the researcher is absent during recording, interesting actions cannot be explored in the moment.
3. Support method, not primary
Time-lapse works best as a supporting method. On its own, it may not provide enough depth for a complete study.
