Plan a timelapse that fits your edit
Plan a timelapse from the length you want to show. Work out the frame count and interval, then check power, storage and exposure before the shoot.
A timelapse is easier to plan when you know the role it will play in the finished edit. It might show changing light, people moving through a place or the transition between two parts of a trip.
Start with the desired playback length, then calculate the capture needed. Do not assume a long recording session automatically creates a useful sequence.
Work backward from the finished seconds
For twenty seconds of playback at thirty frames per second, you need six hundred frames. At an interval of two seconds, six hundred complete intervals require twenty minutes of capture.
Use the timelapse calculator to change the inputs. It counts completed intervals conservatively. Some cameras also capture a frame at the start, so their count can differ by one without either calculation being mysterious.
Choose an interval for what is changing
The interval determines how far the subject can move between frames. A very long interval may make fast movement jump, while a very short interval can create more files than the intended result needs.
Make a small test of the actual subject. A setting that suits slowly changing light may not suit busy pedestrians or rapidly moving clouds. Judge the resulting movement rather than selecting a number solely because it appears in someone else's example.
Leave time for the camera to work
An interval must accommodate exposure and any file writing or processing. A planned two-second interval cannot be assumed to work with a three-second exposure. Check the camera's actual behaviour and supported mode.
Keep exposure changes deliberate. Automatic shifts can produce an uneven look, but locking a setting without considering changing light can create a different problem. The appropriate choice depends on the session and the capabilities of the camera.
Plan the practical limits separately
Check available storage, power, weather and physical stability. For drone capture, use supported functions and comply with the relevant operating constraints. This article does not provide a flight authorization or a battery-duration guarantee.
Do not turn a calculated twenty-minute session into an assumption that an aircraft can safely remain in position for that long. Mathematical playback planning and safe capture are different questions.
Place the result with a purpose
A timelapse can make a transition visible, but it does not have to appear simply because you recorded one. Test its place in the sequence and trim it to what the story needs.
