22 Jan Timelapse Toolkit FAQ
No, Timelapse tk is a timing utilty for use in tandem with your camera of choice.
There are four values you can change to match your needs, split into two sections.
Those sections are Input and Output, and both contain a Frames Per Second / Seconds Per Frame and a duration (in seconds) field.
These fields are connected, so changing one field will change the values in the other fields. For example, changing the input duration will automatically increase the output duration in real time.
Yes, just hold down the button for a few seconds and the rate of change will speed up. You can change the rate of change in the Settings screen of your iPhone.
SPF stands for Seconds Per Frame, which is how we measure traditional still image timelapses. So, for example, you might take a picture every 10 seconds, which is 10 SPF. For timing purposes in the app, it doesn’t matter how long each exposure is.
FPS stands for Frames Per Second, which is the measure used in “under-cranked” video timelapses. 24 FPS is the standard in movie theatres, for example.
There are two main ways to create a timelapse; the traditional still image method, where you take a picture every X seconds, and a method called “under-cranking”, which is a video taken at less than the normal frames per second (FPS) rate. The Timelapse TK app supports both methods, though your camera may not. Most cameras can do the first method though they may need an external timelapse trigger, but only a few consumer cameras can do the under-cranking method. The Magic Lantern firmware for Canon DSLRs adds this functionality to the Canon range, while many professional video cameras provide it as standard (for example the Sony FS100)
For under-cranking, FPS is the important measurement, and for the still image method the app uses Seconds per frame (SPF.) For example, the standard rate for film projection in your local cinema is 24 FPS. To under-crank the video you are recording, you would lower the frames per second below that 24 FPS rate, and then play it back at 24 FPS. The term under-cranking itself comes from the days when movie film cameras were hand-cranked, so the operator controlled the speed at which film passed across the lens. That’s why so the action in many of the really early films seemed to be speeded up, because the operator wasn’t cranking the camera fast enough.
You can choose between the two different modes by clicking the button on the bottom left of the screen, the icons are shown on the left of this page.
On the iPhone app, click the icon shown to bring you to the menu screen. On the iPad app, click the icon shown to slide the main screen down, revealing the menu buttons.
Open the menu, and hit the History button. You will see a list of the timelapses you’ve timed, ordered with the newest first.
Click a timelapse entry to open the full details of that timelapse. If you authorised the app to access your location when you first ran the app, you’ll also see a map with the location of the timelapse pinned. The map is the full interactive Google version, so you will need to have cell or wifi service to view the map.
You can delete the timelapse entry using the Delete button at the bottom of the screen.
To load the exact same settings you used in that historical timelapse, click the Load button at the bottom of the screen. This will bring you back to the main timer screen, with those historical settings in place.
On the iPhone app, there’s also a Home button that will bring all the way back to the main Timer screen, without needing to back through the previous screens.
If you encounter a issue in the app, go to the menu and hit the Report Bug button. You can also use the form below.
