Last week we introduced Timelapse, a photography technique which creates fast motion videos in which, for instance, clouds race across the sky or a city transforms from night to day in just a few seconds. This week we’ll divulge how to argument this technique to the next level – the Hyperlapse!
Remember that during a Timelapse the camera should remain completely stationary to avoid a shaky video? But what if we were to actually move the camera perfectly horizontally around a fixed object during a Timelapse? This is exactly what a Hyperlapse is! Although this can be achieved with an expensive Dolly-Rig setup, it can also be done using a tripod, mathematics and some patience!
Firstly decide which object (say a building, stationary person) in your frame will serve as the reference point (the point in which the resulting Hyperlapse will move around). Secondly decide how long you would like the resulting video to be, and how many frames per second it should have. Thus for film, a 3 second, 24 fps video would need 3*24 = 72 shots. Thirdly, decide how far the camera should move for every shot. If there is some limit to the total distance the camera can move (for example along a 100 meter bridge), then the formula to calculate the distance the camera must move for every shot is:
It is crucial that that you use the same distance to move the camera for every shot, otherwise a shaky Hyperlapse will be created.
Lastly, for both Timelapse and Hyperlapse one of the biggest issues you’ll face is flickering which occurs when the camera automatically chooses the exposure level. Although automatic exposure works quite well for a single shot, as we wish to combining multiple individual shots together, any change in exposure (or brightness) between successive shots causes a jarring flicker. Thus when possible, shoot with a suitable manual exposure level. If necessary, the brightness of the resulting video can then be optimized in Post-Production.
Now that you are sufficiently inspired, why not grab your camera and put this theory into practice! Need a video editor to assemble the video? Download the 30-day demo of Movie Edit Pro or Video Pro X today!
