For those who own HoneyComb tablets like myself, you might or might not already know that there's actually a time-lapse video recording feature built into honeycomb's Camera app. Yes you heard that right. Its there. Took me a while to realise it because I don't use the camera app often on my ASUS EEE Pad Transformer other than to shoot pictures but when I used it about few days ago to test the video recording quality, I noticed it has an option for time lapse recording.
Okay so what's time-lapse video recording all about? Here's an explanation from Wikipedia on Time Lapse Photography:
Time-lapse photography is a cinematography technique whereby the frequency at which film frames are captured (the frame rate) is much lower than that which will be used to play the sequence back. When replayed at normal speed, time appears to be moving faster and thus lapsing. For example, an image of a scene may be captured once every second, and then played back at 30 frames per second; the result would be an apparent increase of speed by 30 times. Time-lapse photography can be considered to be the opposite of high speed photography.
So do you get it now? The video in this post which was taken by the latest Samsung Galaxy Nexus which was unveiled about 2 weeks ago in Hong Kong, demonstrates what time lapse photography is all about. In HoneyComb's camera app, you get to choose between the following time lapse intervals: 1s, 1.5s, 2s, 2.5s, 3s, 5s and 10s.
The time lapse intervals means that for every x second(s), a frame will be captured. So for instance, if you set the time lapse interval to 2 seconds - every 2 seconds, 1 frame will be captured. Lets say you leave the camera app turned on to capture a video of the outdoors for 2 minutes. The end result will give you a 2 second video. How that is calculated is simple:
2 (mins) x 60 seconds = 120 seconds
2 seconds time lapse interval x 30 frames per second = 60 seconds
120 seconds / 60 seconds = 2 seconds of video time / event time.
So that's how you calculate how long the end result is. In HoneyComb, this is shown in the app itself, so you don't really need to calculate the time but its good to know how long you should leave the camera on just to have X seconds (or minutes) amount of footage.
With time-lapse recording, you can record events such as the sunset or sunrise or even a flower blossoming and so on. Use your imagination! With that, I will leave you to creatively explore time lapse photography. If you have a HoneyComb tablet, give it a shot.
