Time Lapse videos are those videos that show a rose blooming in a few seconds, or a city with cars passing fast and clouds moving in the sky at high speed. Anyone can produce a good Time Lapse video, using simple techniques, applications, and programs for the task.
How to Create a Time Lapse Video?
There are two ways to generate the acceleration effect displayed in these videos.
The first is recording a normal video. Once recorded, you can play it quickly, generating another video as a result. One of the problems with this technique is that too much memory is taken up to store the various recording times needed to create a Time Lapse video. After all, every second of a Time Lapse video needs at least 30 seconds of original recording, from which only a few frames are taken advantage of. Even if you use your phone or computer memory well , the files are too large. Another problem is that the quality of the final video is limited to the quality of the original video.
How to take photos for Time Lapse?
The part of taking the photos can be solved with the application a Time Lapse application , available in the Play Store, App Store, and Microsoft Store. I tested an app on Android and made the video below from the photos I took with this app.
The Tina Time Lapse, which I used in the video, allowed me to set the time between the photos, the resolution and the number of photos that will be captured. There is also geotaging option and auto focus, but neither worked well on my Motorola Milestone. After setting up, simply position the phone and click the “Record” button. Photos were taken considering the configured interval, and all of them were saved in a folder called Tina TimeLapse, in the memory of the device.
How to create a time lapse video in Linux?
I created the video in Linux, copying all the photos to a directory and executing the command below:
mencoder “mf: //*.jpg” -mf fps = 15 -o myvideo.avi -ovc lavc -lavcopts vcodec = msmpeg4v2: vbitrate = 15000
In this command I specified 15 frames per second, but other values can be tested and the result will depend on the interval between the takes. See the first video I made to test the technology.
In the Motorola Milestone, as hard as I tried, I could not take one photo per second. Tina TimeLapse set to 1 second managed to get 27 photos in 1 minute. But even then it was enough to make the video. It is interesting to test other applications, and make some videos with changes in the weather, urban scenarios, images from your window. It is also worth using applications and photo montages in the cell phone to compose your time lapse.
