Exciting stuff!
 
Here's our new paper on creating time-lapse videos from Internet photos that will appear in SIGGRAPH 2015!

Project website: 
http://grail.cs.washington.edu/projects/timelapse/

Abstract:
We introduce an approach for synthesizing time-lapse videos of popular landmarks from large community photo collections. The approach is completely automated and leverages the vast quantity of photos available online. First, we cluster 86 million photos into landmarks and popular viewpoints. Then, we sort the photos by date and warp each photo onto a common viewpoint. Finally, we stabilize the appearance of the sequence to compensate for lighting effects and minimize flicker. Our resulting time-lapses show diverse changes in the world's most popular sites, like glaciers shrinking, skyscrapers being constructed, and waterfalls changing course.

Longest time lapse yet with 5 hours in a minute (×300 speed). Watch out for kids building a snow fort :)

My second time lapse is a little more interesting than the first, showing the view outside my window at the MPI. It sums up half an hour in a minute (30× speed).

Thank you )
For that timelapse I have used the diaphragm priority mode of my camera. So, only the exposure time was adjusting to the changing light conditions. But, I still had "flickering" on the 17-th second of the video.
If you shoot timelaps at daytime, the best choice will be to use fully manual mode of a camera, with fixed exposure time (longer then 1/30 sec). It will help to reduce flickering.
Another option to handle the exposure changes is to post-process the timelapse sequence in Lightroom, applying the automatic exposure to all of the images.
The freely licensed music is usually present in the youtube clips. If the used music is not free, youtube usually blocks the clip. I have used the SoundHound App to find out the name of interesting music from another timelapse videos on youtube, and downloaded it from the web. The same trick works with the free radio www.di.fm

Sweet animations
Starting this month Verizon FiOS customers can get upload speeds every bit as fast as their download speeds. Since that means faster, easier sharing of high-res illustrations, designs, and photos, FiOS is sponsoring a series of posts on Colossal to help us commission and share these super hi-res ani

An interesting graph taken from [1], Google's research on what different strategies experts and non-experts take to stay secure online. Biggest difference: experts use unique passwords and password managers, non-experts rely on anti-virus software.

It's interesting to see the effect of a partial solar eclipse that darkens the sun by about 3 quarters at its peak. Taken in Saarbrücken on 20 Mar 2015.

My very first (very short) time lapse shows the build-up of snow over an hour. Each second covers half an hour of real time. If you look carefully, you’ll see the tree on the left getting weighed down by snow, and a bit of snow accumulating at the bottom. Not spectacular, but a start :)
