Here is one more old timelapse which I love very much. The nimbus
clouds forming distant storm is mesmerizing sight to watch. Due to such
patterns of nature, I love monsoon season whole heartedly. So how
did I capture this? You need some experience of watching the sky
especially during monsoon season. The whitish nimbus clouds
illuminated by Sunlight turn dark as they shadow the sunlight. Such
scenes are normal in coastal Karnataka and occur frequently during
monsoon season. My curiosity towards monsoon makes me to watch at sky
most of the times during monsoon season. Consequently this was one such
scene which I could capture it as timelapse. The final video is edited
in KDENLIVE for various parameters which I dont remember now. I aspire
to capture more such timelapses during monsoon season. Hope you enjoy
the timelapse.
The
movements are achieved by usual cropping techniques. A little bit of
boring math for cropping. The initial plane of frame was as shown in
dotted line and final frame I wanted to achieve is shown as solid
rectangle. Note that I wanted to maintain the the aspect ratio intact
(which was 3:2). If not, the final frames would be clipped and video
looks erroneous! The resolution 550D has is 5184x3456 pixels which is
aspect ratio of 3:2. The motion time lapser counts (0,0) axis from top
left and hence some offset corrections needs to be done to achieve
movement. Consequently I fixed (x,y) co-ordinates to (0,1000) and later
move the plane towards (1500, 0). To achieve this and fit the images to
frame the offset correction goes as below
Frame length: (5184-1500),(3456-1000) = (3684,2456)
Movements from (0,1000) to (1500,0) with frame length of (3684, 2456).
Despite of this calculation, I had some clippings in last few images. May be algorithm used by Motion Time Lapser is different and hence I restricted final 'y' co-ordinates to (1500,200). The final math goes as
Initial (x,y)=(0,1000)
Final (x,y)=(1500,200)
Frame length=(3684,2456)
The final figure is as below. So what's the rule? There is no rule as such! It is upto your discretion to decide the co-ordinates to align with desired movements and speediness. Draw your desired movements on sheet of paper, execute simple math and set the co-ordinates in motion timelapser software which can be downloaded from here
