Time Lapse Video - 1 [Dose Making]

This is my first time lapse video. It is not something like fastening up the video but taking images at intervals and rendering them as video. The images have to be very much steady to have better time-lapse video. It is good to use a tripod, make adjustments and start taking pictures.

So how did I do it? I own Canon SX 210IS. Using CHDK available for canon cameras, I used intervalometer script which captures the images at pre-defined rate without user intervention.  I am not writing on CHDK. Please refer links below for details.  The images were taken at the rate of 1-image per 2sec. So I captured around 69 images and put them up in KDENLIVE to create a video. Since I did not have tripod, the video came out bit shaky. Kindly bare with it :-). Next time I will take better one.

A simple slideshow creation in KDENLIVE will do the rest. I created slideshow with 3 frame drops   with 29.97fps and 720 progressive scan rate. I am not sure about the exact calculation of frame drops. If you are interested please refer wikipedia entry on SMPTE timecode (see references below).

Enjoy the short time-lapse video of Dose making. Of course I heated the Dose for long time to have
better detail [put the gas in sim :-)]. I am optimist of posting such videos often [That is why the title numbered 1 :-)].
