Create timelapse movie from shaked photos

The problem consist of creating a timelapse made of photos which have been taken with a camera which has been removed and attached to a tripod during a few months thus creating a lot of shaking. Solution, use hugin to align photos:

#!/bin/bash
 
align_image_stack -v -a$1 -s 2 *.jpg
 
mkdir base
for i in $(find . -maxdepth 1 -name "*.tif"); do n=".$(echo $i | cut -f2 -d".").jpg"; convert $i $n && mv $n base; done
rm *.tif
cd base && mencoder -nosound -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell:autoaspect:vqscale=3 -mf type=jpeg:fps=5 mf://*.jpg -o $1.avi && cd .. && mv base/$1.avi .

Shadow

At first it was just a rumor. Have you seen it? I did not believe it. No, it is not true I said, there was nothing. Then a few night passed. This time I saw it myself. A shadow in the dark, very fast, seemed to have disappeared into the wall as the eye blinked. Then, the next night, I saw it again, clearly. I followed the shadow and saw the crack in the window, the missing fragment of glass and behind, more blackness. Finally I saw it in daylight. It was unmistakable now. There is a cat living in the basement somewhere.

Shadow, the cat

Timelapse videos

To create timelapse videos as the one in the previous post or this one here are some simple steps:

1. connect the camera (Canon 450d in my case) to the computer and turn it on

2. unmount it if it’s mounted automaticaly

3. run the following script (timelapse.sh) to capture images to the computer:

#!/bin/bash
 
for i in $(seq 900); do
   no=$(printf "%04d" $i)
   gphoto2 --capture-image-and-download --filename="timelapse-$no.jpg"
   sleep 15s;
done

You can adjust the number of images or the sleep interval.

4. combine the images at 10fps to create time-lapse.avi

mencoder -nosound -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell:autoaspect:vqscale=3 -vf scale=1980:1080 -mf type=jpeg:fps=10 mf://*.jpg -o time-lapse.avi

5. experiment & enjoy
