Command line time-lapse for OSX with de-flicker.
This is incomplete, but it may be useful.

If you have not already, Install macports.
sudo port install ImageMagick (why they spell it CK I don't know)
sudo port install p5-perlmagick
sudo cpan install File::Type
sudo cpan install Term:ProgressBar
On first run cpan will ask some questions, just press enter to select the defaults.
These commands install the necessary software, and it may take some time. sudo will ask for your system password, you will need administrator privileges.
Once the above software is installed. Put the below script file somewhere where your path can find it. Please remember that I did not write the original script, Vangelis Tasoulas wrote it and I just changed a few things so it would play nice with OSX.
Copy the file there with finder.
chmod +x timelapse-deflicker
add the scripts folder to your profile:
Edit in text edit and add
~/scripts to your path so it looks something like this:
# MacPorts Installer addition on 2012-11-20_at_14:09:39: adding an appropriate PATH variable for use with MacPorts.
# Finished adapting your PATH environment variable for use with MacPorts.
Now navigate to the folder that has your time-lapse images and run
You might like to add the verbose
-v and debug
timelapse-deflicker -v -d
Before you start you might like to read the help file:
-w Choose the rolling average window for luminance smoothing (Default 15)
-p Number of luminance smoothing passes (Default 1)
Sometimes 2 passes might give better results.
Usually you would not want a number higher than 2.
Note the two other options. My understanding is that the default
-w 15 will smooth luminance changes over a half second window. (assuming 30fps).
Navigate to the newley created deflickerd folder.
Now the final step. ffmpeg is a quick and easy way to put images together into a movie.
sudo port install ffmpeg
I compress to prores 422 so it is ready for editing.
ffmpeg -r 30 -f image2 -start_number 1 -i IMG_%04d.JPG -codec:v prores -profile:v 2 bannanasky_deflickered.mov
There are many other ffmpeg options:
