Matt, Andy and I built our Atari Punk Console kits tonight, so that we are ready for Synth Night 2 at Hack Pittsburgh. Hope to see you there! Video encoding deets after the break.

Video encoding notes:
I used my cameras built-in intervalometer to take a photo every 3 seconds. Photos were taken at the lowest resolution/quality available, because it is still much higher than HD video . I used my Nikon D700 with a 40mm lens at ISO 1600, f/8, and 1/500.

To convert the series of stills into a time lapse movie, I used mogrify (the latest version) and mencoder (stock Ubuntu version):

mogrify -resize 1920x1278 -crop 1920x1080+0+50 -rotate 180 -brightness-contrast 18x27 *.JPG
mencoder -ovc xvid -xvidencopts pass=1 -o /dev/null -mf w=1920:h=1080:fps=20:type=jpg 'mf://*.JPG'
mencoder -ovc xvid -xvidencopts pass=2:bitrate=8000 -o apc.avi -mf w=1920:h=1080:fps=20:type=jpg 'mf://*.JPG'

I was pleasantly surprised to note that mogrify automatically used both of my CPU cores for encoding. Mencoder didn’t by default, and I didn’t see any performance gain by adding the option threads=2 to -xvidencops… bummer!
