Raspi, a webcam and a beautiful day.
I am setting up a raspberry pi to capture the erection of a building going up near my apartment. Today I shot almost a full day's worth before the pi's 8gb SD card filled up stopped recording.
I used a simple bash script to capture a photo, sleep for 5 seconds then capture again. It takes about 5 seconds to take each frame, as it basically turns the camera on and off each time it takes the shot so I get around 1 image every 10 seconds.
I still have a bunch of tweaking to do and will likely run the frames though a deflickering filter for the final video, but for now I am just using ffmpeg to stitch the raw photos into a 60fps video. (the following command)
ffmpeg -r 60 -f image2 -s 1920x1080 -i frame%06d.jpg -vcodec libx264 -crf 25 -pix_fmt yuv420p output-60fps.mp4
I posted the day's results on youtube so you all can take a gander.

Looks really cool. Look forward to see it completed.
It will be one hell of an erection!
I see you found a use for your raspberry pi. If you want it to shoot continuously you should create a network share and have it save images to your local network storage.
