NewLapse

This replaces chronolapse on linux

Usage

newlapse -capture -rate 10 -folder "recording"
newlapse -crop -folder "recording"
newlapse -convert -fps 20

You can also do the following

newlapse -ccc -rate 5 -fps 10 -folder "tmp"

which will capture a picture of the screen every 5 seconds, and save it in the ./tmp folder. if you CTRL+C it will start cropping the pictures and convert each screen into a mp4 file.

On a mac with retina display you will need to write a config file. First you have to figure out how big the screencapture pictures are. In my case 2800x1800. Then you echo "2800x1800+0+0" > config.txt". When cropping you just provide newlapse -crop -config "config.txt".
