Usage

sightsnap v0.6 by @monkeydom
usage: sightsnap [options] [output[.jpg|.png]] [options]

Default output filename is signtsnap.jpg - if no extension is given, jpg is used.
If you add directory in front, it will be created.
  -l, --listDevices         List all available video devices and their formats.
  -d, --device <device>     Use this <device>. First partial case-insensitive
                            name match is taken.
  -t, --time <delay[,duration]>Takes a frame every <delay> seconds and saves it as
                            outputfilename-XXXXXXX.jpg continuously. Stops after <duration> seconds if given.
  -z, --startAtZero         Start at frame number 0 and overwrite - otherwise start
                            with next free frame number. Time mode only.
  -m, --mp4                 Also write out a movie as mp4 with the timelapse directly. Time mode only.
  -k, --skipframes <n>      Skips <n> frames before taking a picture. Gives cam
                            warmup time. (default is 2, frames are @6fps)
  -j, --jpegQuality <q>     JPEG image quality from 0.0 to 1.0 (default is 0.8).
  -x, --maxwidth <w>        If image is wider than <w> px, scale it down to fit.
  -y, --maxheight <h>       If image is higher than <h> px, scale it down to fit.
                            When <w> and <h> are given, the camera format used is optimized.
  -p, --timeStamp           Adds a Timestamp to the captured image.
  -o, --onlyOneTimeStamp    Freeze the TimeStamp to the first value for all images.
  -T, --title <text>        Adds <text> to the upper right of the image.
  -C, --comment <text>      Adds <text> to the lower left of the image.
  -f, --fontName <font>     Postscript font name to use. Use FontBook.app->Font Info
                            to find out about the available fonts on your system
                            (default is 'HelveticaNeue-Bold')
  -s, --fontSize <size>     Font size for timestamp in <size> px. (default is 40)
  -h, --help                Shows this help.

To make timelapse videos use ffmpeg like this:
  ffmpeg -i 'sightsnap-%07d.jpg' sightsnap.mp4
To make animated gifs use: 
  ffmpeg -r 10 -i Test3-%07d.jpg -vf 'scale=768:-1' test3.gif

Special consideration: if your texts might start with a '-' then you need to use the alternative syntax. E.g. for the comment area -C='-text that starts with a hyphen'
