A bash script for os x that makes a timelapse video of your screen with ffmpg.
- Takes incrementally numbered screenshots of your main monitor at a definable interval, and at a definable resolution.
- If you have ffmpeg installed, it will let you render these screenshots to a .mov file at an arbitrary framerate.
- Clone screenlapse.command to wherever you want your screenshots and the video.
- Make the file executable (via cmd-i or chmod +x screenlapse.command).
- Double click it.
If you're in a hurry, just smash the enter key three times to start recording with defaults, otherwise, you can set these parameters:
- Interval: number of seconds between each screenshot. Default is 4.
- Starting value for incremental numbering: if you exited the script before and want to resume now, put the name of the last screenshot +1 here (if your last screenshot was 2214.jpg, enter 2215 here). Default is 1.
- Target width: Whatever you want the width if the resulting images/video to be, i.e "640". Correct aspect ratio is maintained. Defaults to your screen resolution.
You can then stop the screenshotting with ctrl-c. If ffmpeg is installed, you will then be prompted whether you want to render the screenshots into a -mov file. If yes, you will be prompted for:
- Framerate: Target framerate of the .mov. Default is 12.
- Filename: The name of the .mov file. Default is "timelapse".
Careful: screenlapse will overwrite any existing files without warning.
If you have homebrew installed: $ brew install ffmpeg
Otherwise try:
$ svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
$ cd ffmpeg
$ ./configure --enable-shared --disable-mmx
$ sudo make
$ sudo make install
(I could never make this work)
Screenlapse happened because of this blog post, so thanks to those two guys.
