Hello, I wanted to share this screencast with you. Duration: 1'29'' at 25x speed.
http://lilypond.es/lilypond/timelapse-screencast/timelapse-aquaplane.webm also available as http://lilypond.es/lilypond/timelapse-screencast/timelapse-aquaplane.mp4 It shows trial and error, browsing manuals, pauses for lunch and more. The webm version plays directly on Firefox when drag&drop from file manager in my system. It is a full-screen capture at 1024x600. I used the following console commands in an Acer Aspire One under Debian Wheezy: #mkdir png # save X11 screen @1fps to Ogg Theora; stop with Ctrl+C avconv -f x11grab -r 1 -s 1024x600 -i :0.0 out.ogv # convert to png images ffmpeg -i out.ogv -r 1 -f image2 png/frame%05d.png # Optionally at this point, delete unwanted png's and rename all numerically. # convert images to video @25fps ffmpeg -r 25 -i png/frame%05d.png -r 25 timelapse.mp4 # same for webm VP8 ffmpeg -r 25 -i png/frame%05d.png -vcodec libvpx -r 25 -b10000k timelapse.webm There is much room for improving, so suggestions are appreciated.
