Weather radar animation

Here is a short weather radar animation I made of a 24 hour period last week (24 October 2011) when the east coast of Ireland (Dublin city in particular) was deluged with an exceptionally heavy rain storm.


I made this video clip starting with a directory of individual radar images in PNG format and then used the mencoder tool (part of mplayer) to generate a MP4 video clip from the frames.

mencoder mf://*.png -mf fps=5:type=png -ovc lavc -lavcopts vcodec=mpeg4 -o video.mp4

Note that I've set the frames per second to 5 (fps=5). The usual 24 frames per second is too fast.

Images from Met √Čireann (the Irish Meteorology service).
