 I'm trying to put together a timelapse video from individual frames, like:

 convert *.jpg output.mp4

 This produces:

 convert: delegate failed `'avconv' -nostdin -v -1 -i '%M%%d.jpg' '%u.%m'
 2> '%u'' @ error/delegate.c/InvokeDelegate/1919.

 The issue is that it wants avconv, but avconv is not available with
 MacPorts.  See here:

 https://superuser.com/questions/568464/how-to-install-libav-avconv-on-osx

 As you can see from the answers, installing avconv is possible if you use
 MacPorts, but is very inconvenient.  Whereas with brew it's trivial.

 There has been an attempt to bring avconv into MacPorts here:

 https://trac.macports.org/ticket/50039

 It was rejected because "it appears that ffmpeg provides all this
 provides".  It seems not.  The current situation leaves ImageMagick in a
 broken state.
