You are neither specifying a bitrate nor constant quality,
the default is 200k which is not possible for the given
resolution. You can speed up encoding by specifying a
constant quality with -qscale 10 (lower is better).
x264 has options to allow faster encoding, filesize will
still be smaller for a given quality than mpeg4.
