I have used this app before, its great... Some artifacting is to be
expected but I would recommend capturing a larger screen size to begin with
(equal or larger than the dimensions of the intended output file) such that
the text is smaller in relation to the dimensions of the screen. Use the
uncompressed 8bit codec or the animation codec (not H264, which is quite
lossy) and make sure that "smoother" video capture is selected in movie
settings... Also, make sure that the codec you choose is not "interlaced"
Choose progressive scan if there is a choice. Also, as mentioned before, you
could apply an anti-alias effect or a slight gaussian blur if the aliasing
is still bothering you.
