It's a bit of a long shot but often rescaling footage performs an anti-aliasing
function, it depends on what software you use to perform the scaling (but most
put the images thru some anti-aliasing). You could try rescaling your captured
footage up a couple of pixels in both dimensions and then down again using Final
Cut pro or some other editor.
The quality of capturing such software can do does also depend to the graphics
card on the machine and it's refresh rate also (maybe tweak the screen settings,
or do the capture on a machine with another graphics card), as well as to the
way the software itself is working. I've never used snapz pro myself, so I don't
know if there are any other settings other than choosing compression codecs that
could help.

Subject: [Frameworks] Snapz Pro
Frameworkers,
A technical question. My assistant is doing screen captures for the first time,
using Snapz Pro. We're pleased with it, but it seems there's no
one-size-fits-all solution among the numerous compression algorithms one can
choose from.
We're getting the best video captures from the two compressors below, but there
is aliasing when text is panned or when there's rapid motion.
The compressors we're using are Apple Animation and H.264. Both have the
following settings:
654 x472, millions IMA 4:1, mono, audio setting 22.050Khz
frame rate: 30
data rate: 23.35MB
Any advice on how to improve the performance will be much appreciated.
