[Haskell-cafe] Making videos of your project

Is there anyone here with experience in screencasting of text-based
applications, who could offer advice on how to produce screencasts
on windows/xp? The basic screencasting (capture+annotation/editing)
is not the problem, eg, CamStudio seems ok, and Wink gives me
more control for mostly input-driven sessions (where I want
screenshots whenever something useful happens, not long videos of
my mousepointer wavering about the screen;-). Both can generate .swf.

The problem comes when trying to scale down the size to
what would fit in a browser window (what a viewer would see,
without having to scroll around) - text becomes hard to read (quality,
not size) if I scale from 1280x800 to 640x400, and if I try to work
in a screen area that fits 640x400 in the first place (so no scaling
would be needed), I can't really show anything..

The intended topic is still haskellmode for Vim, updating the
old screenshot tour from


so there'd be a gvim window and a browser window (in real
life, also a GHCi window, and quite possibly a cygwin window,
but lets keep it simple), and the most interesting info is not in
graphics, but in the texts, source code, menus, tooltips, ...,
