Video compression and measuring loss of quality is not something with
which I am expert other than the subject analysis of what looks better
or worse to my eyes. I can, for example, use FormatFactory to conver
from FLV to WMV along with choosing if I want high, medium, or low
quality in the WMV output. I can reduce an AVI video down to a small
fraction of its original size when going to WMV low format (and if it
isn't something that needs high resolution or large window size then the
file will be small). Alas, I haven't come across a FLV to WMV
conversion that doesn't sacrifice noticeable quality while trying to
make a very small WMV file (FLV ends up being a lot smaller in file
size).
YouTube lists what filetypes they will accept for video formats. My bet
is that FormatFactory probably supports all of them so you could play
with conversions to see which gives you the smallest file size while
also trying to reduce loss of quality.
