I am not a media junkie, nor do I have well-informed opinions as to 
which encoding scheme is "best."  But I do know that it is very 
simple to down-scale (lower the frame-rate, bitrate for video or 
bitrate for audio.)  At the same time, a lot depends on how the 
initial flv file was created.  I have found a number of flv files 
that were much smaller before I down-scaled them than before.  The 
flv format has a few oddball things that can be optimized during the 
initial creation of the file which get unoptimized when it is 
reencoded.  Anyway.  I have good success shrinking things to the 
H.263 <http://en.wikipedia.org/wiki/H.263> or MPEG-4 Part 10 
(AVC/H.264) <http://en.wikipedia.org/wiki/H.264>.  Many things that I 
reencoded to those turned out smaller.  But dropping the bitrates and 
framerate seemed to have more impact than just the encoding scheme.
