So how do I read the bitrate of the RM file going in so that I do not unintentionally upsize the bitrate and create an unnecessarily large .flv result? I will say, however, that some of the other RMs I've converted had high bit rates to begin with, but still resulted in extra-large flvs. Thanks.

How come the Flash file becomes so huge after converting the RealMedia? The video and audio quality are just fine but the file bloat is crazy, like 3-8x's the size of the original.

If you tell mencoder to encode with a bitrate that is 3-8x's than that of the original, you will get files that are that much bigger as well.

Even an 18Kb test file gets blown up to 94Kb. I have attached the output for that particular conversion, as it is very representative of the larger files I'm working with.

This is my argument string: -of lavf -oac mp3lame -lameopts abr:br=56 -srate 22050 -ovc lavc -lavcopts vcodec=flv:vbitrate=300:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -vf scale=320:240

[...]

...

Video stream: 226.209 kbit/s (28276 B/s) size: 75403 bytes 2.667 secs 30 frames

Audio stream: 52.088 kbit/s (6510 B/s) size: 20750 bytes 3.187 secs

Well, and the file is still ca. 25% _smaller_ than the size _you_ told mencoder to create.
