Transcode is the word I'd use for the format conversion.  B-)

I run get_iplayer on Raspberry-Pi and the bit rate shown during transcoding 
a HD download is normally around 2500kbits/sec which I have always taken to 
be the bitrate of the resultant stream. It also reports a "fps" which 
normally has value of around a couple of 100. If the bit rate was that of 
the conversion it would be an awful lot higher than 2.5 Mbps...

What does happen is that after a while the line grows 1 character longer due 
to a count going from 999 to 1000+. This then forces the terminal onto a new 
line, so you end up with this report scrolling up the screen rather than 
over printing the existing one.
