Yeah, that would work in some situations; of course working out what the
magic number has to be is another issue entirely.  Does cinelerra allow a
fractional frequency to be entered (for example, 48000.0123) and does it
have an upper limit on the precision you can enter?  If it's limited to
integer values it won't be much good on long (>60 minute) clips.

True - which in some workflows could be awkward (or at least require a
lot of repeate trial-and-error before getting things right).

I'll have to look into what sample rate conversion cinelerra uses
in this situation - hopefully it's Erik's "secret rabit code".
