Hello Bernhard
I will double check, I must say for convenience I am using a Packman /
Suse rpm.
Therefore they may use a release version rather than a CVS one.
I am probably missing on that one.
Hopefully yes, because it will mean that my question was already
obsolete when I asked it :-[

yuvdenoise is a bit of a complicated beast I don't think it'd be easy
to optimise.
A simple multithreaded optimisation technique is to use slices (less

It seems to be yuvden
The simple solution to worrying about the need to optimise the code
for your cpu is to look at the output from top.
(I am actually interested in seeing the %CPU each of your processes
take up.)
Are both your CPUs fully loaded?
Yes - multi threading is not needed but you could always optimise

I think that is moderate to mild filtering. I think the '-V' and
'-v' could be safely increased to 2 but that's not critical.
