It would be unrealistic to expect Richard Crowley to
understand Motion Estimation and Deblocking. He gets
hung-up on his phobia of the lossyness of temporal
compression, and can never realize that it can be done
well, without the disaster he fears so much.
But he is right, that you can't expect to effectively address
complex technical issues with a simplified interface. You
don't have to be a pro, but you do need to understand the
effect of the "tweaks"/settings. One way to get better
performance from the default settings, is to pay more for
the program.
You also might consider that there is not a lot of
commercial incentive to develop such a program, at least
not for any major player. Not with the law suites from
the movie industry.
You could break up what you want into separate
processes and acquire a better encoding program like
TMPGEnc 4.0 XPress, which goes to some lengths to
make the process a little easier. But that wouldn't be the
integrated software you seem to be asking for. (Generally
speaking the more integrated; the less technically capable
the parts.)
Luck;
Ken
