Pls help me understand B, I & P frames and psy-rd

DISCLAIMER: I'm a Newbie; please bear with me...

1. I've read and read and read, but I still don't understand B frames, I frames or P frames.

One site advised using as many B frames as possible because they're inherently good somehow (how, IDK).

Another site said not to use too many B frames because they result in a less sharp picture.

What are the differences between these frame types, and what is a good number of B frames to use when decoding with, say, HandBrake? (That doesn't result in a less-sharp picture.)

2. What is "psy-rd" and what is a good setting? I hear the settings are very fussy and you can get a fuzzy, less sharp picture unless you use psy-rd...just...right...

3. Does the very latest H.264 support psy-rdo, and what the heck is it? What are good settings?

4. Reference frames: the more the better?

5. Does anyone know the H.264 instruction for "verbose logging"? I've tried v=1, vb=1, verbose=1, verboselog=1, verboselogging=1 in HandBrake, but the Activity Window always says unrecognized instruction -- every time.

Sorry for so many questions.

Any help is appreciated.

Thanks,

Kerry
