What is the Speed---Quality slider for ?
Would it be OK to use 100% Quality ?
Speed - Quality ?
I would certainly be OK, although kind of overkill.
I have seen repeated posts on several places on the net that beyond 95% is not recommended because you almost never reach 100% (except for stills, where you reach it extremely quick) but the program will try until time-out to do it, so you get the maximum allowed computing time for each frame.
On the other hand the quality difference for settings above 0.95 are said to be undiscernable in an image of TV size.
In general, above the default 70% setting, the return of the extra time diminishes rapidly.
If you don't care how long it takes (I do renderings at night, so what if it finishes at 3am instead of 1am ?), then you slightly improve quality when you slide the cursor right, up to a point.
You only have to be aware that above 95% you are practically losing time and electricity.

At high-speed settings, the MPEG encoder doesn't spend as much time making calculations, so the encoding (compression) process goes faster. At high-quality settings, the MPEG encoder takes it's time and tries to do a better job.What is the Speed---Quality slider for ?
MPEG compression is lossy. You always loose some data. The hard part is trying to figure-out which data to throw-out and how to make the best use of the remaining data. It becomes more difficult at low bitrates, because more data is thrown-away at low bitrates.
You can have two MPEGs with the same bitrate, but if one was encoded with a professional multi-pass encoder, it will have better quality than one encoded with a home-hobbyist encoder.
