Thanks John, I'm wading through the material.
A lot of this information is PE-Pro oriented, but I can see the value in it.
I was hoping my providing the file info and the target info might narrow the field a bit. Many rendering articles start out with "It depends..." and then generalize from there.

So very much will depend directly on what the JW Player will take, and what it works best with.
Do you have the published specs. of that player?
Getting quality vs file size is mostly science, but also some "black art." Quality is determined by Bit-Rate. Once that has been established, then Duration, plus Bit-Rate, will determine file size.
The variable in the above will be the CODEC, as some allow higher perceived quality, at lower Bit-Rates.
For instance, if the display medium will allow for DivX, then one is likely to get good quality, for a set Duration, as DivX will allow lower Bit-Rates. However, not knowing the JW Player, I cannot just recommend DivX, as it might not work. At this point, it gets down to "what works."
This is from the tech spec URL:

Thank you for that link, and the CODEC chart.
DivX does not appear, that I could find, so let's immediately rule it out.
H.264 is a very good format, in that it allows good quality, at lower Bit-Rates. I would look to it. Some Bit-Rate experimentation might be needed, to find a workable combo of quality vs file size, but that is where I would begin looking. Either the standard MP4, or MOV wrappers w/ the H.264 CODEC should work with that player. With the Audio, I would go with the MP3 (MPEG - Layer 3) CODEC.
Thank you Bill
I have an aditional question; in Pre9.0.1 I've not stumbled upon a way to pick the wrapper, I just have to experiment and see what pops out.
Some are intuitive (like AVI) but others - not so obvious. Am I missing somethng?
