No conflict at all. -E processing is done after the quantization
tables have been used.

Makes a lot of sense. -E goes thru the output of the quantization
process to make it more efficient to encode.

Well, yes. "-K hi-res" is the same as "-H" though so I'm not sure
why you'd want to use both :)
You can, if you wish, create your own custom matrices and use them
with "-K file=path_to_your_file". Thus you can take the intra (I
frame) table from the hi-resolution side and combine that with
the non-Intra (B/P frame) table of TMPGEnc.
I've attached the custom file where I did just that. The I frames
end up being bigger (but there are only on average 2 of those per
second) but the P/B frames become smaller. Overall the image looked
very good (but not having done double blind testing against a default
encoding that's not saying a lot ;)).
