The info you provide was not enough to provide any detailed help.
How you extract higher quality JPEG images when using nemcoder? Is it
using lavc internal encoder?

If for whatever reason nemcoder works in your specific scenario does not mean
that ffmpeg result is worse.

So far I have not found that fieldmatch + decimate gives poor results
and I assume
its working perfectly.

Otherwise there is tracker for bug reports where bug once reported
have higher chance to be fixed.
