All I made, after some testings, increase almost all values regarding to camera quality(encoder decoder audio video and image), and set it up as high as Note 3. The results are good, as I saw.
I doubled the audio quality from 128kbs to 256 kbps for all resolutions. High resolution is up to 288kbps
Increased video bitrate
Increased image bitrate
I able support to wmv and wma
I set estero channel to recording for all resolutions
Increased back and front camera values
And many more goodies I don't remember
Increased a little bit more bitrate values according to video
increased a little bit image quality. I think it's the max possible, but I keep trying to increasing it, to see any difference.
Increased audio quality to 320kbps
added different FPS mod versions
--This is version #1 because I didn't increase all the low values. I installed it in my own phone, and everything is working superb.
Next release I will try to set it higher, as S5 and see what happens, if it's working or not. But by now we have achieve something good.--
Here are some previews: here you can see a little differences regarding to standard values vs. increased ones. Using HDR - strong. Stock Note 2 camera! I realize that after made the modifications the pic is more weighty. I hope you can see the difference in the previews, because I have to low the quality to upload it faster, in tinypic. Sorry.

I didn't test the flashable zip, I only moved the file to "/system/etc" using root explorer and setting permissions, but you tell me.
The idea brings to my head, after testing S5 camera. When you open camera you can see an image super clear and in a higher quality, but when you take a pic, the quality was lower.
