Default [Q] Extremely Low Video and Audio Quality !?!

Hello everyone.

I Have Google Nexus 4 with stock Android 4.4.2.

My problem is when i use the video recorder ( i have tried stock and LgCamera app both ) the video and audio quaility is extremely horrible. I notice that when i record with LgCamera app at 20mbps, there is a little bit improvement at video quality but the sound is still really bad even tho i record at 48KHZ, 320kbps !

İs there any cure for this. Audio quality really sucks !
