Help With Codec To improve picture

[karimmaster101]

Hi everyone , I Have simple question for you because I new to VLC (just today And I love it sooooo much)

My question is >>> can I use video codec to improve quality of video which i watch with VLC because before VLC I was use JETAUDIO and (nvidea pure video codec) to improve video quality.

So Is there any additional codec to improve quality of video.

Thank you very much
