Superman-Five for Fighting

Recently, im trying to investigate a new  software, on how to sync a high details audio to a video file.

The 1st video showing a song that i play by hearing after watching someone play it on youtube.

Superman --  A wonderful creation by Five for Fighting!!                                                                                                       The 1st video taken by using my handphone.  The video was terrible and audio was delayed by 1 second .

The 2nd video taken by recording a video and audio separately and i try to sync both togather using Windows Movie Maker.The great news is i can edit the transition or timeline to what i want, perfectly sync both audio and video togather(although it takes time). But the effect was very dissapointing. Noise appeared throughout the audio....a very sad things.

I get to choose the quality of video that i wans to cre8, but the quality of audio drop when i drag the file into timeline in movie maker. Summore it takes time for the video to completely done ( around 1 day).

Perhaps...i should consider buying a digital video recorder.
