Can you save the A/V settings on a quicktime video?

i have a video i took with my digital camera, but its long and the sound is like a half a second off, but quicktime settings lets me “jog” the audio to the right or left a little and line it up perfect…but everytime i close it and reopen it resets to default! even with the audio settings (bass, treble, etc.) is there a way to tweak the video and KEEP it like that?!?!? thanks!!
