Default Possible engine issue,need help to diagnose

Hey guys,
I drive a 2010 G37s coupe 6mt, 64k miles on the odo.
Since I got my car fixed from an accident, it has been behaving weirdly.

Basically, whether I'm in 1st or 2nd gear and I'm accelerating quickly there is this unpleasant sound that erupts.(between 3.5-4.5k rpms) This does not happen in any other gear.
Sounds as if it is coming from my engine or maybe even my transmission. The sounds can be almost described as a finger rubbing on glass,
although much louder. This sound also happens when I am driving through rough roads in 1st or 2nd gear with a heavy foot.

I've been trying to pin point this noise but I have no luck. I've been searching forums everywhere, everyday. It's getting pretty frustrating. Any help or input would be highly appreciated. Thanks in advance!

P.S. I apologize if you cannot hear the sound well from my video, as I realized my phone did not pick up the sound loud enough.
