Hello Manoj
I did not have any tripod this night so I had to get the fastest shutter speed available without a too strong ISO in order to reduce noise.
1/4 sec was acceptable to me (bstaying still) and also allowed me to get the people movement without erasing it with a longer shutter speed.
So I took a deep breath and waited for the people before shooting without any movement.
A tripod would have been better. In this case I would have taken the same shuter speed but with a better iso and aperture !
Thks for interest !
