I hope I'm not stating the bleedin' obvious here (if I am, tough!
), but when you look back at yourself after filming, you may see exaggerated bad bits.
The reason is that when conciously dancing in front of a camera, and especially in a studio type setup, you may not be performing at your best - i.e. no atmosphere etc, to encourage you to 'immerse yourself in the music.
I found that I could instantly recognise obvious faults such as stoooping, but I was also picking things out that I thought were really ugly, when perhaps they weren't quite as bad when just I was just enjoying the dance on the social floor....if that makes sense?
