Glitter

Hi all, I am trying to animate a fly through but am getting this glittering/jerky effect, any ideas why?
I have tried to attach the video clip but can not for some reason.

I could probably help you if you can upload a blend file.

Hi Asano, trying to find out why I can not attatch files.

I hope if you go here, your problem will be solved
