1000fps/focus on an EX-FC100?

[BrianEX-FC100]

hi, 1st post... I wonder if you could help with macro and 1000fps/420fps vids on my Casio EX-FC100

I am trying to film some bees gathering pollen from my flowers and would like to use 1000fps or 420fps to capture the bees hovering and the wing movement.

When I shoot the vid I set the camera to macro focus and choose 1000fps.

Before pressing record vid I half press the still shutter control to hopefully focus the camera and then press the vid button to start and stop shooting. ( the image seems to degrade visibly in the rear screen and the quality is lost when playing back or viewing on the tv).

Am I missing something or isnt it possible to use macro focusing with high frames per sec video?

(btw the macro is fantastic for still photos)

Thanks for any help.
