Help on Imovie 0'9

Hi,,
I'm using Macbook pro , and I'm using Imovie 0'9 to do my graduation project ..
My project is depends on Video with timer to analysis equations ( I want to take a video and and let the speed of video as much as low so got more frames this part is done but the second part which is the time i couldn't find it ) ,
However, i need the Time appear's on video while I'm running it as full screen
as ( HH:MM:SS:FF, where H: hours , M: min's , S: seconds , and F is Frames
-where Frames is best part to me- ).

and if Imovie does't support this feature. the time i mean
could u tell me a program is compatible with my Mac do these features

Thank you
