I need to shoot a 8 hour timelapse tomorow of a production set up for a fashion show. I only have 1 8 GB P2 card. What would be the best format to get maximum time in onto the p2 card??
TimeLapse ?

Something PN, either 30PN or 24PN.
Next decide what interval to use. If you know how long you want the timelapse segment to be, it will be easy to calculate the required interval and recording duration based on the expected setup time and recording framerate.
Since you can record about 20 minutes of PN footage on a single 8GB card, unless you intend to create a timelapse longer than that, the whole thing will fit on one card.
Your next issue will be how to power the camera for the entire duration. You can run it on AC using the charger/AC adapter, or you can switch batteries as needed. Since you don't actually have to shoot continuously, a short power-down to swap batteries should not be noticeable in the timelapse.
Make sure you have a solid tripod so the camera doesn't move. You'll probably want to leave focus on manual, but maybe let the camera handle exposure to deal with changing light levels.

so if i set it for 720p 24pn what should i set the interval too?? Ive never done this before?
Depends on how many frames you will shoot per interval, and how long you want the 8 hour timelapse segment to wind up. Also, would 24PN or 30PN be more appropriate for your delivery format?
I'll give you two examples:
#1: 30PN with a goal of producing a 60 second timelapse of the 8 hour setup
60 seconds * 30fps = 1800 frames needed for the timelapse. Since the production setup takes 8 hours * 60 minutes * 60 seconds * 30fps = 864000 frames, you'll have to drop all but every 864000 / 1800 = 480th frame. At 30fps, every 480th frame means you need to record one frame every 16 seconds.
#2: 24PN with a goal of producing a 30 second timelapse of the 8 hour setup
30 seconds * 24fps = 720 frames needed for the timelapse. Since the production setup takes 8 hours * 60 minutes * 60 seconds * 24fps = 691200 frames. you'll have to drop all but every 691200 / 720 = 960th frame. At 24fps, every 960th frame means you need to record one frame every 40 seconds.
The camera allows you to record more than one frame per interval, and this will obviously impact the total timelapse duration if you don't adjust the interval, i.e. recording two frames instead of one will double the length of the timelapse.

Sorry, I need to correct a few things. Some of the stuff I wrote I got mixed up with functionality from DV Rack HD's timelapse feature -- the camera itself doesn't have all of the functionality of the former.
With the camera, the timelapse interval can't be selected as freely as in DV Rack, and contrary to what I wrote before you can't record more than one frame per interval, so you'll have less control over how long the timelapse winds up being.

also, you can't Interval Record in native (pn). You have to be in 30p or 60i (Barry book, pg. 162)
