As the months progress, Jupiter will get to a better position in the sky at better times of night.
Best capture time for Jupiter is 3 minute videos, for Saturn and Mars it's about 5 minutes (due to rotation speed of the planets). With my C9.25" SCT and 2.5x PM and ASI224MC, for Jupiter I set my shutter speed to about 6.66ms (so capture at 150fps) and adjust the gain to get the maximum histogram to be about 50% of full scale (around 300 normally). For Saturn I image at 100 fps and adjust the gain for 50% again. For Mars I image at 200 fps.
Have a look at this CN posting, it explains FireCapture and the settings you need very well. Looking at your parameters it appears you may not be using hi-speed mode, a reduced ROI or crop video mode. (Apologies if you are, it's difficult to tell). Posting the Firecapture log text file would help more.

These videos might help if you also if haven't already seen them. They cover equipment, Firecapture, Autostakkert and Registax amongst others.

Awesome thanks so much everyone for the advice. Just waiting for that one clear night over a night where i don't have work the following day.
