Continuous light to flash lights conversion?
I am new to still photography. I come from a film world where I know how many 1ks, 650w etc. are needed for a scene. But strobe lights are measured in watts per second not per hour...so I have absolutely no idea what I should be buying...are there any guides online that are good at explaining what wattage is necessary to light a scene (I've already looked on strobist and found nothing helpful) -- Any sort of conversion that can be done?
Thanks!
Well wattage isn't that important for stills. Much more important is the output of the flash. How long that output lasts also isn't such an issue. As such I would think start looking at guidenumbers instead of wattage.

Flash color temperature is from the Kelvin scale. I believe that's the same for film (video, not to be confused with photographic film). And you still use gels.
Advice:
Still photographers often think of photographic film when you say film. I had to read your question thrice before I figured out you meant film moving pictures rather than photographic film
