What type of tests/things should I look for to test the 24 Frame mode?

I'm gonna do an eyeball test, try out some things with the XL H1 floor models, and then head over to B&H to see the FX1, but I don't work with HDV enough to know what to look for.

Shoot a Putora chart if you can in both F and i modes - look for differences in resolution. Shoot something moving (like an overhead fan blade) with a fast shutter in the various modes.

Anyone know where I can pick up a resolution chart on short notice in New York City? Or at least point me to one on B&H Photo.

ZGC carries the Putora chart. B&H doesn't list it on their website (or I can't find it if they do). ZGC is in Mountain Lakes, NJ which is about 25 mi west of Manhattan. If you are there for another day they would probably Fedex one to you overnight if you were willing to make a rather substantial sacrifice for the cause - these things ain't cheap as I recall. There ought to be one or more of these things around the floor- it's a video expo after all. NY being NY I am sure they are to be found somewhere within the 5 boroughs but I have no idea where.
