Just got the new C100 Mk II! (thanks Eric C. Petrie) Coming from the XF300, I've got some learning to do. I have done some searching, but haven't found the answers I am looking for... a few questions:
• Is there a good resource to download picture profiles? What's your favorite?
• Frame rates: Most of my finished product ends up on the web. Should I shoot 60p, 30p or 24p most of the time? 60p for sports or slo-mo? 30p for general stuff? 24p for interviews? Advice appreciated. I always shot 30p with the XF300. I will be shooting a basketball game tonight so I'm going to try out the 60p AVCHD 28Mbps
• Generally going with 180 angle shutter, 640 ISO (does it matter whether I use ISO vs gain?)
I have always been a video guy with fixed lens canon camcorders so using photo lenses is new. I'm accustomed to "iris" and "gain" vs iso, aperture, etc. And where's my zoom rocker?!?! LOL ;) Thanks much.

Picture profiles from an old C100 will gives you a different result, you must use only new version from the C100 mark II. Black level, colors, everything is a little different on the C100 mark II due new procesor Digic DV 4.

Edit:
The best start point for CP is to use WF monitor (turn on WF) and C100 connect with TV in camera mode and make a basic adjustment of black level and color gain (saturation) for basic gamma curves (cine1, wdr, log).

Canon - log testing on C100 and C100 mark II.

Here is my test of the C100 mark II:

Canon test C100 mark II vs. C100 (mark I), canon-log, wdr and cine1 gamma (2015/3) on Vimeo

No NoiseReduction, all camera settings are the same (with Black Balance) including black level (only color gain on my old C100 was little different for wdr a cine1 gamma CP, but not too much), color temperature was set with Kelvin (3600K).

Color correction vs. rough footages, canon-log, wdr and cine1 gamma (used lenses are at video).

It is not brilliant, but good enough for basic comparison, I hope this help (dark blue color has a little worse signal/noise ratio than other two colors, but the external recorder can easy solve this problem. It is better to download an original file).
