C100: Help understanding what I am doing wrong

I filmed my daughters volleyball game yesterday and the results suck and I do not know why. I usually film them with my canon gh20 and the results are great. I filmed at 30fps just like on my GH20 however it looks like the video does not keep up with the movement and I get ghosting (don't know what else to call it). Pay attention to the girl #14 and I think you will see what I mean. I have been happy with the Gh20 and I thought I would get much better results using the c100 but I am very surprised. I know it has to be operator error so any suggestions will be greatly appreciated.

Spartacus,

you are correct, I was set to 1/30. When I originally setup the camera I set it up to angle so it should have been at 1/60 What frame rate and shutter speed would you use.

Thanks
 
I just keep it at 180 degrees and leave it there 99% of the time. 240 or so in a pinch, but I turn it back ASAP.
 
Your White Balance not correct. And yes yr shutter looks not like 180 degrees. Just check it.
 
Ghosting: that's motion blur caused by using slow shutter speed. When filming movement where you want it to look sharp, you have to use higher shutter speeds. When you want to replicate the motion blur of films and movies, you should use a shutter speed of double the frame rate, i.e, 1/60s for 30p (this is called the 180 degree shutter rule). But that's just a guideline and I would choose over 1/120 for your kind of shoot.
 
Also keep in mind that the 30 is PsF so depending on how you are editing/importing the footage is will have weird interlaced artifacts. You need to interpret it as progressive. Even then I've had some issues, honestly, that's why I prefer using an external recorder for 30p stuff.

Although you may be better off with a GH20 for this kind of shoot. The C100's only real advantage would be low light, but you need a lot of depth of field to capture a scene like that. Maybe you have other uses besides sports games, but that's just a general observation.
 
Your frame rate is wrong. I used to see this all the time in the earlier days of HD and progressive scan cameras. Everyone was used to us shooting 30 interlaced frames(60 fields) in SD so they thought 30 frames progressive would look like "video". It does not(at least motion/cadence wise. We won't get into camera "look"/set-up/scene files). You need to be shooting 60 frames(59.94). Unless of course you want a "film look", then you should shoot 24. In GENERAL, when I shoot 60p("video", not for slo-mo), I have my shutter off(shutter is 1/60 automatically) and when I shoot 24p("film"), I shoot 180 degree.
 
I would have actually bumped the shutter up a bunch and give it a little pop. Sports always looks good with a high shutter look
