I have seen a few paks on air and they do not look good. They strobe and look very grainy.
I can understand the strobing, because chances are, he's using a 1/48th shutter.
That'll strobe like a mad dog when running against a flourescent light source, and totally freak on a CRT.
The only reason he would have graininess, on anything, especially in a newer video camera, is that he's using gain, or worse, an auto-gain setting within a camera.
I cannot advise enough to never, ever, ever, use an auto-gain, if you can help it.
A photographer should NEVER have grain in his video, outside of a night shoot. A 1/24th shutter is the highest standard framerate light level a camera can take.
SO- he's probably filtering so heavy, then gaining out of it. That's bad technique. He thinks the filter is depth, instead of the iris if he's doing that. That means he needs some edu-ma-cation. Or he's using a polarizing filter all the time outside, and that's just nuts.
That's screwing up your camera, like, intensely, if you're pulling 24p AND getting grain.
In my estimation, he's got a lot of tricks, if what you're telling me is right, he doesn't know why those shooting tricks should be applied. Don't model your shooting after this individual. Learn the mechanisms of light. A heavy filter removes color. Makes an image look dull. Pulls out light reflections. It's not good.
Polarizing filters are for specific shots, not all outdoor shooting...
Gain is also your enemy..
And so is 24p if misapplied.
Let's put it this way, if you think that only shutter should be used to get that 'sports look,' then it's time to talk.
