JVCHD100 questions...

Hi, I am new to the technical side of digital film making and I have some (naive?) questions about the HD100:

First:

I watched this video provided by Salatar at vfxtalk.com: http://www.salatar.com/users/stephe...ble/filmout.wmv

And I have a concern about how the image flickers/ghosts. Is this something that is a user issue or a camera issue. I mean i know 24 frames a second is slower than 30, but when I watch Hollywood movies I usually do not see flickering, I also watched the following footage that was shot on the XL which does not flicker like the above image.

Second:

Does the HD100 shoot Hidefinition in 24P or is Hidef only something you get with 30P?

Third, a question about HD200 vs HD100:

Will the HD200 shoot in 1080 or in 720 like the HD100? In fact, what about the HD200 is worth spending the extra money over the 100?

I'm aware that some of this information is probably on the net and I've been searching for answers, but after a couple weeks of looking, I figure I should just come out and ask those who know better, directly. Thanks for any feedback.

This is a characteristic of capturing frames at 24 frame per second. Here's more:

One characteristic of 24P that drives some people crazy is strobing. Because of the low frame rate, pans appear to "judder" or "strobe." This is one of the technical factors that led to the aesthetics of the slow pan and dolly move in mainstream cinema. JVC addresses this problem with their patented Motion Smoothing process that produces 24 frame per second images with less judder. The footage I've shot with the motion smoothing turned on does in fact exhibit less judder. JVC accomplishes this by taking the 48fps stream from the CCD and gently blending pairs of frames. You'll want to turn off this feature if you're looking for authentic 24fps image strobing typical of footage shot on motion picture film.​

The above paragraph is from a "First Impressions" article I wrote about the JVC HD100U back in November, used with permission :)
 
Ok in your opinion would you say the filmout footage in my above mentioned link is done with or without the Motion Smoothing process, applied? (If so, I'd hate to see the footage unsmoothed!) And is this something that is inherent of actual film making (say using 16mm) at 24fps that I simply haven't picked up on, or is it strictly a DV issue?

If this occurs in some real film movies, my belief is that it is simply something a good cinematographer can eliminate (at least with actual film.) But that's just my assumption. Do you think this could be true?

I only have limited experience with a DVX100 and an XL1 and have not used any DV cameras indepth.

hvx200 has more frame rates and modes and shoots in a more robust codec (dvcprohd) and records everything to very expensive p2 cards--mini dv excepted.

the hd100 shoots in a less robust codec (hdv) but can record to cheap mini dv tapes thus providing longer record times and built in archival solution. jvc also has a more profressional form fact (shoulder mount/interchangable lenses) and more manual controls.

image wise they are very similar, the jvc sems to have slightly better resolution, the panny slightly better color.
 
Thanks, I'm more interested in knowing the differences between the JVC HD 200 and JVC HD 100.

I've looked at the HVX200 but I'm not really that interested in it.

HD100 can shoot both high-def and standard-def in 24P. It can only shoot 30p in the high-def mode.

The forthcoming JVC HD200 will be 720p-only.
In fact, what about the HD200 is worth spending the extra money over the 100?

A few things; the ability to flip the image in-camera for using a 35mm lens adapter and the ability to record 720/60p are probably the main upgrades.
 
Senility is a terrible thing, I thought you were talking about the hd100 and the hvx200.

So, what Barry said.
