Question Reguarding Motion of HD100

Just read the DV article review on the HD100, and the only real complaint was the motion problems. As many people are debating over the HVX200 or the HD100, I personally like the HD100 better because it received better image quality in the HD Camera tests that DV magazine did. It also has been getting great reviews across the board.

Has anyone had any problems with the motion of the camera in 24P due to the MPEG-2?
 
What do you mean by motion "problems?" What I got out of the article was that the HD100 is the only camera with true progressive capture (no de-interlacing or pixel shift.) This, to me, seems like anything but a problem.

As for MPEG2 compression, the HD100 and 6-frame GOP handle motion extremely well - especially when compared to Sony's 15frame GOP.

I got the impression that when tapping the motion looks great, but when on tape it appears less smooth because of unused frames (It shoots twice as many as it records)?

Also, how does Lumiere HD handle 24P from this camera (As Final Cut isn't there yet)? I.E. what format does it convert the HDV 720 to? DVC PRO HD? Also, does it have pulldown?

As far as the motion goes I have nothing to complain about. I have only positive experiences when using this cam to capture sports and other fast pace motion shoots.

I re-read the article and the motion is only a very slight problem if panning is done wrong or something like that.

My biggest concern is the "Split Screen" affect, but appartently it can be tested before you buy the camera.

I am almost convinced to buy this instead of the HVX...especially if FCP 6 is unvailed at NAB.

Motion would only be a problem for people who are not familiar with shooting film. The panning speed's for 24fps have been established for decades. Remember the HD-100 must be treated like a film camera in 24p mode, therefore one must abide by panning speed parameters for 24fps in order to get smooth motion. This may be something new to anyone who's only shot interlaced video. One thing is for sure, if one learns how to use the HD-100 they will be rewarded with better shots than they would ever think to try on a 60i camera.

I can understand your concern about split screen effect, however, JVC has tackled the problem quite nicely to reveal a gem of a camera at a bargain price. The split screen has been well documented and there have been very long threads explaining as well as finding solutions (from the beginning). To get full native rez @720p the HD-100 is the only solution.

[SIZE=+0]Yes I agree but if you watch some motion pictures that are shot in film some times the pans are faster than you would expect and I see very little motion jitter compared to my hd100 even when panning slow I guess thats the difference between this camera and the top end motion picture cameras.[/SIZE]
 
Here we go again...

There's nothing magical about 24 frames per second with a 180 degree shutter (1/48th). This is simple math.

The camera behaves as it should.
Are you viewing the footage from the analog output of the camera, or are you actually capturing it to a 24P (23.976) timeline?
 
Interesting -- according to Mike Curtis of HDForIndies, the JVC doesn't actually put 2:3 pulldown on its analog outputs. Mike thought so and printed so, but he was corrected by David at Cineform, who says that the analog outputs are actually putting out one duplicate frame (i.e., four raw frames and then the fourth is duplicated for the fifth).

That would indeed make the analog outputs look more "stuttery" than a traditional film telecine. So maybe that's what you're seeing?

Regardless, the motion is captured "right". On the tape and in the editing suite (on a 24p timeline) it will deliver motion the same way film does.
 
Wow! I didn't know that, I am viewing it only from the anolog output. I am purchasing final cut pro 6 at the NAB so I was hoping it will edit in native 24p, but I did not know that what I was seeing in the analog out put is different then what I will see in post once it has been downloaded, thanks thats great news.
