Press Release: HMC150, "the new DVX"

Flipping might actually be a possibility. The two most recent products they've introduced, the HPX500 and the P2 Gear, both have it. So it's possible!
 
I was going to upload a frame grab, from one of the SD9 clips I shot at Circuit City the other day, to show the trailing/ghosting effect I noticed, but it seems I am far to limited as to how large a photo I can upload here.

Pretty awful image but I think with better lighting it would look better. Also, it is only running 1/6 inch CCDs.

The lighting in the store was ample, but that image was shot at maximum zoom (and focus is off too), with considerable camera motion. Presumably, the three 1/3" CCDs in the HMC150 would perform better than that (one would certainly hope).

I posted that, because it is a pretty pronounced example of the trailing/ghosting effect I noticed, that looks to me to like artifacts from temporal noise reduction. If that is what it is (temporal noise reduction), perhaps it can be turned off in the SD9, and I would certainly hope it could be in the HMC150.

What concerns me, about that trailing/ghosting effect, is that somewhere I read about that sort of effect with the Canon AVCHD camera that uses the exact same imaging head as the HV20, and that effect isn't seen in the HV20, so possibly it might somehow be compression related (and would not bode well of it is).

I'm going to try to find a frame grab that is a pronounced example of blocky artifacting from motion (stress on the codec). From what I've seen in the images I shot at Circuit City, I think the HD9 does fairly well in that regard, which would be a good omen for the HMC150.

As we would say here in W. PA, "I'll say." That's an awful image. My DVX100 takes WAY better footage than that and even with a lot less light. I wouldn't pay 10 cents for that picture. If I were a bride, my comment would be, "I'd see ya in court." :o)

You mean that ghosting/trailing like is visible in HDV when zooming, under average light and some movement? Hmmmm. Serious compression at work possibly?

That was shot with a Panasonic HDC-SD9 (AVCHD - not HDV). I was intentionally trying to stress the camera there (not shoot beautiful footage). Moderately fast panning induced that (faster than you would normally pan).

That trailing is not real noticeable at full speed, but it is a concern.

Actually, I do understand that and have been following this thread closely but the image that I see looks a lot like regular DV would do or HDV, that is the typical GOP which of course it is. Yes?
 
What I meant by "moderately fast panning" and "faster than you would normally pan" is that the panning there was faster than you would usually pan, especially while shooting 24p, but not really what I would call a "whip pan" either.

By "not real noticeable" I mean that at full speed, a layman would probably not consciously notice it (but it wouldn't look particularly good to the untrained eye either).
 
The trailing/ghosting effect looks like artifacts typical of temporal noise filtering, rather than artifacts caused by compression. What concerns me though, is that I've heard something like that described in the AVCHD version of the HV20 (and the HV20 doesn't do that). If it is somehow a result of the codec, that would be disturbing.
 
Robert M., do you have some good shots to post? That is, where light is the norm and not pushing the camera, just static stuff? Then, a blow up to see what happens?
 
I need to find someplace where I can upload full raster, uncompressed images. I wasn't really concerned about trying to shoot something that looks good, because I would really hope the HMC150 imaging system performs much better. What I was trying to do is get an idea of how well the codec might hold up under stress. The SD9 codec should be a reasonable facsimile of the minimum performance we might see from the HMC150 codec.

OK, maybe not.

Robert, thanks for giving us the grab.

How about posting a clip of the footage?

sincerely,
