They really cannot be serious - tilt your tripod to eliminate the effects of Skew. Instead of trying to find ways (including software fixes) to mask what are inherent problems with current MOS technology they should be developing global shutter MOS and then launching new cameras. I have bought nothing but Panasonic for many years (including two-third inch CCD cameras) but this is laughable - we have to shoot in certain ways to 'manage' these effects? They should not be there in the first place. Staying with HMC.

PS Having shot F1 cars climbing the hill at Goodwood with MOS, I am in no doubt that the effect is there - even with what I would call average speed pans (the grandstand uprights and lamp posts were all leaning - unacceptable).
 
The video is basically saying rolling shutter is here to stay so here is how to deal with it. Sounds like there is no plan to make CMOSes capture globally.
This is why I own the JVC 700 series camera.
 
I agree that rolling shutter is probably here to stay at this end of the market, but I think instead of launching the AC series now and introducing work-arounds, they could have kept the HMC until MOS had a global shutter - then I would see the sense of changing over (and I would be happy to pay more for it). The technology is already there, it just needs development. The AC series with the HMC chip block would have been OK in the short term until the MOS problems were completely eliminated.

BTW, The JVC 700 series is indeed excellent!!!!
 
Well, the market is demanding full-res chips. That isn't going to happen in a 1/3" CCD, otherwise it would have already happened. And since the skew isn't an issue for most folks, that's where things are going.

Besides, this video is for the HPX300. The AC130/160/HPX250 is using the chips from the HPX370, which I was under the impression were significantly improved as far as skew goes.

I agree. That video is not about these new Panasonic camcorders.

This skew test done on the AC160 does not look bad at all to me. I simply don't see any problem worth noting.


 
The Original video was aimed at new hpx300 users as the 300 had a lot of skew at 1080 and some at 720, the 370 and 250 etc have vastly better skew so original video cannot really be compared at it was a differant product with differant chips.
 
O.K. It's back to the drawing board. You have convinced me to look at this again and maybe reconsider the validity of MOS. It was just that looking at the Panasonic advice video alarmed me (a lot).

Yes - I must say I am still happy with the HMC151. I think the reports of a 'soft image' may be more to do with focus not being absolutely accurate rather than a failing of the CCDs.

Yeah, I was editing a wedding I shot on my HMC150 today and was thinking something similar. I've seen sharper... but it's still plenty sharp.

I own one, and I agree that it's still pretty sharp. It's when I started editing a lot of footage from the HPX300, TM700, and GH2 that I really noticed the difference. For wide shots, it's even more prevalent.

I love the colors on the HMC150 though, and it still resolves more than 720p.
