What causes the colour alignment to go out as per here:
And, is it fixable? The camera is an XH-A1. I've tried going back to the default colour setting, but that's made no difference. Appreciate any input.

Re: Camera colour alignment
hmmm, I don't see ( could be my lamps though) any colour out of alignment, just colours in different levels of shadow.

Do not follow, I may not lead. Do not lead . . . I may not follow.

Re: Camera colour alignment
I too see no colour issues - but the colour fringing could be lens artefacts maybe? The colour of them seems a bit wrong - so maybe something odd in the setup menu? Detail to high, that kind of thing?

Re: Camera colour alignment
I guess the pic is too small, though it's taken straight off of the camera. On a 40" TV, it looks very poor. Shooting some speeches a short time ago and I wanted the Groom in that third while the father-in-law was talking about him. Looked terrible. Almost that 3D thing (though no complaints thank God!) I went back to the very first wedding shot with that camera (about 6 years ago) and it looked much better - which is why I tried going back to the Canon default setting. I notice it now on TV programmes a lot to varying degrees, especially dark on a bright background. A recent wedding was for a cameraman from a well known TV production company, and he never mentioned anything, so maybe I'm being paranoid. surprise Or maybe...MY lamps are going!!! sad As an ex printer, colour registration is something I'm very attuned to.

Could it be the monitor display you are viewing your material on?

Re: Camera colour alignment
That is chromatic aberration on your lens.  The amount of aberration changes dependent on your zoom setting and aperture.  Sometimes you can't see it at all and at other times it is really obtrusive, generally when the lens is wide and the aperture is open, but not exclusively. 
 
Some newer cameras have software to lessen the effect.  Otherwise the more you pay for the lens the better it is.

Re: Camera colour alignment
Yes, that's been the opinion too on another forum. Strange though that it seems worse now than when the camera was new. What about SD Vs HD. Could that make a difference? I originally used the camera for it's 16:9 chip and shot in SD.

Re: Camera colour alignment
Well that would make a difference as obviously HD will resolve finer detail. 
 
Maybe there's been some small change in lens alignment over time, that's not unlikely as changes in temperature and humidity will slowly effect alignment in the best of lenses.

Re: Camera colour alignment
I need to to do some playing then in SD/HD to see what happens. If it is the case, I'm in a quandary - working in HDV gives so many more options as far as cropping etc.

Re: Camera colour alignment
One of the reasons I gave up with the Sony Z7 was not because of the HDV format, which many people were unhappy with but because I often found shots, especially wide shots with unacceptable amounts of chromatic aberration.  The main problem was that this was not obvious on location and only really raised its head when back at the edit suite and although others didn't really see it, I did. 
 
When I moved on to the Sony FS100 one of the main things I can see is that chromatic aberration is at such a low level even with the kit lens as to be irrelevant in general use.  In theory I could have upgraded my system by just buying a Ninja recorder (which I did anyway because I didn't want others to criticise the codec and also I saved money by not having to upgrade both my computer and editing programme) which would have solved the HDV codec issue but wouldn't have addressed the main issue for me, which is the chromatic aberration. 
 
The chromatic aberration that you are showing is nothing like as bad as that on my Z7, but once you are aware of a problem it does nag away at you.

Re: Camera colour alignment
Looks like chromatic aberration exacerbated by overly aggressive digital edge enhancement. Turn down the detail settings somewhat, and perhaps experiment with some test shots the apertures at which your lens performs best. High contrast edges such as those you have show are often problem areas, particularly in the corners.
