@chip it's best to test it on m43 lenses as they tend to give more aliasing.

If sharpness is the issue than contrast plays a role too. The B&W video Ian-T posted as an example has high contrast, and high contrast strongly improves the 'perceived' sharpness. If we're on the right track, old soft and low contrast lenses should decrease the effect. If someone who owns such lenses (Canon FD maybe) could run a test against a kit lens or other sharp contrasty lens we might see if it really makes a difference.

A diffusion filter might be a better option than post-processing blurring. It doesn't degrade sharpness.

@Mark_the_Harp I too have noticed what is being called judder (a staccato-like pattern on sharp edges and and regions of high contrast) in my footage with pan, tilt, and dolly movements. I believe sharpening contributes to the effect, for I have several pan and dolly shots with areas of soft focus that do not judder. It's only when the shot comes into focus does the judder occur. It also depends on the speed of the camera movement. Very slow movement does not seem to cause the effect, or at least it is less noticeable.

@Mark_the_Harp yep if the judder goes away, it's the sharpening/LCD issue. I never see my problem on unsharp areas. You can also try just blurring the image a little in post (same deal).

Hey guys, I just wanted to update what I was told about GH2 footage I sent out to a friend of mine that does post production work. He works on a bunch of high end films and I think what he says is golden. I actually believe him more than my own eyes. So what he told me is that it is in fact a sharpening issue. At first he agreed with my description about the problem and still thinks there is an " odd feel " to the GH2 24fps. After looking at it frame by frame he decided that the sharpening being done internally was causing the problem and can be perceived differently by different people. Just like some people are annoyed by fluorescent lighting while others are not. Someone mentioned earlier the rainbow effect with DLP projectors which might be the right idea.

I will say that in his first email he said the footage looked slower than 24fps but that was before he looked at it closely. I was told there may be a few things you can do to address this problem and that he will mess around with the footage when he gets some free time. Obviously, being able to reduce the sharpness would help but I'll wait to hear what he says and pass it along. A few other things that can have a negative affect were down rezzing and digital projection can highlight it as well. Their company actually fixed a film from China which had similar problems but for different reasons.

This is still a problem for me and others, I believe. I do think that there is hope in fixing it. Now, I really respect this guy but take it for what its worth. I don't think he spent a ton of time looking into this. It looks like this thread was heading in this direction on it's own anyway.

@bdegazio, yeah, basically the GH2 is just too sharp for it's own good : ). Seriously, it's easy to get addicted to sharpening, I was for a long time, but if you look at most cinema footage it's rarely as sharpened. That's why you don't often notice the LCD strobing there.

Also if you think about it, sharpening doesn't add any new detail (just increases contrast around edges), so there's no point having it burned into the footage when you can do it in post with more control (except for convenience if you don't want to do it in post). Also the extra contrast it creates uses up more bit-rate for no real benefit. And the high-bitrate patches already give you a more detailed image. So it would be great if (eventually) sharpening could be defeated altogether.

Guys, some patience.
I hope to move to film modes and related settings within August if all will be good.

@_gl Contrast / LCD issues - totally makes sense. Would be nice to disable sharpening completely I agree.

+1 on the last comment. Almost certainly the machine not the GH2. I see tearing on one of my PCs and not the other.

To my eye, this "strobing" effect is the same effect seen in any theater where a feature film is being exhibited. Features are shot and projected at 24 fps, as we all know. But, as I say, "to my eye".

@bdegazio I think 4) is a strong possibility. Maybe influenced by the unnatural way I'm in love with the GH2!
