GR-HD1 Edge enhancement

I've seen a lot of discussion on this board about the edge enhancement on the HD1. (Mostly negative.) So what exactly does it do? Why is it bad? What does it do to the images? Is the HD10U so much better because it doesn't have EE?

Thanks!

The edge enhancement makes the image look sharper on consumer televisions. In many cases the edge enhancement is fine and may even be desired. The problem is if it is not the look you want, and it is not practical to remove it in post. The HD10U has been modified to greatly reduce the EE, offering more freedom in post for the professional to create the look they want. EE can be easily added but not taken away.

Examples...

You can click on this thread to see first hand what it is and what it does to the image.

There's also some shots that were apparently setup identically with the HD1 and HD10 to show the difference in edge enhancement on the same shot (first set of photos).

Personally it doesn't cause me that much of a problem on 99% of my shooting (I have the HD1). It is very apparent in shots like the ones shown in the thread above (powerlines, radio towers, etc).

Basically it adds artificial dimesionality to images that really don't need to be enhanced. It's like the sharpness on the TV. If you can deal with it, it's not that big of a problem.

Yeah, I'm not a fan, either. Darren Kelly's HDV JumpStart DVD provides some great examples, too. That's where I saw what the HD1 looked like and was grateful I bought the HD10 last July.

Edge Enhance vs. Chroma Noise

I notice the EE in my footage now that I'm aware of it. I think I can live with it for the most part.

What REALLY needs to be corrected on these cameras in the Gawd-awful CHROMA NOISE. The picture would be so much more beautiful if this flaw was fixed. I did some test shots with some Valentine Roses. The footage was incredible, the chroma noise ruined it.

The chroma noise is mostly removable -- resulting clean images. Here is a thread on the subject http://www.dvinfo.net/conf/showthrea...threadid=20371. I have a free filter for Aspect HD users, and others a working on a solution for the Mac.

Great lighting seems to help in the chroma noise department.

I have found the level of the chroma noise to be same no matter the lighting. It is true that it can be less noticable in brighter objects as there is more signal to the constant noise level. Once I determined this, the noise was easier to remove.

JVC HD1/PD1 filters?

Has anyone tried using the HD1 with different filters to see if this can help reduce the EE? Also does anyone know of a matte box / filter adapter which will fit the HD1?
