Neutral Density and the Z1-U at DVinfo.net

I recently shot some ext. with Sony Z1-U and used N.D. However, some of the footage looked like it was "stepped on". Has anyone else come across this?

Having used the NDs a bunch of times, I haven't experienced any problems. Perhaps you could go a little more in depth in describing what you mean by "stepped on?"

I've never noticed a problem with the ND's either. Perhaps the use of the filter just caused the footage to be underexposed. Were you using the zebra pattern?

Hello Peter!

You wouldn't happen to be an Aussie by any chance?

When you see the "stepped on" effect, are you viewing on any device other than the camera's LCD?

If you are watching a computer screen and seeing the effect, what Media Player software are you using?

Have you shot with setting for the ND filter other than the one where you've noticed the effect? Did they show the same effect?

What were the light conditions and the shutter speed that were used when the effect occurred? This question really only applies if the above queries don't provide any real insight into your particular problem.

It's always nice to see a new user of a HD/HDV camcorder gettin' out and about... I would suggest that if you do post with problems you may be encountering, that you give as much information as is possible - even stuff you may not think is initially relevant, because it could be the clue to solving your particular hurdle to enjoying what HD/HDV can achieve.

unfortunately I have not seen the raw footage, I Fed Exed it immediatley. However, the editor said some of the footage looked "third generation". My first suspiscion was the downconversion was bad. Now I'm wondering if the N.D. filter produced a grainy effect. It looked fine to me on the screen. And no, I'm not the Treasurer of Australia.
