Standard Def HVX200 problems

As I said, if the detail in the pre-set scene file was set for an HD picture then you should expect to have to change it in order to gain a viable picture in SD. HD can handle much more detail than the SD signal can and thus while you call it eviserate, I would call it adjusting it to a useable level for standard definition.

However, I am not in a position to look at this until I am really back in Secaucus and have a lab to work in. Anything that may be posted from the NAB floor can only be subjective. And I am not even there yet.

Best,

Thanks for the input everyone. We own two HVX’s and I did a compare just to make sure that one was having a specific problem. Unfortunatley the jaggies were present and exactly that same on both cameras and now with your input I am convinced that this is an issue for everyone. I have adjusted the detail and that helps some, but I think it only slightly masks the problem.

The only way that I have been able to get ride of the problem is by dubbing the footage – compositely to a DVCpro50 deck. The jaggies are gone but so is much of the image quality.

At this point the only other way around it seems to be shoot HD and downcovert which presents huge storage problems at a station(PBS) shooting multiple long format programs at the same time. We are just not ready for that yet.

I am at NAB now and will do my best to discuss this with any and everyone who will listen that has experience with these cameras.

I will post any answers that I get.

Rich, i’m glad you are on top of this and asking questions. I hope to make it to NAB on tuesday.
If you expect to be there give me a ring 415-730-6938 or my email is
nsll@pacbell.net and tell me how to reach you. it would be good to touch bases.
My guess is the engineers know about it and it is a just a result of how they created the interlace signal.

Hi Rich,

We have an area on the NAB floor where there are cards and potential to talk, the HVX FAQ pod. The cameras are loaded with P2 cards and we can check them out on the monitor next to it. You should be able to find me, I am in a red scooter cart(broken knee cap.)

Monday may be a bit of a mob scene, but if we are patient we should be able to get to a camera and experiment.

See you there.
