chroma keying cameras

[Bob Zelin]

you write – “special background ”

It’s called a GREEN SCREEN. Perfect keys from a camera occur from perfect lighting. I dont’ care what miracle product comes out – if a scene is poorly lit, you will never ever ever ever get a perfect key.

That’s why lighting guys make more that anyone else on the set.

I understand your point… but there is a technology out there where there is a ring of sensors on a lens that allow for keying in “not perfect” environments, or in places where space is a factor..

if a technology can be more efficient, why not check it out…

Marc.

Thanks!

this is what I was talking about… still not sure how efficient it is.. but worth checking it out..

I know Datavideo well (although I did not know this particuar product). Datavideo has demonstrated low end chroma keying at the last 2 NAB shows with their piece of crap switcher. They have a motorcycle setup at the NAB booth, and people in the booth can hop on the motorcycle, and take a picture (with a fan blowing your hair), against a moving background (using a green screen). They use their DVD+R recorder (the MP-6000) to give visitors a copy of their “experience” on the motorcycle.

It’s super low end stuff, and compared to Ultimatte, etc. its as low end as you get. After going to this booth at NAB, I actually specify the MP-6000 as a DVD recorder all the time, as it’s the last of the professional stand alone DVD recorders (ever since Pioneer stopped making the LX-1). But most of Datavideo’s products are pretty terrible quality. The DVK-100 is their stand alone chroma keyer. It is what it is – it’s not professional gear. But great for a wedding or sweet 16 !

I have to agree here, if that’s the same as what I’ve seen at NAB, it basically chokes the matte until the talent drops to the ground. I’m sure some people wouldn’t know the difference, it depends on what you are looking for, no miracle though.

Will keep the old fashion way works like a charm 🙂

That’s a ripoff of the Reflecmedia chroma key system. I have the Reflecmedia Chromaflex system and it works quite well. No background lighting is necessary.

Thanks jason for the input..

even though they seem to be using the same type of technology, there seem to be a general acknowledgment that the 1st one is not good.. since you are using one (and probably looked at the datavideo one, what makes this one much better over the 1st one…

it looks quite impressive.. at least they have a video to show how it works..

what happens when you light the subject .. does it affect the screen lightness?

can you give me an approx price for this product?

what type of camera are u using with it?

thanks..

Thanks!

Hi Marc,

I think the others were commenting on the Datavideo brand in general, not specifically on their reflective chromakey system. For all I know it could be just as good as the Reflecmedia one. Lighting the subject won’t affect the chroma background unless you blast it with some serious wattage. They don’t recommend using it outdoors. As I recall, the Reflecmedia Chromaflex system with the 7’x7′ portable backdrop was about $2,300. I’ve used it with a DV camera and a DVCPro50 camera. It doesn’t make keying foolproof ––you still have to know how to use the system, but it does make it easier and faster because you don’t need to light the background.
