Las Vegas (The show on NBC)

[RitualOfTheTrout]

Has anyone here ever watched this show? IF you have you would have seen all of the amazing things they can do with video. Like zoom in on objects a mile away from the camera and it looks clear and you can see whats going on.

Are these things really possible? Im not biig on all of that stuff. I just know when I zoom in or out on something on my PC it gets terribly distorted. Nothing nearly as usable as what they can do.

When you say 'zoom in' do you mean they zoom in on the frame, or do you mean a camera zoom (using a zoom lens)?

 

[racketboy]

I haven't seen the effect, but here's some guesses:

1) A really expensive zoom lens -- WAY better than what you have

2) A mounted camera traveling down towards the target and then sped up. Could also merge a few pieces of such shots.

I am 99.9 percent sure it's hardware wise, not software, but ya never know....

Well I guess I didint explain it very well.. Sometimes you see them do stuff like this on CSI also. Like they can take the tape from a bank ATM camera and zoom in on a certain part of it and they can see it perfectly. IE maybe read an inscription on the persons ring or necklace.

In las vegas they used a security tape and zoomed in on a particular location to see what number a guy typed in on his cell phone.

Maybe I explained it a bit better this time.. heh

A very high mm lens, that's for sure.

Actually, somewhat recently, somebody took a picture of Bush falling off of a Segway. Secret Service got really antsy, since they figured the picture was taken nearby (there's an outpost where photographers can take pictures, and they can't get closer). Turns out it was a 10,000mm lens (could be wrong, but it was a ridiculous mm) with digital zoom and interpolation. Pretty clear considering it was from close to a mile away.

If it's meant to be people using plain old security cameras to get these wonderfully enhanced pictures then it's probably bullshit.

They would be using very high quality camera gear (which the ATM camera wouldn't be) and possibly a fair bit of computer power as well.

Yeah thats more what I was getting at. I didnt think that there was some kind of magic filter you ran a clip of film through and get practically crystal clear zoom ins reguardless of the quality of the device used to intially capture the film.

Ah okay, so it's a drama type show? It's probably pure bullshit then, like on X-files when they look at a security tape or something and go 'enhance. enhance. enhance.' to the computer guy. 😉 .. It's possible to get super detail with a high quality zoom lens, especially on film, but with video it's really not possible.

'24' has done it a few times. In the first few episodes of this season they had some tech-related things that made you go "huh? 🙂

It's not possible - not to that degree. There is no magic "enhance" button, although you can do some interesting things with edge detection.

Let's say a guy is holding a credit card, and a security camera shoots it as he is handing it over to a guy in a shop (so the image is blurred as well). In CSI they'd freeze the frame, identify the credit card, cut it out, flip it around so that it is facing the right direction, hit the enhance button and presto - there is your CC number, name and signature.

It's just not possible to do that - to say that it's an order of magnitude more advanced than what we can do would be an understatement. If the information isn't there, you can't enhance it to the point that it suddenly is.

 

[it290]

Heh heh, tell me about it. I work in a large format print shop, and you'd be amazed how often people bring in a 50k jpeg or something and want it printed at 36x48 or larger. 😉

the real los vegas security cams are awsome watch a show about them they way better than the normal security cams and also probably better than airport cams.

 

[VertigoXX]

Monday's episode firmly revealed that they use software to do that. They brought in a security tape from somewhere else, taped a quarter mile away from a murder scene. Ed Deline says "Run that through that *something* filter I'm not suppossed to have," and presto, a perfect video of the crime. It's a fictional show, folks. Needless to say, they can throw in some sci-fi as far as the technology they have goes.

Even though it's fake, I think it's cool....I want one, haha.
