Frage von Styxer:
Hello!
First I want to tell you that you have a great forum that a truly helps!
A friend of me making movies as a hobby. He likes to use blue screen. I have worked with so far little at doing this, but by diverese items on the web, I have a certain overview concerning keying.
Since I own my home and gladly Programm on the theme of Blue / Green Screen interesting times I have thought a live-keying Leave program. (Those who are interested: I do programming in Delphi).
But since I have not much experience you need and what is not, I would now like to ask you what ye of such a program would want. It is told as only a preview to program, because I think the quality of commercial activity s.The codecs I can achieve in any case and therefore any export would be pointless.
More generally, I would naturally be interested if you can sowas really looking for, or should I leave it ...
A brief overview of what I've been thinking already:
Resolution: 640x480
Foreground: Picture, Video, Camera - is gekeyed
Background: Picture, Video, Camera
-evt. Garbage mask
Foreground freely movable and Zoom In or shrinkable

Hi
I have read your question now - and would be very interested!
I would be happy to help synonymous ready (logo, website etc.)
Mail me: silvan@ceo.la

S.sich That sounds very interesting. Only I can not imagine me just as real as you can imagine exactly. So what do you mean with one keying preview program? And how or what it should be used?
Maybe you can use the time to briefly explain in more detail.
Did you this way? While the camera is directed toward such a person before a blue box od green screen and with the PC (laptop?) Is connected, you can use s.Calculator the background you want already, and so perhaps potential problems in the illumination of the Blue Box / Green Screen early recognize and resolve.
Antwort von silvan:
this is what I watch TV synonymous conceived the idea - practically as in.
If he would spend that technically, if it were brilliant!
Antwort von aabich:
Foreground: Picture, Video, Camera - is gekeyed
Background: Picture, Video, Camera I am so slow I think synonymous understand this. Maybe. Is that what you meant, that synonymous with 2 cameras can be operated on? So that one is directed to the person in front of the Blue Box, the other alternative to a background. That one run "live mix" can be - was a preview of course, only describes how.
That would be, in fact, like watching TV. Now I do not know if and how it will proceed with two cameras, how then connects two cameras s.den PC. How did you have presented to you for, anyway? I suspect a Firewire connection between Cam and PC. Is that synonymous with 2 cameras?
The 640x480 Resolutionmacht probably less sense than for example a 720x576 resolution, since the latter is the standard recording format of DV.
Antwort von silvan:
yes, would be a solution!
render in real-time with a cam is certainly not very easy or very complex process, right?
however, synonymous with two cams, the basic idea would be pretty much the same (if I'm not mistaken)

Hello,
hope you still reading this thread.
So such a program would be extremely useful if one wants to integrate people with 3d objects or environments. Such a procedure was as far as I know, for the first time for the film of Artificial Intelligence Steven Spielberg used, so even in the professional sector is still relatively new.
For amateur filmmakers but that would be, as I imagine it still meaningful, because we could directly test how well the screen and the lighting.
Hizukriegen The program that runs in real time is not an easy thing. The only program I know of that can keyen in real time (but not directly of) the camera, and a pretty good job and the Liquid Edition (do not know if the premiere is now synonymous). It works in the YUV color space and use hardware support of the graphics card. Without using the GPU with OpenGL or DirectX, I can not imagine that the Keyen could run in real time.
Such a program would be extremely useful but in my opinion. Do you want to publish it under the GPL?

Antwort von micha3:
PS: just had an idea. Styx, you know AviSynth? This is a so-called FrameMaker Server. I have seen no Chroma plugin for this program. If you like to write, then you could in real time the edited material in almost any video program show and / or edit. Then that's missing is a capturing program, which in real time the stream of the camera Servert. But that will certainly go with VirtualDub. Since it Capturn and one Avisynth can be server, but do not know whether it is the same.
With such a plugin you would have the same advantage that it is not camera specific, would be suitable for all sorts of formats and you could still apply equally to other real Avisynth filter. In addition, it saves you a lot of work in programming, because you do the same with the main theme, Keyen employ can.
As far as I know it is possible for Avisynth in Delphi programming, it must halt s.end get out of a dll file. The web site is www.avisynth.org, it is under GPL.

Micah
