Hi. I have worked days straight figuring out how to do a hologram effect using video. I saw the tutorial that guy had but that doesn't help me with video. If anybody has any ideas, i have PSP6, Photoshop 5, Premiere 5, 3dmax, and i can get any program. I and yes id o have a bluescreen, this effect would probobally be impossible without it. |

Okay, this is actually really simple. Film the subject against a black screen. (Film with a different tape than the one you're currently using.) Then play the tape on TV and set the camera (with the real tape) to film the video screen. This'll add the video strobing and noise to make it look more like a video projection. Then take the video into Premiere, and superimpose the hologram character into the background scene using the "screen" command. (I've tried, but chromakey and lumakey just don't work. Screen actually makes the subject slightly tranparent.) Then dub in sound, and there you go! |

Whoops! I forgot. In Premiere, before you superimpose, add a filter to give the holo-character a bluish tint. That helps.  |

You could do it in studio max just apply the avi to a patch grid, add some animated noise, smoke, or which ever filter you want. the only problem is you'll probably have to layer the video over and over to get the right effect |

I've produced the Star Wars Episode 1 Hologram effect with a great amount of success. Heres a still image without the final composit:
Film your talent infront of a Black screen. Velvet is best becasue it's the blackest material out there. Once you have this, import in into Premere and make it a filmstrip. Take it into Photoshop and reduce it to a greyscale. Make another layer that is your prefered tinge of blue. Use the Overlay transperencie on the blue so it is transperent to the greyscale filmstrip underneath. Now your talent will be Blue or whatever color you want. To give it that holographic look, your going to add scanlines. Make another layer and alternate with pure black and pure white horizontal lines every pixel down. So every pixel down will be a horizontal black line, then white, then black, etc, etc.  Give your scan lines a Soft Light transperancy and your set. Flatten the image and save it as a filmstrip again. Now you will have a blue image with scanlines. Much like the one at the top of this message. Take a filmstrip of your background footage, and layer the two together, (Experiment on what transperency to use). Then flatten that and send it back out to Premiere. The result is quite suprising. Message me if you want to see a video of this. Additionaly, if you want to, give yourself signal interferance by making thicker scanlines that scroll down the image. (a filmstrip of an AVI) You can also use different plugins to tear and mess up the image once in a while to give it that holographic look. Heres is a still shot of my animated scan line interferance scrolling down my image.
 Have fun. =) [This message has been edited by Andy (edited 02-05-2000).] |

Hi. I don't get the scanlines part either. And could you send your test film to mdecaro@home.com. |

also i dont get how to add the first .flm strip to the second... i tried opening the other .flm and just dragging it on, but that didnt work. I assume i need to make a new layer and some how put the .flm ontop the other one, but i dont know how.
THanks again. |

k even though i cant get the scan lines to work ive done some cool things with this.
Once its done in photoshop bring it back into premiere. splice it so maybe 2 seconds is by it self.Filter that 2 second splice with a lot of the blur filter. With the other splice, the majority, use the filer that duplicated it self. Make it so u can see the face well, so maybe theres 8 boxes. Then film a blue screen hanging on a door or somthing, with nothing else, make that transparrent, then have it so it looks li ke the face is on the door 8 times, like theres 8 monitors. It looks pretty cool. Ill upload a stil of what i mean in a bit. |

Hey Andy, you've got the same name as me! Ha ha! But anyway, I get the REGULAR scan line part, but what about the interferance? (spelling?) I'm not exactly sure how you add the scrolling lines, but if you want to go the simpler way, just film the holo-character off a TV screen. Then you already have the video noise and scan lines. Your idea does look better though. |

Scanlines in photoshop are easy. Open a new file with a transparent background, and make it 10 pixels wide and 2 pixels tall.Next, select your square marquee tool and go to the options box. Instead of a normal setting, put it on a fixed setting. Enter 10 pixels wide and 1 pixel tall in the options box. Then use the navigator to zoom in on your file as far as possible and click in it with your square marquee tool. Half of the box should be selected - fill it in with black. Now hit CTRL-A (PC) to select all (or change your square marquee tool back to normal and select the entire image). Then go to Edit->Define Pattern. Now you can go back to your hologram image, put a new layer in for the scan lines, and select FILL. An options box will come up, make sure it is set to FILL FROM PATTERN. And there you have it. |

*takes a deep breath*#1: NJRFilms, Puke666:
For the scanlines.. i took the jpg image in my last post into premiere and made a filmstrip the same length as my other filmstrip, but i like Sledgeweb's idea ALOT better. #2: When you have your second filmstrip, it's jsut like Lightsabers. Select all on the second filmstrip. Then copy. Then select your first filmstrip and hit paste. =) Voila! You have the layers together in one .flm file. #3: Mr.Hutt: Woo Hoo! Andys rule!
As for Animated Scanlines. I just made some in premiere. I created thicker white lines in Photoshop on a pure blue background. I took it into Premiere and used the motion option to move the image from the top of the screen down until it sinks down below the bottom of the screen. I used Transperency: Bluescreen with it and the other image was my original scanlies. So the result were these intermitant lines of varying thickness scroling down through the static scanlines. It looks good when made a filmstrip and layerd back into the greyscale image. If no one understands still.. i'll set up a Tutorial for it. #4: I'm experimenting with distorition as i write this, i'll get back to oyu all once i figure it out. |

why do you need scanlines... I have never seen a hologram in the real world that had one.you can use pepper's ghost and some creative lighting and create a hologram effect in camera if you experiment with it. if you want scanlines you could try using a TV monitor and reflecting a portion of the screen... and mask out the areas you don't want |

You don't NEED Scanlines. But if your going for a neat visual style, then they do help creating a look of a Sci-Fi Hologram. Remeber, Holograms in science fiction movies are more like 3 dimentional tv's then the trational laser created holograms of our day. But it isn't a must. I always thought it looked neat. =) ------------------

Ok here is exsactly how to do it! In the right order and everything
Film your talent infront of a Black screen. Velvet is best becasue it's the blackest material out there.
Once you have this, import in into Premere and make it a filmstrip. Take it into Photoshop and reduce it to a greyscale. Make another layer that is your prefered tinge of blue. Use the Overlay transperencie on the blue so it is transperent to the greyscale filmstrip underneath. Now your talent will be Blue or whatever color you want. To give it that holographic look, your going to add scanlines.Open a new file with a transparent background, and make it 10 pixels wide and 2 pixels tall.Next, select your square marquee tool and go to the options box. Instead of a normal setting, put it on a fixed setting. Enter 10 pixels wide and 1 pixel tall in the options box. Then use the navigator to zoom in on your file as far as possible and click in it with your square marquee tool. Half of the box should be selected - fill it in with black. Now hit CTRL-A (PC) to select all (or change your square marquee tool back to normal and select the entire image). Then go to Edit->Define Pattern. Now you can go back to your hologram image, put a new layer in for the scan lines, and select FILL. An options box will come up, make sure it is set to FILL FROM PATTERN. And there you have it.
Flatten the image and save it as a filmstrip again. Now you will have a blue image with scanlines. Take the filmstrip of original shot, and layer the two together, (Experiment on what transperency to use). Then flatten that and send it back out to Premiere. Next, to make it look cooler add signal interferance by making thicker scanlines that scroll down the image.To do this make an image in photoshop or paint, and have the top half be black and bottom half be white. The size doesnt really matter, make it a little smaller than your screen, and that should be good. Save it and open that in Premiere. Go to motion and have the start be at the bottom and end be at the top. Have it be perfictly straight from start to end. Save the motion and press OK. Make the orignal image you worked with the 50% black, 50% white, be the length of your scan lined film strip. (You can import that to double check, but dont keep the film strip there). No export that as an .avi . You can finnaly load up that finnished film strip file and then signal interferance avi. I like to speed up the singal interfernce avi to about 200%, then copy them and have enough to be as long as the film. strip. | |
