Removing green background from videos (Chromakeying)

Hi,
I am currently trying to use JMF to remove green background from the videos I have recorded. I am trying to merge 2 videos ( 1 video in the background) and (this video w/green bacground removed in the foreground). Does merge.java from JMF do the job for the second part? Please help!!

Merging works only with one video sitting on top of another, but the top video positioned on the top left corner. Is there some way to have the top video positioned in the center? I am using the merge.java file from the JMF solutions. Any way to remove the green/blue background of a video using Java codes? Or is there a freeware tool to do so and then have the java program call it?

Removing background from video(2)

I want to remove the background from video easily and live,
using green screen like they do in most forecasts at tv news.
(where they display the forecast map...)
Is it possible?

FCP isn't a live switcher...it is a Non Linear Editing machine. You must first capture the footage, key it, then output.

How do I remove the background from a movie / sound problems

Apologies, not really sure what I’m doing…
How do I remove the background from a movie I made?
I imported a QT movie at 368/272 pixels, but for whatever
reason the HTML jumps up to 550/400.
The movie is still 368/272 but there is a background border
making it 550/400. Tried all sorts of settings in Publish but
can’t get rid of it. Can I keep the movie (and controller)
and not the background?
I can get round it by changing the background colour, but
surely there must be another way.
Also: My QT file was fine but the .flv has a stuttering
sound, any idea what could cause that?
Thanks, and Thanks!

Removing camera flash from video

Is there a way to remove camera flash from video clips within PE8? If not natively, is there a plugin that can do this?
Thanks,
Steve

Here are the best answers that I can offer:
1) why do you go from Premiere Pro to Premiere Elements?
Actually, about 90% of my work is in PrPro. The rest is in AfterEffects, PrE and other NLE programs. Basically, I use those, including PrE, when they do something better than PrPro. PrE will accept a broader range of formats/CODEC's, than will PrPro, so I use it to Import those odd Assets, and get them ready for PrPro. Same with CyberLink's PowerDirector, and Magix MovieEdit Pro.
2) How do you synch the audio and video (I'm guessing that you record off-camera). I synch it by eye and ear and it can be tedious. I don't have time code synchronized equipment
Most of my shooting is actually done with camera audio capture, though usually through either a shotgun, or wireless mics, attached to and recording to the camera's tape. When I do separate audio & video capture, I slate, so that I have the visual and audio sync. When I am faced with having to do manual sync, I will look for the visual and then the accompanying audio, and just nudge and listen. This ARTICLE will give you some of the mechanics of the process.
3) I don't know much about DD 5.1 SS and this is just from the point of curiosity at present, can it be a problem keeping long clips in sync?
I do not record to DD 5.1 SS, as that is a very expensive and technically challenging process. It takes six well-designed and well-placed mics, a multi-channel recorder and a mixing panel, run by a skilled tech. My DD 5.1 SS Audio is with regard to the music for my Projects. Some of it is recorded as 6 discrete channels and then mixed, while some is faux 5.1 and is "created" from 2-channel source material.
Much of the work from Hollywood is actually faux 5.1, in that the source material is seldom recorded in 5.1. Most is stereo and mono, and is blended from myriad sources. These can be SFX, dialog, ambient audio. Most of those are mono TO separate them out from any other audio sources. Narration is a good example. Few audio techs, would consider using a stereo mic for narration and would choose a very directional mono mic, so as to better reject other audio signals.
Now, I can take a mono SFX file and pan/fade (not in the terms of a "fade" Transition, but front to rear location) it across/around the sound stage. I can place that bumblebee anywhere that I want, when I want it with 5.1 SS Audio. I'd almost always work with mono sources, so that I have the pure signal with no clues as to the source location - I set those in mixing.
I must add that with regard to mixing of music, there are constraints on doing faux 5.1. If the material was not recorded on multiple tracks to begin with, the RIAA, and other organizations, greatly frowns on creating a 5.1 "master." That came after the failed quadrophonics experiments from the '70s/'80s. With Hollywood's music, the recording IS done multi-track in the studio/symphony hall, so it IS multi-track and just gets mixed down to 5.1 Audio. This will be about the only time that the audio is done multi-channel in recording, as few environments lend themselves to doing 5.1 during the initial recording. There are exceptions, like live concerts, but that is almost a genre unto itself.
Sync, in and of itself, is not difficult to maintain, but so much depends on the recording equipment. Many, using separate cameras and recorders, often find that there is sync drift, and need to establish the % of "cure." In the old cine days, we hooked our camera to the Nagra recorder, and chose which unit's crystal clock would establish sync. Then, we had a cable between the two. Nowadays with digital, it seems a bit more difficult. There are several recent threads in the PrPro forum about the sync drift between pro-level cameras and recorders. One user has found that altering his recorder's output by 104% fixes the OOS issues. Others need to test critically. The sync clocks in different equipment just does not match up perfectly, and there is usually no universal crystal clock that overrides the internal ones - like in the "good old days."
Hope that this helps. If I missed something, please let me know,

How do you remove the background from an image

how do you remove the background from an image thathas a white background?

First, change the background layer to a normal layer if needed, by dragging the padlock to the trash can.
Then use the quick selection tool or magic wand tool to select your background.
Now you can either delete the background, or click the icon at the bottom of the layers panel that looks like a circle inside a square. This icon will convert the selection to a mask.
The advantage of the mask is, it is non-destructible. In that you can change your mind at any time. Whereas deleting pixels is permanent once you close the file and there is no duplicate files. (A way around this is to make a duplicate layer and hide it. But that does make the file larger.)

Removing green screen from a video sequence in PS

How can I remove the green screen from a video sequence in Photoshop?

There's a bunch of tutorials for editing video with Photoshop on Adobe TV
http://tv.adobe.com/watch/photoshop-for-video/chroma-keying-backdrops/
I am not sure if the above link is going to help you though. Is this footage you shot yourself? If so what sort of camera, and how was the BG lit? I ask as chroma keying can be tricky to get right, and I understand that DSLR footage is far from ideal for chroma key for instance. I use a Canon XF300 which records with a 50mb/s 4:2:2 codec, which works well for chroma key.

How do I remove a green background from a pdf text document?

I posted this question yesterday and received one reply. I wanted to respond to the reply, but couldn't find a link or "button" to click on that would enable me to do that, so I'm doing it here. As I'm new to this site, please advise me where the link is, if there is one.
Please correct me if I'm wrong, but I thought that PDF was proprietary, with one "owner" and that PDF was PDF, so it didn't matter what program you had on your computer because PDF was universal. Second, when I googled Nuance pdf, I was directed to this site, specifically the "Create, Edit and Export PDF's" section. Third, I also have Adobe Acrobat with pdf and a bunch ofother Adobe products on my computer. So, that brings me back to my original question, how do I get rid of a green background on a pdf text document, so I don't use up all my ink when I print it. Thanks for your patience and help.

I still use Office 2008 but have not encountered that issue. However, as Office is not an Apple product, I strongly recommend asking in the Microsoft Office:Mac forums here:
Office for Mac
Everyone there is a Mac user AND an Office user, something you can't say about Apple's forums. You will get the fastest help there and I think you will find the contributors more than helpful.

How Do I: Remove White Background From a Non-Standard Sized PDF?

Hello. Been a little while since I was last here.
My issue is pretty simple. I am creating a PDF in Acrobat Pro X from MS-Word 2007. My document is landscaped half-page sized (US), so dimensions are: 8.5" wide, 5.5" high.
When I attempt to print to PDF, the dimensions come out correctly, but there is a white background which is the size of a landscaped 8.5" x 11" sheet. Against this background, the 8.5" x 5.5" area is situated (nearly) centered vertically, but "right-justified" horizontally (see image). I need to find out how to fix this.
Here's what I know:
In MS Word:
For "Page Setup" (under Page Layout tab):
- under Margins tab, orientation is landscape;
- under Paper tab, "Paper size" is "Custom size", with Width 8.5", Height 5.5" ;
- No changes under Layout tab.
For "Preferences" (under Acrobat tab)
- under Settings tab, "Conversion Settings" are a custom setting ("Advanced Settings"), with "Default Settings" of Width 8.5 inches and Height 5.5 inches.
When I Print > Adobe PDF:
For "Properties" in Print window:
- Under Layout tab, "Orientation" is "Landscape" ;
- Under Paper/Quality tab, "Paper Source" is custom with Width 8.5" and Height 5.5".
- Under Adobe PDF Settings tab, "Default Settings" is "High Quality Print (Custom)" with (Custom) being the settings I set under Acrobat > Preferences.
- Also under Adobe PDF Settings tab, "Adobe PDF Page Size" is custom with Width 8.5" and Height 5.5".
The result is pictured above.
The last thing I did before posting this was run Help > Repair Acrobat Installation in Adobe X. Any suggestions? You can't do worse than I have.

I'm trying to remove the background from pictures and PDFs.

Hello All, this is the 3rd or 20th time I've tried removing backgrounds. I install water equipment for a living and try to manage my website on my own. Each time my products change, my suppliers send me literature in PDF format. Sometimes I'm installing the equipment before I have the literature. I take pictures of every install I perform and would love to use my pictures without the dirty basement in the background.
I've spent hours trying to work with just one picture. All that fine detail, erasing, and zooming in and out, then click! I lose it, or can't save it, or it just doesn't work. I've watched tutorials, and watched it done right in front of me (on a PC) at my print shop. I thought I'd ask this community, because I've had 100% luck on here everytime.
So, can I use the same software to remove images from PDFs and backgrounds from pictures? Which do you recommend? I have Adobe Photoshop CS2 and Adobe ImageReady CS2. I also have Gimp that I downloaded for Mac. Since I've never been successful with any of them, I'm not sure which one is wasting my time.
Thank You,
Steve

Extracting images and removing backgrounds can be very complicated. There are many different techniques and methods for doing it: the trick is finding the right one for the image you're working on. Every image is different and what may work for one may not work for another. You can do all of the basic techniques in Photoshop CS2, though it's a little easier in newer versions. I'd recommend going through as many online tutorials on image extraction as you can tolerate. There are hundreds of them. (While I find him annoying to listen to, Russell Brown has made some excellent tutorials on the subject. Try this one to start.
While it is possible to edit an image embedded in a PDF, you really need Acrobat Pro to do it. Acrobat sends the image to Photoshop, where it can be edited, and then Photoshop sends it back to Acrobat after you're done. Or you can save it as a separate file. In the 20+ years I've used Adobe's stuff, I've never done that. It's usually much easier to do a screen capture of the image and then work on that copy. (There are some sizing and magnification issues involved with this, however.)
In Photoshop, pay particular attention to Quick Mask mode, learn how masking works, how to make a selection based on a color range, how to use the Pen Tool to make a path that can be used as a selection, and how to save and load selections. Getting a clean extraction takes a lot of practice and it's almost never quick or easy, but it's worth the effort to learn how to do it well.

How do I completely remove a background from an image & keep it as a .jpeg?

Hi , I already know how to remove backgrounds from images, and create a transparent background. However, I need to be able to use the resulting image in another program called Scratch. And as far as I know, it does not accept .tiff, .pgn, .psd or gifs.
How do I completely remove that background so that it doesn't show up white in other programs when I save it as a .jpeg?

Jpgs don't support transparency. It looks like Scratch may support pngs and other formats, but the transparency may not come through. From what I've read, you may have to use the transparency brush in Scratch to achive what you want.

Removing color gradient background from video - help needed

Hello everyone,
I shot my son playing the violin against a white backdrop today, and what was pure white didn't turn out to be very white, I have gray
areas, off white areas because of incorrect lighting.
I want the background to be more white and more even than what it is right now.
I thought of moving the video from track 1 up to track 2.
I added in a title, which consists of a big box of white ( using the retangular tool I just drew a large white retangle that covers the entire movie area )
Now to remove some of that white backdrop, I thought I would try some of the tools below, to remove the real backdrop, and let the white retangle
from track 1 come through. ( so that the pure white comes through from track 1. )
I've been going through the various options,
- Chroma Key
- Color Key
- Change Color
- Change To Color
After 30 some minutes of fldding around, I thought I would just stop, and ask for help. How would you proceed with this ?
What process would you use ?
I'm just puzzled as to which tool is best suited for a job like this, because right now my results are not to my liking, and it's just hard to get anything
that looks good at all.
Thanks for all help,
Dave.

Hi Harm,
Thanks for the great response, I don't have Ultra CS3, but will look into Keylight. I'm going to try the garbage mattes and chroma key route
for now and see what I can do.
You are indeed a weatlh of info.
Thanks again,
Dave.

Removing Blinking Text from video footage

Hi Helpers:
I recently recorded a service at my church where we have three mounted cameras. One of the cameras was malfunctioning and the word "Backup" is blinking in the top 1/3 of the frame for the entire service. As luck would have it the malfunctioning camera is the only one that can capture faces as people enter during the mass procession.
I knew this was happening while recording but couldn't remedy the situation at that time. I was able to frame most lf my shots so that the vital subject of the angle is below the blinking text in case I need to crop the video (which unfortunately will result in a blurry picture from that camera).
Is anyone aware of a way that I can use Premiere (CS4) to somehow remove the blinking text or perhaps other options aside from cropping?
It is a 50/50 blink cycle (12 frames on and 12 frames off) so there are a lot of frames that are good if there is some way to normalize the picture. There are so many cool tools and features in PS and Premiere that I want to think there is something that can help me.
Thanks in advance for any ideas or assistance you have !!
Ned

Ned,
Welcome to the forum.
Unfortunately, if the camera has "burned in" the "backup" message, the best solution would be to use the Fixed Effects>Motion>Scale, and probably Motion>Position to effectively crop out that message, by the Frame Size. Just Scale up to the minimum to get that message off-screen (Positioning if necessary), and living with a slight bit of quality degradation. Scale to the minimum to get that message off-screen.
Now, depending on the background, surrounding the message, you might be able to use AfterEffects, and its Clone Tool, to clone some of that background, over the message, but this will require a bit of work, especially if there is much camera movement.
Good luck,
Hunt

Need to remove timecode counter from video

I have some clips in FCPx that were converted from an old VHS tape with the white timecode counter accidentally displayed. I no longer have access to the original VHS tape so cannot reimport it without the timecode showing.
Does Final Cut Pro X have a feature or plugin that will remove or erase these timecode numbers from the screen by filling them in with surrounding textures so the numbers are no longer visible? It doesn't need to be perfect. I tried the Blur effect, but that just makes it blurry white. VirtualDub Delogo works but is Windows only. Thanks in advance

Try this out:
http://sight-creations.com/fxexchange/TCWmarkRemover.zip [free - license]
It does exactly what I described, with some extra optional enhancement tools.
To start with, don't stray too far from the default settings.
There's an onscreen control so you can drag the effect over the timecode (or watermark). Use the Size Height and Size Width sliders to cover the TC area. The rest can be used to "blend" pieces of the surrounding video into the space (but blur should still be used.)
Brief explanation of parameters:
Offset Distance: there are 2 copies of the video used to fill the masked area. This parmater controls sliding the copies, one from above and one from below into the space. They are blended together.
(I consider all the following "expert" settings)
Max Stretch Horizontal/Vertical: These controls scale the copies. It is not recommended that you go below 85%, just because when the mask is close to an edge of the canvas, you'll not have enough material to fill the space.
Mode: How the two copies are blended together. There are two. Lighten and Darken. They're both about the same except that in lighter video (surrounding the mask) Lighter will match better than Darker, and vice versa. It's not overwhelmingly important which you pick (there's more! see below)
Blur: applies a Gaussian Blur. Zero blur is available... recommended range: 200-400.
Feather: helps smooth the effect into the surrounding video... sometimes (it can create a kind of border effect OR a kind of "lens" effect.) You can do some interesting and/or weird stuff by abusing this parameter [along with Scale Height -- if you need > 400%, click and drag up on the number value.]
Roundness: lets you taper the corners
Saturation/Value: These two parameters let you try to match the surrounding video a little better and can be used to enhance or override the Mode you picked somewhat. Typically, use the "lightest" touch on Saturation. Value is the parameter you'll use the most. Left of 1.0 is darker. Right is lighter. 1.0 is no change/default.
Center: this is the location of the Onscreen Control. Typically, a watermark or timecode is NOT going to move over the course of a clip. That said, who says you have to use this just for those two things You might want to keyframe this to follow something...
All parameters, except the Mode, can be keyframed, so if you really want to work at it, you have the ability to minimize the visual effect that a portion of the screen is blurred out/obscured.

HOW 2 REMOVE WHITE BACKGROUND FROM JPG OR GRAPHIC?

I am trying to "knock out" the white background on some logo art that I am using on title pages. The logo art was supplied to me in both PSD and JPG format. I can certainly use photoshop to remove the white and save in layers, but when I import and place, the white comes back. Thanks in advance!

You need to save the PSD as a TIFF file or PNG with transparency enabled.
Simple way: separate your logo and background in Photoshop.
Make sure that the unprotected area is your logo. Press command C to copy.
Go to File > New > Film and Video Presets. Choose one that matches the pixel dimensions of your project. Make sure that Background color is set to Transparent. Click OK.
Paste your graphic (command V) into the transparent template. Save as above.
