Blue/green screen garbage matte

can I generate a garbage matte to crop images out of my chroma blue/green screen in fcp 3?
powerbook g4, fcp 3, laCie 120g hd, laCie d2 dvd +- rw Mac OS X (10.3.2)

i've a huge green screen to light.
my subject takes up 10% of the screen.<
then you're not doing this properly. Shoot your person close and scale them to fit your shot, don't shoot them wide.
<div class="jive-quote">rather than light the entire screen i'd like to light around the subject (I will then see equipment/light stands, heads etc, in frame)< </div>
You're not making much sense here.
i'd like to generate a chroma key green matte over the objects i'd like to not see, (crop them out w/a green image) then key my backgd. image over the original & garbage matte image. < </div>
Oh. Now I see. You don't want to change the color of the matte in the chromakeyer. You want a green matte slug to place over the video so you can chromakey it out.
That's not how you do this stuff. Chromakeying is not rocket science but it's far more complicated than we c an explain in these little posties. You have a fundamental misunderstanding of the whole thing and, unfortunately, this isn't a film school. Unless someone has the time to walk you through chromakeying as a technique, this is where you come to find out how to use FCP. There are hundreds of informational chromakey articles all over the Internet on the topic. Start with google or your local library.

Blue Green Screen Filter

Hello
I applied the blue green screen filter to my clip. I obviously did not have the subjects feet lit up enough and Im having trouble getting rid of the green around that area. Is their another filter that would help with that?
Thank you.

As Telly said:
The Spill Suppression filter can be useful for excessive spill on the interior area of the matte. as the Enhance slider only works on spill around the edges.
Just make sure it lies below the Chroma Keyer and above any Color Corrector you may have.

Blue/Green Screen And Multiple Cameras?

Next week a number of us are demonstrating Blue/Green Screen filming and editing to members of our video club who are not familiar with the technique.
Originally the person who thought up the idea intended to have 3 groups of people filming a 2 minute script on a "station platform" a la "Brief Encounter".
So far, so good, but then the creator of the idea suggested we should shoot each scene with 2 or 3 cameras to make it look more professional.
I don't like complications when the aim is to demonstrate a technique, but somebody has suggested there will be a further drawback.
When we cut from one camera to another during editing, the angle of the "actors" will alter but the background will not!
This will create the equivalent of a jump-cut.
Has anyone done such a shoot, experienced this problem or found a (reasonably simple) solution?
My idea of a solution is to have one camera in a fixed position! But, then, I am lazy.

Hi Ian
You know me and my speculations (what You got without enough Know-How)
But I would try to first apply Green-screen effect to one Camera angle
at a time. Then I can get another background for Camera two etc.
Then save these as QT full quality .mov (or rather back to Camera and new tape
feel much safer this way) and re-import then and now prepare
for multi angle cutting. (By putting one Camera on each track. Minimizing size
to 25% and locate each to one separate corner)
Now playback and I will in Canvas see all Cameras in each corner and can by using
transparicy adjuts which one to be seen.
Then as a last action - upscale all to 100%
Done
But as You see this is me just speculating. I fell for FC-Pro and the MultiCam
function here. It's fantastic.

How to use blue/green screen?!

HI
I'm a new user to FCE so i maybe sound like a noob, but how do you use the methods of blue/green screen thing. !?
thx

"I understand from Wolsky's book that you really can't deal with HD green screen in Final Cut Express 3.5."
Really? I said that? There is one particular problem with HD material in FCE in that that AIC color space is 4:2:0. There is no color smoothing filter for this. I believe Graeme Nattress has one for this. There is a color smoothing filter for DV NTSC standard definition, which is 4:1:1. DV PAL has the same problem BTW, as it's also 4:2:0.
Aside from that the chromakeyer works decently with well shot material. For a really high quality key you should look to third party software.
There is no difference between 3.5 and 4 in this regard.

If you haven't already, why not give "blue/green screen" a try?

Legacy FCP and FCE could always do blue (or green) screen but FCP X makes it a real doddle to get a good key.
For my test I simply used a very cheap blue bedsheet fastened to a wall and without more ado filmed myself babbling for a couple of minutes.
The resulting clip was imported into FCP X and the Keying Filter was added.
There are numerous adjustments you can make, but none of these was necessary as the result was automatically OK.
Here are frame grabs showing the original bedsheet and the final result with a street scene superimposed.
You can click the images to enlarge and examine the edges which look pretty clean........... especially considering the the lack of time and expense incurred!
Obviously anybody can achieve the above results with no effort, so take a look at this short video from Vimeo showing how some of the special effects in "The Great Gatsby" were achieved.
For a visual feast I suggest downloading it and playing on an HD TV.

Now hasn't that pro clip inspired you to try blue/green screen ........... or maybe it's completely demoralised you?

How do I get blue/green screen option & split screen?

How do I get blue/green screen option & split screen? On iMovie, these options were presented to me, whenever I dragged a clip over another clip already in timeline. Where do I find these choices in Final Cut X ? Also, on iMovie, to resume project production, I would then hit the "done" button -- Where do I find a button to finalize changes? Also , where do I find the option of "precision editor" ? Thanks

Green screen is done with the Keyer effect.
There is no Done except for transformations in the viewer.
Double click an edit point to open the Precision Editor.

Special effects... Chroma key blue/green screen

Hello, im new to Final Cut, My friend is giving me his Final Cut Express HD 3.0 package and Im wondering if I'll be able to use a green screen/blue screen effect with this software, and if not, which software could you recomend.
Thanks in Advance.

Sorry Edirol if you took umbrage - my comments were intended as a light hearted quip.
As a peace offering, take a look at this old thread where I and others have made a number of suggestions to help new "chromakeyers" - not the least being how to do it on the cheap!

Blue/green screen

does FCP have the chroma key feature and blue screen capabilities? WHat is the best mac program for that...? What's the most affordable one?

the built in keyer in FCP is alright, I wouldnt say the best though. there are many third party plugins that will do a better job. if you are shooting in DV, I recommend DV Matte Pro from DV Garage
http://www.dvgarage.com/prod/prod.php?prod=dvmattefcp
Keylight is the best keyer I've used and it comes bundled with After Effects and Shake, although I'd wait for Adobe to release CS3 before buying After Effects, especially if you on an Intel Mac.

Blue/green screen - superimpose HELP

Okay, I'm new to this. I need to film two people, a devil and an angel, and superimpose them on another clip on someone's shoulders. Do I have to shoot in front of a special screen? Do I use After Effects and if so how do I do it? How do I extract them? Can any one help me with this? How involved is this? Thanks!

lighting is critical on
both subject and background.
Amen! If the lighting is uneven you'll have difficulty creating the key. You've asked a complicated question so start reading the manual and then you'll have a bunch more to ask.
For your sake don't jump into this without some basic knowledge or you're likely to have a mess on your hands.
I once had an employer put a subject in front of a piece of green posterboard and successfully key that video so yes it can be done. You'll have a little more trouble since your shot will probably be head to toe so that the angel can "stand" on someone's shoulder.
If you have the budget, rent a little time from your local television station and use their "weather wall." Make sure they have a head to toe wall, not all station do.
Good luck.

My ipod caught a colored blue/white/blue-green screen when i have updated it to 6.0

Hello when i have updated my ipod ti the version 6.0 it have bugged so i reboot my ipod and my ipod caught bug now it caught a coloured screen ive tried to restore it but it doesent work.

Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Using green screen

I know that I've seen several threads in this discussion before about using green / blue screen but I haven't come accross one that actually tells you how to work with it once you've shot. I made a green screen which looks pretty good if i do say so myself, but I don't know what to do once I've shot the footage and imported it into FCE. Can somebody please post the steps I need to take or a link to a website that would help? Thanks a lot,

Hi Alex.
I have just copied and pasted an answer I gave in October. It should get you started. As it says, try out the Blue/Green Screen filter first - it's easier than the Chromakey.
I have done a bit of Blue Screen work.
My Blue Screen is around 6'x 9' and cost around £3 (or $5).
It is a large medium-blue bedsheet I bought at the local market!
You can pay many hundreds of pounds for a proper one but mine seems to work as well as a friend's professional model.
All you do is pin it to a wall etc.and film the person or object, you want superimposed, in front of it.
You should try to avoid wrinkles although I have used mine when terribly creased and it has been OK.
Shadows are deadly, so I usually film outdoors on a cloudy day or in the shade.
Why outdoors? The subject needs to be brightly lit. If the camera has to boost the brightness your results will be unsatisfactory.
All you do then is put your background scene on Video Track 1 and the Blue Screen shot on Video Track 2.
Highlight the BS scene and from your Filters choose either Chromakey or Bluescreen.
You then fiddle around with the various sliders until you get the effect you want.
Many people use the Chromakey Filter but I have had more luck with the Blue Screen Filter and it seems easier to use.
Try it out. It's quite easy and as long as you do it my way it's not expensive!
Ian.
PS Make sure the person or object you are filming has not got a blue shirt etc.!

Best Chroma Key "Green Screen" ???

Okay...
Need to purchase the BEST (or really good) "keying" software out there (specifically for green screen). Is it "Primatte"? or?....or?....or?.... what?
And (ready for stupid question).... does Color Finesse do keying as well ? And does it do it as well as others if it does ?
Many thanks for your input. Have to purchase quickly.

Hello Andrew.
Just checking, but I assume you know that FCE contains Blue/Green Screen, Chromakey and Lumakey etc. filters?
I have used the Blue Screen filter in the past, coupled with a cheap blue 9'x 6' bedsheet and produced some very realistic results!

UK Sources of Blue/Green Plastic Tablecloths for Chromakey??

In a recent discussion on Blue/Green Screen work several contributors suggested using plastic tablecloths which sell for under a dollar in the USA.
I was all set to dash out and buy some when I discovered I did not know which shops would sell them!
The only shops I frequent are supermarkets and camera/computer stores.
I looked in Yellow Pages under "Party Supplies" but that seemed to consist mostly of magic suppliers and people willing to organize "adult" entertainment!
Not much help when all you wish to do is a bit of Chromakey.
So can anyone tell me where to look in the UK (preferably in the NE Cheshire region) for plain blue or green plastic tablecloths?
Ian.

Hi RobertFinalCut.
Thanks for your reply.
I have done Chromakey occasionally over the last couple of years using a large blue bedsheet that cost £3 in a local market.
The original letter in this post was as a result of considerable correspondence on the subject of Chromakey where a number of people claimed they got excellent results using the afore-mentioned cloths - particularly GREEN ones.
Over the last few weeks I have searched everything from "Pound Shops" up to giant supermarkets. Not only did they not sell them but when questioned the staff did not even know what I was talking about!
The nearest I got was in one very large Tesco Supermarket. They had a beautiful 5 foot by 7 foot plastic tablecloth for 99 pence. There was just one problem - it was bright pink! Hardly ideal when the subject is a "talking head"!
So my search continues.....
Ian.

Can you do Green Screen/Blue Screen/Chroma Key on Adobe Premiere Elements 12 for mac?

Can you do Green Screen/Blue Screen/Chroma Key on Adobe Premiere Elements 12 for mac? If not, what are the alternatives?

JimbobT
ChromaKey, GreenScreen Key, and BlueScreen Key are not included in Premiere Elements Mac.
Some suggest Videomerge as the alternative. I do not. But Videomerge is not THE alternative.
Instead, I prefer the Difference Matte as a substitute for the 3 absent keying effects. Please check out my blog post on that which includes
the how to.
http://atr935.blogspot.com/2013/05/pe11-difference-matte-as-substitute-for.html
The suggestion has met with good results according to the feedback that I have gotten to this.
I am strictly a Premiere Elements Windows user who does not prefer Videomerge even in Windows.
Please review, consider, and let us know the outcome.
Thanks.

How to retain an object (lader) painted blue in a Green screen set....

Hello there!
I would appreciate a piece of advise about a matter I am working on.
I have attached two photos and I will explain what I want to do.
I would like to key out the green backdrop in order to keep just the actors but I also want to replace the blue lader (the blue color) with a fractal noise patern so it looks like it is a burning lader.
OK I can make the fractal noise patern and give it the appropriate randomness. I have also find a way to replace the lader with the fractal noise solid (using alpha matts) but I don't think I am getting a very good result.
Could you suggest a way of keeping only the blue color instead of keying it out?
Thank you!
Yiannis.

Two keying passes, two layers, a fractal noise layer, dummy layer (see pic) and an adjustment layer for color correction nested above your keyed footage. Depending on the movement of the ladder and the camera you may have to do some motion tracking.
Pay very close attention to how I set up the fractal noise layer. This took about 5 minutes. Here's a CS6 project file for you to take a look at. Just replace the missing photo with one you posted.
Use the other picture for the project and redraw the garbage matte and the same project file will give you this:
