Green Screen Backgrounds and Converter software

Hello all! I am a HS teacher and my students and I are making movies with IMovie to liven things up a bit. I want to put my students in the background of things like a basketball game and then move to the news room. I found free stock film for backgrounds, but generally I would have to covert it to fit a mov file. What is a good converter. Does anyone have any suggestions for some good backgrounds that I can use? I prefer free, but if there is a program under $100 that is awesome, please tell. Also can you rip off of Youtube and then sample bits from other peoples movies? I am sorry for so many questions. We just have no idea. THANK YOU!

Mpeg Streamclip (free), plus the perian.org plug-in-package is usually the 'swiss army knife' when it comes to conversion. for converting mpeg2 you need additionally the mp2-playback-component, apple.com/quicktime, 30$.

Do your own. nobody knows, what bg suits your needs most - nature photos? artistic abstract? apps like Apple's Keynote offer a wide variety of backgrounds. with paint apps a Pixelmator, 79$, you can instantly create colorful backgrounds.

Live type files look grainy and do not fill the background when used for green screen backgrounds.

live type files look grainy and do not fill the background when used for green screen backgrounds. Ideas?

What I want to do is somehow make my entire iMovie project smaller by compressing it somehow but without losing any footage or audio or quality. At the moment the project is a 56GB iMovie project lasting approx 1hr. I have a mixture of miniDV footage, titles created in Live Type (they are better quality than anything available in iMovie) and audio.
The miniDV footage is automatically compressed when it transfers from my camcorder to my Mac, no worries there.
The LiveType titles contain a motion background (imported into LT) and then text which appears and disappears at set points. The titles vary in length but are about 5 seconds each.
The file size for the LT titles is approx 180MB per clip, the movie requires about 20 or so of these clips, making a very large file size overall.
Is there a way that I can save something in LT so that the file size is smaller yet still keep the quality and use the clip in my iMovie ?

I've tried 50x to do a green screen. I need step by step help. I have my green screen clip and my scenic background but I can't do it.

Only raw video can be used with green screen background? What?

Latest of all software.
I have played with green screen a lot trying to make it work. The instructions say, and the only way to make it work, is to drag the background only to main time line in project pane, then drag a raw video clip from the events viewer on top of it, and choose green screen. This makes the video clip an add on to the main time line which is the back drop (like a title is an add on to a video clip).
As I have railed in other posts, this doesn't make much sense. But the real problem is you can only drag RAW video onto the back ground from events, and can not edit it any way afterwards (since it is treated as an add on, not the main time line). You can edit the back ground, since it is in the main time line.
The bottom line is: you cannot drag a RAW video onto the project pane, edit it and get it the way you want, and then add a back ground via the green screen. This make no sense.
Am I doing something wrong?
Any ideas?

Well, here is a convoluted method that seems to work...
1) drag the raw video to the project pane, edit to your heart's content.
2) save it as a .mov file (i.e. you are all done with it no more changes...ever).
3) import that .mov file File, Import as a new event.
4) drag the background(s) on to project pane, make it long enough for video
5) drag RAV .mov file (which is really a finished edited file) on to background, choose green screen).
You now have an edited .mov with a green screen background.
Could green screen be implemented more poorly? It would be hard to see how.
I still feel like I am missing something. Any ideas?

What is the correct method of removing a green screen background to insert a new digital background?

I am using Photoshop Elements 10 and can't seem to remove the green screen correctly. When I select the "magic wand" and click on the green screen background it selects it as it should. But when I hit the delete button on my keyboard it deletes the green background but a white background remains. So when I go to select my image to drag it to my digital background the white background goes with it.
In the tutorial video I watched it shows a grey and white checkered background after deleting the green screen which allows the user to select and move only the image to the new digital background. I am following the steps exactly but still can't seem to get it to work. Any ideas?

I don't know about 10 but in In PSE 8 there is a "Magic Extractor" ( ALT+SHIFT+CTRL+V) (on the mainu it's under Image ) which makes waaay too easy to seperate a selection from the background
http://help.adobe.com/en_US/PhotoshopElements/8.0/Win/Using/WS083AC514-D907-483b-84A1-4EA3 989C4C65_WIN.html
As already mentioned, the trick with the "background layer" is to right click on it in Layers and use "Layer from background"This will turn it into a "regular layer".
Then add a another new layer and on this new layer paste your cut-out you created earlier using the magic extractor.

Do you know of any safe/free green screen background videos/pictures?

I'm looking to do funny stuff like fake surfing, running with the bulls, celebrity pictures/interviews...Do you know of any websites that provide free green screen backgrounds?

I understand your colleagues quite well. With all benefits of programming in G, documentation, verification, version management is still an open issue. I have not seen NI source code control in operation (and currently we lack the $), so this might help. But I am getting uneasy more and more as our current project grows and grows.
Talking about source code management, that does certainly not mean a "diff" of two C-sources on an editor. I was working for a company that sold SNiFF and had the chance to use it free of charge. Well, that was a great tool. I still miss something similar for G.
Labview VI's have a tendency two develop easily into a mesh of crisscross lines that are difficult to follow and understand unless you redraw again and again those wires
meticuloulsy, regroup here, combine there, sub-vi somewhere else. Everyone is a new version without a real change of the logic. And you better have a dual monitor system and of course a 21" screen, but that you know!
After all, vi-editor is still going strong in certain groups although IMHO it should be dead and buried since 20 years ago. To say that that a vi diagram is the future and take it or die is harsh. A good sourcecode tool would help it's acceptance a lot.

Live Green Screen Broadcast and Record - Which Software and hardware? DESPERATE

I want to setup a stand (for example in a shopping centre) where I can give the opportunity for people to star in their own movie and they will get a DVD straight after them being filmed.
Below is an example of what I mean:
There is a green screen with a toy car, big enough for a child to sit infront of the screen. A parent pays me for their child to star in their own movie. The child sits in the car for 3 minutes playing with the steering wheel and pretending to be in a race. This 3 minutes is recorded on a video camera, as well as the green screen being chromakeyed out showing the child in a race on a big TV that draws the crowds. Straight afterwards the customer is given a DVD of their movie.
further spec needed:
I want high definition footage for the Movie on DVD
I want to be able to record this footage as it is being shot - 4-5minutes from when the child sits in the car to getting the DVD as to maximise income/hour.
I am wanting to know which software of the Production Premium CS 5.5 software will stream it live to the TV and record it on the DVD on the computer - I know that I can stream it to the TV and use a DVD Recorder to tape whats on the TV, but apparently that is unreliable.

Thanks for the reply Mylenium.
None, plain and simple. You are looking completely in the wrong place. And it's not even a mere software problem. As a minor, you would still need a capture card to stream the camera via HDMI or professional video signals (HD SDI, YCbCr Component etc.) to your computer. It's nothing you can do with any standard graphics card. Depending on what else you require, you would probably need more specific hardware like a NewTek Tricaster or whatever...
Ok. I then will break it up. Is there any Prod Prem cs5.5 software that will live stream the chromakey footage to the TV? Surely there is a way to have a live feed from the camera to the computer without the need for hardware and then software that will stream it out to the TV - Apparently Wirecast can do this - does Adobe not have something similar ? I am going to be building a Computer around the above intended use, so a P2 Card Reader was suggested. The budget is R8000, or $800 for the exerything except the monitor.
That's impossible. Per spec, DVD can only record SD PAL/ NTSC. For HD, you would need a BluRay recorder and that's gonna cost you, especially since for what you have in mind only the more expensive BD-RE will do what you want and due to the strict licensing rules, BD recorders are far and few inbetween and thus expensive...
Mylenium
Thanks Mylenium for the clear reasons for this, I need a quality that is not pixelated to be displayed on a TV at home when the people take their DVD home to view. Suggestions on resolution?
HAs anyone else got any low budget solutions?
Some Context: I am teaching myself everything in order to do this - unemployed and know i can make this work though. I have never been involved in the field before I got this idea so I have great gaps of knowledge here.

How can I change a green screen background?

Today I downloaded a trial version of PSE. This means of course that I'm new to the game. I can follow a step-by-step guide though. Here's what I'd like to do: I've taken a dozen photos of an actor with a green screen as a background. Is there a way that I can chroma-key out the green and put in another color, like gray or perhaps a textured off-white?
I wish I had a more challenging question. Maybe later on when I have a chance to play with the program I'll think up something difficult.

Please see http://www.essential-photoshop-elements.com/change-background-color.html

Imovie 9 green screen -- audio and video editing problems

I seem to have discovered that once you add a video (the "front" part) to a background using green screen, you can no longer do certain edits on the front part's audio or video.
I tried to do a manual audio fade on a certain clip, and it didn't work. Now I am trying to bring the entire audio for a certain clip down to zero, and even though the little speaker icon shows no sound waves, normal 100% sound is coming from the clip.
Likewise with the video. I tried to do a Split Clip on the front part and it simply didn't work.
Anybody have some words of wisdom? Thanks.

Thanks for the suggestion Brad, that makes sense... However, I was hoping there was a "straight" iMovie solution.
I'd prefer to not have to 1) spend any money and 2) use a program to do something iMovie is already supposed to do.

Creating green screen vids and overlaying them on Flash sites

I've heard of a thing where I can record a video in front of
a green screen and create a flash movie to overlay on a flash
website. It almost looks like the person is living and walking
around on the site. Can some one please give me more info on this
and the tools I need to make this. I feel like I'd need the Media
Server to serve this, but I'd use Premiere to edit video, right?
Thanks in advance.

Your thinking is correct. You'd use something like Premiere
to chroma key the green to a transparent background (I'm sure
there's a pile of tutorials out there), and encode to a Vp6 flv
(sorenson spark doesn't support alpha channel). Now you've got a
transparent video, and everything in your flash movie (at a lower
depth than that of your video object) will show through.
For delivery you could use FMS, but it wouldn't be a
requirement.You could just as well serve the video via http
(progressive).

Green Screen Background Matching Problem

I have been working on trying to match a background plate to a camera move with green screen elements. I need some help. Looking for someone who might be able to look at the project and give some advice (paid advice).

have spent a bit of time trying different ways of tracking this and none of them were spot on to be honest....
I have emailed to the contact link on your website the best I could get on my tracking programme - it is in a mulitplane node as I mentioned in a previous post.
Take a look - I only did a rough key - so basically what you should do is pull your key - switchmatte it with the original plate and plumb it in to the multiplane through the same input.
If you want to move the position of the BG plate inside the comp then the easiest way is with the move 2d node before multiplane - (you can do it inside but that can be a bit tricky)
BTW - for some reason PFHOE wouldnt accept the dimensions of your origial FG plate so I had to letterbox it to make it 1920x1080 - if you do the same then the track should match
I know its not a perfect result but it is by far the best I could get after trying Stabilizers and smoothcam. If you need better I would suggest trying to find someone with a full copy of PFrack or Bojou who may know a few more little tricks.
hope it helps

Green screen background

I understand how to create the green screen and how to mask it out...what I can not figure out how to do is add another background behind the person in the green screen. Is there a tutorial I can use? It seems so simple but what I found in the help section did not do a step by step how to....apparently, I need that! Please help someone...anyone???? Thanks!

Basically, you would place your "background" Clip on Video Track 1, and the green screen Clip on Video Track 2, then apply the Green Screen Effect to that Clip on Video Track 2, adjusting it for the green screen.
Here are some TUTORIALS, but I'm not sure which are specific to Premiere Elements. Still, the process is the same.
Steve Grisetti also covers Green Screen Keying in his PrE books, available at Muvipix.com. Not sure if he covers it in his Learning Series, or his Tips & Tricks section, also on Muvipix.
Good luck,
Hunt

Keynote..chat GREEN SCREEN background trick...

I noticed that with LEPORDS new ichat (video) you can place a movie or image in the background, when will this effect make ti to FCP and iLIFE??
This just about kills off Avid, ok, not really but if its in iCHAT it should be in iLIFE and FCP/FCE. Yes?

Everyone is right. Green-screen technology has been around a long time. Professional results can be achieved with minimal money and effort. Honestly, there is very little difference between a professional green screen and some cloth or paint you can get at any local store. As long as you use the basic principles (minimize spill off the background (green screen), keep a solid shade of color in the background, and keep the background color out of your subject - i.e., no green shirts in-front of the green-screen) and you'll do fine. Do some searches for green-screen tips, it's rather simple.
Honestly, if you're in the LA area, surely you know of someone who has access to some sort of studio. If not, local collages are a great place to start. I know for a fact that CSU Northridge has a huge green-screen studio that is RARELY used! Even though it is a horrible setup, it is constantly available and absolutely free. Networking never hurts, well... rarely. Responsible networking.
Hope this helps buddy and good luck with the music videos

Using 2 green screen clips and need to resize as one

I am using 2 green screen clips - one is a prop and the other shows kids. I have successfully loaded both into the Premiere timeline. I would like for the two to act as one so that I can resize them at the same time so I can zoom in on the kids. How do I link/group/??? them so they can be resized at the same time. Thanks in advance for any assistance.

Thank you. Nesting worked and allowed me to zoom in.
