I have the need to use a lot of green screen video on the
Web. I was wondering if anyone is aware of any tutorials that
describe how to do this?
Thanks,

Can't get Transparent background in Adobe Flash Professional CS4

I'm wanting to create a moving object that will be exported into a tv commercial.
Object has already been created in Adobe Illustrator, and now will be dropped into flash for adding movement.
The destination commercial will be created in Sony Vegas, with the settings of (Australian) PAL television (25 fps, 576x720 pixels, lower field first).
Thus keeping it simple, I want to set Adobe flash with the same output format, meaning that the canvas will have to be 576x720 pixels at 25 fps. So far this seems to have worked okay.
Now I'm wanting to get rid of the canvas colour, just like I have here in this photoshop screen shot.
Judging by the colour palette in Flash Professional, it looks like it can't be done. I've checked "transparent palette" through yahoo and google, and had no results. The adobe documentation only details how to remove a background in Photoshop.
Can someone please inform me how to get transparent background in Adobe Flash Professional CS4. Thanks

As far as I know there is no option to set up a file with a transparent background in design mode. A transparent background is normally realized in the embedding code of an html web page that displays the Flash file (using wmode="transparent" as a parameter).

Transparent background video object

How to create transparent background video?

I'm trying to add some filters to some some imported text files from Photoshop, but they don't work so well so I need to import them as transparent video files. So, how do I export the text as a ProRes file from FCP with a transparent background so I can re-import it and add the video filters?
I've tried fiddling around with the alpha channels but the background always seems to be black.

You don't export the files as a ProRes clip.
Place your text on a transparent background and export from PS as .tiff or .png stills. They will composite automatically. You can set the default length required in FCP's User Preferences...
You must do this before you import the files.

Transparent background in Captivate Flash movie on all slides

hi im trying to make background transparent, and I've achieved it in first slide of presentation, but when slide changes the background changes to white.
Im using transparent png as tile in stage background and changed parameter in html file - so.addParam("wmode", "transparent");
The presentation is in:
http://intersiec.com.pl/captivate/index.html
The source file:
http://intersiec.com.pl/captivate/szkolenie.cptx
Can You help me make whole presentation background transparent?
Best regards,
Kamil

Hi Erik
The fact so much time has passed since your first post would seem to indicate you have managed to stump all of us. LOL
I know way back around Captivate 1, 2 or 3 I would play with creating a transparent background, but I also recall that one of the versions seems to have unfortunately broken that.
Frankly, I'm surprised you are able to coax the initial load to be transparent. And about the only think I can think of to suggest here is to look at the properties for slide 2 forward and see what's different between them and the first slide. Master Page? Maybe by doing that you will find the "secret sauce". If you do, please share!
Cheers... Rick

Transparent Background- Flash Movie

Reposition element and transparent background

I am trying to reposition a flash element.
Go to www.newtechnologies2000.com/badgeflash2.html.
I would like the badge and the cup in the center to be centered in the blue flash background. Cannot figure out how to do it.
Also, I would like the blue flash background to be transparent, so the web page can showup around the badge.
How can I do this?
I have attached the .fla and .swf.
EDIT-I was able to reposiiton the element, not sure why what I did earleir did not work. Still need to know how to have a transparent background on the flash.

click file/publish settings/html and set "window mode" for transparent windowless.

Importing video into Flash --- can I get a Transparent background?

I am using Flash CS3. I am importing a Quicktime video into
Flash through File > Import > Import Video.
Here's the problem, though. I need this video to be
transparent. It appears that all videos imported into this method
have a black background. It makes sense, because usually the video
fills out the entire black area. However, with a video that needs
to be transparent, the black background shows through.
This movie will basically lay over a webpage, so the content,
graphics of the site would be visible behind the video.
What I'm trying to accomplish is very similar to what you see
at the bottom of this page:
http://rovion.com/Showcase/1800Flowers_demo.htm
We've worked out the technology, however using the File >
Import > Import video method adds a black background to the
Flash file, rendering it solid, not transparent.
Is there a way to remove this so the transparency is active?
Thanks for any advice.
Mark

Mark,
If the video was created with an alpha channel
(transparency) then you have to choose the option to import the
alpha channel in the video import wizard. If there is not an alpha
channel, then you will get the black box. It might be possible to
make the video a movie clip, and play around with the blend of it,
but I don't think you'll have much luck. So, your first step is to
figure out if the video was created and an alpha channel, then make
sure you have the option selected when importing.

Export Flash Video With Transparent Background

Is it possible to export an After Effects Comp to a Flash Video with a transparent background?
I have made a simple animation with no background. I'd like to export the Flash Video to go on a web site. I'd like to keep the background transparent.
Can this be done, and is there a checklist of what I need to select in "Make Movie"?
Thanks!

from "Render and export a composition as an FLV or F4V file":
"To include the alpha channel in the FLV output, use the On2 VP6 codec and select Encode Alpha Channel in the Video tab of the export settings dialog box."

How do I save stock footage as flash file with transparent background?

Hi
I have some stock footage of smoke on a black background (.mov format) that I would like to convert to a flash file with a transparent background, which I will be overlaying over a PNG image on a webpage.
I have managed to remove the black background in After Effects using a plugin called UnMult, but when I try to render as a FLV file in AE, even though I check the option to preserve the alpha channel and encode using the On2 VP6 codec, I still get a black background.
So I am wondering what else to try, whether it be with AE or Flash CS4. Is there a way of achieving this effect by directly importing the MOV file into Flash CS4 and removing the black background there, or do I have to use AE, and if so, how to achieve the effect I am looking for?
I would be grateful for any help in getting this together
Thanks
Nick

You can put the video file in a movie clip and change it's
blending in the properties panel to multiply or screen.

Rendering transparent background for website video

I have a comp for a website that I'm doing.
I have a transparent background and some fading in WHITE text with a light ray animated behind it.
I have followed instructions on how to render with the transparency intact (Quicktime, PNG, RGB+Alpha, Millions of Colors+). When I render it out and watch it in Quicktime, the light ray isn't correct and there's no transparency. Same thing with Final Cut Pro.
When I bring the footage back into AE, the transparency is there so I'm assuming that the transparency is there but QT & FC just don't play transparency files.
I need the transparency bc I want the text to reveal over a background picture I have in my webpage design.
Is there anyway to get this done right? I need the file to NOT be 300+ megabytes and when I drag the clip into COMPRESSOR to make it smaller, nothing is showing on the preview screen. I've been doing some research but haven't found anything to make it work correctly.
Can someone help me with this?
In the end, what I'm attempting to do is add the QT video into my iWeb page and have it play. I'm not a coder so I don't know how to make this happen any other way than making a QT movie and then adding it iWeb.
thanks in advance.

The only video format that supports transparency in a web browser is a flash player. That really doesn't fully support transparency either. The QuickTime player or any other video player will never ever support transparency in a web browser. Your project design is flawed from the outset. Another words you cannot do what you are trying to do using QuickTime. You will have to redesign for flash. If you redesign with flash, then you will not have a mobile compatible application.
I don't have much of an explanation of what you are trying to accomplish with your project so I can't give you more pointers than that. Point us to a website that has the features you are trying to implement on your webpage and maybe we can give you some ideas but After Effects is not where you should be looking.

Flash exe with transparent background

Hi,
   Is there a way to project an EXE with transparent background from flash (only using flash).
If not only flash,
      then what else should I use??
As I know there are softwares like NorthCode, Zinc, etc., But all of them affects the script in some way like "fscommand("quit");, loadMovie();" does not seem working.
What I exactly need is:
1) Flash projector (EXE as well as APP) with transparent background
2) I need to loadMovie (call exteranl swfs) into the main projector file.
      "note:The external swfs are FlashPaper files, so I should I have access to API, so that I could resize them, edit UI as I want."
Thanks in Advance.

Video with Transparent background

Hi I am trying to create a video through Adobe Premiere Elemements 10 that has a transparent background.
I need it to be in .FLV, .SWF or .MP4 format.
I have created the alpha etc but i think i am not exporting it correctly.
Can anyone explain the steps for creating the video with transparent background and how to export it for those file types please?
thanks.

I've not used the software, as I said a quick google threw it up. From looking at their further screens (http://www.increditools.com/flash_video_studio/features.php#flash8alpha) and (http://www.increditools.com/flash_video_studio/samples.php#flash8alpha) a probable workflow would be to create an original in PRE against your green screen and export this as DV (for standard resolution) or HDV (for HiDef). Once in the Flash software it is probably then just a case of using an eyedropper to turn your green screen transparent.
However your best option would be to install it and play around. Looking at their FAQ, similarly to the PRE trial, it installs as a trial version that will place a watermark across your finished video.
If you do try it out please be sure to post back here about its effectiveness - it may help others.

Video cutout with transparent background

I am new to finalcut and am wondering how I would go about creating my green screen movies like the following link ... I am looking to place video snippets on top of customers websites, we have the video shooting, green screen backdrop and apple products in place .. just cant find any tutorials to do chroma keying or rotoscoping with a transparent background.
Please help ... If there is another application I would need please do tell ..
I currently have Final Cut Express 4 !!!
link to video sample: video will load in bottom right ... http://www.innovateads.com/iads/demo.php?url=www.jtdesigns.com&submit.x=51&submi t.y=10

Tom:
Thank you for the reply.
I am obviously missing something, or have the wrong workflow....
I have tried cropping, but when I export, I still get a widescreen, with me in the middle third, and the two sides around me "cropped out".
How do I get it to save just the middle third?
There is a way to crop when I export to FLV, but no one seems to have success with this.
I keep getting a beachball/program not responding.
So my workflow should be?:
(1) use camera to record
(2) log and transfer into FCE - works (get widescreen)
(3) chroma key - works
(4) crop - I can crop out what I don't want
(6) save/export - ?? how/what am I missing here....to get only the middle third
(7) export to FLV - encode alpha channel
Appreciate any help you can provide.

Is it possible to have video with a transparent background in dps?

Is it possible to have video with a transparent background in dps?. Basically i've animated some elements in apple motion and want to incorporate them as an overlay (with the indesign page background showing through).

You could do it with an image sequence but AFAIK there’s no support for alpha channels in video.
