Hi everybody -
So here's my situation, I have an AVI movie of a person walking in front of a green screen. I took the AVI into After Effects, and took out the green background, and have created a transparent background. I have exported the file (yes, I made sure I clicked the Encode Alpha Channel to keep the transparency) in an FLV format. Now, when i import it into Captivate it doesn't keep the transparent background, it has a black background. BUT if I import it into Flash, it keeps the transparent background. Why is this? Can Captivate not handle this or do I need to change my format/click another option/something for it to appear with a transparent background?
The goal is to have the person walk onto the screen, welcome the watchers of the tutorial, and then walk off, so I need the background to be transparent. Is there another option or product I should use to create this FLV file?
Any thoughts or ideas would be great! Thanks in advance!!
Certainly this feature does work in Captivate 4. I know because in all the Captivate 4 classes I facilitated it was an exercise. So I'm guessing that it has something to do with the way your video was encoded. Odd that it would behave properly in Flash but not Captivate. This makes me wonder if it has something to do with your version of the Flash Player/Plug In. Perhaps try upgrading it?

Can you explain how you can import, transparent movies from after effects to captivate 5? I use the Keyligth in after effects to remove the background. Then I render as a flv movie, but when I import to captivate, I have a black background.
Can you help?
You have to do some specific things in After Effects to get it to work. But first, do you see it being transparent in AE after you take out the background? If not, make sure you are clicking the transparency grid button under the video in the composition window. Then you can make sure everything is transparent that needs to be in your video.
Under Composition, click Add to Render Queue, and on the Output Module, click the arrow, choose custom, and under the video output section change the channels: RGB + Alpha, Depth: Millions of colors+. Then choose your output and Render. Then once you take it into Captivate, throw something "behind" the video to make sure the background is gone.
Let me know if that doesn't work for you.
