You may have seen websites that use transparent videos and wondered, “How did they do that?”
The subject is videotaped in front of a green screen. Adobe After Effects keys in green screen using a multitude of different encoding systems. After Effects uses the easiest and best encoding system on offer, called Keylight (1,2). After Effects then renders the alpha channel version of the video into FLV using the On2 VP6 codec format.
“This encoding method was used in the following films: Harry Potter and the Chamber of Secrets, Die Another Day, Blade 2, Resident Evil, Harry Potter and the Philosopher’s Stone, The Beach, Notting Hill, Sleepy Hollow, Chicken Run, Lost in Space, The Hudsucker Proxy, The Truman Show, Armaggeddon, The Big Lebowski, Mission Impossible, Last Action Hero, The Saint, Strange Days, Little Buddha, Waterworld, The Quick and the Dead and many, many more. “
Once you have used Adobe Keylight (1,2) to make the background transparent, you can use special software to render your video transparent. The transparent video lives in a layer called dhtml and the video shows the alpha channel video with no background. The website has been superseded by the fund. It is a good effect.
The video has no background, so you only see the topic. Actually, the background was either a green screen or a blue screen. After Effects is used to highlight or remove the background … you end up with just the subject or alpha channel.
You can edit your video meta tags within your web software to display a transparent video.
Although this is a more advanced video technique than simply uploading a video to YouTube. It’s worth it pretty well.
You can download Adobe AfterEffects software and try it for 30 days. Maybe you could even do what you need to have done in 30 days. It is worth taking the time to learn how to do this if you want to be on the cutting edge of website marketing.
