| If you are playing those movies in a media player on a website you are not seeing through the movies so the background of the website is showing through. What you are seeing is a representation of the transparency grid that you see in an app like Photoshop, Illustrator or After Effects. They create that grid as a graphic and put it at the bottom of the layer stack and render a file for the web. Then the product is delivered in a format that supports transparency. If you could download open one of the sample clips from a site like Shutterstock and you put that clip in an AE project or checked for an alpha channel you would see that there is no transparency in the video. If you purchased one of those clips with a transparent background and loaded it in any media player the transparent part of the clip would be black because there is nothing there to see. You would not see your desktop through the media player. That’s not how media players work. I do not recall ever seeing a desktop behind Quicktime Pro either. No video = no pixels = black background. I hope this helps. > On Mar 4, 2018, at 2:50 AM, Peter Matulavich <AE-List@media-motion.tv> wrote: > > Thanks everyone. Unfortunately I don't have QT Player 7 Pro to experiment, but even if I did, would I be able to save the movie so that the transparent checkerboard pattern would appear by someone playing the movie whose player was NOT set to those settings? I don't think I could, so let me rephrase my original question somewhat: I've seen movies being offered for sale on stock footage website (like Shutterstock) with those kinds of transparent backgrounds. According to the specs on the site, they are rendered in the Animation codec. When I click on the movies on that site, are they playing in Flash? How did the creators of those movies save movies with transparent backgrounds so that they can be seen by anyone clicking on the movies at that site? > > Pete > +---End of message---+ > To unsubscribe send any message to <ae-list-off@media-motion.tv> |
