if you want it to appear as if it has transparency ju= st create a solid underneath with a checkerboard effect.

If you are play= ing 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 ar= e seeing is a representation of the transparency grid that you see in an ap= p 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 t= he web. Then the product is delivered in a format that supports transparenc= y.

If you could download open one of the sample clips from a site like Sh= utterstock and you put that clip in an AE project or checked for an alpha c= hannel you would see that there is no transparency in the video.=C2=A0

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 beca= use there is nothing there to see. You would not see your desktop through t= he media player. That=E2=80=99s not how media players work.

I do not reca= ll ever seeing a desktop behind Quicktime Pro either. No video =3D no pixel= s =3D black background.

I hope this helps.=C2=A0
