Using Wax or Ulead Cool3D I produced animated 3d text on transparent background. The result can be an avi or a series of images in tga or bmp or png format. Although the avi or images have transparent background when they are placed on an overlay track in Vegas Studio they are not recognized as having transparent background. I tried switching off alpha in media properties screen of Vegas but this did not work. Could anybody facing a similar problem help please? Furthermore putting hundreds of images on the overlay track is not very practical. Is there another way of doing this assuming that the alpha channel can be switched off. I shall be much obliged for any help.
