For a graphic with an alpha channel, you can use a 32-bit bmp file or a 32-bit
Photoshop psd file. A 32 bit bmp sample and a Photoshop psd file that shows
how this bmp file was created is located in the Overlays folder in your Stream
directory. Note that the 32-bit bmp file does use the alpha channel in the file to
determine the transparency for the graphic overlay. However, if you use a
Photoshop file the transparency in the file will be used to determine the
transparency for the graphic overlay and NOT the alpha channel in the
Photoshop file.
Graphic overlay files must be created with the graphic sized and positioned
properly for the your encoding session. Graphics cannot be sized or positioned
within the TouchStream interface.
To select the graphic overlay file press the thumbnail region at the bottom left
hand corner.
Set the ―Fade Amount‖ or the maximum opacity of the overlay (what it will look
like when it has finished the ―Fade In‖). Set the ―Fade Duration‖, or the time it will
Press the thumbnail region to
select the graphic overlay.
