exporting video with an alpha channel (transparency)

You can export a file from Premiere Pro that includes an alpha channel (transparency).

In the case of FLV files, including the alpha channel just requires making sure that the Encode Alpha Channel box is checked.

QuickTime, AVI, and some other formats require you to specify the inclusion of an alpha channel from a color depth or channels menu. In some cases, a plus sign (as in Millions Of Colors+) denotes an alpha channel. In other cases, choosing to output to 32 bits per pixel implies the inclusion of the alpha channel; this refers to an output depth of 8 bits per channel for each of four channels: RGBA (where A is for alpha).

For general information about exporting, see “Workflow and overview for exporting”.

    This doesn’t work, the alpha channel is encoded but the resulting video is always yuva420p.

    It worked for me.
    Thanks A Huge lot. it didn’t occur to me that all I have to do is say 32 bits, but I was aware that 32 bits means that an alpha channel is present.
    Thanks again. God bless!!
