    Hello,

    I need help!
    What is the Export setting for me to use alpha key in Premiere Pro to use in Unity for the AR?

    I am using windows 10 and everything says I need to use Quicktime.

    When I import using H.264 from Premiere Pro, the "Keep Alpha" is not checkable. Also, when I test my video, my character is playing, but the background is black.

    Does anyone know the settting to export from Premiere Pro?

    Thank you

    I don't think h264 supports alpha.
    Other encoders might, but I don't know if Unity supports those.
    Maybe you can just use a chroma key in Unity?

    Dev Dunk,

    Thank you for answering my question.

    I went ahead and used the chroma key in Unity and it does work, but I do not know how to get rid of the black bars. I will include a picture.

    Also, do you know why am I losing video quality when I use chroma key and what I can do to fix it?

    Instead of using green maybe use a blue not used in the video?
    And resize the plane to get rid of the black bars?
    Haven't don't this before, so cannot help much
