How to use Overlay Mixer

    Question

  • Hi, guys,
    can you provide a example for me?
    thank you very much.
    I use gradedit.exe, I can add the overlay mixer to the graph, but i can't set the video size to 640*480 with 24bits. It said: Can't support this format. 
    i delete the overlay mixer from the graph, then i can set the video size to 640*480 with 24bits.
    why?

  • Did you try the various renderers available? Also it may need some color space conversion filter.

    What do you need the overlay mixer for? Why the VMR doesn't suit your need?


    If your application does not target Windows 2000 or older you should go with VMR.

  • Hi, androidi:

    my operating system is windows 2000, so i can't use the VMR.

    I want to use overlay mode to view the video. because i use preview mode to view the video, the video window isn't fluency enough.

  • VMR7 is available on Windows 2000 is it not?

    Why use 24 bit, no video cards support true 3 byte 24 bit any more.  Its all 24 bit in 32 bit form (DWORD).  Most all digitized video is compressed YUV based which is only good for about 16 bit color anyway.
