Overlays with Alpha Channel Not Showing

PostMon Mar 30, 2020 8:18 pm

I have the ATEM Television Studio Pro 4K switcher. Everything works great until I try to do an overlay with an Alpha channel. I have been unable to get any graphic to show. I'm sure it is just a step that I am missing.

Any advice?

Thanks,

ATEM control software: Media tab: Find the file: put it in one of the Stills boxes: Assign it to a Media Player: it show black with the graphic

When I go back to the Switcher, and push MP1 the graphic comes up with a white background. It is like it doesn't recognize the Alpha Channel.

Thank you for your reply.

Hello Simon. To verify that the graphic has an alpha channel look at the Media player key image. You should see white where the graphic is and black everywhere else. If it is not that, then the alpha channel is incorrect or missing. You should use Targa or PNG files with alpha uncompressed.

I hope this helps. Regards, Gary

Thank you. I was skipping the DSK part. It is working now.
