Export Pro Res 4444 with alpha layer . . .
-
Hello Troikatronix team,
I'm trying to export a movie with a transparent layer, which I understand in need to use Pro Res 4444 to accomplish. I see that I can export video in the Pro Res 4444, but nothing gets exported in the video. Even just exporting a movie of a simple shape (using the shape actor) in Pro Res 4444 shows nothing in the exported video.
Thoughts?

I just ran a test on my M1 Mac mini, with Sonoma, and I had no issue with the recording.
I set Record Stage Settings, to use quicktime, Prores 4444. I then started stage recording, set a location, and it started to record.
I then imported the file to test. It has a transparent background and plays well.
Note: the video feed to the projector actor must have a transparent background.. but this is what you would have be default simply connecting a shapes actor to it.

Thank you DusX,
You are correct. I now have the 'shapes' actor working properly.
However, I am using a GLSL Shader to create the video I want to use as a transparent image. And I think you've also helped me there as well, as the shader does not have a transparent background. I will consult ChatGPT to see if it can help me add one.
