I am back using Max7 and haven't used it in years. I am working with a patch that generates visuals and I am looking to record some clips with the alpha channel ON.

I am using the animation Codec thinking it would solve the problem, but apparently every topic that I find on a similar subject leads me to a bunch of other issues or situations that doesn't solve my problems.

When I open the clips in Resolume, I can see that the Alpha channel isn't active.

Let me know if you can point me in the right direction.

When I open the clips in Resolume, I can see that the Alpha channel isn't active.
It is still a black background.

you should monitor the matrix output prior to the jit.record to make sure the alpha channel looks as expected.

you probably want to capture your geometry with a jit.gl.node @erase_color 0 0 0 0 to keep the background transparent.

and yes animation (if on windows using viddll engine) or prores4444 (if on mac using avf) are codecs that preserve alpha channel.

Weren't you working with Kurt Hentschlager?

I worked with him at SAT back in the days.
