Feature Request: Export RGBA (RGB + Alpha) instead of composited green background

[zar3160]

Hi! First of all, amazing work on this project — the temporal stability is excellent.

I’m integrating the output into a professional compositing pipeline (DaVinci Fusion / VR passthrough workflow), and I noticed that the current export composites the foreground over a green background before saving.

This causes color contamination on semi-transparent edges (hair, shoulders), since RGB gets premultiplied against the green background.

I wanted to ask:

Is there currently a way (or planned option) to export straight RGBA (RGB + alpha) instead of compositing over a background color?

Ideally something like:
• RGB foreground untouched
• Alpha channel preserved
• RGBA output (PNG sequence or ProRes 4444)

If not available, could you point me to where in the pipeline the compositing step happens so RGBA export could be added?

This would make the tool directly usable in professional compositing workflows.

Thanks again — the segmentation quality itself is already excellent.
