[Feature Request] Export PNG Overlays Only (No Video)

Hello.

I want to use another software to do my video encoding as I wish to have more control over output video. Re-encoding the VIRB Edit exported video degrades the quality. Plus, my video editor supports GPU acceleration for encoding and speeds up the process of rendering the new video.

Is it possible to skip the video export step and just export the transparent overlays so that I can import them as an image sequence? Or perhaps make some kind of a NULL-Encoder that just goes through the step of creating a 0 byte video file, then goes to the next step of exporting the PNG overlays?

Currently, it is very time consuming as the time taken for video export is very slow. Then having to discard that video because I prefer to work with the original recording from the camera...

Thanks!
