Question about runtime video/audio recording and exporting

Hello, I've been looking for a way to record runtime gameplay (say, what a camera renders, with UI) and I've found some assets, and tested some of the free ones, the one that has gotten closer to what we look(recording audio and video from a camera and exporting to mp4) is VRCapture/VideoCapture from RockVR, but it seems they are no longer supporting this asset(?) as we can't find the PRO version to purchase it, we would like to export the video without the watermark

I know that Unity Recorder seems to do all we need but it's an editor only tool, is there a way to achieve this or an asset that can do this without much issue?

Thanks in advance for any help,
Kind regards
