Thanks for sharing! I would suggest you to try recording or streaming directly to youtube with my plugin “HDR wireless live streaming”. It can record in HDR preview but also to save into H.265 encoding, and there is no limitation on video length. 4-5 hours long recordings reported to me. Im currently workimg even on an advanced plugin update. It’s not only for live streaming, but it can record much better dynamic range compared to inbuilt recorder. Need to add spatial metadata for now afterwards into mp4 file, before uploading to youtube.
