>Yes, encode to h265, encode rf=25 10-bit. They take a long time to encode but I just leave my computer on all day to do it and the space savings are worth it

You are absolutely braindead if you think that rf25 is "no drop in quality that my eye can perceive."
Maybe on a 14" laptop monitor, on bad looking JAVs, it's not going to matter.
On any crisp video, it's going to absolutely destroy it for collection purposes.

RF20 to RF22 on Slow preset for preservation. The Slow speed is absolutely necessary. If you insist on using RF25, try it on the Slow Preset and you'll get the equivalent of better than RF22 Fast quality
