Well... this is easily the best image quality for around the last 21 scenes, it just looks so much sharper and realistic with better frame rate and lighting and much more immersive 3D, the other 20 scenes don't have any depth to them.
I would take a guess that this was either filmed with an older setup or using older encoding specifications.
The last 20 scenes before this just don't look as good as they used to, and i suspect you're using a newer setup similar to what CzechVR use (which i PERSONALLY don't like).
The last 20...ish scenes just look fuzzy and soft focus, they don't look terrible, but definitely as step backwards.
Please stick with this setup / specs / lighting that you used to film this scene as it is far superior, i'm not bothered about the Sexbabes borders to the sides of the image if that is the issue.
Also i used to download the full original version which was typically around 20gb, but with the previous 20 scenes was up around 35gb so stopped downloading them - this scene is back to around 20gb for the full original file.
I've been meaning to say this for a while, but hoping the quality would improve, and for me this is the best image quality for a long time.
I have a feeling you won't listen to my feedback as you will have invested in newer equipment and want to use it, but i feel i have to mention it as i love the girls on this site and want to continue subbing.
All the best
