3.4 is perfect

I am incredible happy with the settings for Quality Level the HIgh is with the max detail max decompress Recover original details 80 percent and Anti aliasing generates finally the movie I wanted on my 4K

Not only this the sound of the singing and guitar is nearly Unearthly good of the Gypsy music band of my mariage 30 years ago in hungary
The file is indeed 60 percent larger.
But Big is beautifull I would say

Last but not least I am very happy i can reverse read the settings from previous exports this saves me a lot of bookkkeeping

The code seems also faster or more optimized
