You don’t have to share your number to get spam messages - I get weekly spam texts for “Susan” (not my name), which I never interact with but have been coming from random numbers for years.
Once your # is on a list, whether you put it there or not, it never leaves.
I’m the only one who has ever had this phone no., but if I were to swap now, 99% chance I’d get a reused number, which would probably come already loaded on a million different spam lists. There’s no winning.
GPU encoders like NVENC run their own algorithms that are optimized for graphics cards. The output it compatible with x265, but the encoder is not identical and there are far fewer options to tweak to optimize your video.
The output is orders of magnitude faster but (in my experience) objectively worse, introducing lots of artifacts
