A have a huge repository of downloaded porn I am looking to clean-up/downsize; specifically, I have a lot of semi-duplicate videos, where I was able to find one source with a really high quality but low bitrate/FPS, others with lower FPS but higher bitrate, low quality but very high bitrate or FPS, etc. etc.
Obviously, I want to keep the versions that can give the best viewing experience and pleasure (no motion blur, skin detail, etc.). I am wondering how the three metrics affect video quality, which is the most important to keep high, and which I should prioritize when deleting duplicates (i.e., should I delete the one with lower FPS, or lower bitrate? Always prefer 1080p to higher FPS? 2160p but low FPS or 720p but high FPS?)...
Some other dilemmas I'm having: 24FPS vs. 30FPS, if/how high bitrate compensates for lower FPS, data rate vs total bitrate, bitrate vs video quality...
I'm a newbie to datahoarding, so try not to get too technical, but feel free to give me more considerations I should take into account.
Edit: also curious about what AV1 and h264 mean, and which file I should download from my source, if I have the option for one or the other.
