I made those bootanimations for my personal use but I thought to share them. They will work on any resolution, but they might be displayed too big or too small depending on your resolution. If you don't like the original size, you can resize them to your liking using the Boot Animation Factory Tool, that I also attached here because the links in the original thread are dead.
Main bootanimations  #1 - #2 - #3 - #4 - #5
Others  #1 - #2 - #3 - #4 - #5 - #6
1 - Download any bootanimation.zip
2 - Rename it to bootanimation.zip
3 - Using a file explorer like Root Explorer move the downloaded bootanimation.zip to your system/media folder
4 - Set the bootanimation.zip permissions to 644 (rw-r--r--)
5 - Reboot your phone
Note 1 - They work on AOSP/LOS and probably other roms.
Note 2 - They don't work on Samsung stock and Samsung stock based roms.
Note 3 - I don't take bootanimations requests.
Note 4 - You can request any bootanimation as flashable. Before requesting a flashable, please use the "search this thread" button. Your request probably already been done.
Special thanks to @PartimusPrime @despotovski01 and all the artists who made the animations
