What is the best way to learn VFX?
VFX on a phone is much different than actually doing it on a computer. You might want to take stepping stones to VFX and start by editing videos with a NLE. One of my favorites is Premiere Pro (though, it's been buggy lately). Once you learn how to edit videos, you can then move onto VFX with Adobe After Effects, or Hitfilm for more simpler stuff.
