If you are looking for video editing tools, here are some you can use for basics:
Windows Movie Maker
IMovie
Then if you get more advanced and have a bit of money
Sony Vegas/ Movie Studio
Final Cut Pro X (or the express or Pro versions but they have been off market for a while)
Adobe Premiere
Audio Editing + Recording? No problem:
Audacity (free)
Adobe Audition (not free)
Visual Effects? You can do basic stuff in any editor from Imovie to Premiere. But if you are going for the proper stuff like masking, layering, detailed muzzle flares:
Adobe After Effects (not free)
Hitfilm (not free)
(there are others but they have slipped my mind atm).
3d models? Try these!
Blender (free)
Cinema 4d (not free)
