What's the difference between post-editing and post-editing? What software does each of you use?

Post-synthesis of film and television is mainly to combine a number of individual elements into a complete continuous dynamic picture. For example, you can import files output by other software into post-synthesis software, and add special effects or other files. Many scenes in the film are post-synthesized, and after deducting the background taken by the actors on the set, they are synthesized into the required scenes. There are many such softwares, but After effects are very useful and widely used in large companies all over the world.

Post-editing synthesis is mainly to edit the whole film, delete unused clips or adjust the required shots to the required time, and the order can be changed at will. For example, there are many scenes in the movie: memory flashes another picture and then switches back, etc., all of which need editing. There are many such softwares. Premiere is also made by a company with After effects, and it is also the world's top post-editing software.
