If you need to perform general video editing, there are many professional software to choose from, such as Adobe Premiere Pro, Final Cut Pro (Mac), DaVinci Resolve (there is a free version) and other professional software. For simple editing, you can also use the video editor that comes with Windows, iMovie (Mac), or easier-to-use software such as movie editing. These tools all provide basic editing, transition, audio adjustment, and effect addition functions. Which software to choose mainly depends on the complexity of your editing needs, budget, and platform you use. Please note that no matter what software is used, relevant laws and regulations should be complied with to ensure that the content complies with local legal requirements and platform policies.
