By copying and pasting attributes, right-click the first clip with added effects in the timeline to select copy, then select other clips to right-click to select paste attributes, and only select video or audio effects to paste; 3. Use the adjustment layer to process the video effect, create a new adjustment layer and place it above the target clip, and drag the effect to the adjustment layer to affect all clips below it. The above methods can significantly improve work efficiency and are suitable for the needs of different scenarios.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages.
