In the connection part of two fragments, it is often connected in a transitional way, rather than directly splicing two rigid fragments together. Premiere provides as many as 75 special transition effects, and these colorful transition styles can be seen through the transition window.

Premiere, like Photoshop, supports the use of filters. Premiere*** provides nearly 80 kinds of filter effects, which can transform, blur, smooth, expose and texture images. In addition, you can also use filter plug-ins provided by third parties, such as FX software in Hollywood.

Usage of filter: Select the material to be processed in the timeline window, and then execute the Filter command under the Clip menu. Select the desired filter effect in the pop-up filter dialog window and click the "Add" button. If you double-click the filter in the left window, you can set and adjust the parameters of the selected filter.
