The first step is to remove the beginning and end of our own video material. The purpose of this step is usually to prevent our video material from being watermarked. Then, it is to find audio material and copy, which must be suitable for the situation and can sublimate the video we have mixed. The next step is to add transitions, special effects and filters to the video, and also according to your own needs. (As for editing, follow the recommended Pr, which will make the mixing smoother. )
In terms of mixed shots, if there are multiple films, the shots should be intrinsically related or similar to each other.
Learning mixed cropping can improve our aesthetic ability and composition ability, and then it is important to find our own learning methods. After all, practice is the only criterion for testing truth!
