Want to create

Want to create this fast flash effect but still don't know how? First, import a photo and shorten it to around 0.1 seconds. Add a keyframe at the end. Then move to the beginning of the timeline and scale the photo up slightly. Next, duplicate the photo around 7 times. Use replace to swap all the duplicated photos with different images. After that, export the sequence and import it back into a new project. Open speed, choose normal and set it to around 1.5x. Then apply motion blur, setting the blur amount to 90 and the blend amount to 45. Next, duplicate the clip and choose reverse. After that, open, adjust and reduce the saturation to the minimum. At this point, you'll notice a slight pause in the middle because the reversed clip repeats the same frame at the transition point. Simply trim the end of the first clip and the beginning of the second clip. Now the transition becomes much smoother. Congratulations. Today you learned a Pangjiaqi flash effect.
