FX stands for the name of an effect you create in Premiere Pro. FX is also called plug-in effects. This is a type of plugin that lets you add special effects to a video or film clip. You can add special effects to video clips such as slow motion, blur, or distortion. You can also add special effects to audio clips such as volume changes, pitch changes, echo, flanger, reverb, chorus, and delay.
There are also effects that can modify camera movements like tilt, pan, zoom, dolly, and track. These effects are very useful when you want to make your premiere pro fx videos look more dramatic. You can create an FX plug-in by dragging one or more clips into the sequence and then selecting the Insert FX button. You can then add the effects you want to the clips in the timeline.
For example, if you want to make your clip appear to be moving slower than normal, you can select the Slow Motion FX plugin. You can adjust its settings in the Effects Control Panel. You can apply different speed settings to different parts of the clip, or you can apply one global setting to the whole clip. You can also change the color of the effects. For example, you can apply the same Slow Motion FX effect to several clips and then control the speed of each one separately.
