Lesson 5. Transitions > Rendering transitions

Rendering transitions

Throughout this lesson you have been viewing transitions in real time. In other words, when you add a transition, you can play it back immediately to see if you like the effect. Based on your system or with more processor-intensive effects, you may note that the previews are not as smooth as you would want. This is often solved by a process called rendering which allows Premiere Elements to calculate each frame of your transition.

Look at each transition you have added in the timeline. Directly above the transition is a small red bar corresponding exactly to the length of the transition. This signals that these transitions have not been rendered.

Make sure the Timeline window is active by clicking on its top, and then press the Enter key. Premiere will automatically begin to render the Video preview of each transition. When the program is done rendering, it will automatically begin playing the project from the beginning.

Notice the red bar above each transition has changed to green. This is a visual cue that the transitions in this project have been rendered. Once a transition has been rendered, you do not need to render it again unless you change any of its properties.

If you were to save and close this file, and then reopen it, the green bar would still be there.


You are not required to render your transitions. Rendering is an optional process useful for previewing your transitions as they will appear in the final exported movie.

GPU (Graphics Processing Unit) Transition Effects

Based on your computer system, you may have additional Effects available to you.

If you have a PCI-based video card, you likely have a GPU (Graphics Processing Unit). (Laptops and motherboard-based video cards may not support a GPU). If your GPU supports Direct3D, Pixel Shader (PS) 1.3/1.4, and Vertex Shader (VS) 1.1 (see your video card specifications for information on GPU and supported components), you can use three special effects that take advantage of the added video processing capabilities of GPU cards and of 3D shading. These effects are Ripple (Circular), Page Curl, and Refraction, and they reside in the GPU Effects folder in the Effects palette. All these effects provide added three-dimensional realism to your image.
