![]() Playback at full quality will probably be in real time (but it might not be). Playback will play by rendering each frame just before the CTI reaches it. Yellow: This segment of the sequence does not have a rendered preview file associated with it.Playback at full quality is certain to be in real time. Playback will play using the rendered preview file. ![]() Green: This segment of the sequence has a rendered preview file associated with it.**OK, so now about those colored render bars…**With that preparatory definition out of the way, what do the colored bars mean? It can speed things up in some cases, so it may be useful for creating a rough preview in less time. ![]() Using preview files for final output will in almost all cases cause a decrease in quality. Preview files will not be used for final output unless you have Use Previews option checked on output-which you should not use except in the case of rough previews. Note: Rendering of previews is only for preview purposes. Don’t fall into the trap of using this general term to refer only to the specific case of rendering for the purpose of creating preview files for real-time playback. Rendering for display, rendering for final output, rendering for previews-these are all valid uses of the word rendering. The creation of these frames to be saved for rapid playback is what is meant by rendering a preview.īy the way, it’s common but confusing and misleading jargon to refer to rendering of previews as rendering all by itself. To play these frames in real time, they need to be processed and saved ahead of time, so that they can be read back and played instead of being recalculated on the fly. Premiere Pro caches these results so that it doesn’t unnecessarily redo work when you revisit a frame.įor more complex sets of effects and more difficult source media, Premiere Pro can’t always render the frames of the sequence as fast as needed to play them back in real time. In this case, each frame is rendered for display just before the CTI (current time indicator) reaches it. For Premiere Pro, this essentially refers to the creation of the frames in a sequence from the decoded source media for the clips, any transformations or interpretations done to fit the source media into a sequence, and the effects applied to the clips.įor clips based on simple source media that match the sequence settings and have only simple effects applied, Premiere Pro can render the frames that make up the sequence in real time. In the context of computer graphics, rendering is the creation of an image from a set of inputs. But what do the different colored render bars mean, and what does this mean for your work? What is rendering a preview?įirst, we need to understand what it means to render a preview. When you render a project, it means that Premiere Pro makes and stores a preview for the project behind the scenes. These colored bars are often referred to as render bars. If you’ve worked with Adobe Premiere Pro even a little bit, you’ve noticed that colored bars-red, yellow, and green-appear at the bottom of the time ruler at the top of the Timeline panel, above clips in a sequence. If you haven't, you should make sure that you originally set up your Premiere project with the correct resolution and frame rate, so it matches what you plan to export it in.What do the red, yellow, and green render bars mean in Adobe Premiere Pro? With these changes, your export dialog should resemble this (export file name, bitrate, and other settings may be different): You can uncheck the Lock and adjust each one manually if you need to.) (If Aspect Ratio Lock is on, the Frame Height may adjust automatically.
