Previewing sequences About previewing sequences Adobe Premiere Pro renders a sequence when you play back the sequence in the Program Monitor. Sequences that consist of cuts between single tracks of video and audio render quickly, whereas sequences that include layered video and audio and complex effects require more processing time. When you set the Program Monitor's Quality setting to Automatic, Adobe Premiere Pro dynamically adjusts video quality and frame rate in order to preview the sequence in real time. During particularly complex sections of the sequence, or when using a system with inadequate resources, the playback quality degrades gracefully. You can customize a project preset to allow previewing of uncompressed 10-bit or uncompressed 8-bit footage. For more information, see Create a Project with Uncompressed Video Playback (Windows only). Areas that can't be played at the project's full frame rate are indicated by a red line in the time ruler. To play these areas, you can set the time ruler's work area bar over the red preview indicator and render a preview file. This renders the segment as a new file on the hard drive, which Adobe Premiere Pro can play at the project's full frame rate. In the Timeline panel, rendered areas are marked with a green line. Note: Projects refer to preview files in much the same way as source media. If you move or delete preview files in the Windows file browser rather than the Project panel, you'll be prompted to find or skip the preview files the next time you open the project.
