Premiere Pro attempts to play back any sequence in real time and at full frame rate. Premiere Pro usually achieves this for all sections that either
need no rendering or for which Premiere Pro already has rendered preview files. However, real-time, full frame-rate playback is not always
possible for complex sections without preview files: unrendered sections.

To play back complex sections in real time and at full frame rate, you may have to first render preview files for those sections. Premiere Pro marks
unrendered sections of a sequence with colored render bars. A red render bar appearing in the time ruler of a sequence indicates an unrendered
section that probably must be rendered in order to play back in real time and at full frame rate. A yellow render bar indicates an unrendered
section that probably does not need to be rendered in order to play back in real time and at full frame rate. Regardless of their preview quality,
sections under either red or yellow render bars should be rendered before you export them to tape. A green render bar indicates a section that
already has rendered preview files associated with it.

Sequences refer to preview files in much the same way as source media. If you move or delete preview files in the Windows or Mac 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.

You can customize a sequence preset to allow previewing of uncompressed 10-bit or uncompressed 8-bit footage. For more information, see
Create a sequence with uncompressed video playback.

FAQ "Why is there a red or yellow bar in my sequence?"

See this article

for details about what red, yellow, and green render bars mean and how they relate to playback and rendering previews.

See this blog post

for information about RED Rocket support in Premiere Pro CS5 (5.0.2), which accelerates processing of RED (R3D) media.

Define the work area for rendering

Do any of the following:

Drag the work area bar over the section you want to preview. Make sure that you drag the work area bar from its textured center; otherwise
you cue the playhead instead.

Grabbing the work area bar (above) and dragging it over the section to preview (below)

Drag the work area markers (at either end of the work area bar) to specify the beginning and end of the work area.
