ADOBE PREMIERE PRO CS3 26 User Guide • Feet + Frames 35mm Reports time in feet and frames, assuming the frame rate of 35mm film: 16 frames per foot. Use for output to 35mm film. Feet + frames 35mm timecode showing "15" as highest possible number of frames before next foot • Frames Reports time solely in a running count of frames. Does not assign measurements of either time or spatial length. Use to output sequential stills such as those generated for an animation or DPX film editor. Frames timecode simply numbers each frame in sequential order. Note: When working with NTSC video assets, you should usually use 30 fps drop-frame timecode. This format conforms with the timecode base inherent in NTSC video footage and displays its duration most accurately. Title Safe Area Specifies how much of the frame edge to mark as a safe zone for titles, so that titles aren't cut off by television set overscan. A rectangle with cross hairs marks the title-safe zone when you click the Safe Margins button in the Source Monitor or Program Monitor. Titles are usually assumed to require a wider safe zone than action. Action Safe Area Specifies how much of the frame edge to mark as a safe zone for action so that action isn't cut off by television set overscan. A rectangle marks the action-safe zone when you click the Safe Margins button in the Source Monitor or Program Monitor. Sample Rate In general, higher rates provide better audio quality when you play back audio in sequences, but they require more disk space and processing. Resampling, or setting a different rate from the original audio, also requires additional processing time and affects the quality. Try to record audio at a high-quality sample rate, and capture audio at the rate at which it was recorded. Display Format Specifies whether audio time display is measured using audio samples or milliseconds. Display Format applies when Show Audio Time Units is selected in the Source Monitor or Program Monitor menu. (By default, time is displayed in frames, but it can be displayed in audio units for sample-level precision when you are editing audio.) Note: DV video and audio use standardized settings that are specified automatically when you select DV Playback editing mode. When you use DV Playback editing mode, avoid changing the Timebase, Frame Size, Pixel Aspect Ratio, Fields, and Sample Rate settings. Video Rendering settings Video Rendering settings determine the file format, compressor, and color depth Adobe Premiere Pro uses for preview files and playback of clips and sequences. Maximum Bit Depth Maximizes the color bit depth, up to 32 bpc, to include in video played back in sequences. This setting may not be available if the selected compressor provides only one option for bit depth. You can also specify an 8-bit (256-color) palette when preparing a video program for 8 bpc color playback, such as when using the Desktop editing mode for the web or for some presentation software. If your project will contain high-bit-depth assets generated by programs such as Adobe Photoshop, or high-definition camcorders, select Maximum Bit Depth to make Adobe Premiere Pro make use of all the color information in those assets when processing effects or generating preview files. Previews These options determine the file format, compressor, and color depth Adobe Premiere Pro uses for preview files and playback. Select a combination that gives the best quality previews while keeping rendering time and file size within tolerances acceptable for your system. For certain editing modes, these settings cannot be April 1, 2008
