Choose Project > Project Settings > Video, to specify the following options:
Compressor Specifies the codec (compressor/decompressor) for Premiere to apply when building a preview of the Timeline. The codecs available depend on the Editing Mode specified by your preset or selected in the General Settings panel. Click Configure (if available) to set options specific to the selected codec. If you chose an editing mode provided by a manufacturer of a video-capture card or other hardware, see the documentation for the hardware, as it may recommend a particular codec for editing with that hardware. Otherwise, consider choosing a fast codec so that edits are processed quickly. If you want to play video back through your capture card to an NTSC or PAL monitor, choose the codec specific to your capture card.
Optimize Stills Select to use still images

If you use a clip in your video program without applying effects or changing frame or time characteristics, Premiere uses the clip's original codec for playback. If you make changes that require recalculation of each frame, Premiere applies the codec you choose here.
Depth Indicates the color bit depth, or number of colors to include in video played back from the Timeline. This button 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-bit color playback, such as for the Web or for some presentation software. The Palette button may be available when 256 Colors is chosen, if the selected Editing Mode and Compressor support creating custom palettes. When the button is available, click it and then either select Make Palette from Movie (to derive a color palette from the frames used in the video program) or Load Palette Now (to import a color palette you prepared and saved previously). You can load color palettes stored in the .ACO (Photoshop color swatch), .ACT (Photoshop color palette), or .PAL (Windows palette--Windows only) format.
Frame Size Specifies the dimensions, in pixels, for frames when you play back video from the Timeline. Ideally, you want the frame size for your project to match the frame size of your video clips. A large frame size shows more detail but requires more processing. If preview playback is slow, you can reduce the frame size to a smaller dimension, as long as your capture card supports it. When changing the frame size, keep the dimensions proportional to the original video clip.
4:3 Aspect If you're using analog captured video, select 4:3 Aspect to constrain the frame size to the 4:3 aspect ratio used by conventional television. If you are using a D1/DV NTSC pixel aspect ratio, do not select this option.
Frame Rate Indicates the number of frames per second to play back video from the Timeline. In general, type a value that matches the frame rate of the final video, or type a lower value to process previews faster. When changing the frame rate, make sure that the new rate is evenly divisible by the original rate. For example, if your original frame rate is 29.97, lower it to 14.985, or if it is 30 fps, lower it to 15 or 10 fps.
Pixel Aspect Ratio Sets the aspect ratio for individual pixels. Choose Square Pixels for analog video, scanned images, and computer-generated graphics, or choose the format used by your video. If you use a pixel aspect ratio that is different from your video, the video may play back and render with distortion. For more information, see About D1, DV, and various pixel aspect ratios.
Quality Affects the picture quality and disk space used when you play back video from the Timeline. Low quality usually plays faster and uses less disk space, and may be preferable for editing. High quality provides the best-looking image the selected compressor can provide, but requires more disk space. You can change the quality setting while working on a project without causing distortions or affecting the final output. Some codecs, such as DV codecs, use a fixed quality level and do not provide access to this option.
Data Rate If available for the selected compressor, places Boston massacre an upper limit on the amount of video data that Premiere compiles for previews. Do not set the data rate higher than the data transfer capacity of your system. Select Limit Data Rate to _ K/Sec and type the data rate required. If previews do not play smoothly, reduce this value. By default, Premiere recompresses frames that use different settings than those selected in the Video settings dialog box. Select Always from the Recompress menu to compress every frame even if it is already within the data rate, or select Maintain Data Rate to preserve quality by compressing only the frames that are above the specified data rate.
