Create a sequence with uncompressed video playback (Windows only)

For the highest quality previews of sequences on an SDI card or device connected to an external monitor, you should use one of the uncompressed formats for preview files. Uncompressed 8-bit (4:2:2 YUV) is particularly suitable for projects meant for SD output, while Uncompressed 10-bit (4:2:2 YUV) is best for projects meant for HD. Additionally, with Uncompressed 10-bit (4:2:2 YUV) and high bit-depth color rendering Adobe Premiere Pro will make use of the color information in 10-bit assets and will upsample other assets in a sequence to generate 10-bit preview files. Adobe Premiere Pro delivers the best preview performance when using these preview file formats on a system with a supported SD-SDI or HD-SDI card installed.

Both these uncompressed formats do subsample video files at 4:2:2 YUV, but unlike the other file formats available for preview files, they do not then run the video data through a compressor. They are called uncompressed because they do not add this second layer of compression, and thereby retain much higher color depth in the previews than the compressed formats. As a consequence, uncompressed preview files can be quite a bit larger than compressed preview files.

  1. Select File > New > Sequence.
  2. In the New Sequence dialog box, click the General tab.
  3. From the Editing Mode menu, choose Desktop.
  4. In the Timebase menu, choose the desired frame rate, such as 24, 25 or 29.97 frames/second.
  5. In the Video section, choose the desired settings for Frame Size, Pixel Aspect Ratio, Fields, and Display Format. For example, 1920 x 1080, Square Pixels (1.0), No Fields (Progressive Scan), and 30 fps Drop-Frame Timecode.
  6. In the Audio section choose the desired settings for Sample Rate and Display Format.
  7. In the Video Previews section, choose one of these sets of preview file formats and codecs, depending on your system:

    • For Windows, choose Preview File Format: Microsoft AVI and Codec: None (alternatively choose Uncompressed UYVY 422 8bit).

    • For Mac OS, choose Preview File Format: QuickTime and Codec: None (alternatively choose Uncompressed YUV 10 bit 4:2:2 or Uncompressed YUV 8 bit 4:2:2).

    You may see different file format and codec choices depending on your optional hardware capture/playback card.

  8. (Optional) Check the Maximum Bit Depth checkbox if your system supports 10-bit or greater formats.
  9. (Optional) If you plan to use uncompressed playback again, click Save Preset, give the preset a name and description, and click OK.
  10. Enter a name for the sequence and click OK.
