About the H.264 for Blu-ray Disc Encoder Pane

This section contains detailed information about the elements of the H.264 for Blu-ray Disc Encoder pane in the Inspector window. You make your H.264 for Blu-ray Disc settings using this pane, by either modifying an existing setting or creating a new setting in the Settings tab.

The H.264 for Blu-ray Disc pane contains the following items.

  • File Extension field: Displays the H.264 for Blu-ray file extension (.264) automatically after the H.264 for Blu-ray output format is chosen from the File Format pop-up menu or the (+) pop-up menu in the Settings tab.
  • Allow Job Segmenting: This checkbox allows you to turn off job segmenting. It is relevant only if you are using Compressor with distributed processing and with multi-pass encoding. For more information, see Job Segmenting and Two-Pass or Multi-Pass Encoding.
  • Average Bit Rate slider and field: Choose an average bit rate to use for the output video with the slider, or enter a value directly. While the available range for a Blu-ray disc is between 5 Mbps and 30 Mbps, typical video bit rates with H.264 might range from 7 Mbps to 15 Mbps, depending on your DVD bit budget and the nature of your source media files. The available range for AVCHD discs is 5 Mbps to 15 Mbps.

  • Maximum Bit Rate slider and field: Choose a maximum bit rate between 6 Mbps and 35 Mbps for a Blu-ray disc, or between 6 Mbps and 17 Mbps for an AVCHD disc. You can also enter any number within these ranges into the accompanying field. The Maximum Bit Rate setting cannot be lower than the Average Bit Rate setting. As a general rule, set your maximum bit rate at least 1 Mbps higher than your average bit rate, to allow for bit-rate variability in achieving the goal of constant quality.
  • Multi-pass: Use this checkbox to turn on multi-pass encoding. Similar to two-pass MPEG-2 encoding, multi-pass offers the best possible quality. For faster (single-pass) encodes, turn this feature off by deselecting the checkbox. See Job Segmenting and Two-Pass or Multi-Pass Encoding for more information.
