• 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. Since the MPEG-4 Part 2 format uses single-pass VBR, you can leave this
checkbox selected in all cases for added speed gains with distributed processing. For
more information, see Job Segmenting and Two-Pass or Multi-Pass Encoding.
• Video, Audio, and Streaming buttons: These buttons open the Video, Audio, and
Streaming panes, described next.
• Enhanced Podcast (m4a file): Select this checkbox to ensure that podcasting annotations
and metadata are written to the output media file. This is available for audio files only.
To make this option available, deselect the Video Enabled checkbox at the top of the
Video pane.
• Fit marker images within: Use this to specify the width and height of the podcast marker
images when creating an audio podcast. You can also click the Automatic button to
have Compressor enter the values. This option is only available when the Video Enabled
checkbox at the top of the Video pane is deselected. See Stage 5: Creating and
Configuring Markers for the Output Media File for more information.
Video Pane
The Video pane allows you to make settings for the quality (ISMA profile), frames per
second (fps) rate, key frame interval, and bit rate of your MPEG-4 Part 2 output file.
Either enter a number in
the Bit Rate field or use
the slider to set the bit
rate.
The pane contains the following controls.
• Video Enabled checkbox: Make sure that this checkbox is selected if you want the MPEG-4
Part 2 output format video settings to be applied.
• Video compression: Choose the MPEG-4 compression format to use.
• MPEG-4 basic: Ensures playback on all MPEG-4 Part 2 devices.
• MPEG-4 improved: Gives better output quality, but this setting is not compatible with
older MPEG-4 Part 2 devices.
• H.264 main profile: Similar to the H.264 baseline profile but with support for
standard-definition video requirements.
• H.264 baseline profile: Primarily for videoconferencing and mobile applications.
