• Frame Rate (fps) pop-up menu and field: Choose or enter a number to set the overall
frame rate of your output media file, or click the Automatic button to have Compressor
choose the frame rate.
• Key Frame Interval field: Enter a value to designate how often (number of frames) you
want key frames created in your output media file, or click the Automatic button to
have Compressor choose the key frame interval rate (the displayed value is 0 with
Automatic on; the actual value is determined during the encoding process).
• Multi-pass: Select this for higher-quality results but at the expense of longer encoding
times. This is only available when you choose an H.264 option from the “Video
compression” pop-up menu.
• Bit Rate slider and field: Move the slider to set the overall video bit rate for your output
media file, or enter a specific number in the accompanying field.
Audio Pane
You use the Audio pane to set the audio track quality, sample rate, quality, and bit rate
of the MPEG-4 output file.
Sample Rate pop-up
menu
Bit Rate slider
Use the following buttons and slider to make more detailed adjustments.
• Audio Enabled checkbox: Make sure that this checkbox is selected if you want the MPEG-4
Part 2 output format audio settings to be applied.
• Channels buttons: Choose the audio channel for your output media file to be either
mono or stereo.
• Mono: Choose this button for mono output.
• Stereo: Choose this button for stereo output.
• Sample Rate pop-up menu: Choose from one of the following sample rates: 8, 11.025,
12, 16, 22.05, 24, 32, 44.1, or 48 kHz. You can also choose Recommended to have
Compressor choose a sample rate that is suitable for the Channels and Bit Rate settings.
Note: If you choose Recommended, the sample rate is not determined until the
transcode actually starts.
• Quality pop-up menu: Choose one of the following for the audio quality of your output
media file:
• Low: This allows for fast transcoding, but it is at the expense of output file quality.
