This panel contains all audio-oriented parameters.
— Export audio: Turn this checkbox on to render the source audio, or audio that you’ve synchronized in DaVinci Resolve, along with the media being output by DaVinci Resolve.
— Format: You can choose which format of audio you want to render. Depending on which format you choose, different audio codec options will appear below.
— MXF OP1A(IMF): Generates media files that conform to the OP1a (Operational Pattern 1a) SMPTE 378M format of MXF media for file exchange.
— MXF OP-Atom: Generates media files that conform to the SMPTE 390M format of MXF media for file exchange.
— QuickTime: Exposes all available formats of audio compatible with QuickTime.
— MP4: Generates media in the MPEG-4 file format.
— WAVE: Generates media in the WAVE file format.
— MP3: Generates media in the MPEG-3 file format.
— Codec: Lets you choose between Linear PCM (the default), AAC audio, IEEE Float, or MP3. AAC audio encoding is only available on macOS.
— Sample Rate: Lets you set the sample rate, in Hz, of the output of the audio.
— Bit Rate Strategy: (Available for AAC encoding) You can choose among Constant Bit Rate, Average Bit Rate, Variable Bit Rate Constrained, and Variable Bit Rate.
— Quality: (Available for AAC encoding when Bit Rate Strategy is set to Variable Bit Rate) Five settings you trade between speed and quality when encoding AAC audio.
— Data Rate: (Available for AAC encoding when Bit Rate Strategy is set to Constant, Variable, or Variable Constrained) Lets you choose the maximum data rate for AAC encoding.
— Bit Depth: Lets you specify the bit depth at which to output the source audio.
— Render one track per channel checkbox: This checkbox lets you specify whether you want to export each channel as an individual track in the structure of the exported file. Multi-channel formats can be specified (2.0, 5.1, etc.), or can be output as flat multi-mono files.
— Render as discrete audio tracks checkbox: This checkbox is similar to the above, in that it still outputs one channel per track. However, discrete tracks have no positioning info, nor do they group as multi-channel clips (2.0, 5.1, etc.). For example, a mono file exported with Render one track per channel, comes in front and centered. The same file exported as a discrete audio track has no built in position information.
— Output Track #: This drop-down menu lets you choose which Main or Submix bus you want to output. A Plus button to the right lets you add additional tracks you want to export in this job, so if you want to export multiple Mains or multiple Subs, you can add more Track pop-ups.
— When you choose a track with multiple channels of audio, a field appears showing how many channels will be output; you have the option of using a virtual slider to change how many channels are output.
— In Single Clip Mode, when you choose “All Timeline Tracks, each audio track in the current timeline will be rendered as an individual track in the rendered media file you’re outputting.
Multi-channel tracks containing multi-channel clips will output audio tracks containing the same number of channels in the output media, which means you can output mixed combinations of mono, stereo, 5.1 or 7.1, and adaptive audio tracks, and each separately rendered audio track will reflect identical channel mappings.
