DaVinci Resolve can render a timeline straight to MP3, and the control that does it is an Audio Format dropdown on the Deliver page that only appears after you turn video rendering off. This walkthrough follows Blackmagic's own DaVinci Resolve 21 Reference Manual, step by step — including the place where the manual contradicts itself about whether MP3 is available at all.
Before you start
Three things are worth knowing before you open the Deliver page.
MP3 is not what the Audio Only preset gives you by default. The manual describes that preset (p.4193) like this: "This preset is specifically for rendering an audio-only media file from the Timeline. Video rendering is disabled, and this preset defaults to rendering the Main 1 bus as a single clip, rendering one track per channel using the MXF OP-Atom format set to the Linear PCM codec, at 16-bits. However, the QuickTime, MP4, and WAV formats are also available, and you can also render 24- or 32-bit output."
Note what that list leaves out — more on that below.
Resolve's MP3 encoder is constant bit rate, full stop. In Blackmagic's Supported Formats and Codecs document (the July 2025 edition), the audio table gives "Mpeg audio / mp3" an Encode value of "Constant bit rate" — the same value under macOS, under Windows, and under Rocky Linux 8.6. There is no VBR MP3 coming out of Resolve.
Only four audio codecs can be written at all. That same table lists Encode values for exactly four rows: Linear PCM (wav), mp3, aac/m4a, and flac. AIFF, OPUS, AC-3 and u-law show "–" in the Encode column on all three platforms — Resolve reads them, it does not write them.
Step 1: Open Deliver and start from Custom
At the top of the Render Settings is the preset menu. The manual (p.4186) explains what picking one costs you: "Each preset automatically sets up what you need and locks you out of settings that are not necessary for rendering that type of media." The Custom entry is the one the manual describes as leaving nothing automatically set, with all conventional media rendering options available except those tied to a specific preset.
Step 2: Turn off Export Video
This is the step that reveals the dropdown you need. The manual's wording (p.4197) is exact about the side effect: "Export Video: Turn this checkbox on to render the source video. Turn this checkbox off if you want to render the source audio all by itself; this disables all video controls, and shows an Audio Format dropdown menu in the audio section of settings."
So the Audio Format menu is not hidden behind a preset — it is gated on Export Video being off. While you are there, confirm the neighbouring checkbox is on: "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."
Step 3: Choose MP3 in the Audio Format dropdown
The manual lists the full set of options for that dropdown on p.4205. The MP3 entry reads, verbatim: "MP3: Generates media in the MPEG-3 file format."
Yes — Blackmagic wrote "MPEG-3". That is the official text, quoted as printed. The same list also includes "FLAC: Generates media in the FLAC file format.", plus MXF OP1A(IMF), MXF OP-Atom, QuickTime, MP4 and WAVE.
Step 4: Check the Codec dropdown underneath
Separately from Format, there is a Codec control. The manual (p.4206) describes it as: "Codec: Lets you choose between Linear PCM (the default), AAC audio, IEEE Float, or MP3. AAC audio encoding is only available on macOS."
Two things follow. Linear PCM is the default, so an audio-only render left untouched will not be an MP3. And that macOS caveat is a live disagreement in Blackmagic's own paperwork — the codec list gives Windows an AAC Encode value of "CBR, VBR, average". The one point all the official documents agree on is that Rocky Linux has no AAC encoding at all. None of this restricts MP3, which carries the same Encode value on every platform.
Step 5: Set sample rate, bit depth, and the output bus
The manual documents these audio controls on p.4206: "Sample Rate: Lets you set the sample rate, in Hz, of the output of the audio." and "Bit Depth: Lets you specify the bit depth at which to output the source audio." It does not list which values appear in either menu, so check the official documentation rather than a number you read in a forum.
Pick your source with "Output Track #: This dropdown 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".
If you want one file rather than a stack of stems, leave "Render one track per channel" off — the manual says that checkbox "lets you specify whether you want to export each channel as an individual track in the structure of the exported file."
Then add the job to the Render Queue and render.
No Resolve install? Pull the MP3 out of an exported file instead
If the timeline is already exported, or you are on a machine without Resolve, extracting the audio from the finished video gets you the same MP3 without opening a project.
Try it right here
Runs in your browser. Your file is not uploaded anywhere.
This runs in your browser — the video is decoded locally and never uploaded. If what you have is a WAV that Resolve already rendered, WAV to MP3 handles the conversion step on its own, and extract audio from video covers the general case.
The contradiction worth knowing about
Both statements above come from the same chapter of the same manual:
- p.4193, describing the Audio Only preset: the alternatives to MXF OP-Atom are "the QuickTime, MP4, and WAV formats".
- p.4205, listing the Audio Format dropdown in full: MXF OP1A(IMF), MXF OP-Atom, QuickTime, MP4, WAVE, MP3, and FLAC.
The preset description omits two formats the dropdown documentation includes. That is the likeliest reason people conclude Resolve "can't export MP3" — they read the preset paragraph, not the dropdown reference. Blackmagic has not published a reconciliation of the two passages, so treat the dropdown list as the one describing the control itself, and check the official documentation if your build behaves differently.
Common mistakes
Hunting for an MP3 bitrate box. The manual's bit rate controls are scoped: "Bit Rate Strategy: (Available for AAC encoding)", "Quality: (Available for AAC encoding when Bit Rate Strategy is set to Variable Bit Rate)", and "Data Rate: (Available for AAC encoding when Bit Rate Strategy is set to Constant, Variable, or Variable Constrained)". All three say AAC. No MP3 bitrate values appear anywhere in the official documentation.
Rendering over your last export. The manual is blunt (p.4210): "When rendering a clip, DaVinci Resolve automatically overwrites any other media files that have the same name." The documented defence is the Use unique filenames option: "When enabled, additional characters are added to every rendered media file to guarantee that each rendered media file has a completely independent name."
Trying to use Single Clip mode with clip filtering on. Per p.4196: "IMPORTANT: Whenever clip filtering is enabled (via the dropdown menu to the right of the Clips button), Single Clip rendering cannot be selected."
Assuming loudness is handled for you. It is opt-in: "Audio Normalization: You can select loudness standard presets from the Audio tab in the Render settings on the Delivery page to automatically have the deliverable normalized accordingly."
FAQ
Can DaVinci Resolve export MP3? Yes. The Audio Format dropdown documented on p.4205 of the DaVinci Resolve 21 Reference Manual includes "MP3: Generates media in the MPEG-3 file format.", and the Codec menu on p.4206 lists MP3 alongside Linear PCM, AAC and IEEE Float.
Why do some guides say Resolve has no MP3 option? Because the manual's Audio Only preset paragraph (p.4193) names only QuickTime, MP4 and WAV as the alternative formats. The dropdown reference two pages later lists MP3 and FLAC as well. Same chapter, different lists.
What bitrate does Resolve's MP3 export use? Blackmagic does not publish a number. The Supported Formats and Codecs document says only "Constant bit rate", and the manual's data-rate controls are marked as AAC-only. Check the official documentation before assuming a value.
Can I export a VBR MP3 from DaVinci Resolve? No — the official codec table's Encode value for mp3 is "Constant bit rate" on macOS, Windows and Rocky Linux alike. VBR and average bit rate appear only on the AAC row.
Does exporting MP3 require DaVinci Resolve Studio? The mp3 row carries no Studio qualifier, unlike the Windows H.264 row ("More profiles and GPU acceleration in Studio"). The document's Studio-only notes single out other things: "Encoding video resolutions >= 4K is only supported with DaVinci Resolve Studio." and "Immersive audio formats are only supported with DaVinci Resolve Studio."
Should I export WAV and convert instead? If the audio is going into further editing, yes — the same table lists WAV as Linear PCM 16/24/32-bit. For a delivery file nobody will re-edit, render MP3 directly.
