How to Export Video with a Transparent Background in DaVinci Resolve

The short answer

DaVinci Resolve can export video with a transparent background, but only in a format that stores an alpha channel. Alpha is the extra layer of information that marks each pixel as opaque, transparent or partly transparent. In general terms, you open the Deliver page, choose an alpha-capable format and codec, such as QuickTime with Apple ProRes 4444, and turn on the Export Alpha option. Common delivery formats such as H.264 or H.265 in an MP4 container do not carry alpha. If you export to one of them, the transparent areas will usually be filled with black.

There is a second condition. The export can only contain transparency that exists in your timeline. If a background clip, a generator, or a key that never reaches the output fills the frame, the file will still be opaque even with Export Alpha enabled.

Evidence note: no version-specific documentation or test results were supplied for this guide. The menu names below describe Resolve's general workflow. Exact labels, codec availability, and differences between the free and Studio editions or between Windows, macOS and Linux should be checked in your installed version.

Formats that can carry transparency

Option | Carries alpha | Carries audio | Typical use

QuickTime – Apple ProRes 4444 / 4444 XQ | Yes, when Export Alpha is enabled | Yes | Overlays and keyed presenter clips for other editors

QuickTime or MXF – DNxHR 444 | Yes, when Export Alpha is enabled | Yes | Cross-platform editing workflows

QuickTime – GoPro CineForm (RGBA variants) | Yes, where offered | Yes | Intermediate files on systems where ProRes is unavailable

PNG, TIFF or EXR image sequence | Yes | No | Compositing, motion graphics, maximum compatibility

MP4 – H.264 / H.265 | Generally no | Yes | Final viewing copies, not transparent overlays

This table reflects general format capabilities. Whether a given codec appears in your codec list depends on your Resolve version, edition and operating system.

Step 1: Make sure the timeline actually contains transparency

• Remove or disable any background clip, solid color or generator underneath the element you want to keep.
• Empty areas of the frame, with nothing on any track below, are what export as transparent.
• If you keyed out a background on the Color page, for example a green screen behind a webcam recording, add an Alpha Output to the node graph. In the node editor, right-click and add it, then connect the key output of your keying node to it. Without this connection, the key affects the image but does not become transparency.
• If the transparency comes from Fusion, confirm that the alpha reaches the MediaOut node and is not flattened over a background node.

Step 2: Set up the render on the Deliver page

• 1. Open the Deliver page and choose the Custom render preset.
• 2. Under Video, set Format to QuickTime, or to an image-sequence format such as PNG or TIFF.
• 3. Set Codec to an alpha-capable option, such as Apple ProRes 4444.
• 4. Enable Export Alpha. This checkbox appears only when the selected codec supports alpha. If you cannot find it, the codec is the likely cause.
• 5. If an alpha mode choice is offered, pick premultiplied or straight to match what the receiving application expects. If you are unsure, check that application's import settings.
• 6. Set the render range to cover only the section you need, then click Add to Render Queue and Render All.

Step 3: Check that the export is really transparent

Many media players show alpha as black, so a black background on playback does not prove that the export failed. A more reliable check is to import the rendered file back into Resolve, or into the application that will use it, and place it on a track above another clip. If the lower clip shows through where the background used to be, the alpha channel is present. If the receiving application shows fringes or dark edges around the subject, try the other alpha mode (premultiplied or straight).

What this means for speech recorded on a webcam

A common reason to export with transparency is to reuse a keyed presenter clip, such as a webcam recording with the background removed, as an overlay in another project. In that case, the speech travels with the video only if the format can carry audio.

• QuickTime exports with ProRes, DNxHR or CineForm can include audio. Confirm that the Audio section of the render settings is enabled and that the intended tracks are included.
• Image sequences such as PNG or TIFF contain no audio. Render the speech separately as an audio file over the same range, and align it to the sequence in the destination project.
• Transparency settings do not change the audio itself. Any noise, echo or low level in the original webcam microphone recording will still be there after export. Fix those problems in the source recording or in Resolve's audio tools before rendering.

Gaps in this guide

No supplied evidence confirms exact menu paths for a particular Resolve release, which codecs each edition and platform offers, or how specific destination applications handle alpha. Treat those details as items to verify in your own setup rather than as fixed rules.
