How to Fade Audio In and Out in DaVinci Resolve

DaVinci Resolve gives you several ways to fade audio, and the quickest one depends on where the volume change belongs. Drag a clip's fade handle for a simple fade at its edge. Add volume keyframes when the change starts or ends inside the clip. Put an audio crossfade on the cut when two clips need to overlap smoothly. Use Fairlight's batch fade commands when a pile of selected clips all need the same short cleanup.

Pick the method before you fiddle with duration. That keeps a small edit from turning into a full automation pass, and it stops you from using a crossfade where one clip should simply fade to silence.

Choose the right kind of audio fade

The difference matters. A fade handle changes one clip from its boundary. A keyframed envelope can start anywhere. A crossfade blends two clips around a cut. Automation records a moving fader over time and suits a broader mix move better than a single clip correction.

Method 1: use the clip fade handles

This is the fastest way to fade music in, fade ambience out, or take the hard start or stop off a clip.

1. Open the Edit page or the Fairlight page.
2. Make the audio track tall enough to see the waveform and the clip's top corners clearly.
3. Hover over the clip: the fade handles appear at its upper-left corner for a fade-in and its upper-right corner for a fade-out.
4. Drag the small handle toward the center of the clip. The shaded curve shows the fade region.
5. Play from before the fade through its endpoint, then drag the handle again to adjust the length. It moves in subframe increments if you need that precision.

Blackmagic's description is short: fade handles on the side of clips let you quickly add fade-ins and fade-outs. The DaVinci Resolve 21.1 Reference Manual confirms they work on both the Edit and Fairlight pages, so you don't need keyframes for a basic edge fade. Blackmagic’s Fairlight overview also puts clip gain, fade handles, keyframes and automation into the wider mixing workflow.

Adjust the shape, not only the duration

Once a fade exists, a second handle appears right on top of the fade curve. Drag it up or down to change the angle of the curve and left or right to change its shape. A straight-looking fade is predictable; a bowed curve keeps more level near one end and changes faster near the other. Double-clicking the curve handle resets the curve, and double-clicking the fade handle removes the fade.

No single curve is right for everything. With music, listen for whether the fade feels like a musical ending or like someone pulling a volume knob down. With room tone, listen for a sudden hole. With dialogue edits, the test is whether a consonant, breath or noise floor changes unnaturally.

Set the length by sound

A short fade can hide a click at an edit. A longer one can bring in or wrap up a music bed. Those are different jobs, so copying one duration across both rarely works. Start with the smallest fade that fixes the audible problem and lengthen it only if the transition still sounds abrupt.

Zoom into the timeline when the fade only has to cover a small transient. Zoom out when you're shaping a long musical entrance or exit. Same control, different useful scale.

Method 2: create a fade with volume keyframes

Use keyframes when the volume change has to start or finish away from the clip's edge. That's the better choice for dipping a music bed under one sentence, fading before the picture cut, or keeping a tail that runs past the visible edit.

1. Expand the audio track until the horizontal volume line is easy to grab.
2. Add a keyframe where the level should start changing. Hold the modifier and click the line: Alt-click on Windows and Linux, Option-click on macOS. You need at least two keyframes to create a change.
3. Add a second keyframe where the fade should end.
4. Drag the second point down for a fade-out, or up toward the normal level for a fade-in.
5. Add two more points if the level should stay lower for a section and then come back.

If your build or keyboard mapping uses a different modifier, open Resolve's keyboard customization and search for the keyframe action before you decide the shortcut is missing. What counts is the visible line and points.

When two keyframes are enough

Two points make one ramp. Put the first at the unchanged level and the second at the target level. That covers a fade that starts mid-clip and runs to its end.

When four keyframes are better

Four points make a temporary dip: normal level, ramp down, lower section, ramp back up. That's ducking done by hand. If you need the same response again and again under dialogue, the dedicated tools in our DaVinci Resolve audio ducking guide are easier to maintain. Keyframes still earn their place when the timing is unusual or you want to shape one passage yourself.

Use the Inspector for exact values

The timeline is the best place to line the change up against picture and waveform. The Inspector helps when you want to confirm clip volume or edit a selected keyframe more carefully. Blackmagic’s Edit page overview shows that you can animate a clip's settings with the diamond keyframe buttons in the Inspector, and the timeline volume line is the same clip-level control.

Don't confuse clip volume with the track fader. Clip keyframes travel with the clip. A track fader or automation pass works on the track at timeline positions and can affect whatever clips sit there later.

Method 3: crossfade between two audio clips

A crossfade belongs on a cut between clips. It lowers the outgoing clip while raising the incoming one across the same edit region. Use it to smooth room tone, ambience, dialogue takes or music edits where a hard cut exposes a sudden change. If Linked Selection is on and you put a video transition on an edit with linked audio, Resolve adds the audio crossfade for you.

1. Put the two audio clips on the same track so their edges meet.
2. Select the edit point between them.
3. Drag a Cross Fade from the audio transitions in the Effects Library, right-click the edit and pick one, or choose Timeline > Add Audio Only Transition (Shift-T).
4. Drag the transition's edges to change its duration, or double-click it to set Duration and Alignment in the Inspector.
5. Listen through the center of the transition for a dip, a bump, a phasey sound or a doubled transient.

Resolve ships three crossfades: Cross Fade +3 dB, Cross Fade -3 dB and Cross Fade 0 dB. They differ in how the power changes from one level to the other. Which one works depends on whether the clips contain related audio and whether the center sounds too loud or too quiet. The labels describe the math; your ears decide whether it suits the material.

Our broader DaVinci Resolve transitions guide covers adding, trimming and repairing transitions. With audio there's one extra question: do both clips have usable material beyond the visible cut?

Why a crossfade may refuse to extend

A transition needs media on both sides of the edit, and the manual only promises crossfades between clips that have enough handles. If one source clip starts at its very first recorded sample or ends at its last, Resolve has nothing hidden to overlap. Trim the edit to create handles, use a shorter crossfade, or put the clips on separate tracks and shape their edges independently.

Separate tracks are also clearer for an asymmetric overlap. The outgoing ambience can keep running while the incoming clip eases in, without forcing both sides into one centered transition.

Method 4: apply fades to multiple clips in Fairlight

When a timeline is full of dialogue clips with hard micro-cuts, adding every short edge fade by hand is slow and never quite consistent. Fairlight's Batch Fades window handles that for selected clips across several tracks.

1. Open the Fairlight page.
2. Select only the clips and tracks that should get the same treatment.
3. Open the Fairlight menu and review Batch Fade Settings.
4. Turn on the fade types you need (Fade In, Cross Fade, Fade Out), pick one of the six curves for each, and set the length in frames. Tick the overwrite box only if existing fades should be replaced. The Cross Fade box adds Equal Power, Equal Gain for material that could phase, and Unlinked for a different curve on each side.
5. Choose Apply Batch Fades from the Fairlight menu. Clips that don't touch get fade-ins and fade-outs; clips that are joined get crossfades.
6. Spot-check the busiest edit, the quietest edit, and any clip with a very short usable edge. If a clip lacks handles, Resolve warns you and lets you trim clips, skip them or cancel.

The window remembers its last settings, so after the first pass you can apply batch fades with one click from the Fairlight menu. That convenience is a starting pass, not a reason to skip listening. A setting that hides a click on one edit can swallow a consonant or soften a wanted transient on another.

What batch fades do not replace

Batch fades don't create one continuous fade across a whole program just because several clips are selected. For a long music fade that spans edits, keep the music in a stable track layout and use clip keyframes or Fairlight automation. For a broad mix move across several sources, use track or bus automation rather than stamping identical clip-edge shapes everywhere.

Use Fairlight automation for a performed mix move

Automation is the tool when you want to ride a fader while the timeline plays and keep that motion. Blackmagic's Fairlight page says the automation tools record changes to virtually any control setting or effect over time, so they adjust automatically during playback. It suits an evolving mix balance or a long passage with several adjustments.

Automation also carries more state than a clip fade. Before you record, check the automation mode, the enabled parameter and the track you're controlling. Afterward, switch back to a safe read mode so a stray move doesn't overwrite the pass. For a single entrance or exit, clip handles or keyframes are easier to inspect later.

Fix missing fade handles or a fade that does not work

The handles are not visible

Make the audio track taller and zoom in. Very short clips or collapsed tracks can hide the corner controls, and the handles only show while the pointer is over the clip. Make sure you're on the audio clip, not a linked video clip above it. If picture and sound need different edits, our guide to muting and splitting audio in DaVinci Resolve explains the basic clip relationship.

The wrong line moves

Resolve timelines can show several overlays. Check that the visible line is volume and not another parameter. If dragging moves the whole clip's level when you wanted one section, add keyframes first. If moving a mixer fader changes every clip on the track, you're working at track level, not clip level.

The fade sounds abrupt even when it looks long

Check the curve and the source material. A fade can span many frames while most of the audible change is squeezed near one end. Reshape the curve or move the endpoint. With dialogue and ambience, listen to the noise floor as well as the voice.

The crossfade creates a bump or hollow center

Shorten the overlap, try another crossfade type, or split the clips onto two tracks. Similar signals can reinforce or cancel each other around the center, and unrelated sounds can simply feel too busy together. A longer transition isn't automatically a smoother one.

A click remains at the edit

Move the edit away from the sharp transient, put a small fade on each side, and check whether one clip has an offset or a sudden waveform jump at the boundary. Use the shortest change that removes the click. A long fade can hide the defect while chewing up the start of the next word or sound.

Linked stereo channels behave unexpectedly

Confirm the clip attributes and channel format before you repair one side. A stereo clip, a dual-mono recording and a multichannel clip can expose different controls. Changing the interpretation after keyframing can also make the envelope harder to read, so settle the channel layout before the detailed fade pass.

A practical fade workflow

1. Name the boundary. Decide whether the change belongs at one clip edge, inside a clip, between two clips, or across a track.
2. Use the lightest control. Start with a handle, keyframes, a crossfade or batch fades, depending on that boundary.
3. Listen in context. Start playback before the transition and keep going past it. A fade judged from its isolated center can sound wrong in the sequence.
4. Check both ends. Make sure no consonant, breath, transient, reverb tail or room tone got cut too hard.
5. Spot-check after later edits. Trimming, slipping, relinking or changing clip speed can shift the useful material under a fade.

If you're still learning the timeline, the DaVinci Resolve beginner tutorial walks through the larger Edit page workflow. For this job, one rule does most of the work: where the change happens picks the tool. Clip edge means a handle, inside the clip means keyframes, between clips means a crossfade, and repeated cleanup means batch fades.
