A convincing clone effect is mostly decided on set: two performances with the same camera position, exposure, focus and lighting. In DaVinci Resolve, my default is the easiest version: two stacked takes and one fixed crop. Bring in a maintained matte only when the performances cross, and use Fusion tracking only when the camera movement repeats closely enough to line both takes up.
Quick answer: if your clones stand on opposite sides of a locked frame and never overlap, stack two takes on separate tracks and crop the upper clip at the split line so the lower take shows through. No drawn mask, no Magic Mask, no Studio license.
Save Magic Mask or a Power Window for clones that cross paths, share the middle of the frame, or move through a changing outline.
Before You Film Yourself Twice for a DaVinci Resolve Clone Effect
Put the camera on a tripod and leave its position, focal length and focus alone between takes. Even a small bump can misalign background edges across the split. Before you move anything, record a few seconds of the empty scene; that clean plate gives you background pixels for repairs later.
Set exposure and white balance manually on the camera before the first take, too. Auto white balance that drifts between takes is a real problem, and it shows up as a visible seam exactly where your clones meet.
Grab a few seconds of room tone before and after each performance, and mark a clap, a spoken cue or a hand signal at the exact moment one clone has to react to the other. Once you're editing, trim both clips to that cue.
Matching clip lengths won't keep two takes in sync on their own. What keeps them in sync is trimming both clips to the same reference moment, whatever the raw duration of either one.
For the crop method, mark a separate floor spot for each performance. Keep hands, props and their shadows away from the planned split, and avoid moving curtains or fans in the background. If the clones interact, rehearse the timing and decide which clone or prop passes in front.
Free Method: The Resolve Split-Screen Clone Effect
The simplest version needs no drawn mask, no AI isolation and no frame-by-frame rotoscoping. If your clones never cross a fixed line in the frame, this is the whole technique:
- Put your clean base take on the bottom video track, V1.
- Put your second take directly above it on V2.
- Select the V2 clip on the Edit page and open Inspector > Video > Cropping. If the clone you want from V2 is on the right, raise Crop Left until V1 shows through on the left; use Crop Right for the opposite layout. Leave Composite Mode at Normal and Opacity at 100 while you build the split.
- If the seam shows under your lighting, add a little Softness in the Cropping section to blur the edge instead of leaving a hard line.
For a locked-off shot, this method never leaves the Edit page and works in Resolve Free. The Inspector's Crop Left, Right, Top and Bottom controls create transparency, which is what lets the lower V1 take show through.
To check alignment, drop V2 opacity for a moment and compare the fixed background edges, then put it back to 100. A half-transparent mix isn't a finished clone. Line up the interaction cue rather than just the clip starts, and mute the take audio you aren't using so room tone and spoken cues don't double up.
The Resolve 21.1 Reference Manual defines negative Softness as feathering inside the crop box and positive Softness as feathering outside it. Use just enough to hide a minor boundary. Softness can't repair a different camera position, a changing shadow or moving background detail.
This only holds up while each clone stays on its own side of the line. The moment one of you reaches across it, you're into real masking, which is next.
Studio Method: Magic Mask for a Resolve Clone Effect
In Resolve 21.1, the Color-page Magic Mask 2 is a Studio feature, not a Resolve Free tool; Blackmagic lists it on the Studio feature page. Use it when the upper clone needs a changing subject outline, and leave the base take alone unless it needs isolating too.
Magic Mask 2 builds the selection from Add and Subtract clicks. There are no separate Person and Object modes anymore. The older stroke-driven tool is still there as Legacy Object Mask, but it isn't the default workflow now.
- Keep the base performance on V1 and the take you're isolating on V2. On the Color page, select that V2 clip and add a Serial node for its matte. Make sure the right take is selected before you start the mask.
- Go to a frame where your whole outline is visible and unobstructed, which isn't necessarily the first frame of the clip. Open the Magic Mask palette and click once on yourself in the Viewer to add a point. Add or subtract more points only where the mask misses you or grabs background it shouldn't.
- Set Quality to Better if the edge needs more detail, then track forward and backward from that reference frame across the range you need. A forward track from the middle never analyzes the earlier frames. Play the whole matte and fix the failures before you accept it.
- Right-click an empty area of the node graph and choose Add Alpha Output, then connect the node's blue key output to the blue Alpha Output connector, so the mask carries transparency instead of a color correction.
- If playback still needs relief once the matte is approved, choose Render in Place Magic Mask from the palette's three-dot menu and pick a location for the cached frames. The manual’s external-matte instructions describe this optional step. Keep those files with the project and render them again when source timing or the approved mask changes. Don't confuse it with the Edit-page Render in Place command.
For click placement, fixing the first failure, matte finesse and the external-matte command, use the full Magic Mask 2 workflow. This page stays focused on how that matte fits into the clone composite.
I'd isolate only the extra takes that really need their own matte. Several live masks can drag playback down, and rendering a mask won't fix a bad edge. If the composite is still sluggish after caching, the DaVinci Resolve slow playback guide walks through GPU and cache limits.
The broader Resolve 21 AI tools guide shows where Magic Mask sits among the other Neural Engine features, if you want the full picture before you decide on Studio.
Free Method: Power Window and Tracker Masking
The free version skips Magic Mask, but not masking. Power Windows and the Tracker palette are in every version of DaVinci Resolve, Studio or not, according to Blackmagic's Color page feature rundown. What they can't do is Magic Mask's actual job.
A Power Window defines a shape. The Tracker can move, rotate and scale that shape to follow something through the frame. Neither one turns your shape into an outline that reshapes itself around a moving arm or a turning body.
When your outline changes, you move the window's points by hand at the frames where the shape changes and let Resolve interpolate between them. One continuous track won't hold a changing silhouette.
- Select the upper take on the Color page, add a Serial node and draw a Curve Power Window around the region you need to keep. For clones that stay apart, a loose boundary through unchanged background may be enough; crossings need a closer outline.
- Open the Tracker palette, set it to Window mode and track forward and backward from that frame, as long as your position moves but your outline stays fairly constant.
- When the outline changes, switch the Tracker palette from Clip to Frame mode before you move any window points. Add a keyframe where the fit is still good, go to the changed pose and adjust the shape. Frame mode keyframes and interpolates those edits; Clip mode changes the shape across the whole clip.
- Once the shape holds for the full clip, right-click an empty area of the node graph, choose Add Alpha Output and connect the node's blue key output to the blue Alpha Output connector.
Watch the tracked window and the finished composite through the whole shot. Blackmagic's Frame-mode instructions explain the difference between a clip-wide correction and an animated shape. For complex limbs, repeated occlusions or several holdouts, the Fusion rotoscoping workflow is a better next step than forcing one window to describe everything.
Making Two Resolve Clones Interact or Cross Paths
A fixed split works as long as what you need from each take stays inside its retained region. Two clones looking at each other is fine. If a hand, prop or shadow reaches the boundary, my first move is to slide the seam through unchanged background. If that doesn't work, animate the boundary or isolate the crossing element, and remember that a subject mask alone won't keep every cast shadow.
Use the clap, spoken cue or hand signal from the shoot to find the exact frame where the interaction has to land. Trim both clips to that reference before you mask anything; matching raw clip lengths won't sync two performances.
For a Fusion version, select the aligned, overlapping video takes on the Edit timeline, right-click and choose New Fusion Clip. In Fusion, check which take each MediaIn holds by viewing it, not by guessing from the node number. Connect the base take to the Merge's orange Background input and the upper take to its green Foreground input, then send the Merge to MediaOut. The manual’s Merge input reference separates these from the blue Effect Mask input.
Connect a Polygon or B-Spline mask to the Merge's blue Effect Mask input to limit where the upper take appears. A loose garbage mask can throw away unwanted background as long as its edge stays clear of both performances. It's not a detailed subject matte, and it won't save a body that crosses that edge. Animate the shape when you need to, and keep the base take visible outside it.
When the front-to-back order changes, use a separate holdout shape or another masked branch for the crossing hand, body or prop. The later foreground Merge sits on top wherever its alpha and mask allow it. Check the first overlap frame, the tightest crossing and the last overlap frame, then play the whole interval; one correct still frame proves very little.
Moving-Camera Clone Effect in Fusion
A moving-camera clone isn't the fixed-crop method with stabilization bolted on at the end. Both takes need repeatable camera movement, or enough shared background detail to produce compatible tracks. If the camera path and parallax differ a lot between takes, no node arrangement will make the perspectives identical. That's where I'd plan a controlled reshoot, which is often faster and cleaner.
In Fusion, track stable background detail in each take, not the performer, and use compatible reference frames. One tracked pattern supports position; the Resolve 21.1 manual needs at least two for Steady Angle and Steady Size. Adding more patterns won't make incompatible perspectives match.
Steady each take, then register the two backgrounds at the reference frame before you mask and merge. Stabilizing each take on its own removes motion relative to that take; it doesn't align one take to the other. Compare fixed edges across the whole shot, not only the reference frame.
For translation-only motion, connect a pre-Merge Transform Center on each take to that take's Tracker Steady Position. After the Merge, connect one post-Merge Transform Center to the base take's Unsteady Position to bring back the camera move you chose.
Rotation and scale also need the paired Steady/Unsteady Angle and Size connections, with the matching pivot and axis setup. The Tracker output reference explains those published controls. It depends a lot on the shot, so use the Fusion tracking guide for the tracker and reference-frame setup; position-only wiring isn't the full answer. Look for blank edges and parallax throughout the composite.
At a hand-off, a body turn or a crossing, add mask points or keyframes where the outline and occlusion order change. Resolve can interpolate keyed shapes, but it can't decide which clone belongs in front. The Fusion tutorial for beginners explains Merge order.
Fixing Resolve Clone Effect Edges, Shadows and Sync
Edge flicker can come from a drifting track, an occlusion, changing motion blur, noise or weak subject contrast. On the Color page, use Highlight (Shift+H with the default shortcuts) to inspect the selection, then switch it off to judge the composite. In Fusion, view the mask or alpha channel itself. Color-page Highlight isn't a Fusion matte-view command.
If you shot the takes against a green or blue screen, keying is another way to get a subject matte. You still have to match timing, lighting and foreground order.
For chroma-key footage, refine the alpha before you chase edge spill; the Delta Keyer guide covers that separate workflow. An ordinary room background is no reason to add a chroma keyer.
Keep the lights where they are and shoot the takes close together if the daylight is changing. A shadow may need its own retained region or matte; cut tightly around the body and you can lose the contact shadow, which makes the clone look like it's floating. Avoid feathering across a second shadow or a moving object, because that creates a see-through double image.
A clean background plate isn't mandatory for a locked split, because one performance take can stay as the base. An empty take helps when neither performance shows the background you need, or when you have to patch out a stray prop or shadow. Match its camera, lighting and timing where background motion matters. It gives you background pixels, not a missing hand, a correct contact shadow or an automatic answer to occlusion.
For three or more separated performances, repeat the same upper-track crop and give each take its own video track. The duplicate and stack clips guide covers the timeline mechanics; you still need to check masking and performance sync for every clone.
Clone Effect FAQ
Do you need DaVinci Resolve Studio to clone yourself?
No. The split-screen crop method and manual Power Window masking both work in the free version. Magic Mask speeds up masking when your clones cross paths or move through a changing outline, but it's Studio-only.
What's the easiest way to clone yourself without masking in DaVinci Resolve?
Stack two takes on separate tracks and crop the upper clip at a fixed line with Inspector > Video > Cropping. Keep both performances and any shadows you need inside their retained regions. If something crosses the boundary, move the seam if you can, or use an animated boundary or a subject matte with the shadow and occlusion work that goes with it.
Why do my DaVinci Resolve clone effect edges flicker?
A drifting track, an occlusion, motion blur, noise or low subject contrast can all make an edge flicker. On the Color page, inspect the selection with Highlight (Shift+H with default shortcuts). In Fusion, look at the mask or alpha channel. Then watch the actual composite in motion before you change any edge settings.
How many clones can you stack in DaVinci Resolve?
There's no two-clone rule. The practical ceiling depends on your system, source codec, timeline resolution and compositing method. Cropped split-screen layers are fairly light; several live Magic Masks, tracked mattes and high-resolution Fusion branches need far more GPU memory and processing time.
Can you do the DaVinci Resolve clone effect without a green screen?
Yes. A green or blue screen is optional. A locked-camera crop needs no subject key at all, and Power Windows and Magic Mask can isolate a subject against an ordinary background. Use Delta Keyer only when the footage was actually shot for chroma keying.
Can you clone yourself with a moving camera in DaVinci Resolve?
Yes, if the takes have compatible camera motion and perspective. Steady the takes, register their backgrounds, composite, then bring back the camera move you chose. Translation uses Steady/Unsteady Position; rotation and scale need their paired controls and pivot setup. Very different handheld parallax may mean a reshoot.
