Object Matte vs Magic Mask vs Object Mask: AI masking compared (2026)
After Effects Object Matte, Premiere Pro Object Mask and DaVinci Resolve Magic Mask as of September 2026: workflow, refinement, cost and independent tests.
As of September 2026, After Effects Object Matte, Premiere Pro Object Mask and DaVinci Resolve Magic Mask all do the same basic job: you click or brush a subject, and the app tracks a mask through the shot. The practical differences are where they live, how much control you get over the edge, and what they cost. In the only published side-by-side we found, Larry Jordan’s April 2026 test, Resolve gave the best results but tracked slowest and had the hardest interface, and Premiere was the weakest of the NLE tools tested.
Below: what each tool is today, a comparison table, what that independent test actually found, the common failure modes and fixes, and when to move up to a dedicated roto tool or outsource. Features change often; every product fact here is dated and sourced, and we’ll update the post when vendors ship changes.
Which one should you use?
Mostly, the one in the app you’re already finishing in. Moving a shot to another app costs more time than any difference between these tools. With that caveat:
- You’re compositing in After Effects: use Object Matte. It’s the only one of the three built as a roto tool inside a compositor, with separate tools for selecting, brushing and refining edges.
- You’re cutting in Premiere Pro and need a quick isolation (a blur, a grade, a title behind someone): Object Mask. Check it on hair and fine edges before you rely on it.
- You’re grading in DaVinci Resolve Studio: Magic Mask. It did best in the one independent test, and Resolve 21’s Render in Place makes tracked masks cheaper to play back.
- The shot is a hero shot with hair, motion blur or overlapping subjects: treat any of these as a first pass, and read the section on when to step up.
What each tool is, as of September 2026
After Effects: Object Matte
Object Matte arrived in the After Effects public beta in February 2026, and “in AE 26.2, Roto Brush has been replaced by the Object Matte tool,” according to a member of Adobe’s After Effects engineering team on the Adobe Community forum. Adobe’s beta announcement describes four tools:
- Object Selection: one-click or marquee selection of a subject.
- Quick Selection: the classic Roto Brush, “reimagined”.
- Selection Brush: additive and subtractive strokes for fine-tuning.
- Refine Edge: for natural edges and fine detail such as hair.
The selection is then propagated through the shot. Adobe says Object Matte builds on the same AI technology as Premiere Pro’s Object Mask. If you depend on the old behavior, Adobe’s community manager said in August 2026 that older Roto Brush versions remain available through a version selector in the Effect Controls panel.
Premiere Pro: Object Mask
Object Mask is a tool in Premiere Pro’s toolbar. In Larry Jordan’s walkthrough, you drag the tool over the subject in the viewer, track the mask with the tracking arrows in Effect Controls, and apply it to the clip’s opacity. He notes that Premiere 26.2 added Smooth edges and Sharp edges options (“Smooth is better for hair”), and that Premiere, unlike Final Cut Pro, didn’t support negative feathering in that version.
In June 2026, Adobe said Object Mask “is now faster and more refined,” with “softer, more natural masks,” and that a mask can be regenerated after media goes offline and is relinked (Newsshooter, June 15, 2026). That update came after Larry Jordan’s test.
DaVinci Resolve 21: Magic Mask
Magic Mask lives on Resolve’s Color page. You click on the subject (Larry Jordan’s advice: “use as few clicks as possible and never more than five”), track in both directions, and refine with controls including Quality (“Better”), Radius, Blur Radius and Clean Black, plus paint tools for frame-by-frame fixes. To use the result as transparency you add an alpha output in the node graph.
Resolve 21, released on June 4, 2026 (CG Channel), added Render in Place, which, in Blackmagic’s words, lets you “cache a tracked mask as a traveling matte node” that links to your active node, “with significantly lighter processing.”
Magic Mask is a Studio feature. Blackmagic lists “magic mask for object isolation and tracking” among the AI tools you get by upgrading to DaVinci Resolve Studio, listed at $295 on its site; the free version doesn’t include it.
Side-by-side comparison
Everything in this table comes from vendor pages or Larry Jordan’s April 2026 test, as dated in the sources. Cells marked “Not verified” are details we couldn’t confirm from those sources.
| After Effects: Object Matte | Premiere Pro: Object Mask | DaVinci Resolve Studio: Magic Mask | |
|---|---|---|---|
| Version referenced | AE 26.2 and later (replaced Roto Brush) | 26.2 in the test; updated June 2026 | Resolve 21 (test used the 21 beta) |
| Where it lives | Compositor, per layer | NLE toolbar, per clip | Color page, per node |
| How you pick the subject | One click or marquee (Object Selection), or brush (Quick Selection) | Drag the tool over the subject | Click on the subject; few clicks |
| Edge refinement | Selection Brush (add/subtract), Refine Edge | Smooth / Sharp edges, feather (no negative feather in 26.2) | Quality, Radius, Blur Radius, Clean Black, paint tools |
| Playback / caching | Not verified | Mask can be regenerated after relink (June 2026) | Render in Place caches the tracked mask as a traveling matte node |
| Old tool still available | Older Roto Brush versions via a version selector | Not verified | Not verified |
| What you need | After Effects (Adobe subscription) | Premiere Pro (Adobe subscription) | DaVinci Resolve Studio; not in the free version |
| Independent test (Apr 2026) | Not included | Weakest of three NLEs tested | Best of three; tracking took about twice as long |
What the independent test found
Larry Jordan’s comparison, published April 29, 2026, tested the AI masks in Final Cut Pro 12.2 (Magnetic Mask), Premiere 26.2 (Object Mask) and the DaVinci Resolve 21 beta (Magic Mask) on a subject with solid edges, a woman with blowing hair, and an elephant turning. His findings:
- Final Cut Pro was the fastest and easiest, but left “a ‘halo’ around her hair that makes the mask look fake” and had trouble with strong shadows under the elephant’s trunk.
- Premiere “did an unacceptable job with the woman’s hair and lost portions of the elephant’s body.”
- Resolve “did the best job at tracking all the different parts of the elephant,” but took “about twice as long” to track as Final Cut Pro or Premiere.
His overall verdict: “Resolve (Studio version) did the best job but had the most inscrutable interface. Final Cut was the easiest – and fastest – to use… Premiere was the weakest of the three.”
Read it with its limits in mind. It’s one careful test on a small number of clips, not a benchmark. Resolve was a beta at the time, Adobe has updated Object Mask since, and After Effects Object Matte wasn’t included because the test compared editing apps. Jordan also notes that hair is “hard for any masking tool to isolate because it is small, translucent and moves a lot.” We haven’t published a test of our own; if you need to choose for client work, run the checks in Is AI rotoscoping good enough for client work? on your own footage.
Common failure modes and how to fix them
These tools fail in the same few ways. The fixes below are general technique; where a fix is specific to one app, it’s the control named in the sources above.
| Symptom | Why it usually happens | What to try |
|---|---|---|
| Halo or hard line around hair | Mask edge sits outside the real edge; hard, segmentation-style boundary | Refine Edge (AE), Smooth edges (Premiere), Quality “Better” and Radius (Resolve); choke slightly, then build the hair edge separately |
| Parts of the subject drop out | Low contrast, shadows, a limb moving independently | Add strokes or clicks on the problem frame and re-track; mask difficult parts separately and combine |
| Mask jumps to another object | Similar color or texture nearby; occlusion | Subtract strokes on that frame; add a simple garbage matte to exclude the area; track in shorter sections |
| Edges chatter from frame to frame | Each frame’s edge decided slightly differently | Slight matte blur or choke; hand-roto the edge on hero frames |
| Hard edge on a motion-blurred subject | Mask doesn’t reproduce the blur in the plate | Blur the matte in the direction of motion, or roto the fast frames by hand |
| Slow playback or tracking | The mask is recalculated as you work | Render in Place (Resolve 21); pre-render the matte; work on only the frame range you need |
In Adobe’s beta thread for Object Matte, some users also reported slow processing on high-resolution footage and propagated edges that looked lower resolution than the first selection. Those were beta reports; check whether they apply to your version and footage before planning around them.
When the matte leaves the app, keep it at plate resolution and in a format that carries alpha properly, and know whether it’s straight or premultiplied. We cover that in Alpha channels, ProRes 4444 and EXR.
When to step up to a dedicated roto tool or outsource
Built-in AI masks are good for isolation, grading and quick comps. Step up when the shot needs edges that hold at full resolution, editable shapes, or many overlapping subjects:
- Mocha Pro (Boris FX), built around planar tracking. Version 2026.5 (June 2026) updated its Object Brush, Matte Assist ML and Matte Refine ML tools for “more accurate edges to the AI-generated mattes,” added Point Track ML, and can render layer mattes as multi-layer EXR files (CG Channel).
- Silhouette (Boris FX), a dedicated roto and paint application that runs standalone or as a plugin in After Effects, Premiere Pro, Nuke, Fusion, Resolve and Flame. Its ML tools include Mask ML, Matte Assist ML, Matte Refine ML (“create natural edges from hard mattes”) and Optical Flow ML, which drives roto splines (Boris FX).
- SmartRoto for Nuke (Foundry, July 2026), which propagates artist-drawn splines through a shot rather than generating a pixel mask, and runs locally with about 8 GB of VRAM, per fxguide.
Outsourcing to a roto and paint vendor still makes sense when the shot count is high, the edges are the shot (hair in a beauty spot, a hero product), or the client expects roto shapes as part of the deliverable. If you’re new to what that work involves, start with What is rotoscoping?
nolanlabs works alongside all three apps. Every nolanlabs job hands back a matte you keep refining in whichever of these tools you use; details are under what you get back, and you can bring your hardest shot to a demo.
The practical takeaway: use the mask in the app you’re already in, test it on your hardest shot before you bid, and keep a dedicated tool or a roto artist for the shots where the edge is what the client is paying for.
Questions
- Is Roto Brush gone from After Effects?
- Not entirely. In After Effects 26.2, Roto Brush was replaced by Object Matte, according to Adobe's After Effects team on the Adobe Community forum. Adobe describes the classic Roto Brush as reimagined as Object Matte's Quick Selection tool, and says older Roto Brush versions can still be chosen with a version selector in the Effect Controls panel.
- Is Magic Mask available in the free version of DaVinci Resolve?
- No. As of September 2026, Blackmagic Design lists Magic Mask among the AI tools in DaVinci Resolve Studio, the paid version, listed at $295 on Blackmagic's site. The free version of DaVinci Resolve 21 doesn't include it.
- Which is best for hair: Object Matte, Magic Mask or Object Mask?
- There's no published head-to-head that includes all three on hair. In Larry Jordan's April 2026 test of the NLE tools, Resolve's Magic Mask did best overall and Premiere 26.2's Object Mask did poorly on a woman's blowing hair; After Effects Object Matte wasn't part of that test. Test on your own hair shots, because results vary a lot with background and motion.
