Adobe After Effects Moves Rotoscoping Toward Object Selection

The June Creative Cloud update replaces the old brush-first Roto Brush workflow with Object Matte, a set of AI-assisted selection tools for isolating subjects before compositing.

Adobe’s June Creative Cloud update gives After Effects users a new way to do one of post-production’s least romantic jobs: cutting a moving subject away from its background.

The new Object Matte system replaces the brush-only Roto Brush workflow with four AI-assisted tools: Object Selection, Quick Selection, Selection Brush and Refine Edge. In practical terms, the promise is less frame-by-frame nudging before a compositor can isolate an actor, prop, vehicle or other moving object for effects work.

Rotoscoping is the process of creating a matte, or cut-out, around something in footage so it can be adjusted separately from the rest of the image. It is essential in compositing, but it can also be slow, repetitive and extremely unforgiving when hair, motion blur, smoke, shadows or handheld camera movement get involved. The computer is being asked to understand an object over time, not just draw a neat outline on one still frame. Naturally, it has opinions.

Adobe says Object Matte can select a subject, propagate the matte across frames and freeze the result for compositing. Quick Selection is effectively the reworked Roto Brush, while Selection Brush and Refine Edge are there for the less magical part of the job: fixing and softening edges where the automatic selection needs help.

That makes this a useful update rather than a clean removal of roto labour. Post teams should read it as another step toward assisted isolation inside mainstream tools, not as proof that difficult roto shots have suddenly become one-click work. Clean product shots and well-separated subjects are one thing. Hair against a busy background, low-light footage and fast motion remain where the invoice earns its keep.

The more interesting workflow question is where this leaves junior roto and cleanup tasks. If Object Matte holds up on ordinary production footage, some shots that would previously have gone out to a dedicated roto pass may stay closer to the editor, motion designer or compositor. That could save handoffs on simpler work, but it also moves more judgement into the person using the tool: when to trust the matte, when to fix it, and when to stop pretending the machine has understood the shot.

Adobe has also added Creative Cloud updates outside After Effects, including Photoshop reflection removal and Lightroom Assisted Culling. Those are useful in their own lanes, but the After Effects change is the one most directly tied to post and VFX workflows.

The sensible test is not whether Object Matte looks good in a demo. It is whether it survives the miserable footage professionals actually receive: soft edges, bad lighting, compression, camera shake and a producer asking whether the shot can be ready by lunch.
