I've been wrestling with Descript's green screen keyer for the last three projects, and the consistent failure point is the halo effect. It's not the subtle fringe you can sometimes fix with spill suppression; it's a persistent, semi-transparent ghost of the background color clinging to edges, especially around hair and fine details. It makes the subject look like they're glowing with a sickly green aura, which is, to put it mildly, unacceptable for a final deliverable.
I've come to the conclusion that the default "Key" slider and "Clean Up" settings are essentially placebo buttons for anything but a perfectly lit, brand-new chroma key backdrop. My typical workflow involves shot-on-location interviews where the green screen has a wrinkle or two and the lighting is good, but not studio-perfect.
Here's what I've tried, with systematically disappointing results:
* **Adjusting the "Key" threshold:** This either cuts into the subject (making hair look like a helmet) or leaves the full halo intact. There's no sweet spot.
* **The "Clean Up" sliders (Clean 1 & Clean 2):** These seem to apply a blur or erosion that just smears the halo rather than removing it. It degrades the edge detail without solving the core problem.
* **Manual "Add/Remove" brushes:** A tedious workaround for a problem that shouldn't exist at this baseline. It's not scalable for a 30-minute interview.
* **Pre-processing the clip in a dedicated editor (DaVinci Resolve):** This works, but it completely defeats the purpose of an all-in-one tool like Descript. If I'm round-tripping to a proper color grading suite, the keying feature here is moot.
The core question is this: is there a hidden workflow or a specific order of operations that actually produces a clean key? I'm looking for concrete, tested settings.
Specifically:
* What are your exact slider values for a **less-than-perfect** green screen?
* Is there a crucial step before hitting the "Key" button, like a specific color correction on the clip?
* Does the quality of the original video export (codec, bitrate) dramatically impact the keyer's ability to sample colors accurately?
I'm not interested in "it works great for me!" anecdotes from people using a $2000 panel light setup. I need the practical, gritty settings for the real world where backgrounds are 85% clean and budgets don't allow for re-shoots. If the answer is "the feature is fundamentally underpowered," I'd rather just know that, so I can adjust my toolkit and stop wasting time.

I'm an infosec lead for a 300-person fintech, and my team runs vulnerability scanning and pentesting for our entire production stack, which includes a ton of internal training and marketing video content.
You're hitting the ceiling of an all-in-one tool. Descript's keyer is built for speed and simplicity, not for salvaging imperfect source footage. Here's how it actually stacks up against purpose-built options for a professional workflow:
* **Target Audience & Fit:** Descript is built for creators and small teams doing straightforward edits. If your backdrop has wrinkles and your lighting is "good, not perfect," you're already outside its design envelope. A tool like DaVinci Resolve's Studio (a $295 one-time purchase) or even a SaaS like Riverside.fm's AI-based removal is built with these variables in mind.
* **Real Pricing & True Cost:** Descript runs $12-24/user/month. The hidden cost is the time you're burning wrestling with it. A standalone keying plugin like Red Giant's Keying Suite (approx $199/year) is cheaper than a year of Descript if keying is your primary bottleneck.
* **Where It Breaks:** It lacks advanced controls for spill suppression and edge refinement. You mentioned the "Clean Up" sliders just smear the problem. That's because they're global adjustments. Professional keyers let you isolate and correct color spill (that sickly green aura) separately from the matte edges, which is what you need.
* **Integration & Workflow:** Descript wants you to stay in Descript. Getting a clean key often requires a round-trip to another editor. At my last shop, we settled on a protocol: anything needing a complex key goes straight from the camera to DaVinci for that step, then the cleaned-up footage is edited elsewhere. The added step saved hours.
My pick is DaVinci Resolve Studio. It's the pragmatic choice for your specific case of location interviews with minor backdrop issues. The qualifier is your hardware; its Fusion page needs a decent GPU. If you're on an older machine or need a pure web solution, tell us your budget and your computer specs.
