Building real-time video and audio features usually means making a painful compromise: either you ship basic, unpolished media feeds, or you burn a massive hole in your infrastructure budget processing AI video effects on expensive GPU servers. Effects SDK completely rewrites this math by shifting the entire processing payload—background blur, smart framing, low-light correction, and AI noise suppression—directly to the client side.
It is fantastic because the underlying engineering leverages modern web and native runtimes (like WebGPU, WASM SIMD, CoreML, and WinML) to run heavy machine learning models smoothly on consumer hardware. For developers, this provides the holy grail of real-time media architecture: exceptionally low processing latency, zero server compute scaling costs, and absolute ironclad privacy because sensitive camera and microphone data never leave the user's machine. The API wrapper is beautifully straightforward, reducing complex multi-threaded pipelines down to a few lines of configuration.
Client-side and on-device is exactly why I'd reach for this over a server-side pipeline — for a privacy-sensitive app it means the video frames never leave the browser. On the plumbing: what's the added bundle weight, and does the segmentation model require WebGPU or is there a WASM/CPU fallback for users on older machines? Trying to gauge how gracefully background blur degrades on a low-end laptop before wiring it into an existing WebRTC stack.
@hi_i_am_mimo Thanks for the question! The SDK automatically checks whether WebGPU is supported and working correctly. If it is unavailable or any issues are detected, it falls back to WASM SIMD, and then to standard WASM when needed.
Developers also have explicit control over the execution backend, so you can choose the most appropriate option for your target devices and performance requirements.
The tiered fallback with an explicit backend override is exactly what I'd want for shipping to unknown devices. One practical thing for debugging in the field: is there a runtime signal I can read to know which backend actually ran for a given session, so I can correlate dropped frames with the WASM path rather than guessing? And roughly what performance delta do you see between WebGPU and WASM SIMD on a mid-range laptop?
The client-side approach makes the integration story especially interesting because performance becomes part of the product experience, not just an infrastructure detail. Beyond the quality presets and per-effect controls, do you expose any runtime signal that helps an app decide when to reduce effect complexity or disable a feature on weaker devices? That kind of graceful degradation seems important for products with a wide range of hardware.
@wesc Absolutely—you’re right, this is important.
The SDK exposes a range of runtime metrics, including FPS, segmentation inference time, and frame rendering time. These signals can be used to detect performance degradation and dynamically switch to a lighter preset, reduce effect complexity, or disable an effect when necessary.
We don’t directly manage broader system signals such as thermal state, CPU pressure, or overall device load, since those are usually best handled at the application level, where developers can apply their own product and business logic.
We also had an interesting discussion about this in the forum thread—check it out:

the GPU-for-segmentation / CPU-for-audio split for mobile is a smart way to avoid contention, good answer. one thing I'm curious about on the "nothing leaves the device" claim - for enterprise customers who need to actually prove that to their own compliance/security teams (not just take the marketing copy), do you provide anything concrete like a network traffic audit, an offline-mode flag they can verify themselves, or a SOC2-style attestation? that's usually the sticking point once a claim like that has to survive a security review.
@galdayan Absolutely. We’ve worked with larger customers that required a full security and compliance review before integrating the SDK.
For the mobile and desktop versions, we support a fully offline mode that customers can verify in their own environment.
For the web version, there is one required control component: the session server. Full offline operation is more complex on the web than in native applications, but we offer an on-premises deployment option where the session server runs entirely within the customer’s infrastructure. No external connection is required, so it can also operate inside an isolated local network without internet access.
The session server does not process any video or audio. It only handles the key exchange required for the Web SDK to decode the models locally as part of the client-side processing flow.
qq. can devs adjust the threshold levels for features like background blur intensity or noise suppression aggressiveness via the API? by the way congrats👏 for launching @maxim_troshin
@priya_kushwaha1 Thank you! 👏 Yes, developers can adjust effect parameters through the API. Background blur intensity is configurable, noise suppression supports different sample rates and suppression strength levels, allowing developers to balance audio quality, performance, and processing aggressiveness.
@maxim_troshin Awesome 🙌 API-level control over these parameters is a huge plus for developers, thanks for confirming
How does performance hold up on lower-end mobile devices when running multiple effects like background blur and noise suppression at the same time?
@eymenjez0 Thanks for the question! In our mobile SDKs, background segmentation runs on the GPU, while noise suppression runs on the CPU in a dedicated high-priority audio thread.
This separation helps distribute the workload more efficiently and makes performance much more stable, even when both features are running at the same
Real-time is the word that makes or breaks this for me. I cut a lot of screen-recorded product demos, and the effects I care about (blur, denoise, auto-captions) are cheap to run after the fact but brutal live. What's the latency budget on the audio side before it drifts out of sync with the video? That's usually where "real-time" quietly becomes "near-time."
@chielephant Great question! We don’t currently provide auto-captions in the Audio SDK, although it’s something we’re considering.
On the audio side, the typical added latency is around 100–150 ms. This comes mainly from collecting the audio chunk required by the model and using a small jitter buffer to keep the output stable.
For video, our target is typically 24–30 FPS, which matches the frame rate used by most video conferencing applications.
