Building a video editor SDK for React Native, powered by Nitro ⚡️
Trim, layer, add effects, and export with native performance — using your own UI.
Here’s a first look 🎬
#ReactNative #nitro
Today's Video Editor SDK update:
• iOS: animated overlays (enter/exit, fades) in preview and export
• Android: photo clips rebuild 9× faster in preview on a Galaxy A13 (1.39 s → 0.15 s)
• Found a Media3 bug that drops frames at open-GOP clip ends, sent a fix upstream
• editor open → first frame: iPhone 13 313 → 226 ms, iPhone 16 Pro 256 → 184 ms
• play after seek on iPhone 13: ~0.5 s → ~0.2 s
• blur-fill backgrounds: planned in the shared C++ core, GPU passes next

video-editor SDK updates:
• Frame-exact scrubbing
• iOS color grading, curves & 3D LUTs in preview + export
• Paused preview edits on iPhone 13: 44 → 27 ms median
• Audio time-stretching: 46–62% less CPU time in Galaxy A13 / Pixel 8a benchmarks

Great news 🔥🔥🔥
Announcing Apex: agentic coding model for mobile and web, specialized in React.
We built Apex from a single idea: can an open-weight model deliver frontier-level performance at lower cost?
Yes. Apex is SOTA in React Native and Next.js.

I just built one of the fastest mobile media-encryption demos in React Native.
A 2.21 MB photo, encrypted and decrypted entirely on-device with OpenMLS:
38.3 MB/s encrypt
46.5 MB/s decrypt
Rust + Nitro Modules + zero-copy JSI.
Full native performance, exposed through React Native. – at Berlin, Germany
