OpenShot 4.0 Release Brings Local AI to Free Video Editing
OpenShot 4.0 shipped yesterday, and it's the biggest upgrade in the project's 18-year history — 428 points and 99 comments on Hacker News within a day. The headline is one AI features like this usually aren't: subject-isolation masks that run entirely on your machine. No cloud, no account, no subscription.
What shipped in OpenShot 4.0
Three workstreams landed at once:
- Recording View — capture mic, screen, webcam, and system audio straight into a project, each source kept separate and editable.
- Color View — color wheels, editable curves, industry-standard
.cubeLUTs, and live pro scopes: Luma Waveform, Histogram, RGB Parade, Vectorscope with a skin-tone reference line. All keyframable. - Local AI masks — select and follow subjects using free downloadable models that run on your computer. No cloud service, no subscription.
Plus 10 new effects (audio-reactive graphics, beat-synced flashes, cinematic film looks), a cleaner native timeline, dramatically faster Blur, and expanded Qt 6 support that lays groundwork for Android and newer Linux distros.
Why local AI masks matter
Video is the most sensitive data most people own — faces, homes, screens. Every mainstream editor pushes AI through a cloud API, which means your footage becomes someone else's training set. OpenShot inverts that: the mask model downloads once, then inference happens on-device. Same capability, zero surveillance tax.
That's the pattern Dispatch keeps flagging — open weights won, and now the capability is cheap enough that a free, volunteer-run editor ships pro color grading and on-device segmentation as a baseline. The bar for charging for this stuff just moved.
The verdict
Not the flashiest AI release this week, but the most democratic. If you edit video and care where your footage goes, 4.0 is the reason to check OpenShot again. HN's 428 points in a day says the appetite is real.
