OpenShot 4.0 lands with colour grading, local AI masks and a recording dock

Colour grading and a native Qt timeline change the editing canvas

The headline change in OpenShot 4.0 is a colour grading toolset that the maintainers describe as professional, paired with what they call a cleaner native timeline. Coverage across multiple Linux-focused outlets on August 31, 2026 frames both as the centrepiece of the release: a grading workflow that had previously required an external tool is now inside the editor, and the timeline surface itself has been rebuilt rather than patched. For a creator who has been bouncing between OpenShot and a dedicated colour app, that removes a round-trip and an export step before the final render.

Recording dock, Wayland capture and one clip per source

The second notable shift is built-in capture. OpenShot 4.0 ships a Recording View with an audio recording dock that pulls in screen, webcam, microphone and system audio as separate media files. Each captured source becomes its own timeline clip, so a recording session lands directly on the cut surface without a separate import step. Screen and webcam recording are now supported on Linux under Wayland, closing a gap that had blocked headless and hybrid-GPU Linux setups from recording inside the editor. Creators who previously routed capture through a separate utility can now keep the entire capture-to-cut path inside one project.

Local AI masks and ten new effects push AI work onto the desktop

0 introduces what the release blog calls local object masks, generated on the user's own machine rather than in a cloud service. The same release adds ten new effects, which Linux press coverage groups as a new set of AI effects. For practitioners, the combination matters because masking work that previously required an online tool — with the upload step that implies — stays local.

That fits the broader pattern of browser-side and on-device video utilities reducing friction around upload, compression and re-encoding, as covered in Generative video, AI chaptering and on-prem media search reshape creator and post workflows and AI video tools push deeper into post-production as browser-side compressors and timeline automation arrive.

Where browser-side utilities still earn their keep

0 reduces the need to leave the editor for grading, masking and capture, but it does not change the format-conversion and resizing work that sits on either side of the editor. Creators trimming a clip to fit a platform's duration cap, re-encoding for upload, or pulling audio from a captured screen recording still reach for browser-side tools. Practical fits include Video Trimmer for length limits, Video Resizer for aspect ratio changes, Video to Audio Converter for extracting audio from a screen capture, and the beginner-oriented walkthrough in Video Compressor for Beginners: A First Local Run.

For platform-specific trimming, Trim a Video for WhatsApp in Your Browser Locally, Trim a Video for Instagram Story Without Uploading and How to Trim a Video Without VLC cover the common destination limits a creator hits after editing.

What to check after upgrading

0 and confirm three things on a real project: that colour grading reads correctly on a clip previously graded in an external app, that Wayland screen and webcam capture actually records on the creator's Linux setup, and that local object masks run at an acceptable frame rate on the available hardware. A second pass worth running is the new effects set — ten effects is a wide range, and performance will vary by GPU. Creators who cut for a living should also retest export presets, since the timeline rebuild is the kind of change that can quietly shift render behaviour.

The release does not name a pending follow-up version or a hard deadline in any of the coverage, so further changes will arrive on the maintainers' own cadence rather than on a stated date.
