# HyperFrames v0.8.194

By Steven Van · 2026-10-25

Studio's undo and restore now keep deleted or replaced media, and motion blur no longer blacks out videos in sub-compositions.

Undo and restore in Studio no longer lose files. When a history step deletes or replaces media, [HyperFrames](<https://creatorstoolbox.com/resources/hyperframes>) now keeps that media, so stepping back restores it. The [v0.8.194 release](<https://github.com/heygen-com/hyperframes/commit/0289d96ac78ab827e6ae1056d2e60e3716d21e9d>) also stops motion blur from blacking out videos inside sub-compositions. Around 25 smaller fixes cover the CLI, core and lint.

## Feature

- **Studio:** the blur panel now turns on events with blur.

## Notable fixes

- **Studio Server:** undo and restore keep the media they delete or replace.

- **Parsers:** each keyframe array keeps its own timing.

- **Core:** scene shots keep their shell after leading comments.

- **Engine:** concat resolves relative paths without dropping clips.

- **Player:** Next stays available for the final slide's reveals.

- **Sdk:** added elements are kept when saved overrides are reopened.

- **CLI:** filtered keyframes now produce valid JSON, and explicit preview port discovery is scoped.

- **Lint:** GLSL script blocks no longer raise JavaScript syntax errors, and a final font-family descriptor without a semicolon is accepted.

- **Producer:** unavailable frame checks are now reported in debug logs.

The release notes list the remaining fixes by pull request number.
