# HyperFrames v0.8.199

By Steven Van · 2026-10-25

HDR renders extract frames in windows to cap scratch disk, and the docs now spell out how volume lanes multiply data-volume.

Long HDR videos now render without filling the disk, and parallel capture stays on after one failed frame check. [HyperFrames](<https://creatorstoolbox.com/resources/hyperframes>) v0.8.199 also adds a lint warning for scene styles placed outside the scene's template. The [linked commit](<https://github.com/heygen-com/hyperframes/commit/9b80c2d01efa48ae48cd702129def7ec4eb6faf4>) is a docs change to the media-use skill.

## Features

- **Lint:** warns when a scene's styles sit outside its template.

## Fixes

- **Producer:** HDR video frames are extracted a window at a time, which bounds scratch disk use on long videos.

- **Producer:** --workers N is now a ceiling, and drawElement renders keep their single worker.

- **CLI:** a failed frame check no longer switches parallel capture off for good.

- **CLI:** a long video copy reports progress, resumes in 15 s pieces and stops only when stalled.

- **Studio:** scrubbing never auditions a track the music row did not name.

- **Core:** the decoded-audio cache keys a clip the same way everywhere.

## Performance

Mounting a scene no longer restyles it to look for raster hints.

## Docs: volume lanes and data-volume

The linked commit updates the media-use skill's mixing reference. A volume lane multiplies data-volume in both preview and render, so the level should be written in only one of them. For example, data-volume="0.5" under a lane at 0.5 plays at 0.25.

The release also includes internal changes: the CLI now checks the browser that ran a hanging script, and that every browser it started is gone. The engine counts what the mixer read from a cloud file, not what the server buffered.
