# HyperFrames v0.8.206

By Steven Van · 2026-10-26

HyperFrames v0.8.206 trims Studio scrub overhead, removes a 45-second render setup wait, and fixes frame and PNG colour mismatches between preview and render.

Scrubbing a long film in Studio now costs less, and a composition with no timeline script no longer waits 45 seconds before it renders. [HyperFrames](<https://creatorstoolbox.com/resources/hyperframes>) v0.8.206 also makes preview and render agree on the video frame and on a PNG's colours, and HEIC photos now work in compositions. The [linked commit](<https://github.com/heygen-com/hyperframes/commit/121bf20e99da6c514d7ae0a0fe166c4a12ae7209>) covers the Studio scrubbing change.

## Cheaper scrubbing in Studio

While a scrub is running, the preview posts state messages, and each one could trigger a re-read of the preview for missing compositions. That re-read queries the whole document. It now runs at most every 500 ms. The commit adds a test showing that repeated state messages inside that window trigger a single re-read, and that another one runs once 500 ms have passed.

## Other changes in the release

- **Check:** the CLI's check command catches audio that the render would lose or play as silence.

- **PNG colours:** a PNG's colour tags no longer change its pixels in preview, check, snapshot or render.

- **Video frames:** a paused preview and the render show the same, correct frame. Snapshots keep the colours that render gives the same footage.

- **Setup wait:** a composition with no timeline-registering script no longer waits 45 s at setup.

- **HEIC:** HEIC images are converted to JPEG at compile time.

- **CLI:** a killed CLI no longer leaves its child processes running. The Windows console is hidden for the port lookup and clipboard. Play and present ports are now validated.

- **Compositions:** a composition behind a wrapper takes its host's start.

- **Engine:** a failing root composition script now has the element it looked up named in the error.
