# HyperFrames v0.8.174

By Steven Van · 2026-10-19

The CLI's timeline delete now cuts only the chosen range, and Lambda renders assemble in seconds and scale to account concurrency limits.

Deleting a time range from a timeline clip in [HyperFrames](<https://creatorstoolbox.com/resources/hyperframes>) now removes only that range instead of the whole clip. The change is part of [v0.8.174](<https://github.com/heygen-com/hyperframes/commit/26d7dbca360b25b3ab48a0ee372fbbbc965de5cd>), which also speeds up cloud renders and adds a batch of fixes.

## Timeline delete

The CLI's timeline delete command with --start and --end now cuts just the range given. Before, it removed the whole clip.

## Cloud and Lambda renders

- Cloud renders download faster, and chunk output is assembled with a single faststart index.

- Lambda renders assemble in seconds.

- Distributed Lambda renders are sized from the account's concurrency limits, so they scale to those limits.

## Other fixes

- Color grading now applies to canvas compositions.

- Exports carry full colour tags with every encoder, for both SDR and HDR.

- A page-load timeout names the script or stylesheet the page was waiting on.

- Capture keeps other screenshots when Chrome refuses one.

- A render that no FFmpeg encoder can finish stops before capture, not after it.

- Back-to-back audio clips no longer count as overlapping in lint after float rounding.

- Preview inside a host app's agent run no longer outlives the run.

- init writes the project into a folder with a non-ASCII name on Windows.

- Generated artifacts are formatted without spawning bun from PATH.

## Capture and proxies

The linked docs commit adds a note to the CLI documentation: capture needs direct internet access. Since 0.8.164 it does not use HTTPS\_PROXY or HTTP\_PROXY, because its own proxy dials each checked public address itself. Where the only way out is a proxy, as in some sandboxes and corporate networks, every page fails with net::ERR\_TUNNEL\_CONNECTION\_FAILED, even though curl reaches the same site through that proxy.
