AI Summary
This release enables bundling of local fonts and images up to 2 MiB into the HTML output for better portability. It resolves several rendering issues including missing clips, video layout shifts, and provides a fallback mechanism when disk space is low.
Key Highlights
- Embeds fonts and images up to 2 MiB into the bundled HTML to improve portability.
- Implements low disk space recovery by using a streaming fallback when saving frames.
- Fixes video layout shifts caused by inactive nested videos during rendering.
- Corrects clip visibility to ensure root-level clips appear at their scheduled start times.
- Enhances AAC audio peak correction to prevent re-encoding issues.
Full Release Notes
# HyperFrames v0.8.37 Released on 2026-09-13. Bundled HTML now embeds supported fonts and images up to 2 MiB each, so they remain available without the project folder. This release also fixes missing clips, shifting video layouts, render recovery on low disk space, and AAC audio peak correction. ## Fixes - **Bundling:** Embed supported local fonts and raster images up to 2 MiB each in bundled HTML. Larger assets warn and remain external, as do audio and video ([cd975d8c2](https://github.com/heygen-com/hyperframes/commit/cd975d8c2805acc78542a68433271f771352de23), [#3590](https://github.com/heygen-com/hyperframes/pull/3590)). - **Rendering:** When capture verification fails, use the available streaming fallback if saving frames to disk would exceed available storage ([4c26ffe8c](https://github.com/heygen-com/hyperframes/commit/4c26ffe8ce910ae1b3a41479192f613a6a4bd75b), [#3703](https://github.com/heygen-com/hyperframes/pull/3703)). - **Video layout:** Keep inactive nested videos out of the layout so neighboring videos do not shift during rendering ([fdf9ffac9](https://github.com/heygen-com/hyperframes/commit/fdf9ffac953d9d18329907d6956faa58c73ad489), [#3639](https://github.com/heygen-com/hyperframes/pull/3639)). - **Clip visibility:** Show later root-level clips when their start time arrives, even if the runtime previously hid them ([1acc65dbf](https://github.com/heygen-com/hyperframes/commit/1acc65dbf813d5750c241c7e6e15b48329271ffb), [#3893](https://github.com/heygen-com/hyperframes/pull/3893)). - **Audio:** Leave extra headroom when correcting AAC peaks so re-encoding is less likely to push them back above the delivery limit. Failed corrections now report measurements ([58707afaa](https://github.com/heygen-com/hyperframes/commit/58707afaa04371b1d2cd7b5ff9154804add7f652), [#3693](https://github.com/heygen-com/hyperframes/pull/3693)). ## Docs & Examples - Fix links to examples, transitions, and shared guidance in the video creation skills ([4aa6e17b7](https://github.com/heygen-com/hyperframes/commit/4aa6e17b762e9478d2bfd35e1ac6cc6f011a5d0c), [#3920](https://github.com/heygen-com/hyperframes/pull/3920)). ## Full changelog https://github.com/heygen-com/hyperframes/compare/v0.8.36...v0.8.37
