+Local renders on FFmpeg 4 no longer turn a finished mix down by several dB when they match its length to the video. Motion blur can now choose when its shutter opens.
+
+## Features
+
+- **Core:** `data-motion-blur-phase` sets when the motion-blur shutter opens in each frame ([aace91b](https://github.com/heygen-com/hyperframes/commit/aace91b5ec0d937772f66ab06e63c5755e579646), [#6983](https://github.com/heygen-com/hyperframes/pull/6983)).
+
+## Fixes
+
+- **Render:** On FFmpeg 4, a mix already under the peak limit is no longer turned down by several dB when its length is matched to the video. Two near-identical mixes no longer land about 4 LU apart ([f6ae9bf](https://github.com/heygen-com/hyperframes/commit/f6ae9bfb43a4e4bee0d132a5ac2a0b1ce4bf383f), [#7199](https://github.com/heygen-com/hyperframes/pull/7199)).
