Shotcut 26.9 Adds Audio Ducking and FFmpeg 9.0
↗
Shotcut 26.9 introduces automatic audio ducking, timeline track headers with volume controls, and adjustment clips for applying effects across multiple layers.
Engineers who edit video now can automate volume adjustments between speech and music without manual keyframes, reducing post-production time. The upgrade to FFmpeg 9.0 improves codec handling and resolves Linux kernel compatibility issues that previously broke project loading on newer kernels.

Automatic audio ducking lowers one track’s volume when another track becomes active.
Adjustment clips let filters affect all underlying video layers without extra panels.
FFmpeg 9.0 upgrade fixes HEVC encoding and improves cross-platform stability.
THE READ
What the cluster adds up to.
The release adds audio ducking directly into the timeline, letting editors automate volume automation for voiceovers and podcasts, which previously required manual keyframe work.
Adjustment clips consolidate multi-layer effects into a single filter instance, simplifying workflows for complex composites and reducing the need for repeated filter additions.
Upgrading to FFmpeg 9.0 resolves crashes and encoding bugs on Linux kernels 7.1+, restores correct path handling for non-ASCII filenames, and repairs HEVC hardware encoding, addressing long-standing stability concerns for developers on modern distributions.
