AeonCut
AeonCut is a video editing utility that cuts audio silence and breaths for DaVinci Resolve.
AeonCut is an audio silence and breath cutter designed for DaVinci Resolve 21, 20, and 19. It runs as a native application powered by Rust and egui with a GPU-accelerated interface and voice activity detection. The software operates entirely locally to ensure privacy without uploading audio or video to external servers. It features non-destructive editing that preserves media references so edge handles can be trimmed or adjusted on the timeline. Users can choose between multiple cutting modes including automatic new timeline creation, appending to an active timeline, or adding clip markers for manual review.
