Tier 1 AI bundle: Lip-Sync · De-Um · AI Silence Removal

AetherCut v1.7.25 shipped on Mar 2026 with 3 updates to the private, browser-based video editor. Everything here is already included in the latest version. AetherCut edits on your own device, so your footage never has to be uploaded to a server.

What's new in v1.7.25

• AI Lip-Sync — re-renders the speaker's mouth to match a new audio track. Perfect for dubbed videos so lips match the new language (fal.ai sync-1.7.1)
• AI Voice Cleanup (De-Um) — Whisper word-timestamps detect 'um', 'uh', stutters → surgical micro-cuts remove them without trimming real speech
• AI Silence Removal — transcript-aware (not energy-based) silence cut. Never mistakes a quiet 'yeah' or breath for dead air, unlike the legacy silence trimmer
