Polley Auto Smash Cut

Automatically remove silence from video or audio — with a review step. Analyze first, see every proposed cut on a timeline, adjust or restore anything you want to keep, preview the tightened result, then export. Your originals are never modified.

Review before you commit

Waveform timeline shows kept regions and red removed-silence blocks.
Click a block to jump there; drag its edges to fine-tune the cut.
Restore any region you want to keep, remove it again if you change your mind.
Preview tightened playback skips the removals so you hear the final pacing before exporting.

Batch processing, honest progress

Add files or a whole folder; video and audio mix freely in one batch.
Per-file state, overall progress, and cancel that actually stops FFmpeg and cleans up partial files.
Retry just the failed files without re-running everything.
Outputs land next to your sources, or in a folder you choose.

Presets & formats

Podcast, Talking Head, Gameplay, and Superchop presets; editing a value switches to Custom.
Video exports as .mp4.
Audio exports as .mp3, .wav, or .m4a.
Every output keeps the _smashcut naming, with collision-safe numbering when needed.

Local & private

All processing happens on your machine.
FFmpeg is bundled inside the app — nothing else to install.
No telemetry. Update checks only happen when you click Check for updates.
Keep-before and keep-after padding protects word endings — no clipped consonants.
