01Phase 01

1. Acoustic RMS & Transcript Scan

Scans raw video or audio tracks for quiet speech intervals and aligns subtitle tokens to identify hesitation filler words simultaneously.

02Phase 02

2. Combined Smart Jump-Cut Matrix

Generates a unified cut matrix combining dead air, 'um' / 'uh' vocal fillers, and repeated-word stutters with adjustable 0.08s–0.32s cushions.

03Phase 03

3. Paced Render & Timeline EDL Export

Audition the clean cut directly in your browser or export CMX 3600 EDL and XML marker files to finish editing in Premiere Pro, DaVinci Resolve, or Final Cut Pro.

Frequently Asked Questions

Common Questions & Technical Clarifications

How does the Rough Cut editor differ from simple silence removal?+

Traditional silence removers only detect volume drops. AutoSilenceCut's Smart Cut engine combines acoustic RMS energy scanning with word-level transcript analysis to identify both silent dead air and verbal filler sounds ('um', 'uh', 'you know', repeated stutters) in a single unified cut matrix.

How does speech cushioning prevent robotic or breathless jump cuts?+

Instead of hard-cutting the exact millisecond speech stops, AutoSilenceCut preserves a calibrated speech cushion (0.32s in Natural mode, 0.15s in Tight mode, 0.08s for filler words) to retain natural breathing decays and consonant tail harmonics.

Can I export my rough cut directly to Adobe Premiere Pro or DaVinci Resolve?+

Yes. In addition to exporting rendered audio directly in uncompressed 16-bit PCM WAV format, you can download CMX 3600 EDL, Final Cut Pro XML, and Audacity label tracks to import your cuts non-destructively into your NLE timeline.

Is there any watermark or file duration limit on rough cut exports?+

No watermark. AutoSilenceCut is 100% free with no subscription paywalls; source files can be up to 1 GB on desktop (250 MB on mobile).

Are my video files uploaded to third-party cloud servers?+

No. All media decoding, waveform analysis, and rough-cut slicing execute 100% locally in your web browser memory.
