SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires ffmpeg, ffprobe, jq, node, and includes scripts (resource) and references (resource) components.

What problem does it solve? Editing talking-head videos manually is slow: you must scrub footage to find filler words, stutters, retakes, and silences, cut them without losing meaning, then rebuild subtitles and assemble the final video. This Skill automates that two-stage workflow from raw recording to exported MP4. ## Core Features & Use Cases - Speech Cleanup (Stage 1): Transcribes the raw video with word-level timestamps, detects deletion candidates (silences, filler words, stutters, repeated phrases, broken sentences, retakes), generates an HTML review page, and cuts a clean video with ffmpeg after user confirmation. - Risk-Tiered Deletion Rules: Applies a "delete earlier, keep later" principle and risk-tiered review so low-risk cuts (silences, short fillers) go straight to review while high-risk cuts (whole-sentence deletions) get adversarial verification. - Final Assembly (Stage 2): Builds a storyboard from the cut video, subtitles, and assets, previews a second-by-second timeline in HTML, and exports the final MP4 at the configured aspect ratio (e.g., 3:4 vertical). - Use Case: You recorded a 20-minute talking-head video full of "um", stutters, and repeated takes. The Skill transcribes it, proposes cuts, lets you confirm them in a review page, outputs a clean source_cut.mp4 with AI-proofread subtitles.srt, then assembles the final vertical video. ## Quick Start Ask the AI to cut this talking-head video by removing filler words and mistakes, then export the final vertical MP4 with subtitles.

Frequently Asked Questions about space-video-edit

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automatically remove filler words from a video?▼

Transcribe the video with word-level timestamps, detect filler words like "um" and "uh" plus silences and stutters, then cut the marked ranges with ffmpeg. This Skill generates a review page so you confirm deletions before the final cut.

How to cut video by keep ranges with ffmpeg?▼

Define the segments to keep as start/end times in a JSON file, then run the cut_by_ranges.sh script which re-encodes each segment with libx264 and concatenates them losslessly. This avoids the drift errors of deleting segments one by one.

Why should subtitles be re-transcribed after cutting a video?▼

Cutting changes the timeline, so subtitles from the original video no longer align with the audio. This Skill re-transcribes the cut video and runs AI proofreading to produce an accurate subtitles.srt file.

What tools are required for automated talking-head video editing?▼

You need ffmpeg and ffprobe for cutting and verification, jq for parsing range JSON, node for the review and timeline preview pages, and an ASR backend for word-level transcription.

When does automatic deletion risk removing real content?▼

Whole-sentence deletions and repeated sentences with diverging endings are high-risk because the later version may contain unique content. The Skill flags these for adversarial review while low-risk cuts like silences go straight to the manual review page.
