6missedcalls Video Editing
Edit videos using natural language instructions. Supports trimming, jump cuts (silence removal), captions with multiple styles, text overlays, and speed changes — all powered by ffmpeg and Whisper.
Usage
Give a video file path and describe what you want done:
Edit my video at ~/video.mp4 — remove silence, add Hormozi-style captions, and speed it up 1.25x
Trim ~/interview.mp4 from 00:02:00 to 00:15:00 and add standard captions
Add a "Subscribe!" text overlay at the 1 minute mark in ~/video.mp4
Capabilities
Trimming
Cut video to specific start/end timestamps or duration.
scripts/trim.sh video.mp4 --start 00:01:30 --end 00:05:00
Jump Cuts (Silence Removal)
Auto-detect and remove silent/dead-air sections. Configurable threshold, minimum silence duration, and padding.
scripts/jumpcut.sh video.mp4 --threshold -30 --duration 0.5 --padding 0.1
Captions
Transcribe audio with Whisper, then burn subtitles into video. Three caption styles:
| Style | Description |
|---|---|
| hormozi | Bold, centered, large — Alex Hormozi word-by-word impact style |
| standard | Traditional bottom subtitles with semi-transparent background |
| minimal | Small lower-third captions, clean and unobtrusive |
scripts/transcribe.sh video.mp4 --model base --language en
scripts/caption.sh video.mp4 video.srt --style hormozi
Text Overlays
Add text at specific positions and timestamps. Supports 7 positions: center, top, bottom, top-left, top-right, bottom-left, bottom-right.
scripts/overlay-text.sh video.mp4 --text "Subscribe!" --start 00:01:00 --end 00:01:05 --position bottom-right
Speed Changes
Adjust playback speed (audio pitch-corrected via atempo).
# Via edit.sh orchestrator
scripts/edit.sh video.mp4 --speed 1.5
Full Pipeline (Orchestrator)
Chain multiple operations in a single command:
scripts/edit.sh video.mp4 \
--trim-start 00:00:10 --trim-end 00:10:00 \
--jumpcut \
--caption --caption-style hormozi \
--speed 1.25 \
--overlay-text "Like & Subscribe" --overlay-start 00:01:00 \
--output final.mp4
Pipeline order: trim → jump cut → speed → caption → overlay
Requirements
- ffmpeg — video processing (must be installed)
- whisper — audio transcription for captions (openai-whisper CLI)

Agent Instructions
When the user asks to edit a video:
- Parse the request — identify which operations are needed (trim, jumpcut, caption, overlay, speed)
- Use edit.sh for multi-operation edits — it chains operations in the correct order
- Use individual scripts for single operations — faster, simpler output
- For captions: if the user has an existing SRT, use
--caption-srt; otherwise transcription runs automatically - Default caption style: use "standard" unless the user specifies a style
- Default whisper model: use "base" for speed; suggest "medium" or "large" for accuracy on long/noisy videos
- Output: always tell the user the output file path and duration
