# Video Edit Planner
|
|
|
|
An agent skill that helps plan video edits through iterative dialogue — transcribe audio, extract key frames on demand, analyze visuals, and produce a structured edit plan.
|
|
|
|
**Repository**: https://git.nite07.com/nite/video-edit-planner-skill
|
|
|
|
## Features
|
|
|
|
- **Audio transcription** — bundled [funasr-script](https://github.com/modelscope/FunASR) with Fun-ASR-Nano (high quality, Chinese-optimized) and SenseVoice (fast preview) models
|
|
- **On-demand frame extraction** — ffmpeg-based clip cutting (`-c copy`) + scene-change detection + uniform sampling, with hardware acceleration (CUDA/NVDEC preferred)
|
|
- **Artifact indexing** — SQLite database tracks all transcriptions, clips, and frames to avoid duplicate processing across sessions
|
|
- **Vision analysis guidance** — binary-search-style frame sampling strategy; works with any vision-capable model the agent's runtime provides
|
|
- **Iterative edit plans** — Markdown-table output (timecodes, segment descriptions, actions, transitions, notes) refined through follow-up questions
|
|
- **Agent-agnostic** — no platform-specific tool names; works with any agent framework (Hermes, Claude Code, Codex, etc.)
|

|
## Quick Start
|
|
|
|
### Prerequisites
|
|
|
|
| Dependency | Install |
|
|
|---|---|
|
|
| `ffmpeg` + `ffprobe` | Linux: `pacman -S ffmpeg` / `apt install ffmpeg`; macOS: `brew install ffmpeg`; Windows: `winget install Gyan.FFmpeg` |
|
|
| `uv` | Linux: `pacman -S uv`; macOS: `brew install uv`; Windows: `winget install astral-sh.uv`; fallback: `pip install uv` |
|
|
| `python3` | Linux: `pacman -S python`; macOS: `brew install python`; Windows: `winget install Python.Python.3` |
|
|
|
|
### Install the skill
|
|
|
|
Copy or clone this repository into your agent's skills directory. For Hermes Agent:
|
|
|
|
```bash
|
|
git clone mygit:nite/video-edit-planner-skill.git ~/.hermes/skills/media/video-edit-planner
|
|
```
|
|
|
|
### First use
|
|
|
|
The transcription scripts need a one-time dependency setup:
|
|
|
|
```bash
|
|
cd ~/.hermes/skills/media/video-edit-planner/scripts/transcription && uv sync
|
|
```
|
|
|
|
This creates an isolated venv with `funasr`, `torch`, `torchaudio`. If you've used these packages via uv before, the cache is reused — first-time cost is only the link step.
|
|
|
|
## Workflow
|
|
|
|
```
|
|
1. Check dependencies (ffmpeg, uv, python3)
|
|
2. Gather inputs (video path + audio track index)
|
|
3. Ask editing requirements
|
|
4. Transcribe audio (skip if cached in index)
|
|
5. Extract clips & frames on demand (agent decides when transcript is insufficient)
|
|
6. Analyze frames with vision model (binary-search-style sampling)
|
|
7. Produce Markdown-table edit plan + overall recommendation
|
|
8. Iterate — user asks follow-ups, plan is refined
|
|
```
|

## Index Database
|
|
|
|
All processing artifacts are tracked in an SQLite database (`<video_stem>.vedit.db`) stored next to the video file:
|
|
|
|
- **transcription** — JSON path, track index, duration
|
|
- **clips** — start/end time, file path, extraction reason
|
|
- **frames** — timestamp, file path, scene score, extraction method
|
|
|
|
This avoids re-transcribing or re-extracting frames for the same video across sessions.
