+# Video Editor Skill
+
+This skill automates the process of retrieving video footage, generating subtitles, and performing logical edits based on audio and caption content.
+
+## Workflow
+
+1. **Retrieve Footage**:
+   - Use `vps_exec` to run `gws download <file_id>` on the VPS.
+   - Verify the file is downloaded to the VPS workspace.
+
+2. **Isolate Audio**:
+   - Use `vps_exec` with `ffmpeg` to extract audio:
+     `ffmpeg -i input.mp4 -vn -acodec pcm_s16le -ar 16000 -ac 1 output.wav`
+
+3. **Generate Subtitles (.srt)**:
+   - **For Long Gameplay (2-5 hours)**: Do NOT use managed APIs due to duration limits and costs. Use local offline processing.
+   - Run `whisper.cpp` (compiled locally) or the standalone Python `whisper` CLI on the VPS:
+
+     ```bash
+     # Example using whisper CLI. Consider chunking the WAV if memory is constrained.
+     vps_exec "whisper output.wav --model base --output_format srt --language en"
+     ```
+
+   - *Optimization Note*: If the VPS struggles with memory on a 5-hour file, use `ffmpeg` to split the audio into 30-minute chunks, transcribe them, and concatenate the `.srt` files adjusting timestamps accordingly.
+   - Clean up subtitles if needed for Vegas 23 compatibility.
+
+4. **Logical Cutting**:
+   - Analyze the `.srt` and audio for silence or specific keywords (e.g., "boss", "death").
+   - Generate complex `ffmpeg` filter scripts or concat files based on timestamps.
+   - Taxonomy for markers:
+     - Boss Fights: `start_time`, `end_time`, `boss_name`, `result`.
+     - Player Death: `timestamp`, `cause_of_death`.
+     - Progression: `timestamp`, `item_acquired / milestone_reached`.
+     - Transitions: `timestamp`, `biome_change`.
+     - Events: `timestamp`, `event_name`.
+
+5. **Execute Edits**:
+   - Run the final `ffmpeg` command on the VPS to produce the edited video and audio package.
+
+6. **Upload to Google Drive**:
+   - Use `vps_exec` to run `gws upload <edited_video>` to sync the results back to Google Drive.
+
+## Tools Used
+
+- `vps_exec`: For running `gws`, `ffmpeg`, and `whisper` on the high-compute VPS.
+- `google`: For listing Drive files if needed (though `gws` is preferred on VPS).
+- `read_file` / `write_file`: For local log/metadata management.
