- Assemble a narrated video from a TOML project file using the committed assembler script. Use when the user says /assemble-video and provides an android.toml or ios.toml path, or wants to generate audio for the audio-first workflow.
Assemble Video from TOML Project
Runs scripts/assemble_video.py to assemble per-scene video clips with AI-generated voiceover narration and branding jingles into a final MP4.
Prerequisites
ffmpegon PATH- Python 3.11+ (for
tomllib) OPENAI_API_KEYin~/.secretspip install openai- Pre-recorded video clips (use
/record-clipsto create them)
Workflow
Full assembly (clips already recorded)
source ~/.secrets
python3 scripts/assemble_video.py docs/videos/<feature>/android.toml
Replace android.toml with ios.toml for iOS videos.
The script:
- Generates missing TTS audio from narration text
- Pads each clip with
tpadto match narration duration - Concatenates scenes using the ffmpeg
concatfilter - Adds branding jingles (intro/outro)
- Reports output path, duration, and size
Audio-first workflow (recommended)
Generate audio first to know exact clip durations before recording:
# Step 1: Generate audio, print required clip durations
source ~/.secrets
python3 scripts/assemble_video.py docs/videos/<feature>/android.toml --audio-only
# Step 2: Record clips using the printed durations
# Use /record-clips skill
# Step 3: Assemble final video
python3 scripts/assemble_video.py docs/videos/<feature>/android.toml
TOML Project Format
Each feature has per-platform TOML files in docs/videos/<feature>/:
android.toml-- Android-specific scenes, recording notes, and resolutionios.toml-- iOS-specific scenes, recording notes, and resolution
Audio (audio/ directory) is shared across platforms since narration is platform-agnostic.
[project]
title = "Feature Name - Ukulele Companion"
output = "../../feature-videos/android/feature-name.mp4"
resolution = "1080x2424"
[branding]
intro = "../../jingle-intro.wav"
outro = "../../jingle-outro.wav"
[voiceover]
model = "tts-1-hd"
voice = "nova"
volume_boost = 3.0
[[scene]]
name = "scene-name"
video = "clips/android/01-scene.mp4"
audio = "audio/01-scene.mp3"
narration = """Narration text."""
delay = 1.0
min_clip_duration = 25
See existing projects at docs/videos/explorer/android.toml and docs/videos/tuner/android.toml for full examples.
Creating a New Video Project
- Create the directory:
mkdir -p docs/videos/<feature>/clips/android docs/videos/<feature>/clips/ios docs/videos/<feature>/audio - Write
android.toml(and/orios.toml) with scenes and narration - Run
--audio-onlyto generate audio and see required clip durations - Use
/record-clipsto record scene clips - Run the assembler to produce the final video
