Short Video Creator
Creates short videos for social media platforms. Analyzes content, adapts to platform specs, generates prompts, and calls tuzi-video-gen backend.
Script Directory
This is a workflow-only skill (no scripts). It delegates video generation to tuzi-video-gen.
VIDEO_GEN_DIR: Resolve from skills/tuzi-video-gen/SKILL.md relative to project root.
Step 0: Load Preferences ⛔ BLOCKING
CRITICAL: This step MUST complete BEFORE any video generation.
0.1 Check API Key
echo "${TUZI_API_KEY:-not_set}"
grep -s TUZI_API_KEY .tuzi-skills/.env "$HOME/.tuzi-skills/.env"| Result | Action |
|---|---|
| Key found | Continue to Step 0.2 |
| Key NOT found | ⛔ Run API key setup (see references/config/first-time-setup.md) |
0.2 Check EXTEND.md
test -f .tuzi-skills/tuzi-short-video/EXTEND.md && echo "project"
test -f "$HOME/.tuzi-skills/tuzi-short-video/EXTEND.md" && echo "user"| Result | Action |
|---|---|
| Found | Load, parse, apply settings |
| Not found | ⛔ Run first-time setup (references/config/first-time-setup.md) |
| Path | Location |
|---|---|
.tuzi-skills/tuzi-short-video/EXTEND.md | Project directory |
$HOME/.tuzi-skills/tuzi-short-video/EXTEND.md | User home |

Step 1: Analyze User Input
Analyze the user's content (text, article, script, topic description):
- Identify main topic and key points
- Determine content type (tutorial, story, showcase, explainer)
- Estimate ideal video length and segment count
Step 2: Confirm Platform and Parameters
Use AskUserQuestion to let user choose target platform (unless specified or saved in EXTEND.md):
header: "Target Platform"
question: "目标发布平台？"
options:
- label: "小红书"
description: "9:16 竖屏, 720x1280"
- label: "抖音"
description: "9:16 竖屏, 1080x1920"
- label: "X/Twitter"
description: "16:9 横屏, 1280x720"
- label: "视频号"
description: "9:16/16:9, 1080x1920"Platform Presets
| Platform | Aspect | Size | Duration | Notes |
|---|---|---|---|---|
| 小红书 | 9:16 | 720x1280 | 15-60s | 竖屏短视频 |
| 抖音 | 9:16 | 1080x1920 | 15-60s | 竖屏，高分辨率 |
| X/Twitter | 16:9 | 1280x720 | 5-140s | 横屏为主 |
| 视频号 | 9:16 | 1080x1920 | 15-60s | 竖屏优先 |

Step 3: Generate Video Script
Based on content analysis and platform:
Single Video (content fits one clip)
- Write a detailed video generation prompt in English
- Include: visual scenes, camera movements, style, mood, lighting
- Save prompt to
prompts/01-video-prompt.md
Long Video (content needs multiple segments)
- Split content into logical segments (opening + body + ending)
- Write per-segment prompts with continuity notes
- Save to
prompts/01-segment-opening.md,02-segment-main.md, etc.
Workflow details: See references/workflows/
Step 4: Generate Video
Single Video
npx -y bun ${VIDEO_GEN_DIR}/scripts/main.ts \
--promptfiles <output-dir>/prompts/01-video-prompt.md \
--video <output-dir>/01-video-<slug>.mp4 \
--size <platform-size> \
--seconds <duration>Long Video
npx -y bun ${VIDEO_GEN_DIR}/scripts/main.ts \
--video <output-dir>/01-video-<slug>.mp4 \
--segments <N> \
--segment-prompts <output-dir>/prompts/01-segment-opening.md <output-dir>/prompts/02-segment-main.md ... \
--size <platform-size> \
--seconds <per-segment-seconds>Step 5: Completion Report
