# Shorts बनाएं

> compose_video के साथ 30–90s vertical shorts बनाएं — terminal tool tips, hybrid B-roll, AI images, और CTA endings।

Short-form explainers (YouTube Shorts, Reels, TikTok) उसी `compose_video`
pipeline का उपयोग करते हैं जो long explainers करते हैं, केवल कम scene counts और वैकल्पिक 9:16 output के साथ।

**Shorts के लिए अच्छे defaults:** 4–5 scenes, कुल 30–90s, `--no-text`
(केवल voiceover), hybrid B-roll या `--ai-images-only`।

```bash theme={null}
arka compose_video check   # ffmpeg, Pillow, stock keys
```

यह भी देखें: hybrid mode, custom script APIs, और env vars के लिए [Video बनाएं](/hi/guides/compose-video)।

## Quick recipe (LLM script)

```bash theme={null}
arka compose_video compose \
  --topic "fzf terminal fuzzy finder for developers" \
  --llm --scenes 4 --duration 60s \
  --no-text \
  -o fzf-short.mp4
```

Hybrid mode (default) प्रति scene stock **video** और **photo** B-roll mix करता है। जब आप stock photos के बजाय
Gemini/Pollinations images चाहते हैं तो `--ai-images-only` जोड़ें
(`GEMINI_API_KEY` या `POLLINATIONS_API_KEY` की आवश्यकता है)।

```bash theme={null}
arka compose_video compose \
  --topic "fzf terminal fuzzy finder" \
  --llm --scenes 5 --duration 75s \
  --no-text --ai-images-only \
  -o fzf-short-ai.mp4
```

## Terminal tool short (custom script + CTA)

Repeatable shorts (intro → value → install tip → like/subscribe) के लिए, `--llm` के बजाय JSON
script का उपयोग करें। Narration को punchy रखें; अंतिम scene आपका CTA है।

`terminal-short-script.json`:

```json theme={null}
{
  "scenes": [
    {
      "title": "Meet fzf",
      "narration": "fzf is a command-line fuzzy finder that makes searching files, history, and processes blazing fast.",
      "image_query": "terminal fuzzy search developer dark theme",
      "duration": 8
    },
    {
      "title": "Why devs love it",
      "narration": "Pipe any list into fzf, type a few letters, and jump exactly where you need.",
      "image_query": "developer terminal workflow productivity",
      "duration": 10
    },
    {
      "title": "Try it today",
      "narration": "Install with your package manager, bind Ctrl-R for history search, and never hunt through output again.",
      "image_query": "install terminal tool command line",
      "duration": 8
    },
    {
      "title": "Stay tuned",
      "narration": "If this helped, like and subscribe for more terminal tips and dev tools.",
      "image_query": "subscribe like notification",
      "duration": 10
    }
  ]
}
```

```bash theme={null}
arka compose_video compose \
  --script terminal-short-script.json \
  --no-text \
  -o fzf-short.mp4
```

जब आप explicit control चाहते हैं तो प्रति scene `media_type` set करें (`video` for motion B-roll,
`image` for diagrams or UI stills)। देखें [Video बनाएं](/hi/guides/compose-video#hybrid-mode-default)।

## Vertical 9:16 (Shorts / Reels)

`compose_video` में अभी तक कोई `--orientation` flag नहीं है। Portrait output और
vertical stock search के लिए env vars set करें:

```bash theme={null}
VIDEO_ORIENTATION=portrait VIDEO_WIDTH=1080 VIDEO_HEIGHT=1920 \
  arka compose_video compose \
  --script terminal-short-script.json \
  --no-text \
  -o fzf-short-vertical.mp4
```

**Full AI video** clips (stock B-roll नहीं) के लिए, `VIDEO_ASPECT=9:16` के साथ `ai_video` का उपयोग करें:

```bash theme={null}
VIDEO_ASPECT=9:16 arka ai_video "cinematic terminal hacker desk neon" -d 8 -o clip.mp4
```

## उपयोगी flags & env

| Flag / env                           | Shorts में उपयोग                                              |
| ------------------------------------ | ------------------------------------------------------------- |
| `--scenes 4`                         | Auto scene count override करें (\<90s के लिए explicit ठीक है) |
| `--duration 60s`                     | Target runtime (`30s`, `90s`, `1m30s`)                        |
| `--no-text`                          | केवल voiceover — hybrid mode में default                      |
| `--ai-images-only`                   | AI-generated scene images                                     |
| `VIDEO_MODE=hybrid`                  | Stock video + photos (default)                                |
| `VIDEO_SCENE_SEC=5`                  | जब scene में duration set न हो तब प्रति scene default seconds |
| `PEXELS_API_KEY` / `PIXABAY_API_KEY` | Hybrid B-roll के लिए stock video                              |

Natural language भी सही रूप से route होती है:

```bash theme={null}
arka "make a 60 second video about fzf with no text, 4 scenes"
```
