AI Game Trailer

AI Game Trailer

Create cinematic game promotional trailers and teaser clips using each::sense — the intelligent AI agent that automatically selects the best model for your request.

Quick Start

Requires an each::labs API key. Get one at eachlabs.ai.

Using curl

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": "Generate a cinematic game trailer clip: a lone warrior in dark armor walks through a burning medieval village at night, embers floating upward, camera slowly tracking alongside them. The warrior draws a glowing runic sword as a massive dragon shadow passes overhead. Dark fantasy, cinematic widescreen, dramatic orchestral mood, 4K quality"
      }
    ],
    "stream": false
  }'

Using Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_EACHLABS_API_KEY",
    base_url="https://eachsense-agent.core.eachlabs.run/v1"
)

response = client.chat.completions.create(
    model="eachsense/beta",
    messages=[{
        "role": "user",
        "content": "Generate a cinematic game trailer clip: a lone warrior in dark armor walks through a burning medieval village at night, embers floating upward, camera slowly tracking alongside them. The warrior draws a glowing runic sword as a massive dragon shadow passes overhead. Dark fantasy, cinematic widescreen, dramatic orchestral mood, 4K quality"
    }]
)

print(response.choices[0].message.content)

With Reference Image

Provide concept art or a game screenshot to generate a trailer from that visual:

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": [
              {"type": "text", "text": "Generate a cinematic game trailer clip based on this concept art. Bring the scene to life: add slow camera movement pushing forward, atmospheric particle effects, subtle character motion, and dramatic lighting. Cinematic widescreen format, game trailer quality."},
              {"type": "image_url", "image_url": {"url": "https://example.com/game-concept-art.jpg"}}
            ]
          }
    ],
    "stream": false
  }'

Images are sent inside messages using the OpenAI multimodal content format. Maximum 4 images per request.

Streaming

Set "stream": true for real-time SSE responses, or "stream": false for complete result in a single response. Streaming is useful for showing progress in UIs; non-streaming is simpler for scripts and automation.

Multi-Shot Trailer Workflow

GAME_STYLE="dark fantasy action RPG, cinematic widescreen, film grain, orchestral mood, 4K"

SHOTS=(
  "Shot 1 — Establishing: aerial camera slowly descends over a fog-covered cursed kingdom with twisted black towers, dead forests, and a blood-red moon"
  "Shot 2 — Character reveal: a cloaked figure stands at the edge of a cliff, wind blowing their cloak, camera pushes in from behind to reveal a scarred face and glowing eyes"
  "Shot 3 — Action montage: rapid sequence of sword clashes, dodge rolls, magic spells detonating, and enemies being launched, fast-paced cuts"
  "Shot 4 — Emotional beat: the character kneels before a fallen companion in a rainy battlefield, slow motion raindrops, close-up on clenched fist"
  "Shot 5 — Boss reveal: camera tilts up from ground level to show an enormous demon lord wreathed in black flame, towering over the hero, dramatic back-lighting"
  "Shot 6 — Final stinger: the hero charges forward with sword drawn, screen smashes to black just before impact"

Post-Production Notes

AI-generated trailer clips are individual scenes. To create a full trailer:

1. Generate individual clips — one scene per API call
2. Edit in video software — sequence clips, add transitions, adjust pacing
3. Add title cards and text — game title, release date (AI text is unreliable)
4. Layer audio — music, sound effects, voice-over
5. Color grade — unify the look across all clips

Common Pitfalls

• Too much action in one clip — each generation is a short clip. One focused action per scene works best.
• Text and logos will not render reliably. Add titles in post-production.
• Character consistency — the same character may look different across clips. Describe them identically each time.
• Audio is not generated. Plan for separate music and sound design.
• Pacing — AI generates at a constant tempo. Fast-paced montages need to be assembled from separate short clips in editing.
