Create Stunning YouTube Thumbnails with the ashesashes/yt-thumbs Cognitive Actions

In the world of digital content creation, having eye-catching visuals is essential for engagement. The ashesashes/yt-thumbs Cognitive Actions provide developers with powerful tools to create custom YouTube-style thumbnails. These actions allow for image processing and inpainting with various parameters, enabling you to produce high-quality, tailored thumbnails that stand out. With just a few lines of code, you can integrate these capabilities into your applications and enhance the visual appeal of your video content.

Prerequisites

Before getting started with the ashesashes/yt-thumbs Cognitive Actions, ensure you have the following:

  • An API key for accessing the Cognitive Actions platform.
  • Familiarity with making HTTP requests and handling JSON data.

Authentication usually involves passing your API key in the headers of your requests, which will allow you to access the actions securely.

Cognitive Actions Overview

Generate Custom YT Thumbnail

The Generate Custom YT Thumbnail action allows you to create a custom thumbnail by processing and inpainting images. It offers flexible control over parameters such as image masks, aspect ratios, output formats, and quality. You can choose between the 'dev' model for high-quality generation or the 'schnell' model for quicker results. This action also provides control over LoRA weights and strengths for refined outputs.

Input

The input schema for this action requires the following fields:

  • prompt (required): A descriptive text prompt guiding the image generation.
  • model (optional): Select between 'dev' or 'schnell'.
  • imageFormat (optional): Choose the output format (webp, jpg, png).
  • outputCount (optional): Specify the number of images to generate.
  • guidanceScale (optional): Sets the guidance scale for diffusion.
  • outputQuality (optional): Specifies the quality for saving output images.
  • imageAspectRatio (optional): Select the image's aspect ratio.

Here's an example input JSON payload:

{
  "model": "dev",
  "goFast": false,
  "prompt": "A gamer in the YTHUMBS style mid-scream, wearing a headset, lit by RGB lights, with an intense action scene reflected in their glasses, surrounded by motion lines and a dramatic 'UNBELIEVABLE!' text overlay. no watermarks",
  "imageFormat": "jpg",
  "outputCount": 1,
  "guidanceScale": 3,
  "outputQuality": 80,
  "promptStrength": 0.8,
  "imageResolution": "1",
  "imageAspectRatio": "16:9",
  "mainLoraIntensity": 1,
  "inferenceStepCount": 28,
  "additionalLoraIntensity": 1
}

Output

The action typically returns a URL to the generated thumbnail image. Here’s an example of an output URL:

[
  "https://assets.cognitiveactions.com/invocations/3f235359-37b6-44f3-9b3e-735f12e493f0/7f94e272-dfaa-473a-be2e-99c9c6166d88.jpg"
]

Conceptual Usage Example (Python)

Here’s a conceptual example of how you might call the Generate Custom YT Thumbnail action using Python:

import requests
import json

# Replace with your Cognitive Actions API key and endpoint
COGNITIVE_ACTIONS_API_KEY = "YOUR_COGNITIVE_ACTIONS_API_KEY"
COGNITIVE_ACTIONS_EXECUTE_URL = "https://api.cognitiveactions.com/actions/execute" # Hypothetical endpoint

action_id = "e68ecdb3-1dd7-4f95-85d0-3adef92cfc09" # Action ID for Generate Custom YT Thumbnail

# Construct the input payload based on the action's requirements
payload = {
    "model": "dev",
    "goFast": False,
    "prompt": "A gamer in the YTHUMBS style mid-scream, wearing a headset, lit by RGB lights, with an intense action scene reflected in their glasses, surrounded by motion lines and a dramatic 'UNBELIEVABLE!' text overlay. no watermarks",
    "imageFormat": "jpg",
    "outputCount": 1,
    "guidanceScale": 3,
    "outputQuality": 80,
    "promptStrength": 0.8,
    "imageResolution": "1",
    "imageAspectRatio": "16:9",
    "mainLoraIntensity": 1,
    "inferenceStepCount": 28,
    "additionalLoraIntensity": 1
}

headers = {
    "Authorization": f"Bearer {COGNITIVE_ACTIONS_API_KEY}",
    "Content-Type": "application/json"
}

try:
    response = requests.post(
        COGNITIVE_ACTIONS_EXECUTE_URL,
        headers=headers,
        json={"action_id": action_id, "inputs": payload} # Hypothetical structure
    )
    response.raise_for_status() # Raise an exception for bad status codes (4xx or 5xx)

    result = response.json()
    print("Action executed successfully:")
    print(json.dumps(result, indent=2))

except requests.exceptions.RequestException as e:
    print(f"Error executing action {action_id}: {e}")
    if e.response is not None:
        print(f"Response status: {e.response.status_code}")
        try:
            print(f"Response body: {e.response.json()}")
        except json.JSONDecodeError:
            print(f"Response body: {e.response.text}")

In this Python snippet:

  • Replace YOUR_COGNITIVE_ACTIONS_API_KEY with your actual API key.
  • The action_id variable should correspond to the Generate Custom YT Thumbnail action.
  • The payload variable is constructed using the example input schema provided.
