# Thumbnails
### **What is a personalized thumbnail?**
Personalized thumbnails serve as customized previews of your video content, designed specifically for each recipient. They display a short, attention-grabbing snapshot of the video that can include the viewer’s name or a personalized message. Thus, making it far more engaging than a static image.
You can easily **copy these thumbnails** and **paste them directly** into your **email editor**, **WhatsApp**, or **Slack** to share personalized video previews seamlessly.
#### **Why Use Personalized Thumbnails?**
* Personalized thumbnails attract attention: **A thumbnail that includes the viewer’s name or company creates a sense** of “**this is for me,**” which drives **higher click-through rates**.
* They improve consistency across your campaign: When thumbnails match the personalization in the video itself (name, company, dynamic visuals), it strengthens the message and credibility.
* They reduce manual work: Instead of creating dozens or hundreds of static thumbnail images per recipient, the system lets you use variables and generate customized versions automatically.

#### **How to Set Up Personalized Thumbnails?**
**Step 1: Navigate to the Thumbnails Section**
* In your personalized project, go to the “**Settings**” tab and select the "**Thumbnail**" option.
**Step 2: Select the Thumbnail Preview type**
1. Studio by Gan.AI supports multiple thumbnail types for flexibility:
* **Static**: A still image from your video or a custom image upload (JPG/PNG).
* **Animated**: A short, silent GIF extracted from your video (movement can increase engagement).
* **Custom Upload**: Upload your own designed image (JPG/PNG) to act as the thumbnail.
* You can also select a specific part of the video to use as the preview.
* If you choose an animated preview, the selected segment will be generated as a GIF.
**Step 3: Personalized Thumbnail Text**
* In the “**Thumbnail Text**” field (or editable area), type your default text. For example: “**@FirstName** from **@Company** – Your personalized video is here”
* To insert a variable: **type @**, then select from the drop-down list (or **type the exact variable name**).
* You may use multiple variables in one thumbnail line if needed (e.g., @FirstName, @ProductName, @City).
* If you’re already using variables for subtitles or landing pages, you can reuse the same variable names here for consistency.
**Step 4: Edit Thumbnail Design**
* Click “**Edit Thumbnail Design**” to open the design editor.
* **Text Size:** Select an appropriate size for the text.
* **Text Color:** Choose contrast colours for readability (e.g., white text on dark background).
* **Text Transparency:** Adjust the Transparency for better readability.
* **Text Background / Padding:** Adjust padding or background colour/transparency for clarity. Text background can also be disabled here.
* **Positioning:** Drag and position the text box so it doesn’t overlap critical parts of the image or avatar.\
After editing, click Save Changes.
#### Best Practices for Thumbnail Personalized Setup
* Use **short and impactful text** — lengthy sentences may become unreadable in thumbnail format.
* Place your variable text in the top third or centre of the image so it remains visible in preview snippets across email clients or mobile devices.
* When using multiple variables, test examples with long values (e.g., long names or company names) to ensure the design accommodates all variations.
* Avoid placing the variable text near image edges or over busy backgrounds; ensure readability across devices.
* **Maintain brand consistency** — use your brand colours, logo, or fonts in the thumbnail design.
#### Troubleshooting Thumbnail Issues
| **Issue** | **Possible Fix** |
| ----------------------------------------------------- | ------------------------------------------------------------------------------------------------------- |
| Thumbnail image appears blurry or low quality | Use high resolution image for custom uploads. For GIFs, ensure source video quality is sufficient. |
| Multiple variables overlap or text becomes unreadable | Reduce number of variables, shorten text, increase font size or redesign layout to allow more space. |
| Animated thumbnail doesn’t play / appears as static | Confirm GIF format is supported; re-upload as animated type; test in your email client or landing page. |
| Thumbnail image appears blurry or low quality | Use high resolution image for custom uploads. For GIFs, ensure source video quality is sufficient. |
Personalized thumbnails are a simple but powerful way to boost engagement, making each viewer feel the content was created just for them. By combining variables, clean design, and consistent branding, you can generate high-impact thumbnail previews at scale—without manual editing. A well-designed personalized thumbnail not only increases click-through rates but also strengthens the overall experience across your personalized video campaign.
