Use it when the goal is not just "make an image," but "make a still that can earn attention in a feed." *** ### What Thumbnail Mode Is For Use Thumbnail Mode when you want to: * Generate YouTube thumbnail concepts. * Explore multiple thumbnail directions for the same video. * Create strong faces, subjects, backgrounds, and visual hooks. * Build thumbnail backgrounds with room for title text. * Use proven thumbnail patterns as inspiration. * Create A/B test options before committing to one design. Use a different workflow when:

*** ### Thumbnail Mode vs. Cinematic Lab Both can help with thumbnails, but they solve different problems. | Use Thumbnail Mode when... | Use Cinematic Lab when... | | ------------------------------------------------------------ | ------------------------------------------------------------------------------------ | | You want thumbnail-specific psychology and A/B variations. | You want a cinematic still, key art, or production frame. | | The thumbnail needs bold layout, contrast, and click appeal. | The image needs camera, lens, lighting, and filmic realism. | | You want multiple concepts quickly. | You want one strong hero frame to build around. | | The thumbnail is the final deliverable. | The frame may also become Motion Director, Multi-Cam, or AI Transition source media. | A strong workflow is to make the hero image in Cinematic Lab, then use Canvas Editor or Thumbnail Mode thinking to adapt it into a thumbnail. ***
### How Thumbnail Mode Works When Thumbnail Mode is enabled, Chat Video Pro adds a thumbnail strategy pass before image generation. It can: * Understand the topic, niche, and emotional angle. * Apply thumbnail best practices. * Improve the prompt for feed readability. * Suggest stronger subject, layout, contrast, and hook direction. * Generate multiple variations for A/B testing. * Use blueprint references when Blueprint mode is enabled. You still need to give it a clear idea. Thumbnail Mode improves a direction; it does not replace having a strong video promise. *** ### Thumbnail Mode Options #### Off Use Off for normal image generation or when editing an existing thumbnail. Best for: * Regular images. * Image-to-Image edits. * Canvas Editor refinements. * Backgrounds or assets that are not thumbnails. #### On Use On when you want thumbnail optimization without visual blueprint references. Best for: * Quick thumbnail concepts. * A clear idea that needs better execution. * Faster generation. * Testing hooks, poses, backgrounds, or visual metaphors. #### On With Blueprints Use On with Blueprints when you want the generation to use proven thumbnail layouts or style references as inspiration. Best for: * Professional thumbnail ideation. * Finding a stronger layout direction. * Matching a proven thumbnail style. * Exploring formats you would not have prompted manually. Blueprints should inspire the structure, not copy another creator's thumbnail exactly.
*** ### Good Thumbnail Inputs A strong thumbnail prompt usually includes:
InputWhat to include
TopicWhat the video is about.
PromiseWhat viewers get if they click.
SubjectPerson, object, product, scene, or visual focus.
EmotionSurprise, curiosity, urgency, confidence, skepticism, tension, relief.
CompositionClose-up face, split screen, object hero, before/after, empty text space.
Visual hookWhat makes the thumbnail understandable in one second.
Useful structure: {% code overflow="wrap" %} ``` Create a YouTube thumbnail for [video topic] that communicates [promise]. Show [subject/scene] with [emotion], high contrast, clear focal point, and space for short title text. ``` {% endcode %} *** ### Prompt Examples #### Creator / Talking Head {% code overflow="wrap" %} ``` Create a YouTube thumbnail for a video about fixing bad AI video results. Show a frustrated creator looking at a messy generated clip on a monitor, high contrast, expressive face, red warning accents, clean empty space on the left for title text. ``` {% endcode %} Why it works: * It names the video promise. * It gives a human emotion. * It leaves room for final text. #### Product / Review {% code overflow="wrap" %} ``` Create a YouTube thumbnail for a camera review comparing a cheap lens to an expensive lens. Show both lenses large in the foreground, dramatic split-lighting, clear versus composition, premium tech-review style, bold negative space for text. ``` {% endcode %} Why it works: * It sets up a comparison. * It uses a simple visual structure. * It gives the viewer a reason to be curious. #### Tutorial / Outcome {% code overflow="wrap" %} ``` Create a YouTube thumbnail for a Premiere Pro tutorial about cutting podcasts faster with AI. Show a timeline transforming from messy to clean, a confident editor at the desk, bright green success accents, clean professional YouTube tutorial style. ``` {% endcode %} Why it works: * It visualizes the result. * It avoids a generic "person at computer" prompt. * It gives the image a before/after idea. #### Cinematic Thumbnail Background {% code overflow="wrap" %} ``` Create a dramatic 16:9 thumbnail background for a video about relighting dull footage. Show a split scene with flat gray lighting on one side and cinematic golden rim light on the other, no text, strong contrast, clean center subject. ``` {% endcode %} Why it works: * It asks for a background, not final text. * It creates a clear before/after visual hook. * It is ready for manual title placement. ***
### Multi-Thumbnail Variations When you request multiple thumbnails, Thumbnail Mode can create different approaches to the same idea. Ask for variations when you are not sure which angle is strongest. Examples: ``` Create 4 thumbnail variations for this video idea, each with a different visual hook. ``` {% code overflow="wrap" %} ``` Generate 3 A/B thumbnail options: one emotional face version, one object-focused version, and one before/after version. ``` {% endcode %} Good variation types:
VariationBest for
Reaction faceCreator-led videos, drama, surprise, opinion, mistakes.
Before/afterTutorials, transformations, editing workflows, results.
Versus/comparisonReviews, tool comparisons, "A vs B" concepts.
Hero objectProduct, software, gear, plugins, visual effects.
Mystery/curiosityStory videos, reveals, experiments, unusual results.
Do not generate four nearly identical thumbnails. Ask for different hooks, not just different colors. *** ### Choosing A Model Use models based on the hardest part of the thumbnail.

For final thumbnail text, manual typography is often still the best choice. Generate the visual, then add exact text in Canvas Editor, Premiere, Photoshop, or your design tool. ***
### Editing A Thumbnail Drag the image back into the composer to continue editing. #### Quick Prompt Edit 1. Re-attach or reuse the generated thumbnail. 2. Turn Thumbnail Mode **Off**. 3. Use Image-to-Image for a focused edit. 4. Prompt the exact change. Example: ``` Make the background darker and keep the person's face, pose, and layout unchanged. ``` #### Precise Canvas Edit 1. Click **Edit** on the thumbnail. 2. Use Canvas Editor. 3. Mark the exact area to change. 4. Add or adjust text, objects, arrows, products, or cutouts. For precision edits, keep Thumbnail Mode Off unless you intentionally want to generate a new optimized thumbnail direction. #### Cutout Workflow 1. Use Background Removal to isolate a person or product. 2. Place the cutout on a bold thumbnail background. 3. Add title text and accents. 4. Upscale the final thumbnail if needed. This is often better than asking one prompt to do everything. *** ### Best Practices #### Make The Promise Visual The thumbnail should show the reason to click. "Premiere Pro tutorial" is a topic. "Messy timeline becomes clean in one click" is a visual promise. #### Use Fewer Elements Small thumbnails punish clutter. One face, one product, one strong before/after, or one clear visual metaphor usually beats a busy scene. #### Leave Room For Text If you plan to add title text later, prompt for empty space. Say `clean empty space on the left for title text` or `simple background with room for two large words`. #### Treat Text As A Finishing Step AI can generate text, especially with GPT Image 2, but final thumbnail typography often looks best when added manually. #### Generate Concepts Before Polishing Use Thumbnail Mode for exploration. Pick the strongest concept, then refine it with Image-to-Image, Canvas Editor, Background Removal, and Upscaling. #### Match The Hook To The Video Do not make a thumbnail promise the video does not pay off. Strong thumbnails create clicks, but accurate thumbnails create trust. *** ### Common Workflows #### Fast Thumbnail Concept 1. Enable Generate Media. 2. Choose a supported image model. 3. Turn Thumbnail Mode On. 4. Prompt the topic, promise, subject, and emotion. 5. Generate 2-4 options. #### Cinematic Thumbnail 1. Use Studio Cinematic Lab for the hero frame. 2. Save the best still. 3. Use Canvas Editor to add layout, cutouts, or text space. 4. Add final text manually or with GPT Image 2. 5. Upscale when approved. #### Thumbnail With Cutout Subject 1. Generate or upload a subject image. 2. Use Background Removal to create a transparent cutout. 3. Generate or design the background. 4. Compose in Canvas Editor. 5. Finish with Image Upscaling if needed. *** ### Troubleshooting #### Thumbnail Mode Is Not Available Use Generate Media and choose a supported image model. Availability can vary by model and release. #### The Thumbnail Looks Generic Add a clearer promise, emotion, and composition. Instead of `thumbnail for AI editing`, try `frustrated editor looking at a broken AI clip, red warning symbols, clear before/after layout`. #### The Text Is Wrong Use GPT Image 2 for text-heavy generations, keep generated text short, or add final text manually after generation. #### Variations Look Too Similar Ask for different concepts, not just multiple outputs. Specify variation types: reaction face, before/after, product hero, versus, mystery, or tutorial outcome. #### The Result Is Too Busy Reduce the number of subjects, simplify the background, and leave more negative space. Thumbnails must read quickly at small size. #### I Need To Edit A Thumbnail Turn Thumbnail Mode Off and use Image-to-Image or Canvas Editor. Thumbnail Mode is best for generating new thumbnail concepts. *** ### Related Pages * [Image Generation ](/features/image-generation.md)- Create and edit still images. * [Supported Image Models](/features/image-generation/supported-image-models.md) - Choose a model for thumbnail generation. * [Text-to-Image](/features/image-generation/text-to-image.md) - Create normal prompt-based images. * [Canvas Editor](/features/image-generation/canvas-editor.md) - Make precise thumbnail edits. * [Background Removal ](/features/image-generation/background-removal.md)- Create cutout subjects. * [Image Upscaling](/features/image-generation/image-upscaling.md) - Finish approved thumbnails at higher resolution. * Studio Cinematic Lab - Create cinematic stills and hero frames. * High-CTR Thumbnail Workflow - Full thumbnail production workflow. *** **Next:** Use Canvas Editor for precise layout edits, or Image Upscaling when the final thumbnail needs more resolution. --- # Agent Instructions This documentation is published with GitBook.
