So let’s talk about the colors. We must select intense, bright colors.

Since the original color scheme from the hero image is rather dull, we will use this shade of blue only. Let’s also pick some intense red and another shade of blue!

Let’s enter the thumbnail text.
It should be as short as possible. Top videos don’t have long sentences on their thumbnails. As people scroll down, they don’t have time to read long text.

Our hero image has an illustration style, so neon is not what we want. This text with the red hard shadow underneath looks like a good match. Let’s see some variations!
Let’s move the text a bit upward. Not bad at all; it looks like the cover of a comic book!

Since we already have the artwork and text in the works, why not go for one more?
Turning off the “Glitter” tag will eliminate those cinematic-style thumbnails. We want that comic book feeling, no gradient colors, or shiny effects.

Let’s try this one. Vary placement only.
Now let’s change the colors and fonts.

Since the text block is very big, there isn’t too much room for placement variations. Nevertheless, let’s see.
Click on one of the images to turn on manual placement mode. Shrink it. Perfect. Now let’s generate the image again.
And there we have a stylish thumbnail for our video! Let’s get the final image at 1280 by 720 pixels.

Maybe that red-blue letter version was even better? Let’s go back to the last four styles by selecting “get new styles”!
This one at the bottom. The colors and the font style look very good, so let’s just go for a different placement.
Again, it’s better to do this manually. The text block should be on the right side; all we need to do is shrink it.
Now we have two thumbnail images for conducting A B testing!

Hover over the panel icons for assistance. You can enable or disable any icon with a single click. Icons will affect the next generated set of images.
You can change the main colors using the color pickers.

Adjust shadows with the sliders. Remember to turn on the corresponding button to the left of each slider to enable the modifier. To completely remove the shadow, turn on the modifier and move the slider to the left. For stronger shadows, move the slider to the right. Changes will affect the next set of images.

To edit the thumbnail text, click on the ‘ENTER TEXT’ sign at the top of the panel.

To refine your style selection, you can disable any of the tag selectors such as ‘FUNNY,’ ‘PRO,’ ‘NEWS,’ or ‘GLITTER.’
• ‘FUNNY’ includes fun and comic-style templates.
• ‘PRO’ includes professional-looking, clean templates.
• ‘NEWS’ features attention-grabbing, energetic styles.
• ‘GLITTER’ offers cinematic, bright styles with light effects.

Make sure you selected the “Get new styles” option, and then click on the generate button to see the new set of designs.

When you see a promising style, select “Broad Variations”. Then click “Generate”. This will vary colors and fonts, using the same style.
To get yet another varations, select “Broad Variations” again, and click “Generate”. When you see a nice font and color combination, and you have an idea about the placements, click on the image.
This will invoke the manual edit mode. Now you can select the text block and move it around. Move the hero into the desired position. Using the sliders you can adjust the text size and angle, hero size and angle.
When you are done, please click on the “Generate” button. You will find the adjusted image in the topmost position. It is ready to create a final render.

You will be presented with four styles. If you don’t like any of them, select the ‘GET NEW STYLES’ option and then click on the ‘GENERATE’ button. Repeat this process until you find a style you like.
It doesn’t matter if the placement is off on the sample. You can adjust placements any time. It’s just the image style that matters.
