Frequently Asked Questions
What makes a useful thumbnail prompt?
Use one focal subject, a clear emotion, strong contrast, a simple background and a stated area for your final title.
Can the generator add the video title?
Generated lettering may be inaccurate. Create the image concept here, then add the final title with readable typography in your editor.
Which ratio should I use?
Use the landscape option when it matches your video placement, then confirm the current platform requirements before publishing.
Can I make several thumbnail options?
Yes. Keep the topic consistent and vary the focal subject, expression, color contrast or composition to create alternatives.
