STEP 2
1. Pick a professional template

Browse through the available templates and choose one that closely aligns with your video’s goal. For instance, if you’re making a corporate explainer, select a business-focused layout. If it’s for social media, look for short, punchy formats. Make sure the template’s structure supports the tone and message you want to deliver.

You can usually preview or edit these elements before clicking on "Generate" to continue.
