OpenClip is particularly effective for online course trailers, event highlight previews, documentary teasers, webinar promotions, keynote previews, and branded video campaigns. Any long-form video with strong spoken moments is a great candidate. ### Can I create multiple trailer versions from the same video? Yes. OpenClip surfaces 5-15 clip candidates per upload, each scored independently. You can select different clips for different platforms or audiences and export each as a standalone trailer. ### Does OpenClip edit clips together into a single montage trailer? OpenClip extracts individual clip segments scored for trailer potential. It does not merge multiple clips into a single montage sequence — each export is a standalone clip from your original footage. For montage-style trailers, you'd use the individual clips as source material in a separate editor. ### How does AI know which moments work as trailers? OpenClip's AI model analyzes the transcript of your video and scores each segment based on hook strength (how engaging the opening line is), narrative completeness (does the clip tell a mini-story), and viral potential (is it surprising, emotional, or valuable enough to share). ### What caption style works best for trailers? For high-energy promotional trailers, the 'Beast', 'Pop', and 'Kendrick' presets create a bold, cinematic feel. For professional or B2B trailers, 'Default' or 'Dan' offer a cleaner look. All presets can be previewed before you commit. ### Which OpenClip plan should I use for regular trailer creation? The Pro plan is well-suited for creators and marketers producing trailers regularly. If you're creating trailers for multiple clients or products simultaneously, the Business plan's batch processing handles multiple uploads at once. ### Can I use OpenClip to create trailers for courses or digital products? Absolutely. Course creators frequently use OpenClip to extract the most compelling lesson snippets or instructor moments from full course recordings and turn them into promotional trailers for sales pages and social media. ## Create Your First AI-Powered Trailer Today Upload your video and let OpenClip find the moments that will make your audience stop scrolling and click play.
