A trailer that sells, made from the clips you already have
Most indie trailers follow the same shape because it works: open on the best moment, show the name, explain the game in three short beats, speed up into a climax and end on the logo with one clear ask. This tool builds that shape for you. You bring gameplay clips and a few lines of text. It cuts every shot on the beat of the music, so even a quick edit feels intentional.
Styles
Hype is fast: cuts every bar, white flashes, punchy text and a double-time climax over a driving beat. Good for action, roguelikes and anything with combat. Epic is slow and wide: cinema bars, crossfades, big serif titles and a deep drum soundtrack. Good for story, adventure and strategy. Cozy is soft: gentle fades, rounded text and a warm plucked tune. Good for farming, building and puzzle games.
Tips for a Steam trailer
Steam plays the first trailer muted in the store page and in search, so the first seconds have to work without sound. Start with gameplay, not a studio logo. Keep the title card short. Put your strongest clip first, because the first shot is reused as the opening. Use real gameplay rather than menus, and record clips at 1080p or higher with the interface you want people to see. Steam accepts the 1920 × 1080 MP4 this tool exports.
Using your own music
Choose My music and drop a track. The tool finds its tempo and first beat and moves every cut onto the beat. Song length makes the trailer as long as the track. Only use music you have the rights to. The built-in soundtrack is generated in your browser for each trailer, so there is nothing to license.
Is my footage uploaded?
No. Decoding, editing, music and encoding all happen in your browser. Your clips never leave your device.
