TrailerSmith

TrailerSmith is a game trailer maker that turns raw gameplay footage into a real indie game trailer in minutes. Drop in your gameplay clips and this auto trailer cutter finds the best moments, syncs cuts to your music's beat, and assembles a complete trailer — title cards, feature cards, and end card included.

How it works: TrailerSmith's excitement analysis scores every second of your footage, beat detection maps your music's rhythm, and beat-snapped cuts assemble a gameplay-to-trailer edit that feels professionally cut.

The free demo includes:

• Up to 2 clips

• 30-second standard preset

• Watermarked WebM export

100% offline — a single HTML file. Nothing ever leaves your machine. No account, no uploads, no cloud rendering.
