Best AI video and trailer tools for indie game devs
A short trailer or devlog clip does a lot of work on a Steam page or social feed. These are the AI video tools in the ToolDrop directory. Runway (free tier, from $15/mo), Pika (free tier) and Kling AI (free Basic plan with watermarked exports, paid credit plans) generate video clips from text and images, and Kling 4.0 makes native 30-second clips with keyframes, sound effects and lip sync. Luma AI (free tier) does photorealistic video alongside image and 3D generation. Descript (free tier, from $15/mo) edits video by editing the transcript, which is handy for devlogs. Framefields is open source (Apache-2.0) and lets coding agents write motion graphics in TypeScript and render MP4s. HeyGen (free tier, from $29/mo) and Synthesia (from $30/mo) make AI avatar presenter videos, which suit explainers more than gameplay trailers. Prices are as listed by each vendor, in USD, and can change, so check before you commit.
