AI Trailer Maker FAQ
What does the AI Trailer Maker do?+
You upload long footage, and the AI picks the best moments and cuts them into a trailer. Up to 10 videos and 60 min of footage (15 min on a free account). You review the picked moments before anything is rendered, then add transitions and a soundtrack.
How long can the trailer be?+
Three lengths: 30–60 s, 2–3 min, 3–5 min. A length is offered only when your footage is long enough for it (about 3 times the trailer length), so a short upload shows the shorter lengths only.
Can I change what the AI picked?+
Yes. Before the render you can review the moments, reorder them, trim them, swap one for another and set the transition at each join.
Which formats and ratios?+
The trailer comes in 6 ratios: Original, 16:9, 9:16, 1:1, 4:5, 21:9. You can upload videos of up to 2 GB each. Transitions: Cut, Crossfade, Dip to black, Flash, Slide/Whip, Zoom, Blur. Captions and title or end cards are optional.
How does the soundtrack work?+
The AI scores a soundtrack to the finished cut, from 5 credits for a 30 s cut. Or upload your own track (up to 50 MB) at no charge.
How much does it cost?+
From 12 credits (30–60 s) to 30 credits (3–5 min); a soundtrack from 5 credits. Each length shows its price before you start.
Is it free?+
You can start with a free account. A free account takes up to 15 min of footage and makes up to 2 renders per project; credits pay for the trailer itself. A paid account takes up to 60 min of footage. Renders made on a free account carry the Inflyu watermark. Spending credits needs a verified email.
Do I need a subscription?+
No. You can pay as you go: credit packs are one-time purchases and their credits never expire. If you would rather have a steady supply, the monthly Starter ($7.99), Creator ($19) and Pro ($49) plans refill your credits each month, and you can cancel anytime. Unused monthly credits do not roll over.
