Prompt to video
An AI trailer maker gives a teaser somewhere to start when there is no footage yet. Generate the establishing shot, the turn and the reveal, then use the timeline to build the pace around them.
Generate the key shots with an AI trailer maker
A teaser needs an establishing frame, a turn and a reveal. Make those three and let the cut suggest the film around them — implication is the whole form.
Real prompt, real output. Only the wait is sped up — a render takes a few minutes.
Why it holds up
Escalation is a timeline job
Hold the first shot, shorten every one after it, then cut to black before the title. Trims and speed changes are what build that pressure, and no preset can guess where your beats are.
The end card is a generation too
Bunsy makes stills as well as video, so the closing frame is one more render you drop on the timeline and hold, with the music bed and a read line running underneath it.

Questions
How long can a teaser from the AI trailer maker be?
Models produce a few seconds per shot, so a teaser is naturally a handful of cuts strung together. That is also the honest length for the format — a trailer that outstays a minute stops being a trailer.
Can I make a trailer for a book or a game?
That is where generation earns its place, because there is nothing to film. Keep the world consistent by starting later shots from stills you already generated rather than from fresh text every time.
Will the title text come out readable?
Text inside a generated image is the least reliable thing any of these models do. Treat a generated card as a background and expect to retry it, or hold a plain frame and let the voice carry the name.
