How long should a game trailer voiceover be?

Most sit between 30 and 60 seconds, which is roughly 75 to 150 spoken words. Write the script, read it out loud with a timer, and cut adjectives before you cut ideas. A minute of copy that has to be rushed to fit will sound rushed in the render too.

Can I export each trailer line as its own audio file?

There is no per-line export. The chapter is the unit: one click renders a chapter into a finished MP3, and each chapter downloads on its own. If you want a single beat as a separate file so you can re-render it after the edit changes, put that beat in its own chapter.

Should I add the music inside AudioProducer.ai or in my video editor?

For a game trailer, in your video editor. We place sounds, but there is no per-cue volume control and no automatic ducking, and a game trailer also has gameplay capture that has to sit under the read. Export the voice on its own and balance everything against picture where you can hear it.

How to Make a Game Trailer Voiceover With AI

A game trailer voiceover is a short scripted read, usually 30 to 60 seconds, that you generate as an MP3 and drop onto the timeline in your video editor. In AudioProducer.ai the steps are: paste the script, pick one voice, place the pauses where your cut needs room, generate, and download the chapter as an MP3. The mix against music and gameplay audio happens in the video editor, not here. We hand you the voice file and you take it from there.

The trailer read is a different job from your in-game lines

If you have already cast NPCs, you have voices that live inside the world. A shopkeeper greets the player. A rival taunts. Those lines are performed to another character, and the player overhears them. A trailer line is addressed to a person deciding whether to follow the game, and nobody inside the world is speaking it.

That changes what a good take sounds like. In-game dialogue can be loose and specific because the scene carries it. A trailer line has no scene around it, so it has to be legible on its own and paced to a cut the listener has not seen yet. Our guide on how to voice NPCs in your indie game covers the in-world side, and how many voice lines an indie game needs covers scoping the script. A trailer sits outside both counts. It is one short piece of copy that never ships in the build.

Write to a cut you do not have yet

Most trailers get their script before they get their edit, which means writing blind and then fitting the picture around the read. Two habits make that survivable.

Write in beats, one paragraph each, and time them out loud. At 30 to 60 seconds you have room for roughly 75 to 150 spoken words, which is less copy than it sounds like. A beat is a single idea: what the game is, what the player does, what makes it strange, when it arrives.

Then decide how much granularity you want at export time. Our export unit is the chapter. One click renders a whole chapter into a finished audio file, and each chapter downloads on its own. For a single-voice minute, one chapter is all you need. If you expect the edit to change and want to re-render one beat without touching the rest, make each beat its own chapter and download them separately. There is no per-line export, so the chapter split is the lever.

Pick the voice your game already uses

The reflex is to reach for the voice that trailers in your genre use. That is worth resisting if it does not match the thing you actually built. A weighty cinematic read on a bright puzzle game sets an expectation the first minute of play will break.

You can browse and preview the whole library from the Voices page before you commit anything, and if you have already assigned a narrator or a strong NPC voice in the game, reusing it makes the trailer sound like the game. Our notes on auditioning voices before you commit and on keeping a voice consistent across a long project both apply here. If you want the read in your own voice, cloning is available on the same page, and it has to be your voice or one you are authorized to use.

Pick one voice and let it carry the whole minute. Swapping narrators inside 45 seconds reads as an accident.

Put the pauses where the edit needs room

A trailer read with no holds in it is hard to cut to. The editor ends up slicing silence in by hand, and the seams show. You can build the holds into the render instead.

Pauses work at several levels. Under Edit Project you set a default paragraph pause that fires at every paragraph break in the project, which is why writing in beats pays off twice. Any single paragraph can override that default when one beat needs more air before the next. An inline pause drops a gap mid-sentence for the hold before a title card or a logo sting.

One trap to know: multiple consecutive blank lines count as one pause. Hitting return four times does not buy you four gaps. Set the length instead of stacking breaks. Our guide on pauses and dramatic timing goes through the levels in more detail. If your trailer has a character line in it rather than pure narration, you can attach an emotion to that individual line so it does not read flat next to the narration around it.

Keep the voice track clean and mix in your video editor

This is the part worth being exact about, because it runs against the usual advice. AudioProducer places sounds. There is no per-cue volume slider and no ducking that pulls a bed back under speech automatically. What you choose is which cue, where it sits, and whether it exists at all.

For a trailer that ships as audio, layering a bed inside the project is reasonable, and that is what our guides on the audiobook trailer and the podcast trailer describe. A game trailer ships as video, and your video editor already has level control, plus the gameplay capture that has to fit under the read too. Generate the voice on its own, export it clean, and do the balance where you can actually hear it against picture.

What a trailer costs you in words

A 45 second script is a small amount of text, so this is one of the cheapest things you can run through the app. Rewrites in your document cost nothing; only generation consumes words, so settle the copy before you render it. You can start free with 1,200 words and no card, which covers a short script plus several takes, and paid plans start from $39.99 per month.

When the read is right, download the chapter MP3 and bring it into your editor. We do not upload anywhere for you, so the store page and the showcase submission stay in your hands.
