Hollywood pacing on a creator budget

Major studio trailer houses — Trailer Park, Mark Woollen, AV Squad — charge $50K-$250K to write, edit, sound-design, and license a single trailer. The first step in that process is the script: which beats land where, what the VO whispers vs roars, when the music drops out. Free.ai writes that script in 15 seconds. Combined with /voice/tts/ for the deep trailer voice and /music/generate/ for an epic-orchestral track, you can push a passable indie-film, game-launch, or book trailer to YouTube without spending a dollar. The polish belongs to your editor — but the bones are ready.

Indie film + festival cuts

Submit to Sundance / TIFF / SXSW with a marketing trailer that does not look like a student film. The script is the cheap part to fix; the shoot is the expensive part.

Indie game launch trailers

Steam page conversion lives or dies on the trailer. The Game Awards-style 60-second cut with a money-shot reveal at 0:48 is its own art form — our script generator nails that beat structure.

Book trailers

Publishers used to film these for $20K. Self-published authors now do them with stock footage + AI VO + a tight 60s script. Pair with /image/ for cover B-roll and /music/generate/ for ambient bed.

Podcast trailers

Spotify and Apple Podcasts run 30s trailer cuts in front of related shows. Your launch trailer needs to hook in 7 seconds and tease the season's stakes by 25.

Product launch hype reels

Apple-style keynote-tease format. Black screen, single object reveal, gradient transition, hero close-up, price card. Our generator structures the beats; your designer renders the slabs.

Conference + event hype

Re-Invent / WWDC-style 30-second event trailers. Tease the speakers, name the city, hit the date hard. Repurpose at every email send + social cross-post.

AI Trailer Generator — FAQ

Free.ai AI Trailer Generator writes a Hollywood-style trailer script from a synopsis - cold open, world-building montage, inciting incident, rising-action beats, title-card reveal, money-shot climax, release-date card. Pace beats are annotated with suggested music cues (strings building, silence, bass drop) and edit-room pacing notes.

No - the output is a structured trailer script + music-cue timeline you take into Premiere / DaVinci / CapCut. For AI-rendered video shots to match the script, render individual scenes at /video/text-to-video/ and stitch them. For the voiceover use /voice/tts/ with a gravelly "movie trailer voice" preset.

Yes - /v1/chat/ call using free Qwen 2.5. A full trailer script costs ~1,500 tokens. Premium Claude / GPT-5 cost more but produce the tight punchy Don-LaFontaine-voice copy that makes a trailer feel real.

Hollywood trailer houses (Trailer Park, Mark Woollen, AV Squad) charge $50-250K per trailer - that is the script + edit + licensing + sound design as a package. Free.ai gives you the script stage for free. Combined with /voice/tts/ trailer voice and /music/generate/ (epic orchestral), you can produce a passable indie-film / game trailer for zero dollars up to the shooting / editing budget.

Action, thriller, horror, drama, sci-fi, romantic comedy, documentary, superhero, indie art film, kids / family, and gaming. Different genres get different beat structures - horror leans on silence-then-sting, RomCom leans on chemistry montage, Action on escalating set pieces.

Yes - game launch trailers, podcast trailers, product-launch hype reels, SaaS-company "manifesto" videos, event promos, wedding save-the-date videos, book-launch teasers. Any project that benefits from a 60-90 second emotional arc.

Yes - every beat is annotated with music suggestion (tempo, instrument, emotion). Copy the cues into /music/generate/ and generate an epic-orchestral track for the trailer. Classic trailer music is 60-90 seconds long, rising through two climax points - our music generator respects that structure.

The output marks VO lines in CAPS. Copy each VO line into /voice/tts/ and pick a deep male voice (the "movie trailer voice" archetype is called "Don LaFontaine voice" - resonant male baritone). For female trailer VO, the "epic documentary" female voice works well. Mix the TTS output under the music in /video/editor/ or your NLE.

60-90 seconds is the industry standard for film trailers. 30 seconds for TV spots. 15 seconds for social cutdowns. Our generator offers all three lengths - pick based on your target platform. YouTube pre-roll: 15-30 s skippable or 60 s unskippable.

Yes - pick "Teaser" (30-45 s, high mystery, no plot reveal) or "Full trailer" (90-120 s, 3-act arc) at the length selector. Teasers land 6-12 months before release; trailers land 6-8 weeks. Our beat structure changes per length.

The script itself is original - generated fresh per your synopsis. But the MUSIC you pair with it is a different story: do not use copyrighted soundtracks (Hans Zimmer, John Williams) in published trailers without licensing. Generate the score at /music/generate/ (our output is Apache 2.0 via ACE-Step) or license through Artlist / Musicbed.

Yes - /v1/chat/ with the trailer-writer system prompt. The output is markdown with beat timestamps you can parse. Useful for studios producing many reel-based cutdowns. Bearer auth, /api/ snippets.
