The documentary look is real footage under a calm narrator: ships in a lock while the voice explains how the Panama Canal works, departure boards and runways for the world's busiest airport, the style's own examples. Because the pictures are real, viewers trust what they see, which is why the style suits company stories, places and how things work.
ShortFast writes the script from a topic or keeps yours word for word, picks one of 40+ voices and gives each scene a licensed stock clip matched to its line, with nothing to attribute. Captions are burned in and music is added, in 9:16 for Shorts, TikTok and Reels or 16:9 for YouTube. A minute of video costs about 24 credits, the least of any style, so Starter's 2,000 monthly credits cover about 80 one-minute videos.
How it works
Making a documentary video
- 01
Describe the topic or paste a script
Start from an idea such as "How the Panama Canal actually works", or paste a script you already wrote and ShortFast keeps your words.
- 02
Real footage for every scene
The AI splits the script into scenes, searches licensed clips for each line and picks the best match. A scene about a named real place or thing can get a public-domain photo instead.
- 03
Voice, captions and pacing
Pick one of 40+ narration voices. Captions are burned in, and the Documentary defaults (normal pace, background music and transitions) are already set. You can change any of them, swap any clip, or upload your own.
- 04
Download, post or run a series
Download the video, auto-post it to TikTok, YouTube Shorts and Instagram Reels, or turn the theme into an automated series that makes a new episode on a schedule.
Where the pictures come from
ShortFast searches Pexels and Pixabay together for each line, and an AI looks at the candidates' thumbnails to pick the clip that fits. When a scene is about a named real place, building or thing, it can use a photo from Wikimedia Commons instead, and only one that is CC0 or public domain, never one marked with restrictions such as logos and trademarks.
When nothing fits, the scene gets a generated still made to look like a photo, at no charge. That keeps the video complete, but it is an AI image in a documentary, so check every scene before you post: swap the still for another clip, or upload a clip of your own into that scene.
Writing a documentary short that the footage can carry
Give the video one story with a turn. A company story rises, hits the decision that changed it and lands on what happened next; a place gets one reason it's remarkable; a how-it-works video follows the process in order. Around 150 words fill a minute, so one story told well beats a list of facts.
Write lines that footage can show. 'Container ships wait their turn to enter the locks' is far more likely to find a real clip than 'the canal's economics shifted', and lines with nothing to film are where generated stills creep in. Stock shows a kind of thing, a lock, a factory, a trading floor, rather than the exact one in your story, so say 'locks like these' when the clip isn't the place itself.
Real names, real events and labels
Documentary viewers take what they hear as fact, so check names, dates and figures against the company's own filings, the museum or the official source before you post, and keep rumors out. A clip of a generic office over a line about one company is illustration; a clip presented as that company's headquarters, when it isn't, misleads.
Real footage needs no AI label. A generated still you keep is different: YouTube requires disclosure of AI content that 'seems realistic', and TikTok requires a label on 'all AI-generated content that contains realistic images, audio, and video' (both checked 24 October 2026). ShortFast sets no AI label when it posts, so either replace those stills or turn the labels on yourself.
Run it as an automated series
Give ShortFast one theme and it makes a new documentary video on a schedule, every day, twice a day or a few times a week. Each episode covers a new topic on the theme, and the video is emailed to you or posted to your accounts. Themes that work well in this style:
- The story behind a famous company, one per video
- Wonders of the world, a new place each time

OpenFAQ
Common questions
- Where does the documentary footage come from?
- From Pexels and Pixabay, searched together for each line, with an AI picking the best clip from the candidates' thumbnails. Scenes about a named real place or thing can use a CC0 or public-domain photo from Wikimedia Commons. There is nothing to attribute.
- What happens when no clip fits a scene?
- ShortFast makes a still that looks like a photo for that scene, at no charge, so the video is never missing a picture. Because it's AI-generated, review it: swap it for another clip, upload your own, or label the video if you keep it.
- How much does a documentary-style video cost?
- About 24 credits a minute, the lowest of any style, so Starter's 2,000 monthly credits cover about 80 one-minute videos. AI video costs far more: about 370 credits for a 50-second video.
- Documentary or Mixed: which should I pick?
- Documentary keeps real footage in every scene, apart from a still when nothing fits. Mixed uses footage for real places, products and events and an AI image for abstract ideas, and those images are made to look like photos. Pick Documentary when every picture should be real, Mixed when the script has ideas footage can't show.
