Create a retro poster videoThe retro poster look borrows from mid-century travel and advertising posters: a few flat colors, bold simplified shapes, long shadows, sunbursts and the slightly uneven grain of screen printing. Every frame reads like something you could frame and hang. It is built for nostalgia, so it suits travel stories, the space race, the golden age of rail and the big moments of the twentieth century.
ShortFast makes the whole video from a topic or your pasted script. It writes the script or keeps yours unchanged, adds a narration voice, captions and music, and draws every scene as a new AI image in the poster style. Before drawing, the scene planner sets one limited palette and the recurring places and vehicles, so a video about a train journey looks like a single poster series, not a mix of eras.
Start from an idea such as "The golden age of rail travel", or paste a script you already wrote and ShortFast keeps your words.
Every scene gets its own picture, and a shared palette, setting and recurring characters keep each image in the Retro Poster look from the first scene to the last.
Pick one of 21 narration voices. Captions are burned in, and the Retro Poster defaults (natural pace, background music, transitions) are already set. You can change any of them.
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.
Travel posters were designed to be understood from across a station platform in a second or two. They use a handful of colors, one dominant shape and a clear horizon. That same economy works on a phone screen. A viewer scrolling past gets the whole scene at a glance, a rocket against a pale sky or a mountain lake at dawn, before the first caption appears.
The style also carries a mood of optimism. Mid-century posters sold the idea that the future and the open road were exciting, and that feeling comes along with the look. It makes topics like how the space race was won or the story of America's national parks feel like an adventure rather than a lecture.
Because the palette is limited, consistency comes easily. Four or five colors repeated across every scene make a video feel designed rather than assembled, and keeping the same palette across a whole series makes the channel recognizable in a crowded feed before anyone reads the title or hears the voice.
Places are the strongest subject: cities, national parks, coastlines, famous railways and ocean liners. A series such as a classic travel destination per video gives you a new poster set every time, all in the same visual language. History topics set roughly between the 1920s and the 1970s fit naturally too, since the style comes from that period.
It also works for transport and engineering stories, from the golden age of rail travel to the first jet airliners, and for nostalgia formats like iconic moments of the 20th century, one per video. The simplified shapes suit landmarks, vehicles and landscapes better than people, so lean on those.
It is less suited to intimate stories centered on faces and emotion, since poster figures are deliberately simple. Current tech, finance and news topics can look oddly dated in it, unless the retro contrast is the point of the video. And if a scene needs fine detail or dense information, the flat look will simply leave it out.
The defaults here are a natural pace, a new image around every five seconds when the idea moves on, with music and transitions on. Poster images are simple enough to read quickly, but each one is composed like a finished piece, so a steady rhythm lets it land without dragging. A light, upbeat music bed suits the travel mood. All three settings can be changed.
Write the script as a sequence of places or moments, each one a potential poster. "The train leaves Chicago at dawn. By noon it is crossing the plains. By evening, the Rockies." Lines like that give the scene planner a clear subject for every image. For a 60 second video, about a dozen scenes is a comfortable number.
Open with the biggest, most iconic image in the story, then move forward in time or across the map. Ending on a present-day contrast, such as what the station looks like now, gives the nostalgia a point. For longer travel pieces, 16:9 at 2 to 3 minutes suits YouTube, while 9:16 fits Shorts, TikTok and Reels.
Give ShortFast one theme and it makes a new retro poster 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:
