AI YouTube video generator for narrated 16:9 videos
Long-form YouTube rewards depth: viewers come for a story or an explanation and stay for the pacing. ShortsMachine generates landscape 16:9 videos up to 5 minutes long with a full script, a new AI-generated scene every few seconds, narration and captions.
Use it for complete short videos, or to produce chapters and B-roll segments you combine into longer uploads.
Good long-form formats
- History and mythology narrations.
- Top-10 and countdown videos.
- Science and technology explainers.
- Fiction and story channels.
Planning a 5-minute video
Give the script writer a structure: an intro hook, three to five main points, and a conclusion. At 5 minutes on a 10-second model you get about 30 scenes, so ask for visual variety — different locations, angles and moments — to keep the video moving.
Landscape-only models such as MiniMax H3 become available in 16:9, alongside every other model.
Keeping a long video watchable
- Open with a question you only answer at the end.
- Signpost the structure in the narration: “first…, next…, finally…”.
- Ask for visual variety: different locations, close-ups and wide shots.
- Use models with longer clips (Kling, Wan 2.7, HeyGen, Grok, FLUX 3 Max) for fewer, smoother cuts.
Budgeting long videos
A 5-minute video uses five times the credits of a 1-minute one. Test topics as 1-minute videos first and expand the ones that perform. On Premium, 2,000 monthly credits cover roughly 24 minutes on Wan 2.2 Fast or about 4 minutes on Kling 3.0.
