ngram
ngram creates videos for product explanations, training, onboarding, and launches from a brief and source material. You can start with a description or bring documents, screenshots, a webpage, or a screen recording. The official product page describes a workflow that keeps the generated video open to revision.
Approving the story before production
Describe the audience, message, and action you want viewers to take. ngram proposes a script and production plan for you to review before it creates the video. You can request changes to the plan or approve it to begin production.
That approval step is useful when the video explains a specific feature or procedure: supply the actual facts and steps, then check that the proposed story uses them. The service's examples include launch films, educational explainers, and operational process videos. Treat those examples as starting points for the kind of communication you need, rather than as evidence of the result your brief will produce.
Revising and downloading a video
After generation, you can describe a change in chat or pin a request to a moment with Make changes. The current workflow guide advises naming the moment and the exact change, then reviewing the next output. Revisions can consume credits.
The Versions control lets you view and download earlier outputs; selecting one does not restore or revert the project. A playable preview can also appear before the final MP4 download is ready. Keep the conversation open while download preparation finishes. Finished videos export as MP4, with GIF downloads for short videos and aspect ratios that depend on the selected models.
Understanding credits and plan boundaries
The pricing page gives the Free plan a one-time 600-credit allocation without requiring a card. Generation allowances measure premium AI-generated footage, not the final video's length. Premium video generation starts at ten credits per second, and agentic editing uses one credit per second.
Paid plans include unlimited manual editing and exports under a fair-use policy. Basic, Premium, and Ultimate differ in generation capacity, export resolution, and access to branding or custom presenter features. Hosting, embedding, and player customization have a limited rollout. Polls, quizzes, and call-to-action buttons work in supported shared playback; a downloaded MP4 remains a standard video without those interactive elements. Check availability for your account before building a delivery workflow around hosted features.
