Upload a PPTX or PDF deck and tell ngram who the video is for. Review the plan and script it proposes from the deck, then approve production. Refine the result through chat or the full editor.
Video generation uses credits. Review your estimate in ngram. MP4 downloads require Basic or higher.

How it works
Upload the source deck, choose AI Slides, review the scene plan, and export the finished video. The deck remains the input; this workflow does not generate a replacement presentation file.
Upload a PPTX or PDF deck as source material. ngram proposes a video plan that you can review and adjust before production.
AI Slides gives the draft a deliberate presentation rhythm. ngram plans narration, captions, pacing, and transitions across the scene sequence.
Review the plan containing the script before rendering, then revise narration or scenes in chat. Open an independent full-editor copy for canvas or timeline changes; later chat and editor-copy edits do not sync.
Render and download the finished video as MP4. You can also publish it through a connected channel or share the hosted ngram video link.
Output controls
ngram uses your deck as source material to propose a video plan, including the script and scenes. Review the plan, request any changes, and approve it to start production.
AI Slides uses a deliberate presentation rhythm instead of continuous photomotion. Adjust scene timing when a dense slide needs more room or a simple point should move faster.
ngram drafts narration from the slide content and the audience brief. Choose a voice, revise the wording, or re-voice an affected scene from the updated script.
Captions are generated with the video and styled from the active brand kit. Review their wording and timing alongside the narration and scene edit.
ngram applies transitions between slide scenes based on the content flow. The result keeps the deck's structure while giving the video a more natural visual handoff.
The active brand kit guides the video's logo, colors, fonts, motion style, captions, intro, and outro. It does not produce a redesigned presentation file.
Translate the script, captions, and on-screen text, then generate voiceover in the target language. Each localized result remains a video project.
Change one slide scene through chat or the script editor. For canvas or timeline work, open an independent editor copy and finish that version there.
