Upload your screenshots to ngram and the AI arranges them into a storyboard with transitions, timing, and optional voiceover. Review the sequence, adjust pacing or narration, then export a polished video in 16:9, 1:1, or 9:16 format - all in under 5 minutes.
Screenshots Sit in Folders While Your Audience Waits for Video
You took 15 screenshots documenting the perfect workflow. Every screen, every button, every state captured. But screenshots do not play, do not narrate, and do not hold attention the way video does. Turning those images into a video walkthrough with traditional tools means importing each frame, setting timing, adding transitions manually, and recording voiceover separately.
ngram takes your screenshots and builds a branded, narrated video walkthrough in minutes - no video editor, no voiceover session, no design review.
How it works
Upload your screenshots
Drop PNG, JPG, or WebP files into ngram. Upload them in the order you want them to appear, or rearrange after upload.
AI builds a video storyboard
ngram arranges your screenshots into scenes with transitions, timing, and optional zoom effects on key areas of each image.
Add narration and refine
Add AI voiceover from a text script, adjust pacing per screenshot, and apply your Brand Kit for consistent styling.
Export the finished video
Download in 16:9 for docs and presentations, 1:1 for social, or 9:16 for mobile - all from one screenshot set.

Screenshots are the default way teams document product workflows, bug reports, and feature updates. But static images cannot show timing, transitions, or context the way video can. Converting screenshots to video bridges that gap - turning flat documentation into content that holds attention and communicates step-by-step processes clearly.
Why screenshots alone fall short for product communication
A 12-screenshot guide in a help article forces the reader to scroll, zoom, and mentally connect each step. Video walkthroughs show the same flow in 60 seconds with transitions that guide the eye and narration that explains context. Teams that add video versions of their screenshot guides report higher completion rates and fewer support follow-ups.
How ngram converts an image sequence to video
Upload your screenshots in order and ngram's AI analyzes each image to determine what it shows - a form, a dashboard, a settings panel, a confirmation screen. It builds a storyboard with appropriate timing per screenshot (more time on complex screens, less on simple confirmations), adds transitions between scenes, and optionally generates voiceover narration from a text script you provide.
Smart zoom makes screenshots cinematic
Full-screen screenshots shown at 1:1 scale lose detail on smaller screens. ngram's smart zoom detects key UI regions in each screenshot - buttons, form fields, navigation elements - and creates subtle pan-and-zoom movements that direct the viewer's attention. The result looks like a professionally filmed product walkthrough, not a slideshow.
From one screenshot set to three video formats
Your help center needs 16:9 landscape. LinkedIn wants square. Instagram and TikTok need vertical. ngram exports all three aspect ratios from a single screenshot project. Each format gets its own optimized zoom, crop, and caption placement so the important parts of each screenshot stay visible regardless of the output dimensions.
Screenshot video maker vs traditional video editors
Traditional video editors like Premiere or Final Cut treat screenshots as static assets on a timeline. You set duration manually, add transitions manually, and record voiceover in a separate tool. ngram is purpose-built for this conversion: upload images, get an AI-generated storyboard with timing and transitions already set, adjust what needs adjusting, and export. The workflow takes minutes, not hours, and the output maintains brand consistency through your Brand Kit.
